Frequently Asked Questions (FAQs)

Search and Consumptions

What do the colours of the foods mean?

The colours are derived from the energy density (kcal/kJ per 100 grams) of the food. You can see the colours of a traffic light: green = low, yellow = medium, red = high energy density. Please note that the colours don’t indicate healthy or unhealthy foods.

I’m weighing all foods and entering all consumptions using their exact weight. Is there an option to directly start using “grams”, instead of switching from a serving size every time?


 Yes, when entering a consumption, you can open the menu at the upper right corner (three dots) and pick “Settings”. In this screen, untick “Propose Servings”. Starting with the next consumption, “grams” will be activated by default.

Foods

I’m missing food XYZ! (Calories!)

When using the free version of the app, the databases of the Pro Platinum version will be searched too. If there are foods in these additional databases that match the current search, there will be an extra entry at the end of the search results. When you select this entry, a dialog will display a list of all additional hits. Maybe the food you’re searching for is already part of a database of the Pro Platinum version.

If the food is not part of the Pro Platinum version, you may enter it yourself. It’s very easy to add a new food or recipe to the database.

The nutritional values of food XYZ seem to be different!

Well, this may be caused by several reasons:

  • There are foods that don’t have definite nutrition information. In particular, with discounters, the same product may be produced by different local producers. The food is sold with identical names and identical barcodes, but different nutrition values. Especially with milk, cheese and yoghurt, this is relatively common.
  • A barcode can not be assigned to a single product. Unfortunately, some discounters use a single barcode for a “family” of products. This often occurs with yoghurt or juice in different flavours.
  • The nutritional values of foods change over time. It often happens that the nutritional values of the discounters change when the producer behind them changes. Similarly, food formulations may change over time, resulting in altered nutrition values.
  • There are products that use a different recipe depending on the country (depending on the legal framework) and thus have different nutritional values. Example: sweets.
  • Foods are subject to natural variations. For common foods (i.e. without brand or manufacturer name) all displayed values are representatives of the particular food, but they may differ in concrete cases. Respectively, the values of food packages and nutrition lists differ. This isn’t an error, but natural and unavoidable.
  • The nutritional values of raw and processed foods differ. That’s natural too, because the food changes during the processing. Often sugar will be added, or water, for instance. Heating food changes its nutritional values, too.
  • The nutritional values of mineral waters strongly differ from brand to brand. Please add the nutrition values of your personal mineral water to the database by adding a new food.
  • Although all our care and precaution, it’s unavoidable that the food database contains errors. MyCalorieApp: Please edit the nutrition value of the food. Our support team will review the changes and then approve. “Calories!” and “Purine!”: Please send your feedback directly from the app (consumption or food, open the top right menu, Feedback).

I’m missing a barcode scanner. (Calories!)

We’ve introduced a barcode scanner in Calories! version 9.0. Please note that the scanner is a feature of the Pro Platinum version.

Why does “Purine!” not provide a barcode scanner?

Foods from the supermarket, unfortunately, have no purine or uric acid values on the packaging. As a result, we cannot add supermarket products to the database (except for special cases, such as mineral water). So it makes no sense to offer a barcode scanner – it wouldn’t find anything.

If you want to use a calorie counter app with a barcode scanner, we can recommend “Calories!” or MyCalorieApp to you. However, you will not find purine / uric acid levels there.

Recipes

How can I enter a new recipe?

Open the menu at the upper left corner, pick “Add Recipe”, enter a name and choose a category. Tip: You can reach all sub-categories by clicking on the icons or texts on the left side. Press the “+” sign at the upper right corner to add a new ingredient. Repeat this until you added all ingredients. The recipes of the list may be altered too – just select one. When the recipe is complete, press the disc icon in the lower right corner. Done!

How can I alter the ingredients of a recipe?

A recipe can be edited as every regular user-defined food can. Just press the pencil in the search/browse view.

What are lists, and how do they differ from recipes?

A list is a collection of foods that are either similar or can be related to a common topic. For example, you can create a “breakfast list” and put foods there that you often eat for breakfast. Other examples: cereals, jams, baking ingredients, soft drinks, juices, dips, barbecue sauces, ….

With the help of lists, you can create your own groupings of foods. If you additionally use the favourites, you can practically create your own directories inside the favourites.

A recipe is always consumed as a whole (cake, cooked dish, etc.). In a list, you always consume only one food (or part of the food). A list is more like a collection of foods. You group foods together and then choose one of them.

If I change one of my recipes, all previous consumption entries automatically change. Why is this the case, and how can I prevent it?

A recipe is basically comparable to a food. The main difference is that the nutritional values are calculated from the recipe ingredients, whereas they are defined directly for a food.

If you change a recipe (or a food), there are two possibilities:

(a) You want to correct, i.e. something was not right before. In this case, all previously created consumption entries should be adjusted.

(b) You want to change the recipe, which basically means that it is a new recipe. In this case, the previous consumptions should remain unchanged.

The app always assumes case (a), i.e. that it is a correction.

If this is not desired, you should create a new recipe. You can copy an existing recipe or start from scratch if necessary.

How to copy an existing recipe:
– Open the lists and recipes, e.g. by clicking on the list symbol (blue) on the start page or in My Day.
– Press the pencil to the right of the recipe name.
– Open the menu at the top right.
– Click on “Create copy”.

The copied recipe is independent of the original recipe. The same applies to the respective consumptions.

New since Calories! 10.5.4 and Purin! 2.5.4: It is possible to split existing consumption entries from recipes. The consumption is broken down into individual consumptions according to the recipe ingredients.

The split consumption entries are independent of the recipe. This, in turn, opens up the possibility of changing the original recipe without affecting existing consumption entries.

If you want to use this method, you should proceed as follows:
– Whenever (!) you have created a consumption of the recipe, you should split the consumption.
– Select the consumption in My Day (and only this one consumption).
– The symbol for splitting appears at the top right (an arrow that splits into two arrows).
– Click on the split symbol. Attention: No confirmation dialogue is displayed!

However, splitting a recipe consumption comes with a restriction. The water reduction of the recipe cannot be taken into account in the split consumptions. This would require a consumption entry with a negative water value, which does not exist. Please note that splitting a recipe consumption may affect the water balance for the day.

Note: The function for splitting recipe consumptions is not available for MyCalorieApp.

Sports

How can I enter my exercises?

Go to “My Day”, then press “Add new exercise…”. Browse using the categories or search for your sport or physical activity. Then enter the duration of the exercise. If you measured the consumed calories yourself, e.g. using a pulse measuring watch, enter the value at “Energy”. Save, done!

Similar to the foods, favourites for sports are supported. Furthermore, it’s possible to add your own sport or physical activity (“Calories!” only!). Then it’s up to you to define it using the metabolic equivalent (MET, see Wikipedia) or a weight-independent energy value per hour.

Google Health Connect

I’ve connected the app to Google Health Connect successfully, but no exercise values are transferred. What can I do?

In the default settings, the app stores only the exercises from Google Health Connect that contain an energy value. If you want the app to store all exercises from Google Health Connect, then please deactivate the switch “Ignore Exercises w/o Energy Value” (menu at the upper left corner, Settings, Google Health Connect). The app then calculates the energy values of the exercises. Please be aware that the calculated energy values of the app may differ from the displayed values in the app that originally created the data.

Another possible cause may be the lack of transmission by the app that generates the data.

If the problem has not yet been resolved:

Please check in the Android settings whether Calories! / Purine! / MyCalorieApp has accessed Google Health Connect:

  • Android Settings > Privacy & Security > Privacy Settings > Health Connect > View all recent accesses
  • Depending on the device manufacturer and Android version, there may be differences in the menu structure.

If the list in the Android settings shows the app’s data accesses correctly, but nothing is displayed in the app, then the app is probably not receiving any data from Health Connect. Please check whether any data is available in Health Connect:

  • Android Settings > Privacy & Security > Privacy Settings > Health Connect > Data and Access
  • Please select “Sport” or “Weight”, depending on which data is missing.
  • You can now select a date or a time period.

Sometimes the data is not available in Health Connect because the app that generates the data does not transfer the data to Health Connect. We are aware of several cases in which it sometimes takes several days for the data to be available in Health Connect (and therefore also in Calories! / Purine! / MyCalorieApp), e.g. new weight values via Withings. Please check the entire transmission path to ensure that the data is available at every intermediate step.

After the transfer of the exercises from Google Health Connect, the app displays invalid activities, e.g. “Automobile or light truck driving”. Why?

Probably you’re using only the Google Fit app without any fitness tracker. The Fit app attempts to determine from the movement of the mobile phone which activities you have performed. This works very well in most cases, but sometimes it doesn’t. Our app transfers the data from Google Fit (or Health Connect), but it has no chance to verify its accuracy.

What fitness trackers and scales does Google Health support?

Unfortunately, we don’t know a usable list of all compatible devices. Please inquire directly at your selected hardware manufacturer for Google Health Connect support.

What can I do when my fitness tracker doesn’t support Google Health?

Maybe FitnessSyncer is a solution for you! It supports Fitbit and JawBone, among others.
https://www.fitnesssyncer.com/

Or Health Sync: https://play.google.com/store/apps/details?id=nl.appyhapps.healthsync

Why can I only see Health Connect data up to 30 days in the past?

Unfortunately, this is a limitation of Google Health Connect. Health Connect allows our apps to read records with a start time for up to 30 days before the first successful Health Connect connection. Again, these are the rules of Google Health Connect. Our apps could look as far back in time as they want, but we don’t receive the data.

Note: If the app is uninstalled and then reinstalled, the date is reset, which marks it as your new starting date as if you use the app for the first time.

More information: https://developer.android.com/health-and-fitness/guides/health-connect/develop/frequently-asked-questions#time-range

Why was it necessary to switch from Google Fit to Google Health Connect?

Google discontinued the Google Fit interface in 2025. Google Health Connect is available as an official replacement.

How does the integration of Google Health Connect differ from Google Fit?

With Health Connect, Google has not only changed the interface, but the usage options also differ. The most serious change is certainly the restriction of access to the past days. Health Connect allows all apps to read data records with a start time of up to 30 days before the first successful Health Connect connection.

Again, these are the rules of Google Health Connect. Our apps could look as far back in time as they want, but we don’t get the data.

The restriction to 30 days before the first Health Connect connection has a negative impact when changing devices. If one of our apps is installed on a new device and then the connection to Health Connect is enabled, this counts as a new activation, and the 30 days apply from that day. However, older Health data records could also be accessed on the old device, as activation was carried out much earlier. Consequently, you would lose access to a considerable amount of your Health data if you changed devices.

To avoid this loss of data, we fundamentally changed the concept for integrating Health Connect.

With Google Fit, we were able to read all data as far back in time as we wanted. Our apps regarded Google Fit as an independent data source that can always provide all data. We only synchronised the data, i.e. all Fit data was only temporarily stored in our apps (buffer).

With Health Connect, we can only read the data for a limited period of time. This period can change at any time, e.g. due to a change of device. We see Health Connect as a temporary data source that can only provide certain data. The data is imported into our apps and permanently stored locally.

This results in the following advantages:

  • Changing the minimum synchronisation date does not result in the deletion of local Health data.
  • Switching off Google Health Connect (including weight or training data individually) does not lead to the deletion of local Health data.
  • Health data can now be changed and deleted.
    • Important note: Be sure to pay attention to the minimum synchronisation date! Otherwise, the changed data may be reset during the next health import, and deleted entries may reappear.
  • The health data is now part of the backup file and can be transferred manually to another device. This only applies to the Calories! and Purine! apps.

We would like to emphasise once again that all health data is only stored locally on the device. No health data is transferred to the MyCalorieApp server. Exception: When using the data transfer feature, the data will be temporarily stored on the MyCalorieApp server, see chapter “data transfer”.

The disadvantages:

  • Since the health data is only stored locally, there is no synchronisation to other devices for the MyCalorieApp app. Each device must establish its own connection to Google Health Connect.
  • Consequently, the data described above may be lost if you change devices.

If access to past data from Google Health Connect is important to you, we recommend that you switch from MyCalorieApp to Calories! We will provide a corresponding option for data transfer in the future.

How can I change the permissions for Google Health Connect retrospectively?

  • Please open the Android settings (not inside the app, but of the device).
  • Security & privacy
  • Privacy controls
  • Health Connect
  • App permissions
  • Select Calories! / Purine! / MyCalorieApp
  • Enable or disable all or single permissions
  • A confirmation dialogue may appear. Confirm the dialogue.

Something is wrong with the Health Connect data. How can I send you diagnosis data?

To send the diagnosis data to the support team, you can proceed as follows:

  1. The diagnostic function for Google Health Connect is only available as a beta version until the end of June 2025. If you are not yet a beta tester, you can sign up here:
  2. Please update the app to the latest beta version. (After registering, it may take a few hours for the update to be offered or carried out.)
  3. Please open the app, top left menu, Settings, Google Health Connect, Health Diagnostic Data.
  4. On which day did discrepancies occur? Please select the day for which the training data should be queried.
  5. Please choose your email app.
  6. Please describe at the beginning of the email which data or values you expect to see in the app.
  7. You can inspect all the data before sending. Please then send the email.

Analysis

What do the arrows in the analysis mean?

We’re using the traffic light colours: green = very good, yellow = good, red = bad. The direction of the arrow describes whether you absorbed too little or too much of a nutrient (or calories, water, etc).

Weight Diary

Is the app able to compute the body fat value if I don’t own a scale that provides this value?

No, a calculation is currently not supported.

Diet

I’m using the app to lose / gain weight. Can I enter my desired weight?

Yes, please use the diet assistant by opening the menu at the upper left corner, then “Diet Assistant”.

How can I decrease / increase the recommended daily calories?

There are two options to do this: (1) You may use the diet assistant (open the menu at the upper left corner), or (2) you set your individual daily values (Settings, Nutrition Values, Individual Daily Values).

Where can I see how many calories I saved daily / weekly / monthly?

This feature is already part of our wishlist. At the moment, there’s no specific release date, sorry.

Export and Printing

How do I set up a printer for the app?

Since Android 8 (Oreo), the Default Print Service has been available. You can find instructions on how to set up a printer here, for example:

[1] https://www.lifewire.com/how-to-print-from-android-4769907
[2] https://droidrant.com/how-do-i-change-my-default-printer-on-android/
[3] https://www.techrepublic.com/videos/how-to-easily-add-a-printing-service-in-android-10/

More information:

Note

As the subject of printer setup is quite diverse, we are unfortunately unable to offer any further support. Please contact the printer manufacturer directly if you have any problems.

Data Synchronization

How do I synchronise all data between two devices? (Calories!)

Google Drive, since Calories! V10.1 / Purine! V2.1

I recommend the following procedure:

(1) Launch the app on the first device. Open the menu in the upper left corner, choose Settings, then Backup.
(2) Select “Backup”, press “Start”
Note: The following screen will be provided by the Android OS. Calories!/Purine! has no influence on the supported functionality!
(3) Open the menu in the upper left corner, choose “Drive”.
Note: If there is no “Drive” entry, please make sure that the Google Drive app is installed on your device. Please open the Drive app for a moment and return.
(4) Choose “My Drive”.
(5) Optional: You may enter a folder of your choice.
(6) Optional: You may change the file name by clicking on it at the bottom of the screen.
(7) Press “Save”. The backup will be created and uploaded to Google Drive.
(8) Launch the app on the second device. Open the menu in the upper left corner, choose Settings, then Backup.
(9) Select “Restore”, press “Start”
(10) Open the menu in the upper left corner, choose “Drive”.
Note: If there is no “Drive” entry, please make sure that the Google Drive app is installed on your device. Please open the Drive app for a moment and return.
(11) Choose “My Drive” and navigate to the backup file. Select the backup file. Done!

Google Drive, before Calories! V10.1 / Purine! V2.1

This is the recommended procedure:

(1) Launch the app on the first device. Open the menu in the upper left corner, choose Settings, then Backup.
(2) Choose “Google Drive” at the first tab (“Backup”). Selecting a folder is currently not supported. Start the backup.
(3) If Google Drive is used for the very first time from this app and device, you have to choose the Google account to be used and confirm the access.
(3a) Please take care that the used Google account is available on both devices! Sharing data between different accounts is not supported.
(3b) Privacy: The app can access its own files only on Google Drive. The app is unable to open, read or write files and folders created by other apps.
(4) Launch the app on the second device. Open the menu in the upper left corner, choose Settings, then Backup.
(5) Select the second tab (“Restore”) and choose “Google Drive”.
(6) Click “Choose” to get a list of all available backup files. This may take a moment. Please choose a file when the list is available.
(6a) If Google Drive is used for the very first time from this app and device, you have to choose the Google account to be used and confirm the access.
(6b) Maybe the created file from step (2) is not visible yet. Google Drive has to synchronise the data between devices first. Please wait a few minutes before trying again.
(7) Press “Restore” to start the import of the backup file. Done!

Please note that all data will be erased automatically before the backup file is imported! That’s why you should avoid entering data on both devices at the same time. Otherwise, a data synchronisation would cause the loss of data.

Local Backup, since Calories! V10.1 / Purine! V2.1

To synchronise data, the manual transfer of the data to the second device is required. You may use a PC for this, or a cloud storage provider, or e-mail, or Bluetooth, etc. We recommend using a cloud storage provider:

(1) Launch the app on the first device. Open the menu in the upper left corner, choose Settings, then Backup.
(2) Select “Backup”, press “Start”
Note: The following screen will be provided by the Android OS. Calories!/Purine! does not influence the supported functionality!
(3) Open the menu in the upper left corner, choose your device.
(4) Optional: You may enter a folder of your choice.
(5) Optional: You may change the file name by clicking on it at the bottom of the screen.
(6) Press “Save”. The backup will be created.
(7) Upload the created backup file to your cloud storage provider, e.g. Google Drive, Dropbox, Box, etc.
(8) Download the backup file from your cloud provider onto the second device. For example, using the Google Drive app: search for the backup file, then click on the small “i” at the right side, then choose “Download”.
(9) Launch the app on the second device. Open the menu in the upper left corner, choose Settings, then Backup.
(10) Select “Restore”, press “Start”
(11) Open the menu in the upper left corner, choose your device.
(12) Navigate to the backup file and select it. Done!

Local Backup, before Calories! V10.1 / Purine! V2.1

To synchronise data, the manual transfer of the data to the second device is required. You may use a PC for this, or a cloud storage provider, or e-mail, or Bluetooth, etc. We recommend using a cloud storage provider:

(1) Launch the app on the first device. Open the menu in the upper left corner, choose Settings, then Backup.
(2) Choose “Local” at the first tab (“Backup”).
(3) Choose a folder, if required. You may create a new folder as well.
Tip: If you’re unable to pick a folder, this one should work in most cases (try to type it manually):
/sdcard/Android/data/org.digitalcure.ccnf.app/files/
(4) Start the backup.
(5) Upload the created backup file to your cloud storage provider, e.g. Google Drive, Dropbox, Box, etc.
(6) Download the backup file from your cloud provider onto the second device. For example, using the Google Drive app: search for the backup file, then click on the small “i” at the right side, then choose “Download”.
(7) Launch the app on the second device. Open the menu in the upper left corner, choose Settings, then Backup.
(8) Choose “Local” at the second tab (“Restore”).
(9) Press “Choose” and select the downloaded backup file. Only ZIP files will be displayed. When using Google Drive, the download folder is: “/sdcard/Download”.
(10) Click “Restore” to import the backup file. Done!

Please note that all data will be erased automatically before the backup file is imported! That’s why you should avoid entering data on both devices at the same time. Otherwise, a data synchronisation would cause the loss of data.

Data Transfer

What is the difference between a backup and a data transfer?

A backup is a copy of your data that is stored permanently. In an emergency, you can restore this version of your data at any time, e.g. if your device is defective or lost. “Calories!” and “Purine!” support the creation of backups on Google Drive and locally on your device. Note: We recommend that you back up the local backups yourself to another device or to a cloud service. This process can be automated with the help of backup apps.

A data transfer is also a copy of your data, but the focus here is on the transfer. A data transfer only has a short lifespan (1 hour) and is then automatically deleted. The data is transferred via our MyCalorieApp server. The transfer itself is very simple and requires only a few steps.

Conclusion: The focus of backups is on permanent storage for emergencies, while data transfers are only used for short-term transmission. The content is identical in both cases.

How often can I carry out a data transfer?

In the free version of the app “Calories!”, you have 2 data transfers within 12 months. This makes it easy, for example, to transfer all your data when you change devices.

The app “Purine!” and the Pro Platinum version of “Calories!” offer you 5 data transfers within 24 hours. This makes it very easy to use the app on two devices and exchange the data several times a day.

Can I restore a data transfer to multiple devices?

Yes, the number of restores is not limited. It is therefore also possible to use three devices, for example. Please note, however, that a data transfer is only available for 1 hour.

Is the data transfer a full synchronisation of my devices?

No, a data transfer is not a full synchronisation. During a data transfer, the current data status of one device is completely transferred to another. However, all existing data is deleted on the second device before it is restored.

In other words, there is no mixing of the two data statuses. It is therefore not possible to enter data on both devices at the same time and then synchronise them.

Is the data transfer saved permanently?

No, a data transfer has a lifespan of 1 hour and is then automatically deleted. A data transfer is therefore not suitable as a permanent backup.

How is data protection guaranteed during a data transfer?

There are several aspects to data protection: the anonymity of the user, security during transmission and security during storage on the server.

(1) Anonymity of the user: Each user receives an anonymous ID from the server. Although the server assigns the ID, it does not know to whom. No personal data is required to generate the ID.

The user ID can be displayed in the app at the following location:
Top left menu, Settings, MyCalorieApp server, Anonymous user ID for data transfers

A download code is required to be able to restore a data transfer on another device. The download code is also generated by the server. When the code is entered on the second device, not only is the data backup transferred, but also the user ID. From this point on, the user ID is available on both devices, i.e. the two devices are linked, so to speak. In future, it will no longer be necessary to enter a download code, and the data transfer will be even easier and faster.

Neither the user ID nor the download code allow any conclusions to be drawn about the identity of the user.

(2) Security during transmission: All data transfers are encrypted locally on the device. In addition, all communication with the MyCalorieApp server is encrypted. The data is therefore doubly encrypted during transmission.

(3) Security during storage: All data transfers are stored in encrypted form on the MyCalorieApp server.

What is the anonymous user ID for data transfers all about?

In order to make the entire data transfer anonymous, the MyCalorieApp server must not have any knowledge of a user’s identity. How we ensure the anonymity of the user ID is explained in detail in the previous question on data protection.

How can I change the anonymous user ID?

Once you have transferred data from one device (A) to a second device (B), both devices use the same user ID. The two devices are linked, so to speak.

If you now want to transfer the data of a third device (C) to device (B), for example, this is possible with the help of a download code. Create a data transfer on device (C) and enter the generated download code on device (B). Then download the data. This deletes the existing user ID on device (B) and replaces it with the user ID of device (C). From now on, devices (B) and (C) are linked.

Please note that this is a special case. Normally, it would be usual to use the same user ID on all three devices (A), (B) and (C). Simply create a data transfer on device (A) and enter the download code on device (B,) and then on device (C), download the data in each case, done!

When is a data transfer useful?

In general, a data transfer makes sense if you want to transfer your data from one device to another. It doesn’t matter whether it’s a one-off transfer, e.g. when switching to a new device, or whether you generally use two devices in parallel in everyday life, e.g. a tablet and a smartphone.

However, a data transfer is unsuitable for use as a backup. As the lifespan of a data transfer is only 1 hour, it is not a solution for emergencies.

Can I also transfer data to another app?

No, a data transfer is always linked to an app. It is not possible to transfer data between different apps, e.g. from “Purine!” to “Calories!” or “MyCalorieApp”.

What options are there for transferring data? (Calories! and Purine!)

1. Data Transfer

  • Top left menu, Settings, Data Transfer
  • All data
  • MyCalorieApp server
  • Lifetime: 1 hour
  • Max. 5 transfers in 24 hours (Purine! and Pro Platinum version of Calories!) or 2 transfers per year (free version of Calories!)
  • Advantages: Easy transfer, pairing of devices, 2 or more devices possible
  • Disadvantages: No mixing of data statuses, no unlimited storage, no automatic synchronisation

2. Backup

  • Top left menu, Settings, Backup
  • All data
  • Google Drive or locally on the device, a manual transfer of the backup file is possible
  • Lifetime: unlimited
  • Unlimited number of backups
  • Advantages: Full control, backup with unlimited lifetime, 2 or more devices possible
  • Disadvantages: More complex than data transfer, no mixing of data states, manual transfer requires Android knowledge, and no automatic synchronization

3. QR Code

  • Open your user-defined food or recipe in edit mode, top right menu, Share
  • 1 food or 1 recipe
  • QR code
  • Lifetime: as long as the QR code is displayed
  • An unlimited number of QR codes
  • Advantages: Food and recipes can be shared with other users, e.g. within the family
  • Disadvantages: Only 1 food or recipe at a time, both devices must be in the same room, no automatic synchronization

Log-in and Server

How can I delete my own data from MyCalorieApp?

You can delete your data directly from the app: Top left menu, Settings, MyCalorieApp server, “Delete user-generated data”.

In the same screen, you can also lock your user account if needed: “Deactivate account”.

If necessary, you can irrevocably delete your user account and all associated data: “Delete user account”.

Why are Facebook and Amazon logins no longer supported?

We no longer want to cooperate with Facebook. Facebook has been in the headlines since 2018: Cambridge Analytica, influencing voters through targeted political ads, knowingly allowing lies and untruths to be spread. Facebook has a huge ethical problem.

Our apps have not shown any Facebook ads for a while. Now we’re going to take the next step and no longer support logging in with Facebook. From March 1st, 2021, it will no longer be possible to log into MyCalorieApp with Facebook.

We will also retire our Facebook page in March 2021 and our X/Twitter page in June 2024. Follow us on Bluesky for the latest news: https://bsky.app/profile/digitalcure.bsky.social

The registration with Amazon was intended for the Amazon App Shop. MyCalorieApp should also be distributed for Amazon devices, and therefore, an Amazon login is mandatory. Unfortunately, it was never published on Amazon. Very few users currently use Amazon to sign in, which is why we decided to no longer support Amazon. From March 1st, 2021, it will no longer be possible to log into MyCalorieApp with Amazon.

Will my data be retained when the Facebook / Amazon log-in is retired?

Yes, basically no data is deleted when the Facebook and Amazon login is no longer available. The previous storage periods continue to apply. However, we recommend that you migrate your data to a new user account as soon as possible.

How can I switch from Facebook / Amazon to a different login without losing my data?

You can easily migrate your data yourself up to and including February 28th, 2021. Please log in to MyCalorieApp with your Facebook or Amazon account. On the dashboard, you will find a new tile and a button to start the account migration. You can use an existing user account or create a new one. After the successful login, your data will be migrated automatically.

After the migration, your previous user account will be automatically deactivated in order to avoid accidental login. The app returns to the login screen and you can now log in with your new user account.

What happens to my Facebook / Amazon log-in after the change date has expired?

From March 1st, 2021, it will no longer be possible to log in with a Facebook or Amazon account, i.e. You can no longer migrate your data yourself. Please contact the support team and provide us with the email addresses of the two user accounts (retired account + new account). We will do our best to migrate your data as soon as possible.

Network and Battery Usage

Why does the app consume a part of my monthly network traffic limit? (Calories!)

The network traffic is caused by ads and the synchronisation with the associated app store. We have to use ads to make this app freely available to all customers, and we ask for your understanding. Since October 2013, there’s an ad-free version – please open the menu at the upper left corner and choose Shop.

Why does the app consume X per cent of my battery?

The biggest energy consumer is the screen of the device. But without the screen, the device is unusable, sadly… The app itself doesn’t do background activities, when it is invisible to the user – no calculations, no downloads, etc. If you’re using the app very intensively, the battery consumption rises. Just like every other app would do, too.

Can you please tell me something about your plans for the next versions of the app? When will feature XYZ be released?

Please contact us via email if you have any questions concerning new features.

How long does the app still support my Android version?

In spring 2019, we discontinued the support for Android 4.x. Starting from summer 2020, we will discontinue the support of another Android version year by year. Our goal is to actively support every Android version for about 6 years.

The minimum requirements in detail:
from August 2022: Oreo, Android 8.0
from August 2023: Pie, Android 9.0
from August 2024: (no change)
from August 2025: Android 10
from August 2026: Android 11
from August 2027: Android 12
from August 2028: Android 13
etc.

Important: Even if the Android version of your device is no longer actively supported by us, you can continue to use the app as usual. You just don’t get any new updates anymore. Apart from that, nothing will change for you.

I have installed the free trial version of “Purin!”, but I no longer want to use it after the trial period. Do I have to cancel my subscription?

No. By installing the free trial version, you are, of course, not entering into any obligation. After the trial period has expired, the app functions can no longer be used, and you will be automatically redirected to the store.

You will only be charged if you actively start a subscription or purchase the lifetime version. As long as you do not start a purchase or subscription yourself, there are no obligations. Consequently, you cannot cancel a subscription.

Which features have been moved to the free version or the Pro version? (Calories! version 9.1)

Since the apps “Calories!” and “MyCalorieApp” are getting closer and closer together, we would also like to adjust the availability of the individual functions in the free version and in the Pro version. This should make it easier for users to switch between the apps, and at the same time, it will reduce the maintenance effort at the source code level. Unfortunately, it’s unavoidable that some functions that were previously free of cost are now part of the Pro version. In return, however, other functions are no longer subject to a charge and are therefore available to all users.

The following features of “Calories!” are usable free of charge since version 9.1:

  • Current value of fructose,
  • Current value of vitamin D,
  • Current value and daily value of vitamin B3,
  • Current value of vitamin B12,
  • Current value and daily value of vitamin K,
  • Preview when adding a consumption for fructose, vitamin D, vitamin B3, vitamin B12, vitamin K,
  • Preview of foods and recipes for fructose, vitamin D, vitamin B3, vitamin B12, and vitamin K,
  • Express input for consumption,
  • Express input for trainings,
  • Extracting recipes in “My Day”.

The following features of “Calories!” are in the Pro or Pro Platinum version starting with version 9.1:

  • Previous and next period in the analysis (Pro) (a single day in the free version),
  • Free choice of start and end date for periods in the analysis (Pro),
  • Select any period in the analysis (Pro),
  • Evaluate meals (Pro Platinum),
  • Unlimited number of recipes (Pro) (25 recipes in free version).
  • Individual daily values (Pro).

If you have any questions or suggestions, please contact the support team.

Is the app available as an open source project, and how can I create a fork of it?

Our apps aren’t open source, and that’s why you cannot create a fork.
