Privacy Friendly Food Tracker allows you to track your daily calorie consumption.
To do this, you can enter all your consumed food and drink as well as its weight. The app will then calculate total daily caloric consumption.
The app also allows an analysis of calorie consumption over a larger timeframe such as weeks or months.

- privacy-friendly-food-tracker/app/src/main/java/org/secuso/privacyfriendlyfoodtracker/: This is where the main functionality of the app is stored. It has several subfolders, the important ones are listed below:
- /activities/: This is where all activities are stored. This is generally what you see on screen.
- /activities/adapters/: These are all adapters that are needed by several classes such as Fragments. This also contains the database façade which is used to talk to the (encrypted) database.
- /database/: This is where the database structure and the database functions are stored. The database uses Room to create an encrypted database with a key that is generated via the KeyGenerationActivity in /activities. The database uses a Data Access Object pattern to retrieve entries.
- /network/: This is the package that is used to call the Openfoodfact API. It is only used in the search function.
- /customviews/: This is for all views that are custom created for this application.
