Challenges
Results
Initially, the app was to be implemented for the iOS and Android platforms. A short time later, a WatchOS app was also developed to make it even easier for users to manage their drinking habits.
The app calculates the individual daily requirement based on health and fitness data.


Notifications
Push notifications remind users to drink and motivate them to reach their personal goal. With the Apple Watch, the current drinking level can be viewed at any time.
Adding drinks
Users can choose from over 12 drink categories. Frequently added drinks can also be conveniently selected from the home screen or on the Apple Watch.


Statistics
The app calculates the individual daily requirement based on health and fitness data. Gender, age, weight, and height, as well as daily data such as weather, steps, and activities, influence the drinking target. The exact calculation and its medical correctness were ensured in close coordination with the Cologne Sports University as well as networking with corresponding interfaces such as Apple Health.
