This app gave me great experience building a complex backend. I had never managed so much data in a single project before, so building all the features above was quite an accomplishment.
The bulk of the backend is built on a list of all workouts, a list of all exercises, a class for each workout, and a class for each exercise. The workout class must keep track of all exercises in the workout. The exercise class is the most complex: it must keep track of the number of sets and reps completed for that exercise for each workout session. It must also allow for future customization (like adding or reordering exercises), while still storing previous workout data. Imagine Workout A originally consists of squats and deadlifts, and you complete that once and later add bench press to the workout. The workout history screen must show Workout A in both states, with two and three exercises. This was one of the most difficult items to implement.
Data is stored locally using Hive NoSQL.
