An open source hobby project I developed between 2020 and 2021 for Amazfit watches, featuring:

Repetitions counter using accelerometer data from the watch

Saved workouts database using SQLite

Exports of workouts in TCX format

This was one of my first projects, thus the code is not good or maintainable. Check out my newer projects for better examples.

In the same time, I was also a contributor of AmazMod, an open source app for the same watches. I implemented Sleep As Android integration (using heart rate and accelerometer sensors with batching) and remote camera shutter. Still, the code was not good or maintainable, my newer projects are better examples.
