This app allows you to track repetitions (reps) for your fitness excercises, like push-up's, pull-up's, or crunches. After an initial test, the app allows you to track your progress, and will increase the number of reps whenever you manage to finish your set.
With this app you can tackle challenges like "100 push-ups", "50 pull-ups" or "200 crunches". This app is fully open-source, won't show any ads, doesn't require permissions, and all progress data will remain on your device.
