A dead-simple journal for bodyweight workouts.

- supporters
The problem: you did 20 push-ups in your living room. Where do you write that down? Most fitness apps want your meal plan, your sleep schedule, and your credit card. You just want to log some reps.
Kountrain: open, tap, log, done. Six bodyweight exercises out of the box (push-ups, squats, planks, burpees, pull-ups, lunges), each with a form guide. Hide the ones you skip, reorder the rest. Everything runs on-device, no account, no internet. Every workout you log is yours, export it as a spreadsheet for free, anytime.
The only paid thing is adding your own custom exercises: a single Premium purchase, paid once, yours forever. No recurring fee for a rep counter.
