Built a free offline workout tracker because I was tired of subscriptions
A few months ago I got fed up with my workout tracker.
Every app I tried wanted an account, a subscription, cloud sync, AI coaching, social features... I just wanted to log my lifts.
So I started building my own.
It was originally just for me, but it slowly turned into something much bigger than I expected. I ended up spending evenings and weekends adding all the things I wished other apps had.
Current features:
Completely offline (no account required)
Rest timers
Automatic warm-up sets
PR detection
Volume tracking and analytics
Bodyweight and cardio logging
500+ built-in exercises
Custom exercises
ExerciseDB cloud search for even more exercises
Export your data whenever you want
The biggest challenge wasn't actually building features, it was getting everything polished. One bug with Android back navigation took multiple attempts to fix because every change seemed to break something else. AI helped massively, but it also had a habit of confidently "fixing" one issue by introducing two new ones.
I've just pushed the first production release to the Play Store. It's a strange feeling seeing something you built sitting there for anyone to download.
I'd genuinely appreciate any feedback from people who lift regularly. I'm still actively improving it, so feature requests (or brutal honesty) are welcome.
