About Reps: Gym Workout Log
Reps: Gym Workout Log (repsworkout.com) is a gym workout log for iPhone and Android, made by Szymon Łukiewicz, an independent developer in Poland. There is no company behind it: one person designs, builds and runs the apps, the sync server and the AI coach.

How Reps works
- Your log lives on your phone first. It works offline, and you don’t need an account to use it.
- An account is optional and free. It adds sync between phones and a backup, stored in the EU.
- No ads and no third-party analytics in the app.
- The AI coach is optional. It runs on Anthropic’s Claude models only when you open it, and your data is never used to train them.
- It speaks your language: English, Polish, German, Spanish, French, Italian, Portuguese and more, exercise names included.
So far
- Jul 2026
- Reps 1.0 on the App Store.
- Sep 2026
