Made by someone who actually uses it

I built GainBook for myself. I've spent years in the gym and years cycling through tracking apps, and every one of them was missing something I needed — the set types I actually use, supersets that behave, training volume counted correctly for dumbbells and single-side work, a rest timer that stays out of the way. GainBook is all of it in one app: fast, detailed and fully offline, with no cloud account.

I train with it every week, and that is why it keeps moving — whatever I find missing gets built, so expect new features regularly. If you prefer owning your data instead of storing it on someone else's server, that's exactly what GainBook is built for.
