Everything you need. Nothing you don't.

Most apps make you tap through 5 screens to log a set. We made it 2.

Gym-Floor Fast

Gym-Floor Fast

Log sets between reps, not after your session. Works with sweaty hands, bad signal, and zero patience.

AI That Helps

AI That Helps

Why we built this

We got tired of workout apps that felt like tax software. Five taps to log a set. Subscriptions for basic features. Data locked behind paywalls.

OpenTrainer is the app we wanted to use. Fast, focused, and respectful of your time and data.
