Simple Workout Log
Read full descriptionHide full description
Every lifter knows the feeling: you’re in the zone, pushing hard through your sets, and the last thing you need is a confusing app slowing you down. OneRep understands that. It’s a workout log built by someone who actually lifts — no unnecessary features, no distractions, just a clean, fast way to track your workouts. You can log your sets in seconds — literally a few taps and you’re done. Between sets, you should be catching your breath, not navigating endless menus. Create your workouts exactly how you train. Whether you like to train specific muscle groups each day (like chest and triceps one day, legs the next) or prefer full-body workouts, OneRep lets you build routines your way — simple and flexible. The interface is clean and focused, so you can keep your attention where it belongs: on lifting and improving. No ads. No social feed. No clutter. Just you, your workouts, and your progress. And because gym Wi-Fi isn’t always great, OneRep works completely offline. Your data stays on your phone — private, safe, and always accessible. This is the workout log you’ve been looking for. Simple. Fast. Effective. What You Get: Log exercises quickly with just a few taps Build your own custom workout routines Create your own exercises and add them to your database Clean, distraction-free design Works 100% offline All your data stays on your device for full privacy Privacy Policy: https://hakosoltani.github.io/page/privacy.html Terms of Use: https://hakosoltani.github.io/page/terms
