Log.Lift.Get stronger.

The workout tracker for people who train seriously. Log fast, see what you did last time and get a little heavier every week.

Logging

Log your sets in seconds

Weight and reps are pre-filled from your last workout. Tick the set and the rest timer starts on its own, even on your Lock Screen.

Progressive overload

Stren suggests the next weight for every set. Hit your reps and you move up. Keep progressing without doing the math.

Progress

Charts per exercise with your estimated 1RM, heaviest set and volume. PRs are detected automatically.

Exercises

For every exercise you see which muscles it trains and how to perform it, step by step.

Calculate your 1RM, build a program that fits you or set your calories for a bulk or cut.

Calculate your one-rep max and see what weight you can lift for 3, 5, 8 or 10 reps.

Pick your goal, level and training days and get a complete workout program instantly.

Your daily calorie and protein needs for building muscle, maintenance or a cut.

Is Stren free?

Yes. Logging workouts, routines and your full history are free and ad-free.

Does it work offline?

Yes. Everything is stored on your phone first. With an optional account you back up and sync between devices.

Can I bring my history from another app?

Yes. Import a CSV export from another workout app, including your history and PRs. Stren also turns it into routines automatically.

How does Stren know when I should go heavier?

Stren looks at your reps (and optionally your RPE) from last time. Hit the top of your rep range and the app suggests a heavier weight.

Free, no ads. Your previous performance next to every set and a weight suggestion for the next one.
