The tracker you talk to.
Say the set between sets and it’s logged in under 350 ms, in English, Arabic or both in one sentence. No unlocking, no typing with chalk on your hands, no losing count. Say “undo” and it’s gone.
Everything you need. Nothing in your way.
Programs that run themselves
A program rotates your workouts week to week and lowers the weights on its deload weeks, automatically.
Progression built in
Set a rep range and a step on each exercise. Hit the top of the range and next time’s weight is already waiting.
Starting weights for you
New to a lift? Kooldwn suggests where to start, then learns from what you lift.
Every setup, its own history
Barbell, dumbbell, cable or machine, incline or flat: each keeps its own numbers, so your progress is never mixed up.
1,000+ exercises, and yours
A full exercise library under the names you know, plus your own custom exercises and versions.
Clean, modern, calm
Big type, clear numbers and five themes. Readable from arm’s length, with nothing on screen you don’t need.
Built for the middle of a set.
One thing per screen
Big type, numbers first, and nothing you need in the corners. You can read it from the bench without picking the phone up.
One thumb, sweaty hands
The main button sits at the bottom within reach, and nothing you tap is smaller than 48 dp.
Drag, don’t dig
Hold an exercise and drag it to reorder your workout. Pull a sheet down to close it.
Five full themes
Dark, Sand, Ink, Rose and White change the whole screen, text and buttons together, not just an accent.
Calm motion
Quick, quiet transitions, and every animation stops when your phone asks for reduced motion.
