Track workouts without slowing down.
The core tracker is free: log every set, reuse your templates, and keep a clear record of your progress. Pro is there when you want more.
Exercises and templates
Pick from more than 180 built-in exercises, save up to 3 templates, and create up to 10 custom exercises. Pro removes both limits.

Keep your workout and rest timer on the Lock Screen, and log sets or adjust your rest without opening the app.
Apple Watch companion
Start workouts, log sets, follow rest timers, and view live heart rate from your wrist.

Workout data stays on your devices unless you choose to sync it. Use iCloud Sync for free, or KILO Sync with Pro.
A recap before you’ve left the gym.
After a session, choose Generate to create a short recap with KILO Pro, built from the workout you have just logged.
- Based on your session
It only works from what you logged: your sets, your time, your volume, the muscles you worked, your notes, and any records you set.
- Powered by Private Cloud Compute
When you choose Generate, workout details are sent to Apple’s servers for processing. An internet connection is required.
- One short paragraph
See how the session went at a glance, without reading back through every set.
Needs KILO Pro, a supported iPhone running iOS 27 or later with Apple Intelligence switched on, and an internet connection.
