Fast workout logging
Track weight, reps, set types, notes, and rest timers without breaking the flow of a session.
KILO
Your personal workout tracker.
Log workouts quickly, track personal records, and see your progress clearly. KILO Pro adds Apple Watch controls, AI summaries written on your iPhone, and the long view of your training.
Track workouts without slowing down.
The core tracker is free: log every set, reuse your routines, and keep a clear record of your progress. Pro is there when you want more.
Exercises and templates
Pick from more than 170 built-in exercises, save up to 3 templates, and add up to 10 of your own. Pro removes both limits.
Progress and analytics
Look back over your history, your personal records, and how any exercise has moved over 30 or 90 days. Pro stretches that out to a year and beyond, and adds muscle breakdowns and strength goals.
Live Activities
Keep your workout and rest timer on the Lock Screen, so you can check them without opening the app. Pro lets you control them from there too.
Apple Watch companion
Start workouts, log sets, follow rest timers, and view live heart rate from your wrist.
Private by default
Workout data stays on your devices unless you choose to sync it. Use iCloud Sync for free, or KILO Sync with Pro.
The end of a session, already explained.
Finish a session and KILO Pro writes you a short recap of it, built from the workout you have just logged.
- 01Based 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.
- 02Written on your iPhone
Apple Intelligence writes it on the device itself. Your training is never sent to us to do it.
- 03One short paragraph
See how the session went at a glance, without reading back through every set.
Needs KILO Pro and an iPhone with Apple Intelligence switched on.
