A free workout tracker. Room for every routine.

What you can use without a subscription

• Workout logging: record exercises, sets, reps and weights, with rest timers alongside the workout.
• Unlimited templates and custom exercises: save your own routines and add exercises that are missing from the library.
• Your full history and exercise charts: look back to your first workout, including history imported from another app.
• Body measurements: keep measurement entries and view their history.
• Plate and warm-up calculators: use them inside the app while you train.
• Imports and CSV export: bring a Strong or Hevy history, and export your completed Kilos workouts.
• Training with friends: join a live workout or log for a friend from your phone.

You can keep using these features without subscribing to the coach. Your training history remains available if a Kilos Pro subscription ends.

Use it for your next gym session

1. Bring your routine. Choose exercises and set up your workout. Save it as a template if you want to use it again.
2. Log what you do. Enter the weight and reps for each set. The workout keeps the set history and rest timer together.
3. Finish and review. The session stays in your history. Exercise charts let you compare your logged work over time.
4. Return to the same template. Use your previous work as context for the next session, and change the workout when your routine changes.

Workout logging works offline on your phone. Logged work syncs when your connection returns. Live workouts with other people and the AI coach need a connection.

Want to try one of the tools before installing? Open the free plate calculator or workout volume calculator in your browser. They do not need an account.

Switch without starting your log over

If you already use a workout tracker, export your history and preview it in Kilos before saving. Follow the Strong import guide or the Hevy import guide for the exact steps, unit checks and limitations.

You can export your completed workouts from Settings → Import & export → Export all workouts. That gives you a CSV for your own records or a spreadsheet.

If you share equipment with a training partner, work out together in Kilos. Each person keeps their own weights and reps, and a friend without the app can join as a guest you log for.

What Kilos Pro adds

Kilos Pro is the AI coach. Your first 5 coach questions are free per account, not per day. More questions require a subscription. Plan with AI and the coach's exercise suggestions under Machine busy also require Pro.

The coach is optional: you can build your own routine and keep logging without it. Kilos is a phone workout tracker; it does not currently offer an Apple Watch app. The app interface is in English.

For account, subscription or import questions, see Kilos support. The privacy policy explains how your training data is handled.
