Is Kiiro free?

Yes. Kiiro is free to download and free to use. There is no subscription, no trial that runs out, and nothing to buy in the app today.

What is included

Everything Kiiro does today:

Training loadAcute load, fitness level, load balance and your status, with weekly and monthly trends
Heart rate zonesTime in zones for every workout, intensity, zone trends, automatic or custom zones
Route comparisonAutomatic route matching, every run on a route side by side, personal bests
VO2 max trendsPlus resting heart rate, HRV, cadence, ground contact time, vertical oscillation and power
Every workoutMaps, splits, charts, heart rate recovery
The restGoals, streaks, full training history, written insights, friends

Many training apps keep training load and deeper analysis behind a subscription. In Kiiro they are part of the free app.

Will it stay free?

The core will stay free. We are a small team building something we want to use ourselves. Premium features are planned for later, and they will be additions, not things taken away from what you have now.

What you need

  • An iPhone with iOS 18 or later.
  • Workouts in Apple Health, usually recorded with an Apple Watch. Any model works.
  • No extra hardware, and no manual uploads. Connect Apple Health and your existing workouts sync automatically.

What about my data?

Kiiro reads your workouts from Apple Health only with your permission, and you can withdraw it or delete your data at any time. The privacy policy explains exactly what is stored, and about Kiiro has the short version.

Free on the App Store. Syncs with Apple Health in seconds.
