trace for your
iPhone.

The native app is available on the App Store: readiness when you wake up, the plan before you head out, the debrief right after the session.

On Android? Android beta available on request.

How to get started

1

Get the app

Download trace from the App Store onto your iPhone.

2

Sign in

Sign in with your trace account or create one right in the app.

3

Connect your devices

Connect Wahoo, Polar, Hammerhead, Suunto, intervals.icu or Apple Health – your activities then land in trace automatically.

What the app does

  • Readiness in the morning: sleep, HRV and resting heart rate become one number and a clear call for the day.
  • Performance at a glance: critical power, W′ balance, VO₂max, durability and heat acclimatization.
  • Plan and debrief: the session before you head out, planned versus actual right after.
  • Your real data: sync with Wahoo, Polar, Hammerhead, Suunto, intervals.icu and Apple Health.
