ontrack apps

Small tools for runners.

Free, browser-based tools from ontrack. No account, no install, nothing recorded — they run entirely on your device.

Your footprints

Drop your Garmin or Strava export and watch a decade of your runs draw itself as a living point cloud — parsed and rendered entirely in your browser, nothing uploaded.

Best on desktop. Free for ontrack runners — your code is in the app under Settings → Your footprints.

Live heart rate

Connect a Bluetooth heart rate monitor — a Garmin strap or a watch in broadcast mode — and watch your heart beat live, departure-board style. Nothing is recorded.

Works in Chrome and Edge on desktop and Android.
