Built for the ride

Everything you need at a glance. Nothing you don't.

  • Readable in full sun

    Big, high-contrast numbers you can read with one glance, even with the screen dimmed.

  • Radar alerts

    Pair a Garmin Varia and see vehicles approaching from behind before you hear them.

  • Your sensors, your zones

    Connects to Bluetooth heart rate, speed, and cadence sensors. HR zones are set from your Apple Health data.

  • Automatic wheel sizing

    GPS calibrates your wheel so speed and distance from your sensor stay accurate.

Private by design

Your rides stay on your iPhone.

  • No account

    No sign-up, no login, no backend. Open the app and ride.

  • On-device history

    Routes, heart rate, and ride history are stored only on your phone, and nothing is sold or shared for advertising.

  • Share on your terms

    Completed rides can be saved to Apple Health, and you can export any ride as a GPX file.
