Keep it easy.
Keep it steady.

Your bike workout, one phase at a time. Connect your Polar H10 for live HR, or read HR in Polar and use the manual controls.

Workout

30-minute easy block

    If you use Polar, start a separate Indoor cycling recording before riding. Mount your phone where it is easy to read.

    Polar H10

    — bpm

    Using H10 alongside Polar

    Wear the strap and enable “2 receiving BLE devices” in Polar Beat, or “2 Bluetooth devices” in Flow’s sensor settings. Start Polar’s recording, then connect here. Keep this app visible during the ride; check that Polar continues recording on your phone.

    H10 uses an HTTPS page in Android Chrome. The downloaded file supports manual HR. No sensor readings are uploaded.

    Backups & cloud storage

    Your rides save on this device. A full JSON backup can restore your history and settings. Cloud backup is optional and uses your own S3-compatible storage.

    Credentials are saved in this browser. They are excluded from workout backups. Use a private bucket; each app needs its own backup object path.

    Cloud backup is not configured.

    Zone 2: 105–122 bpm. Working target: 110–120. These are your supplied session targets.

    Install & offline use

    When opened from an HTTPS website, use Chrome’s menu → Add to home screen / Install app. Open once online before using it offline. A downloaded HTML file also works for manual HR without a network. H10 support needs an HTTPS page in Android Chrome.

    Paused

    Skip this phase?

    Its time will be recorded, and the phase will be marked skipped. A skipped effort is not a completed effort.
