Smart trainer compatibility

What you need

• A bike and a compatible trainer that exposes Bluetooth FTMS for resistance control.
• The signed intervl Mac app, or a desktop browser supporting Web Bluetooth, such as Chrome or Edge on a supported operating system.
• Optional compatible Bluetooth heart-rate, power or cadence sensors. A trainer may supply several of these roles itself.

Bluetooth alone is not enough to promise control. A trainer can broadcast power without exposing a supported resistance-control service. ANT+ and proprietary-only trainer control are not supported. Check the trainer manufacturer's documentation for your model and firmware.

Which device can I use?

Mac

Use the signed Intel or Apple Silicon app from Downloads, or a supported browser.

Windows PC

Use the web app in Chrome or Edge with working Bluetooth hardware and permissions. A native Windows installer is not part of the current launch.

iPhone, iPad and Android

Check Downloads for native store availability. Browser access for planning does not imply browser trainer control; iPhone and iPad browsers do not support this trainer-control flow.

Pairing checklist

1. Power on the trainer and wake it by turning the pedals. Keep your device nearby.
2. Close any other app or device actively controlling the trainer.
3. Open intervl's pairing panel and grant the requested Bluetooth permission.
4. Choose the trainer for resistance control. Confirm power and cadence roles where the trainer supports them; add a heart-rate sensor separately if desired.
5. Pedal briefly and confirm live readings before starting the workout.

Trainer visible, but no control?

Confirm your model supports Bluetooth FTMS, rather than only power broadcasting or ANT+. Check browser Bluetooth permission and close other trainer apps. If readings are present but control is missing, send support your trainer model, device, operating system and app/browser version. Do not send passwords.

Can I use Strava, Wahoo or Garmin?

Strava and Wahoo uploads are optional. New Strava connections have limited availability during rollout. FIT and TCX exports provide a file-based option. Garmin integration is not currently available. You do not need to connect another fitness service to create and ride a workout.
