Heart rate in, estimated watts out

WattBeat turns the heart rate from your Apple Watch into an estimated cycling power figure and broadcasts it from your iPhone over Bluetooth, so that Zwift, ROUVY and other apps see it as a power meter and a heart rate monitor. It is not a smart trainer: it cannot change resistance.

Getting started

  1. Install WattBeat on the iPhone; the watch app installs with it. Open both once and allow Health access on the watch and Bluetooth on the iPhone.
  2. Open WattBeat on the watch. It starts an indoor cycling workout on its own and shows your heart rate within a few seconds.
  3. Open WattBeat on the iPhone and leave it on screen. The top of the Metrics tab shows the name to look for, “WattBeat” followed by four digits.
  4. In your cycling app, pair that name as the power source and as the heart rate monitor. Once paired, you can lock the phone.
  5. Set your heart rate range and maximum watts on the Controls page of either app. Watts are zero at the bottom of the range and reach your maximum at the top. Changes on one device follow on the other.
  6. When you are done, press Stop on the page to the left of the watch’s metrics, or the Stop button on the iPhone. Both devices stop, and the workout is saved to Apple Health.

When something does not work

The cycling app cannot find WattBeat

Watts stay at zero

Numbers differ from my cycling app

WattBeat shows the heart rate and estimated watts it is sending. A cycling app may smooth or average them, and it computes its own totals, so small differences are normal. A watts figure that lags a few seconds behind heart rate is also normal.

Workouts in Apple Health

WattBeat saves an indoor cycling workout when you press Stop after a ride of at least a minute. Shorter sessions are discarded so that opening the app for a look leaves nothing behind. If you quit the watch app from the app switcher instead of pressing Stop, watchOS ends and saves the workout itself.

The watch keeps coming back to the front

watchOS returns to an app that has a workout running whenever you raise your wrist. Press Stop on the page left of the metrics when you finish riding.

Purchases and refunds

WattBeat is sold through the App Store, so purchases, receipts and refunds are handled by Apple. To request a refund, use Apple’s Report a Problem page. We cannot issue refunds ourselves.

Privacy

Nothing leaves your devices except the Bluetooth broadcast to the app you pair. The privacy policy has the details.
