About this app

Do you like cycling and following your heart rate on your phone or computer? This application makes it possible. Heart for Bluetooth will provide your heart rate via Bluetooth from your watch to your phone or bike computer. Until now, this was possible only with a chest strap. Save money for that extra hardware and turn your watch into a heart rate Bluetooth provider.

Installation notes:


This application works only on Wear OS devices, it cannot be installed on Android phones. Use Play Store on your Watch to install it.

How does it work?


Start Heart for Bluetooth on your watch and connect it as an external heart rate sensor to your PC, phone, or bike computer. Your watch will provide the current heart rate via a standardized Bluetooth Low Energy protocol in the same way as any other chest strap would.

Data stored


The only purpose of this application is to provide your current heart rate via Bluetooth to other sports applications of your choice.
This application does not use an internet connection, does not send any data to the cloud, does not track usage statistics, does not provide any data to the author, and does not store your heart rate on the watch.

Works with my Galaxy Watch 4 and Ride with GPS app on Android. I noticed it wasn't syncing heartrate when my watch screen was off, then I read the FAQ and saw that this is a bug specifically on the Watch 4! Great app nonetheless, but I hope it gets fixed soon! Thank you!

Giving 4 stars with a question. I am trying to connect my GW8Classic to the Technogym Exite 600 treadmill. But it's not pairing with the Treadmill in any way. I tried to pair it with the Technogym app itself. Then it finds the watch, but once it pairs the watch screen goes off and the broadcast stops. I have the always on turned on. Any ideas? I will appreciate any help.

Thank you for the feedback! I do not have the chance to debug on the GW8 device, I assume the new OS version introduced further limitations preventing background execution. Some devices can be kept active when a native sports app is running in parallel to my app, maybe this workaround could help.

Got this working with my edge 530 and Oppo watch x2 by manually connecting to the sensor after it had paired. So pair, set up fields/pages. Start a track. Stop the track. go to setting - sensors find heart rate monitor go into that and connect manually. should work from there. Connected automatically the next time.
