Turn your watch into a Bluetooth Smart device providing your current heart rate.

Do you like cycling and following your heart rate on your phone or computer attached to the bike? This application makes it possible. Attach your phone or computer to your bike, start Runtastic, Zwift, or any similar application to track your activity. 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 do.

Security and privacy

This application does not broadcast anything more than a normal chest strap monitor would do. Client devices have to pair with the application to receive any data. The data is invisible for not paired devices.

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.
The only value stored is your last activity duration for your convenience by the next session.

Bluetooth protocols

Please note that 'Bluetooth' and 'Bluetooth Smart (Low Energy)' are not the same. This application supports only Bluetooth Smart (Low Energy) protocol. Heart for Bluetooth does not work with applications that support only the old classic Bluetooth or ANT+ protocols.

Known issues and troubleshooting

- GW4/GW5 stops sending data when screen is off: Connect your watch - Galaxy Wearable - Watch settings - Apps - find the app and go to "App Info - wait until "Allow background activity" activates - turn it on.
- GW4/GW5 requires re-pairing with each new session: There is no solution for this, sorry.
- Some devices won't connect, and the watch keeps showing 0/1 instead of 1/1: Make sure your watch has a stabilized Heart Rate value before you start pairing a client device. Sometimes, re-pairing or restarting your watch helps. Unfortunately, some device combinations are just incompatible and will never pair. You may try as well factory reset of the watch, some users reported success after this step.
- Some watches cause interruptions in the HR data due to battery saving restrictions: As a workaround, starting another native sport application on the watch in the background keeps the device awake and helps stabilize the connection. Heart for Bluetooth runs on top of that in parallel. Another workaround that might help is enabling the 'Always On' mode on your watch.
