Description
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.

Brilliant app, will broadcast heart rate from Samsung watch to any bike computer, exactly what I was looking for. Thanks

Been using this to broadcast HR from Samsung Watch 8 to Peloton Bike. Works great. Recently switched from Garmin and surprised this functionality isn't natively supported by WearOS so having this app has proved very useful. Big thank you to the developer.

Giving 4 stars with a question. I am trying to connect my GW8Classic to the Techno gym Exite 600 treadmill. But it's not pairing with the Treadmill in any way. I tried to pair it with the Techno gym 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.

Peloton and Galaxy Watch works. Finally!!!! Please follow the instructions mentioned in the About app readme to make the app allow for the background activity. 1. Install this app, open the app on the watch and allow HR sensor activity. 2. Open wear app on the phone and open apps and this app settings and allow for the background activity. 3. open the app on the watch again and hit refresh button there. 4. open the Bluetooth setting on peloton and connect generic HR device using Bluetooth. You should be able to see the galaxy watch there. 5. one connected, allow for the passkey / etc., and then you should be able to see the HR in peloton sessions. After workout . There is a button on the watch app to close the session and stop broadcasting.

I installed the app in the Samsung Galaxy 5 watch, then went to Garmin Edge 1030 bike computer and added it to the Heart Rate Sensor. But when I click the Connect button on Garmin, it never connects. The developer is currently aware of the issue and trying to fix it

Tried this on my Wife's Gw6, and it is nice to have the watch broadcast to her wahoo bike computer. Not nice that it doesn't broadcast when the watch screen is off. Even with the display on set in configuration the watch display still goes off and cuts the signal to the bike computer. The second thebdisplay is back on I get HR data.
