Polar H10 & Apple Watch

Hi All,


My question has been asked by others in the past. I recently (in Feb., 2021) an Apple Watch SE together with a Polar H10 heart rate monitor. I’ve noticed that the Polar H10 frequently disconnects from the Watch (E.g., in settings > Bluetooth > Health Devices, the Polar H10 is listed as “not connected” despite the fact that, just moments before, I had established a connection. When this happens, I reconnect the Polar H10 only to find, moments later, that it is once again disconnected). This has become really irritating considering how expensive these devices are.


Ive tried all of the fixes listed in other discussions on both Apple’s and Polar’s websites, including: disconnecting the Polar H10 from both the Watch and iPhone, turning off the Watch and iPhone, then turning them back on to reconnect the H10; resetting the H10’s factory settings; and even connecting the H10 to the Watch, only. So far, no luck.


Any thoughts on why this happens? Is this a problem with other Bluetooth, chest-strap heart rate monitors; or is it unique to the Apple/Polar system? Should I just return the H10 and get a different chest strap monitor?


So annoying!


Thank you for any suggestions.

Apple Watch SE, watchOS 7

Hi there, Rpm2109,


Thank you for visiting the Apple Support Communities to get help with your Polar H10 third party heart rate monitor. We are happy to provide some general information.


According to Polar, the H10 heart rate monitor is compatible with iOS devices and Android smartphones: Compatibility of Polar H6 / H7 / H10 / OH1 Heart Rate Sensor | Polar USA. While Apple Watch is not listed as a compatible device, Polar also indicates there are compatible apps:


  • Polar Beat
  • Endomondo
  • Cardio Mapper
  • Runtastic
  • iSmooth Run


We would suggest checking to see if any of these apps have a companion app for the Apple Watch, and also making sure any apps you do use, as well as all device software and firmware, is up to date:


Update apps or use automatic downloads - Apple Support


Update your iPhone, iPad, or iPod touch - Apple Support


Update your Apple Watch - Apple Support
