What mobile phone should I use?

  • First check from your mobile phone manual that it supports Bluetooth 2.0.

  • Then go to the application page (see above) to see if your mobile phone model is supported for the application. The applications listed above might work on different mobile operating systems (e.g. Android, Symbian). If your mobile phone is not supported for one application, have a look if you could find it supported for another.

  • If you use an Android phone, please check the phone's Kernel version. This is done from Settings - About phone (- Software information) - Kernel version. We do not recommend this product for Kernel versions or 3.0.8. because they seem to use up more power communicating over bluetooth.

If you are an Android phone, please note that Kernel versions or 3.0.8. seem to use up more power communicating over bluetooth connection than other kernel versions.
Polar heart rate sensor is not compatible with Apple iPhone and Windows Phone even if you can run an above application on it.
