Can students use their own heart rate sensors?
Students can purchase their own Polar heart rate sensors, and use them instead of school sensors. Personal sensors need to be registered into the Polar GoFit web service and Polar Flow before they are taken into use. Registering own sensors to the Polar GoFit web service is simple: just add the device ID into “Own sensor's ID” text field in student information.
On Flow-based devices the “Heart rate visible to other devices” functionality in the Polar Flow account needs to be set on in all sport profiles before the device or the sport profile can be used in the Polar GoFit application. See more information in Can Flow-based Polar devices be used with Polar GoFit? and Polar GoFit Compatible Devices.
