The Polar H10 Plus is a professional heart rate sensor with outstanding accuracy. Thanks to decades of continuous improvement, the H10 Plus sensor is the most reliable performance measurement tool on the market, thanks in part to a continuous software update process.
The sensor is designed to work as a standalone device, but can also be synchronised with all other Polar equipment via BlueTooth/ANT+ connectivity.
Tracking, analysis, and interpretation of your training data is done via Polar Flow, the free app developed by Polar and available on the App Store and Play Store.
