​Works with Polar products
Not a fan of chest straps? Polar OH1 is a great alternative for you: it works with all Bluetooth-compatible Polar sports watches, trackers and cycling computers.

Your phone is your training buddy
Polar OH1 streams real-time heart rate to many popular fitness apps on both iOS and Android phones.
Polar OH1 is a great companion to Polar Beat, Polar’s free fitness and training app. With Polar OH1 and Polar Beat you get live heart rate data right on the screen of your phone and audio guidance to your headphones during your workout.

Use it on its own
Prefer training without a watch or phone? Polar OH1 has an internal memory that can store up to 200 hours of training data.
You can easily sync your data to Polar Flow, Polar’s free app and web service, via Bluetooth or with your computer via the USB adapter.

You choose how you wear it
You can wear Polar OH1 on both the upper arm and forearm, just the way you want. It’s easy to put on and take off anywhere, anytime.
