Can I use other Polar products at the same time?
Your Polar device is compatible with Polar Flow app, it cannot be used with Polar Beat app.
Simultaneous heart rate measurement with your Polar device and Polar Beat app is not possible. If you measure heart rate using only Polar Beat, the training summary will be synchronized from Flow service to your Polar device Diary.
If you use a Polar Loop at the same time with your Polar device, the Polar Flow web service combines the data from both products and uses the highest activity data for the summary report.
If you measure heart rate using only the Polar Loop, the training summary will be synchronized from the Flow Service to your Polar device Diary.
If you use a H7 heart rate sensor, you can use your Polar device and GymLink compatible Polar training devices at the same time. For more information, see What sensors and accessories is my Polar training computer compatible with?.
