Driven by goals

Push your boundaries and step out of the ordinary. In the Polar Flow service, you can set yourself targets and reach them – in all the sports you do. M400 also keeps tabs on your personal bests and lets you know when you’ve made a new record.

Training targets
Set targets in Polar Flow and sync them to your M400. It guides you through your training and lets you know when to speed up and when to take it easy.

Running Index
See how your running performance is developing. M400 counts your running index score automatically after every run based on your heart rate and the speed data collected by the built-in GPS. In order to obtain your heart rate information a Polar chest belt, like the H7, needs to be used.

Sport profiles
In Polar Flow you can create tailored views for each sport you do, and choose the data you’d like to see when you train.
