Life on the pulse

Your ultimate training buddy and keen supporter of an active lifestyle outside the gym too, Polar A370 helps you train at the right intensity and reminds you to get up and move if you stay put for too long.

Get to know your heart

Tracking your activity is more than just counting steps. Polar A370’s wrist-based heart rate monitor tracks your heart rate 24/7, giving you a more accurate look at your daily activity and calories burned.

Sleep tight with Polar Sleep Plus™

The key to reaching any fitness goal is to exercise at the right intensity. Polar’s advanced Sleep Plus sleep analysis makes you an expert on your own sleep and helps you towards a more balanced lifestyle.

GPS via phone

The Polar A370 features Polar’s advanced Sleep Plus system, which automatically tracks the timing, amount and quality of your sleep and detects any interruptions.

Speed and distance from wrist

When you run on the treadmill, Polar A370 tracks your speed and distance from your wrist movements. It does that outdoors as well so you don't need to carry your phone with you on your runs.

Get connected

When you don’t have time to check your phone, Polar A370’s phone notifications keep you in the loop.
