Discover the pulse with Polar A370, the fitness tracker that keeps you on the pulse 24/7.

Get to know your heart

Learn how your heart behaves in the twists and turns of your everyday life. Polar A370’s wrist-based heart rate monitor tracks your heart rate 24/7, so you’ll get a complete overview of your daily activity. Polar A370 shows you how many calories you’ve burned, reveals your lowest and highest heart rate and shows you how your heart rate varies during the day.

When you’re working out, Polar A370’s heart rate guidance helps you train at the right intensity and drives you towards your fitness goals.


Sleep tight with Sleep Plus

Sleeping well is vitally important to your health and well-being. Polar’s new advanced Sleep Plus sleep analysis makes you an expert on your own sleep and helps you towards a more balanced lifestyle.

Sleep Plus gives you valuable insights to your sleep. It tracks the timing, amount and quality of your sleep and automatically detects when your sleep is interrupted. You can set your preferred sleep time and rate your sleep, and you’ll get sleep feedback. Learn about your sleeping patterns and think about what you can do to make the most of your night.


Get connected

Polar A370 is BFFs with your phone.

When you train outdoors, Polar A370 uses your phone’s GPS signal to track your pace and distance and to map out your route.

Polar A370’s smart notifications keep you in the loop even when you don’t have the time to check your phone. You get notifications for incoming calls, messages, social media and calendar appointments right on the screen of your Polar A370.


Keep on the move

Polar A370 is your ultimate training buddy. It makes your workouts easy and convenient with wrist-based heart rate tracking and helps you train at the right intensity with heart rate zones. Polar’s unique and scientifically validated Smart Coaching features guide you through your workouts and give you motivating feedback.

An active lifestyle is about healthy choices outside the gym as well. Polar A370 keeps you on the move in your everyday life — it gives you a daily activity goal and reminds you to get up and move if you stay still for too long.
