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 Polar 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.
