Polar A370 is an attractive, sporty, waterproof fitness tracker that helps you keep your pulse racing around the clock with continuous heart rate monitoring, advanced sleep tracking and Polar's unique training features.

Learn how your heart reacts in the ups and downs of your everyday life. The Polar A370 Wrist Pulse Monitor tracks your pulse around the clock. This will give you a complete overview of your daily activity. Polar A370 shows you how many calories you burned, how high and low your heart rate was, and how your heart rate varies throughout the day.

Sleep Plus gives you valuable insights into your sleep. Time, duration and quality of your sleep are tracked and sleep interruptions are automatically detected. You can set your preferred sleep duration and rate your sleep. You will then receive feedback on your sleep. Learn more about your sleep patterns and think about what you can do to make the most of the night.

When you train outdoors, the Polar A370 uses your phone's GPS signal to measure speed and distance and track your route. Polar A370 Smart Notifications keep you up to date even when you don't have time to control your smartphone. You'll receive notifications on the display of your Polar A370 when you receive calls, messages or messages from social networks or have appointments in your calendar.

Training is easy and pleasant thanks to pulse measurement on the wrist. The heart rate zones help you to train with the right intensity. Polar's unique scientifically proven Smart Coaching features guide you through your training sessions and give you motivating feedback.
