The Polar A370 is an appealing, sporty, waterproof fitness tracker that helps you stay in tune with your heart around the clock through continuous heart rate monitoring, advanced sleep tracking, and unique training features from Polar.

Discover how your heart responds to the ups and downs of your daily life. The Polar A370 wrist heart rate monitor tracks your pulse 24/7, giving you a complete overview of your daily activity. It shows you how many calories you've burned, your lowest and highest heart rates, and how your heart rate varies throughout the day.

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

When you train outdoors, the Polar A370 uses your smartphone's GPS signal to measure speed and distance and track your route. With Polar A370's Smart Notifications, you stay updated even when you don't have time to check your smartphone. You receive notifications directly on the display of your Polar A370 for incoming calls, messages, or social media updates, as well as calendar appointments.

Training is simple and enjoyable thanks to wrist heart rate monitoring. The heart rate zones help you train with the right intensity. Polar's unique, scientifically validated Smart Coaching features guide you through your workouts and provide motivating feedback.
