Who is the Polar A370 fitness tracker for?
With Polar A370 you can track your daily activity and sleep as well as your training sessions to get a complete picture of your overall fitness based on the intersection of activity, rest and recovery. It’s for anyone looking for a sleek, light-weight and waterproof fitness tracker. To complement your style, this take-it-anywhere fitness tracker comes in six different colors.
What’s new in Polar A370?
Polar A370 adds continuous heart rate tracking and advanced Polar Sleep Plus analytics to the mix. Furthermore, GPS via mobile enables you to track distance, speed and route when Polar A370 is connected to the Polar Flow app on your phone and you’re doing outdoor sports. You’ll also need to keep your phone with you while you train for the GPS via mobile to work.
Polar A370 can be used as a heart rate sensor with any other compatible Bluetooth device or mobile app. For example, you can use the Polar A370 as a heart rate sensor with a bike computer, such as the Polar M460.
The new features have been designed and optimized for the new Polar A370. Because of service and software restrictions, we’re unable to bring them to its predecessor: Polar A360.
Comprehensive activity tracking with Polar A370
One of the most exciting new features is the introduction of continuous heart rate tracking. Polar A370 measures your heart rate automatically throughout the day and night which gives you two main benefits:
- Comprehensive daily activity tracking
- Heart rate highs and lows for spotting trends in your heart rate
Thanks to the introduction of continuous heart rate, activity tracking on Polar A370 is based both on your wrist movements as well as your heart rate. Polar A370 combines this data to provide immediate guidance toward reaching your activity goals. A more detailed daily overview and insightful fitness guidance is available in the Polar Flow app.
If you’ve used our products before, you may even notice that you reach your daily activity goal faster, due to a new level of precision of our new fusion of heart rate and activity algorithm.
“The utility of traditional heart rate monitors has been limited to workout sessions only; but what about the other 23 hours of the day? Understanding those hours – whether spent training, resting or doing light activity – is crucial to achieving fitness goals,” says Tom Fowler, President of Polar U.S.A.
“Polar developed continuous heart rate to fill that critical gap. Now, we’re enabling users to take charge of their fitness with a 24/7 perspective on their heart rate profile, activity levels and even rest and recovery. This is a game-changer for athletes of all levels from beginner to pro.”

Advanced sleep tracking with Polar Sleep Plus
Another exciting evolution is Polar Sleep Plus™, an intelligent sleep system with a smart algorithm that tra
cks the timing, amount and quality of your sleep with the 3D accelerometer within Polar A370.
Our proprietary Polar Sleep Plus algorithm uses polysomnography as a reference measurement, the golden standard to assess sleep in science and medicine. Designed to provide accuracy in sleep detection at the same level of the polysomnography standard, Polar A370 provides precise measurements that offer increased accuracy and guidance.
Polar Sleep Plus is designed for people looking to find a balance between activity and rest, which includes learning healthy sleep patterns.
Polar A370 tracks a variety of different metrics, including:
- Total duration of sleep
- Actual sleep time
- When you fall asleep and wake up
- Interruptions that occur during sleep
Based on these metrics, Polar Sleep Plus can provide you with a continuity score on a scale of 1–5 to show how continuous your sleep was. You can also rate your sleep the next morning. By following your sleep routines, amount and quality of sleep over time you can adjust your sleep schedule in order to reach your goals.
