A Deep Dive Into The Polar H10

The Polar H10 Bluetooth heart rate sensor is everything the Polar H7 was … but better.

The main improvement is an internal memory that stores a single session up to 65 hours long. This means you can leave your phone or watch at home.

The H10 can also transmit heart rate data to the GoPro Hero 4 & 5 action cameras adding HR data to your videos. It also features improved heart rate accuracy and silicone nodules to prevent the belt slipping.

Before we Start …

Who really wants to wear a chest strap heart rate monitor? Not me.

I understand that for 99.999% accuracy a chest strap heart rate sensor is the most accurate, however, I’d rather have something a little more comfortable. In late 2017 Polar introduced us to a new product, the Polar OH1 (Optical Heart Rate) – an armband style HRM sensor that can be worn on the upper or lower arm.

Heart Rate is accurately acquired from the 6 x LED sensors. This heart rate data is then either BROADCAST to compatible Bluetooth devices or STORED internally for download to Polar Flow at a later time.

In this storage mode the Polar OH1 armband heart rate monitor can be used as a standalone device recording up to 200 hours of total training data.

If you simply want to record heart rate on your iOs or Android device running your favourite fitness app (Polar Beat, Endomondo, Strava, MapMyRun etc) the Polar OH1 could be just what you’ve been looking for.

It can also broadcast HR data to other compatible Bluetooth devices eg. Polar M460, POlar V800, Suunto Spartan (range) etc. Or simply strap it on your arm, turn it on, press the button twice to enter STANDALONE mode and go train.

All your heart rate data is conveniently stored for download to Polar Flow when you’ve finished….

Main Features and Functions

  • Bluetooth 4.0 (BTLE Smart)
  • Built-in memory can store ONE complete training session. HR data sampled once per second and the training session can be up to 65 hours. This data can be downloaded to Polar Beat App after training.
  • GoPro Hero 4 & 5 compatibility for streaming HR data to action video !
  • Improved electrode design with better contact to skin
  • Addition of non-slip silicone nodules to prevent belt slippage
  • Supports older Polar watches using 5kHz signal (T31 & Wearlink)
  • Easy change battery – the H10 uses a CR2025 which provides up to 400 hour heart rate recording
  • Supports popular training equipment using 5kHz signal (treadmills, steppers etc with Polar logo)
  • New algorithm makes the BEST HR sensor even BETTER
  • Transmits HR data when SWIMMING to the Polar V800 and any other Polar device supporting 5kHz (not BTLE or Polar WIND)
  • Compatible with the Polar Beat app and many other smartphone apps, eg. Strave, MapMyRide, Endomondo etc
  • Compatible with Polar Club and Polar Team solutions
  • Review summary and conclusions
  • Alternative Bluetooth HR sensors

    COMPARISON - Polar H10 vs H7

    The main differences between these two Bluetooth heart rate sensor belts are –

    • Internal Memory for 1 training session (not in H7)
    • Support for GoPro Hero Cam (not in H7)

    Internal Memory for 1 session

    This is a key feature of the Polar H10. You can train without watch or smartphone. The H10 has an internal memory for 1 training session. This session can be as long as 65 hours.

    I have quickly tested this and it works very well. The procedure is as follows (also shown in the image below)

    1. Start Polar Beat app
    2. Press top RIGHT and select “Save HR with Sensor”
    3. Once the two icons have solid BLUE lines, indicating H10 is paired and acquiring heart rate, you are ready to TRAIN
    4. At end of the session, press the RED cirlce to STOP the session
    5. Your heart rate training data is then downloaded to the Polar Beat app. It is then displayed as shown in the final two images in the sequence below.

    Video Review

    Here's a video video review, it's 9 minutes long and I try to give themost in-depth real-world feeling on how Polar H10 works. As always, unscripted so as true as it gets! 


    An interesting alternative is the Kardia Mobile by Alivecor that we recently reviewed at TheBestInTech which is an ECG unit specifically designed to spot atrial fibrillation. 


    Polar have lead the world in heart rate monitoring since 1976 for a good reason.

    Their products are exceptional quality and can be considered as the GOLD STANDARD of heart rate monitoring.

    I have always used the previous Polar H7 as my CONTROL heart rate monitor when doing comparisons with other models. This new Polar H10 is EVEN BETTER. It will be the unit I now use when testing and comparing the heart rate accuracy of other devices.

    Standout new features are the internal memory for training without your phone or watch and it’s GoPro Hero compatibility. It’s impossible to criticise the Polar H10 (other than price…) I have awarded the H10 an exemplary 5/5 star rating
