Polar H10 Heart Rate Monitor – ANT Plus, Bluetooth - Waterproof HR Sensor with Chest Strap - Built-in memory, Software updates

****Review update**** I originally gave this product 3 stars - I was having mixed results with it. I assumed that this HRM was not able to maintain and record bluetooth and 5Ghz "gymlink" connections at the same time. I would switch the app on (polar or wazoo) in my gym. The PRECOR gym kit would show my HR, but when I checked the app, it showed significant drop outs.I RESOLVED this. It transpired that this was a power management issue on my phone, if I was using Spotify/Netflix at the same time, my phone was not running HR tracker apps in the background. My phone is a Huawei P30 Pro - I went to settings>Battery>App Launch and turned off "Manage Automatically" for each fitness app. Now it appears to operate flawlessly. Both for CV and resistance workout. Now - I give this 5 STARSThe Polar H10 features a suite of connectivity options as follows;- ANT+ - which is a Garmin product, and I've yet to find a use for it. I own no compatible equipment.- Bluetooth - great - can support 2 devices simultaneously.- 5ghz "gymlink" - which can connect to some gym equipment eg. PrecorIn the Polar app you can switch each of these off - I guess this would save power. I cant comment on battery life - not used it for long enough but polar app shows it as "FULL" after 8-10 hours training.The strap is not one of the generic ones, has a plastic clip to connect it together, which I hope will hold up. The cheaper ones have a metal clip.The Polar app is more than sufficient for me - provides a number of profiles for different activities. And a good HR readout is provided at the end, and you can easily see the HR zones as you train. Ive also tried it with Strava, MapMyRun, and Wazoo. All with good results.I cant comment on water resistance - others have commented on this, but I do not swim with this on.

The item arrived in a nice efficient package and was easily unpacked. Adjusting the strap is very straightforward and, once suitably modified, the strap is comfortable to wear after the initial shock of the cool pads passes.I found pairing the device to both the polar apps and the QZ app I use for my spin bike very straightforward and have had no issues with the device being automatically picked up on subsequent workouts.I bought this primarily for the reliability of the monitoring and open nature of conenction (i.e. being able to easily pair it to third party apps/devices) and I'm happy this has lived up to the promise on both counts. The monitoring element is more accurate than the optical monitor I had in my Pixel watch so I'm happy that my workouts are now being more accurately tracked and heart zone based training is more easily tracked now.The Polar apps themselves seem a bit rudimentary but, as noted, you don't have to use them for anything meaningful besides adjusting device settings and applying updates. That's going to be such an infrequent activity that I'm not counting it against the device.At the sale price of ~£60 this is an easy recommendation to anyone needing an open, accurate HR monitor.

Excellent device for sport, health and sleep. The device has functions of ECG capture, HRV capture, logging in the internal memory, accelerometer measuring movement and breathing. It is comfortable to wear, battery life 400 hours.H10 is the next generation of Polar sensors, the older H... measure fewer things.On Android it works with Polar Flow, Polar Beat, Elite HRV, ECGLogger, Sleep as Android. Firmware updates are installed with Polar Beat and Flow. It connects to the phone/tablet wirelessly with Bluetooth Low Energy (BLE), also has ANT+ for the old training equipment, supports two BLE connections simultaneously.Apart from heart monitoring and counting steps in sports, one can use it to assess one's overall fitness with EliteHRV, train to breath for health with the same app, monitor sleep with a very advanced sleep app Sleep as Android.Note, on Google Android the BLE is linked to Location services, so you may want to install the above apps in a "clean" phone/tablet, not linked to one's contract or real name/email, better with an AOSP ROM. The device can be accessed from Linux.Regretfully, it doesn't measure blood oxygen saturation, which could be useful for sleep monitoring (making counting breathing events more accurate), Wim Hof breathing method and freediving training -- get a separate sensor for this.Made in Malaysia, developed and sold by Polar in Finland.

I use this for two Polar apps and EliteHRV.It fits well, certainly no worse than any other chest straps.It connects quickly when worn.I use this to monitor heart rate variability using EliteHRV and to monitor my heart rate during exercise using the Polar Flow app.It transmits data to cardio machines so I can see my heart rate on the machine display without holding the handles.For the most part it works really well; though it has dropped the most of one exercise session and has been spotty in another - I’d have been happier if the app recognised and drew my attention to it but it just carried on as if everything was fine. It’s frustrating but one session in probably one hundred so it’s nothing to dwell on.The information uploads to an accessible website so I can view the sessions on a bigger screen later on, but the site is simultaneously clunky and basic at the same time. I’d really like Polar to rework this.There’s nothing that suggests to me that the measurements are inaccurate, getting non-smoothed data from EliteHRV makes me confident that the device is very accurate.There’s room for improvement, but if I had to pick again I’d still want one and I’d choose this over any alternatives.
