Polar H7 heart rate sensor

Phone not included

Polar H7 Bluetooth Smart Heart Rate Sensor

Understand your workout better and get more effective results with the Polar H7 Bluetooth Smart heart rate sensor. This triple-action heart rate sensor provides your real-time heart rate to mobile training apps, many Polar products and compatible gym equipment.

Here's how it works
board walkers

The Polar H7 heart rate sensor is compatible with Bluetooth Smart ready devices that support heart rate service (see compatibility list below). A separate smartphone app (such as the free Polar Beat) is required to view your heart rate data. When you use the H7 for the first time, you will need to pair it with your device. After that, wrap the H7 heart rate sensor around your chest and begin your workout.

Take it to the gym

Gym equipment with Polar heart rate technology inside will sync with the H7 heart rate sensor. This means you will get hands-free heart rate measurement. Plus, the H7 heart rate sensor picks up your heart rate only and not other heart rate monitors nearby.


• Compatible with the following Apple devices: iPhone 4S, iPhone 5/5C/5S, iPod touch (5th generation), iPad (3rd & 4th generation), iPad mini, iPod nano (7th generation)

• Compatible with the following Android devices with Android 4.3 or later: Samsung Galaxy S3, Samsung Galaxy S4, Samsung Galaxy Note II, Samsung Galaxy Note 3, LG Nexus 5

• Also works with Polar heart rate monitors using 5kHz transmission (also called GymLink). Compatible products include, but are not limited to: FT1, FT2, FT4, FT7, FT40, FT60, FT80, RS100, RS300X, RS400, RCX5. The H7 will also transfer heart rate information while swimming with these products.

Set Up Tips

Setup Tips

Keep these tips handy during your initial set up.

  1. Check that your device supports Bluetooth 4.0 (Bluetooth Smart) and its standardised heart rate service. The Polar H7 is not compatible with earlier Bluetooth versions.

  2. Check that you have paired the heart rate sensor with the application. If pairing does not work, ensure Bluetooth on the receiving device is enabled. When pairing, make sure you are far (10m) from other Bluetooth Smart heart rate sensor users. If your receiving device has a Bluetooth devices list, you can check if the sensor is paired. Polar H7 along with its ID number is listed when the sensor is paired. The ID number is printed on the back of the sensor. (Note: iPhone 4S and iPhone 5 do not show Polar H7 in the Bluetooth devices list.)

  3. Check that you are wearing the heart rate sensor correctly. Be sure to moisten the electrode areas of the strap with water, attach the connector to the strap and wrap the strap around your chest. Adjust the strap length to fit snug, but comfortable. Check that the moist electrode areas are firmly against your skin and that the Polar logo of the connector is in the upright position.

  4. Check that the device is positioned correctly. Keep the receiving device in front of you to ensure sufficient transmission range.

When this is working, it's great & does everything that I could want; especially when linked to the edmondo app. However, & it's a BIG "however" is constantly losing its power. The monitor plays dead & nothing, including changing the battery, revives it. An internet search showed this to be a common issue & it's resolved by opening up the battery enclosure & bridging the metal connectors with a paper clip!! It then miraculously comes back to life. I cannot tell you how annoying this is as it can be perfectly ok before you leave the house then, 5 minutes later, at the gym (& without your paper clip!!) it's dead so no recording of results....Grrrrr.

Even though my FT80 came with a HRM strap, I really wanted to synchronise in real-time my Polar data with the apps I was running on my iPhone; the Polar H7 allows you to do exactly this.

Setting it up was a snap with the watch finding it right away and the iPhone apps just needing to be connected individually. I should point out though that at first I thought it was faulty at the unit does not show up in the Bluetooth list as I expected, but is connected though each apps settings screen (the user guide makes no mention of how the device works with an iPhone.)

Once you set up the device and set off, you see your heart rate accurately displayed not only on your watch, but on the app too; something I've found to be *highly* motivating when comparing work-out data as you can easily see your fitness and endurance levels improving with actual data, not just a 'feeling'.

In summary then, a superb product which (for me at least) has really helped me track and improve my fitness, but make sure you use the latest version of your apps for it to work on the iPhone 5.

*update* Since posting this, many of the apps have been updated for the iPhone 5. I can confim that the H7 now works perfectly with the latest versions of the most popular fitness apps (Runkeeper, Endomondo etc.).

*2014 update* Happy to report that the same H7 that I bought a couple of years ago is still working perfectly and still using the original batteries. It also works perfectly with the new Polar Loop.

I am very impressed with this little gadget. At around £50, it isn't the cheapest model on the market but it does have lots of interoperability with various apps for iPhones as well as Android systems. I have used this with my iPhone 4S and my Nexus 7 (both via bluetooth) and find it to to be accurate.

I tend to use this heart rate monitor at the gym, connected via bluetooth to my iPhone, so that I can track stats using Endomondo, but as well as broadcasting the heart rate to my iPhone over bluetooth, it also broadcasts the rate over the traditional radio frequency so that it is displayed on the machines at the gym. My gym uses Matrix Fitness equipment.

So, how does it work? Well - you button the device onto the strap, add some water to the strap and put it on your chest. Then you go to your phone app and try to pair the monitor with the app. I found that I couldn't connect to the device from my phone using the traditional bluetooth menus; I had to go through the app and click "Pair heart monitor" (or similar text). This was a little unusual so perhaps it is a feature of the new Bluetooth 4.0 BLE (Bluetooth Low Energy) - apparently this means it will sap less energy from your phone - this can only be a good thing. With regard the treadmills, static bikes and cross trainers, among other machines at the gym, I simply had to walk near them and my heart rate appeared on the screen. In fact, my heart rate was being broadcast to my machine as well as the machines either side of me - I found this a little quirky, but it didn't bother me. I'm not sure how more than one of these in close proximity would interact with the fitness machines; it could lead to false readings. However, I have yet to experience this.

I have used this bluetooth heart rate monitor for the last 3 weeks or so, I have it connected to 2 apps, the polar mobile app and 'map my fitness' on my android phone (Sony Xperia Z1 Compact). On 2 occasions I have had to remove the flat coin battery to reset the unit as it wasn't displaying my heart rate in either app. Once this is done it is fairly quick to re-establish communication however not something that was ever necessary or even possible in my old coded heart rate monitor, so a little annoying especially when you are all ready for your workout and nothing happens. That's were the first star is docked. Hopefully this is something that will not happen too regularly but if it does I may need to look at a warranty replacement.

This leads to the next snag and the reason for the three start, compared to the old style heart rate monitor strap the fastening mechanism is a nightmare and very fiddly, it takes a while to get used to due to the fact that it is a very thin loop of material that you pass a hook through to secure the strap. Why polar could not have used there original design I'll never know, this makes the strap seem cheap and poor quality. As the HR monitor is detachable from the strap this may be a ploy to get you to buy s deluxe strap as an aftermarket item, I haven't seen these for sale yet but watch this space!

All in all though I much prefer the new system and the amount of data that is now processable on a mobile phone app compared to reading it on a watch screen like I have done for years. This option is a lot more affordable than purchasing a new watch (which was what I was looking to do when I purchased this) as most people have a modern mobile phone which supports bluetooth LE (4.0) and it is normally something that is carried on a workout.
