Customers appreciate the accuracy and ease of use of the H7 Bluetooth Smart Heart Rate Sensor, frequently praising its Bluetooth connectivity and compatibility with various devices. While the heart rate tracking is considered effective, some users reported issues with battery life and the strap. A few also mentioned concerns about the app's reliability.
I purchased the H7 and it works like a charm every time. My iPhone app (Polar Beat) had no problems connecting to the HRM and giving an accurate BPM. The H7 HRM strap does not track mileage or calories but strictly monitors your heart rate and communicates this information to another Bluetooth device (such as your smartphone or watch) and that device passes the information to the app. In my case, my H7 connects to my iPhone and relays the HRM data to my Polar Beat app.

I bought this to track my heart rate while working out at the gym and while running on jogging trails. So far it has performed just as I'd hoped. At the gym, it automatically pairs with the equipment, allowing me to set workout goals according to my desired heart rate. While in the weight training area, the accompanying free app (Polar Beat) monitors my heart rate. While on the trails, the app gives me verbal real-time updates and it includes maps and certain other diagnostic information about my run. My other fitness apps (Nike+ Running and Strava) are both able to read the heart rate data and include it in their summaries. I had zero problems pairing the monitor to my iPhone 6. BTW, in case anyone is concerned, the strap is very comfortable and the monitor is light-weight. So much so that, upon opening for the first time, I feared it wouldn't work. My only complaint isn't with the monitor but rather with the Polar Beat app. The voice is very robotic and kind of annoying.

I bought this to keep track of workouts on a rowing machine. It pairs easily and works well with multiple IPhone apps. An added bonus is that I can walk away from my phone across the room and my heart rate still remains active on the phone app. It also works with my Polar H4 watch. Only negative is the Polar app crashes and doesn't work at all.
