Great customer care

I originally bought this app and was very disappointed when using it with an old Polar heart rate belt. I now use it with a cardiosport Bluetooth belt from hrv fit ltd. and it does exactly what it claims to do. The customer care I received from Simon the director of this company far excelled my expectations. He is a true gentleman. Their other product the ithlete is first class. I have used it to inform my training every day for over a year now. Unusually I have had two periods of being unwell in this year and the hrv equipment predicted both before I became aware of the symptoms. HRV measurement has to take over from the tradition blood pressure and resting heart rate procedures in the future. This software coupled with the hardware are the cutting edge for anyone who cares about their fitness and well being.

I rarely write reviews but i think this is worthy of one.
I got this after first getting the excellent sister app 'ithlete'
HRM does exactly what it says, an accurate and faultless ECG heart rate monitor which uses your own chest strap. The bar graph indicator is usefull for keeping you in your intended zone, especially good at stopping you going too hard in your base period!
The email support is excellent and friendly. The only thing stopping a five star rating is lack of a chart of recorded and live readings and not recording max HR for each lap. (I understand these are due on a update)
Keep up the good work ithlete.

Unreliable, crashes often.

Ive been running a few times now using this hrm and a polar chest strap. The interface looks nice and it is user friendly but every time i use it, it crashes loosing all the data from the run. This is incredibly frustrating as you can imagine. Also the iphone needs to be held close to the strap transmitter, it looses the signal if its in your pocket. You need to press the save button at the end of your workout so if it does crash at any point its all gone. So far for me it has crashed at different times during workouts and drops back to the main desktop screen of the iphone. My polar watch that goes with the chest strap isnt as good for data but at least its reliable - the ithlete adaptor wasnt cheap either. By the time you have the app and the adaptor you could get a very good heart rate monitor system without any bugs.
