Great hr monitor, unusable app

I agree with others here- after update, the app wont sync properly, adds multiple devices, even though I only have 1 and now has lost 6 weeks of data. It was already disappointing compared to competitors app (ie fitbit) and now I dont even want to open it until its fixed. If it werent for HR, I wouldnt consider keeping this device because of the junky app. Please fix it soon and also, make the step counter : distance tracker more accurate. Consistently 10-15% off gps.
