It does work !

As many others have mentioned already, I downloaded the app in spite of the reviews saying that the app doesnt work.

That night I tried the app out to only discover the next morning that the watch wouldnt sync to the phone app . Needless to say, I wasnt very pleased. I then gave their trouble shooting guide a read and followed their instructions and the problem was fixed. The app is working great for me .

If you have had issues with the app I strongly recommend going through the trouble shooting guide and follow the listed steps, it will correct any issue, at least it did for me.

The only reason I am giving this app 4 starts rather than 5 is because it would have been nice to include some info within the app on how to interpolate the various charts.
