Negative step count?!

[kleinebre]

So I started the day with -8314 steps, and supposedly yesterday in 20 minutes I managed 14000 steps. Let that sink in for a moment. How on earth? Also noticed that when correcting down the step count to 2000, the graph did not follow suit. Step count displayed by the widget severely lags behind in app count (#169), surely the point of the widget is to get instant feedback without opening the app?
Observed 1700 steps today only to see it being reset to 700 again. This should not happen as it interferes with the main purpose of the app.

Overall a nice app but needs some snags working out!
