Since a couple of weeks, the iPhone app sometimes shows very strange step results.
e.g
As you can see, there are three periods where the app indicates more than 1000 steps, however, the total steps is only 2029.
Yesterday, I've had even 12660 steps between 9 and 10, with a total of only 3934 steps.
Does somebody has the same problem?
And, when you have solved it, how did you do this?
