When starting the tracker function in Windy Maps, it will start tracking right away, before it has achieved my exact GPS position. Thus, after some seconds, as my position is more precisely determined, a considerable distance may be added to my track, without me taking a single step.
Another thing, to start the tracker, you first have to tap the 'walking feet', then in the next screen, tap again to start. Couldn't one (the first) tap be enough to activate this function?
