I installed this app to motivate myself to be more active. Apparently for every 1000 steps you get one coin. Yesterday I walked at least 3 km; the app initially said it was more than 6000 steps. After a while it dropped to 4000. Then today I checked; it became 2000 steps?! No way it can be 2000 steps. The app gave me almost 2 coins for what was supposed to be 4000 steps. You have to walk approx 20k steps to get any money, which is totally ok. But its not counting the steps correctly.
