How does StepsApp count my steps?

StepsApp uses your Android phone's built-in pedometer to track your steps. Just put it in your pocket and you should be fine. If you carry your phone in your handbag, backpack, in your babybuggy or put it in the car, your phone might not be able to track all of your steps correctly. Likewise when you go for a bike ride, your iPhone might misinterpret some of your pedal strokes as steps. This happens because pedometers calculate steps based on vibration patterns.
