This app requires the M7 motion chip and thus works on the iPhone 5S +.
Count your steps, and keep fit. Air Pedometer allows you to use your new iPhone 5S to keep track of your steps. You do not even need to be running the app for it to work.
Air Pedometer will even tell you the current Activity Type, and uses it to calculate the distance walked more accurately.
It all just works!
Note: Air Pedometer uses the iPhone 5s new M7 chip to retrieve your step count. This means that you will get the step count even for the days before you downloaded this app.
