MotionMate is a very simple, lightweight and open-source step counter app for Android that tracks your daily steps and displays the results by selecting a specific day from the calendar view and presents the values in a nice weekly bar chart as well as some other statistics.

It uses the built-in step counter sensor, if it is present on the device and uses a fallback implementation based on the accelerometer sensor otherwise.

It requires no internet access and no special permissions and is completely ad-free!
