After running the app, the app will open up its first screen - the home screen, where the current acceleration is shown.
You can navigate to the 2nd screen - the timer screen where you can start a timer to mark the start of your run.
While the timer is running, you may walk or run or gently shake the phone/emulator to simulate a running motion. Once done, stop the timer and you can see information about the run.
Repeat this a few more times, then you may go to the 3rd screen - history page where you can see blocks of data about past runs with timestamps.
You can use the delete button to delete all the history blocks.
