This is a Jog-recorder.
You could log in your Google account to use it.
And every time after your jogging, you could record it in this website.
Every week and month, the recorder would send you an Email to noticefy how much length you are jogging during this time.
Or, recorder would noticefy you that you did not do any practising during this time.
Plus, you could set your Twitter Account to auto-update your jog status with that.
