Accuracy needs calibration

I like the way this app works with my iOS iPhone, except that when I thought I had walked one mile as the pedometer indicated – – when I checked it with two cars they confirmed that the pedometer was off more than 2/10 of a mile. (So I guess the good news is that I walked further than the pedometer said I walked!) This app needs an easy way to recalibrate itself!
