I installed the Google Fit app on my phone yesterday, just to play around with it and see how it compares to an old-school pedometer. It turns out the step count is pretty close– within about 5%– and it has some other cool features like average speed, history, and of course maps.
Today I walked over to a friend’s house, and the resulting map makes it look like I was in some kind of spastic drunken stupor.
I’m pretty sure that’s not the path I took, although the start and end points are accurate. Maybe my pocket blocks the GPS signal or something, I don’t know…
