I tried a few a while back, and my cheap smartphone bombed out with them. The phone was too slow for Strava and I forget why I didn't use Map My Ride.
Anyway, I got an Iphone 4S for Christmas and just bought an Otterbox case that I can attach to my bike.
So I could use it as a bike computer, right?
I went for a walk using Map My Ride last week. The problem was that the path it showed me going was basically where I went, but it looked like I was drunk when I was walking. I was not drunk. I walked in a perfectly straight line.
Is the speed it gives more or less accurate than a bike computer? Does it somehow correct for the wobbly path and determine how fast and far you actually went?
