Anybody using their phone for a cycling computer?
I started thinking about this last year, and never bothered to research it. I'm certain it's already out there. I figure I already carry it, and had thought about using the GPS and map for rides that go out a little further than usual, all I'd need is a mount for it. And if I'm going that far, I'm sure it could do double duty and replace the little pos cadence/speedo counter I have on the bike now. I'm also sure I could find something that would let me use a chest strap heart rate monitor as well. Then I start to get a head ache and forget about it.
So who can recommend a way to tie my smart phone in with a HRM, and a cadence sensor. The rest is already covered.
