Hi everyone. I would appreciate your thoughts on choosing a cycling app for the iPhone.

I know there are many out there, and that's the problem . . . Here are my criteria, and I hope this is of somewhat general interest.

1. Records location, speed (avg, max, current), elevation, total climb, percent grade.
2. With not-crazy-expensive sensors, also records heart rate, cadence, calories.
3. Can view those data on the iPhone (after the ride), as well as uploaded to a good website. It would be nice to click on a point on the route and see "ok, here it was a 10% grade, I was managing 12 mph and pushing at 180 bpm, my cadence was 100 rpm and I was pushing a 3.2 gain ratio", etc.
4. Adjusts for time stopped, so that you don't have to remember to pause/resume.
5. The phone is sitting in your pocket or bag, not on the handlebar, and the battery on the phone can last for a several hour ride, even a century ride.
6. Can record which bike you were on, the weather, whatever other info you care about.
7. I'm happy to pay for a good app.

Any suggestions? I'm trying Strava right now. It seems about 80% of the way there, maybe.

I'm going to ride the STP for the first time this July, so I am trying to start tracking my rides and conditioning and performance, with the app that I settle on.

Thanks.
