I have currently been using an android based phone running mytracks and velox and am wondering if there is something similar offered for the Iphone 3G? Specifically, are there any programs that track speed, distance, elevation, location, trip time, etc. and can also display the route on google maps? If any of you have experience with these programs, what do you recommend?
I second MotionX GPS. Great interface, built-in iPod interface, easily integrates with Google Maps, etc. The only problem I've found is that it gives me a crazy reading for max speed (usually 100mph+). I'm guessing this is due to the GPS losing signal and then playing catch-up.
iRPM along with the SMHeartlink device to capture Speed/Cadence/HR/Power using the GARMIN GSC10 sensor. This is really very cool. pricey but it's my bike...
right now Apple's got serious problems with iPhone and GPS and WiFi connectivity. Am waiting and waiting ... for the next iPhone OS upgrade to 3.1 that is supposed to fix alot of problems that popped up with OS 3.0.
I have also seen huge speed spikes with runkeeper and i just read they are caused by your phone automatic time adjustment when switching cell tower. Turning it off (Settings - general - date and time) suposedly fixes the problem, at least for runkeeper... YMMV.
Looks easy enough to try.
What kinds of run times are folks getting with the GPS enabled on the iPhone? I have Motion X on my 3GS and the one time I tried it on a ride, I found a) the phone was running very warm and b) my battery was down significantly after around 90 minutes (I can't remember the exact figure, but it was <75%).
