I've been using an iPhone app that lets me record by cycle rides (time/distance/route), but the last couple have resulted in route maps that are wildly off from the actual route. So is the iPhone a true GPS device like a satnav? I'm sure my Tom-Tom would have been ok, it's just annoying because half way around my loop it seems a warning that 'GPS had been lost' came up the phone's screen but of course unless you stop to look at it you wouldn't know. Or, as I suspect, is it using the mobile network to work out my position in which case I can sort of understand some of the problems in the high banked narrow lanes but my route start is out in the open where I get a strong 3G signal.
I forgot to mention that the app I'm using is called Strava, can anybody recommended any of the other cycle apps out there that might give me a better result or will they all roughly be the same?
