and lo and behold there was! im using "Move! bike computer" its free and seems quite clever so far, even plots your course on GPS and relays it over google maps! ithe accuaracy is here and there it picks up my rambling around some classic cars i found at the pier head but also nearly dumps me in the leeds/liverpool canal. some screen shots from my xperia P:
you can get stats from this section here while you are riding if you wish, however it runs happilly in the background even with an app killer working you will need GPS enabled though. i just put my phone in one of my frame bags
and here is a nice summary of the stats
the cool bit! where you can overlay onto google maps!
my only complaint so far? i cant find anyway to export to a KMZ file as it says you should be able to and exporting it to facebook does nothing but put an add of some sort on your post, rather than your stats and a map.
here is the info on the android store (or whatever google are calling it this month) I am not sure if there is a version on the Apple store, if there is i suggest you try it. Overall its pretty good for a free app!
if anyone has some other suggestions for cycle computer apps
all part of getting back into it and used to the bikes I may be able to ascend the hill on pontefract road again...
