Are you looking for an iPhone app that can track your speed, lean angle and plot it out onto a map
Well look no further
You need to download diablo super biker It's easy to use and tracks everything just open the app, choose track or road then hit the big red start button and put the phone in your pocket It will then track your session using gps and give you some stats at the end and plot everything out onto a nice map for you

Another handy iPhone app I've found is "velocimeter"
It's pretty basic but it records top speed, 0-60, 1/4 mile and 1/2 mile. Handy for those top speed sprints Although the times in the picture aren't totally accurate because I was moving before I went for the blast

On the first one, surely once you press start and put it in your pocket before you even move it could be saying 10-20 degrees, make people think they're motogp stars when it comes up as 70 degrees!

Yeah know what you mean but it seems quite accurate and here's a snap of the in app FAQ Seems they have taken that into account

That would have been my solution, relative start position, I dont have an iPhone so can't get it

Yeah I think they have it covered lol
I've looked at loads of apps like these and most of them are aimed at cars, you put the phone on the dash and it uses the motion sensor to set it going, not good for bikes
These are the 2 best ones I've found so far for bikes, they use gps to start the timer so you just chuck it in your pocket and go.

There's probably apps similar for your phone,
Feel free to post if you find any
