Customer Reviews

Very very useful!!

AWESOME for Auto Cross! Although the iPod touch doesn't run the GPS features, this app still brings a lot to the table. Much less costly than a dedicated commercial version and worth every penny!

Not accurate pro features should be on $9.99 app

Always records bad speed. Disapponted after paying 9.99 that there is now a $20 app with updates

So stupid. Does not work at all!!

I want my money back for this joke of an app. A 3 year old night enjoy this as it does not work in any way at all. Stand still and it says your accelerating.
