[iPhone God App] It was found using the g-tac pro actually

g-tac pro uses the accelerometer and GPS in iPhone or iPod touch to track and record the performance of your vehicle at the circuit or the drag strip.

Response to scareyourpassenger's review:
Google maps is *not* more accurate. Maps often misplaces your position by 100's of yards briefly and then snaps back. g-tac pro won't do that, but that also means you have to wait for an accurate gps lock which can take a minute or two. If you start without waiting for a lock it says "no gps". It's not a hardware connection problem. Also, the exported data *is* in CSV format. Apple's mail app doesn't allow 3rd party apps to create emails with file attachments, so the CSV data is placed in the email body. Just cut and paste into a file.
