Car accelometer for IOS devices.

I would like to have small app that shows speed, acceleration, gradient of car (when device has a fixed position in car) and G force effect on driver. I would like it have to both analog and digital output screen options. Also Tracking drive records, highest G Force ever, Acceleration ever, speed, gradient and spin if possible would be good addition. Will be in English, Turkish(I will help translations), Russian(I will help translations) and any other language you can add would be awesome.
