for all you silly gooses who think its not very accurate

1. first of all its a phone you cant expect it to be very accurate

2. its works ALOT better with a iphone 4 which has a gyroscope

3 it works best when actually clipped into the car and not in your hand or something

its an awesome app and the readings are close enough
AND even if its crap (which its not) it a free app so its not like your losing anything
good job BMW :)
