MUCH PETTER THAN EXPECTED!

When I naught this app, I thought it was going to be a bust. I didnt have one of those fancy iPhone holders for my car and was not expecting much accuracy. So I placed it in my cup holder and let me tell ya... IT WORKS PERFECTLY. The slightest of brakes are monitored! Its amazing

I just wish they had other cars and for much cheaper

They should have a preview of the car sounds so you have an idea what youre buying.
