Frequently Asked Questions (FAQ)
Why is a GPS speedometer more accurate than a car speedometer?
Vehicle speedometers calculate speed using wheel rotations, which are subject to tire pressure and tread wear variations. A GPS speedometer measures true ground velocity using satellite geometry.
Does this app consume mobile data?
