Took one for the team
The speedometer wildly fluctuates even while driving a steady speed on cruise control. The odometer/distance function seems pretty accurate, at least in comparison to the speedometer. I don't trust the acceleration numbers.
I was hoping for functionality like Race Logic's VBox Sport Performance Test app that would work with the internal GPS or more accurately with others like my DualAV XGPS160 that is very accurate and updates 10 times per second (10x faster than internal iPhone 4S GPS).
I hope the developer keeps updating this app, so it can provide better functionality that is actually useful. I wish I got the freebie app first.
