Acceleration

Won't record or even show the highest value. Completely useless app. Rather have just burned the $1.

Very annoying that you cant save old data from graph. Only real time.

The only way one can see the result -- real time. No recording. This makes app not very useful, because while I am jumping/driving/diving I have no time to look at the screen, but after -- the info is gone.

Would like to be able to save the data for later viewing. Also, x,y,z is relative to what?? A fixed orientation of the iPad? If so, what is it? During braking, the values seemed appropriate, but during acceleration, it clearly was off by a significant amount.
