Usefulness is limited by Apple
This is potentially a great app, but there is a big problem that isnt Pascos fault - the acceleration data is limited to about 2.3 gs in any given direction (and the resultant will be incorrect as a result also). This is Apples fault - they limit the accelerometer to +/- 2g when it could do +- 8g (but not as smooth). If you want good data collection you are going to have to shell out big bucks for Pascos interface and probeware. Otherwise its not useful in collecting acceleration data above 2g.
