great app for demonstrating the difference between 1st and 2nd order vibrations
After seeing the app on youtube and thinking this was the app it definitely isn't... All this app does is make your phone vibrate so you can understand "1st order or 2nd order... what a waste. And I'm sure not downloading the other app for $399...
Could not put any info in and it would not do anything
Does what it sets out to do: it makes your phone vibrate at a specific frequency. it is helpful in diagnosing car vibrations, but you have to have some idea of exactly what you're trying to diagnose
