this application turns your mobile into a virtual drumstick
which produces 3 different drum sounds for 3 different phone movements

the mobile must be held vertically with the screen looking to the left

if it is flicked backwards (meaning that the mobile will end up looking down) it produces a bass sound
if it is shaken in parallel to the ground it produces a snare sound
and if it is flicked upwards (meaning that the mobile will end up looking up in a 45 degrees angle) it produces a crush sound

the accuracy of the application depends heavily on the response time of the mobile's accelerometer
and the users skills
have this in mind before blaming the application
if the application does not response as it should , try to free up resources and close other applications

Don't use force . it is no needed and there is a risk of slipping you phone out of hands.
be careful and use at your own risk
