Using your device’s gyroscope, Rassel turns your phone into a fun, and surprisingly realistic shaker. It’s quite uncanny how the shaker feels and sounds in the hand, and the app is very intuitive and easy to use. Rassel comes with four different instruments: egg, shaker, tambourine and bells (ready for Christmas time..!). There is also a loudness dial to increase the volume of each of the sounds alongside the ability to include background sounds. This allows you to shake along to songs playing in another app on your device, great for individual practice..!
