Knock On Wood is an entertaining way to ward off bad spirits. By touching different parts of the wood, you can get different sounds. If you enjoy the sounds, you can use it as an amazing ringtone, notification sound, or alarm. There are many types of wood that you can choose from:
Bakau
Beech
Birch
Bog Oak
Cherry
Douglas
Knotted
Mansonia
Maple
Mariposa
Padauk
Pine
Poplar
Rosewood
Scots Pine
Sinchewitz
Walnut
If you are not sure if you want to use the specific type of wood, just try it and you will know what sound it is. It is best to use the full version of the app because you will not be able to get all the different types of wood.
