Touch Piano, play the piano on your phone!

Got a talent for creating music, here's an application that'll help you while on the go.

Touch Piano is a freeware which basically offers the functionality of full piano to play on your phone.
This app comes with a lot of customizable options and skins, However in my honest opinion it's not the best at registering touch and there seems to be a lag between pressing a key and hearing the sound.

You can try it for yourself, Download here.
