Featured App: Simple Piano Tiny Motzarts and bitty Bethovens, have we got an app for you! Simple Piano is, well, exactly that. Fourteen piano keys -that's almost two octaves for you musically inclined folks, make up this really very simple piano playing app. Original piano music is all that's played inside this app from developer EH Media. No pre-recorded songs means no watching the app play by itself. If your kiddo can imagine it, he can play it on this iPad only keyboard.
