The latest version of Magic Guitar, released on Dec. 14, has several new additions, including new songs and the ability to add vibrato to the guitar. The app allows you to play a guitar without spending a fortune on an actual one. After downloading the app, your iPhone turns into a guitar. Beams of light will approach your fingers, and by pressing and holding them, you can hear each note. Shaking the phone brings new fun to playing the guitar. There are plenty of your old favorites on the app, with songs by KISS, The Rolling Stones, Sublime, Lady GaGa, Santana, and others. You can even pick different guitar sounds, such as electric or acoustic if you prefer. You can share the songs you've played on the app via social media, including Twitter, Facebook, and email. Once you've mastered your new guitar, you get rewarded for playing. As you become better on the app (which was admittedly a little hard to get used to), you can unlock certain achievements, such as new songs and move towards the top of the points leader board.
