On July 31, 2012, due to an expiring contract with Rock Band main developer Harmonix, the game was removed from the App Store.

While vocal gameplay has traditionally been done using a microphone in conjunction with a player literally singing words in pitch, the game uses only rhythmic touch input.

The game features two main single-player modes known as "Quick Play" and "World Tour".

Players are able to download additional songs in the in-game "Music Store", which is available using Wi-Fi or a cellular data connection to the internet.

Common criticisms by reviewers consisted of the lack of ability to sing vocals such as in the console counterparts of the game, and the limited soundtrack out of the box.
