It looks like THEATRHYTHM FINAL FANTASY is coming to iOS!
A listing on the New Zealand iTunes store shows the free app which includes two songs. Players wanting more out of their music rhythm experience will be able to purchase additional tracks as well as new characters.
New to the iOS version is the ability to Tweet out scores in addition to the Compose Scores mode. This mode allows players to create their own original score to share with others, or to challenge a score made by someone else.
You can find all of the information on the New Zealand iTunes page here. Presumably this will make it to other regions later today.
