The game features ten of Perry's hits to tap along to, including California Gurls, I Kissed a Girl and Hot N Cold.
The $4.99 game is launching the same week that Perry's new album is released.
"Katy Perry is one of the most popular artists on the planet right now and this app creates an entirely new and fun way for her millions of fans to enjoy Katy’s music," says Tim O'Brien, VP of business development at Disney Mobile.
