Android users have had access to Attack on Titan: Assault since last February, but fans of the show with an iOS device can finally join in as well, since the game is now available as a free-to-play RPG, combining "elements of an RPG and runner features in order to replicate the fast-paced action of the titan battles from the anime series".
Developer Gamesamba also promised regular updates and events for both versions of the game. You can get the iOS version here and the Android version here, if you're interested in exploring more of the Attack on Titan universe.
