乃木坂46リズムフェスティバル is a rhythm game for iPhone developed by AiiA Corporation. The game is free to download and categorized under games. The game offers a unique experience by blending live footage of actual performances by the band with gameplay. The music tracks are also live versions which add to the immersive experience of playing along. There is a special feature called the Focus Movie which is a game-exclusive live footage centered around a particular band member. These are available as prizes to be won in the game. The app also promises monthly updates with new live footage and music tracks. It is available on iOS 10 or later, and while other operating systems may be compatible, the developers do not guarantee smooth operation on them.
