iDJ 2 GO is a revolutionary DJ mixing app for iOS. The app lets you mix, remix, scratch, loop, and pitch your music using two turntables. You can even mix with the sound of the crowd, the beat of the music, or your own voice. The result is an incredible mix that you can share with your friends on social media or in real-time.

The app has an intuitive user interface that’s perfect for beginners. You don’t need any prior DJ experience. Simply import your favorite songs from your iTunes Library, press play, and then mix the song with the music of the crowd, the beat of the music, or your own voice. You can mix and remix songs for free, or pay for the iDJ 2 GO Controller to mix with the iDJ 2 GO app for even more control.
