Questions
Which phones does Mix Master run on?
iPhone with iOS 18 or later, and Android phones with Android 9 or later. It plays in landscape, like a DJ box on the table.
Where do the songs come from?
Songs you own, as files. On iPhone: the Files app (including iCloud Drive and other file providers), AirDrop or Share › Mix Master from another app, file sharing from a Mac's Finder, and songs in your music library that you bought or synced from a computer. On Android: tap + ADD in the library and pick songs from your phone. A demo crate is there to start with.
Common formats such as MP3, AAC/M4A, WAV and FLAC work.
Why can't I mix songs from Apple Music, Spotify or YouTube Music?
Songs from streaming services are copy-protected, even when they're downloaded for offline listening, so no DJ app can read their audio without a deal with the service. Mix Master tells you when a song can't be mixed for this reason.
How do I get a guest DJ to mix?
Load a track on each deck, then tap the record in the mixer to open the DJ booth. Pull a DJ from the crate, pick their style and hit MIX: they read both decks and play the transition. Grab a fader any time to take over.
What are stems, and why does preparing them take a while?
Stems are the parts of a track, such as the vocal, separated so you can turn them on and off. Mix Master separates them on your phone, so the first time can take from under a minute to a few minutes, depending on the phone and the track. After that they're kept, and load in about a second.
Is there a subscription?
No. Mix Master is a one-time purchase: no subscription, no ads and no account.
Where are my recorded sets?
Open MENU: your recorded sets are there, next to the settings.
I got a new phone. Do I have to buy it again?
No: download Mix Master again with the same Apple ID or Google account. (A purchase doesn't carry over between iPhone and Android.) Your songs, stems and sets live on the old phone and we don't sync them, so bring them over with your phone's backup or add the songs again.
How do I delete my data?
Everything Mix Master stores is on your phone, and deleting the app deletes it. We hold nothing about you. See the privacy policy.
