Sync DJ

Music

Free · Designed for iPad. Not verified for macOS.

Sync DJ turns a group of phones into one synchronized sound system. Load the same DJ mix on each device, agree on a drop time, and hit play — every phone locks to the same position in the track. How it works 1. Everyone picks the same audio file from Files or iCloud 2. Set a shared drop time — or send a one-tap syncdj:// link 3. Tap play — the app jumps to exactly the right position 4. If you pause or lose connection, tap again to rejoin mid-mix Internet time sync Sync DJ uses network time (NTP) to correct for differences between device clocks, so the drop lands at the same real-world instant on every phone — even if someone's clock is off by a few seconds. Live spectrum analyzer A real-time frequency visualizer reacts to the music as it plays, with multiple colour themes to match the vibe. Built for long mixes Hour-long sets, multi-hour mixes, all-day playlists — the playback engine handles it. Background audio keeps the music going when the screen locks. No accounts. No streaming. No internet required after sync. Your audio files stay on your device. Sync DJ doesn't stream, upload, or share anything. The only network call is a single time-check to align clocks.
