One room.
Every device in control.
BallroomSync turns a studio full of phones, tablets, and desktops into a single music player. Drive class music from your phone while the studio sound system plays from the master device — every screen shares the same queue, controls, and now-playing state.
One output, many remotes.
The active master device owns audio playback, so the room sounds clean through the studio system instead of echoing from every phone. Streaming sources play from the master while every other screen shows the live now-playing state — and any device can take over with one tap.
Built like a studio console.
Every control you'd want on the floor — queue, tempo, fades, transport — shared across the room and tuned for live teaching.
Shared rooms
Every device in a room sees the same queue, now-playing, and controls; co-control playback from anywhere in the studio.
One master device
Pick which device drives the speakers; the rest mirror it and can take over when promoted.
Shared control
Queue edits, transport buttons, BPM changes, and playback status flow through the room so every controller stays current.
Folder-tree library
Organize tracks in nested folders per dance, level, or class; share whole folders or your whole library, read-only or read-write.
Playlists with fades
Schedule a class as a timeline: per-song fade-out, breaks, and filler between tracks. Set once, run every week.
BPM & tempo control
Automatic BPM detection plus pitch-preserving speed control; set a target tempo per folder and every track snaps to it without sounding chipmunked.
Spotify & YouTube
Pull in tracks from Spotify and YouTube alongside uploads; streaming sources play from the master with full metadata everywhere.
Cross-platform
One app on Windows, Android, iOS, and macOS; sign in with Google or Apple and your library follows you everywhere.
Scan. Drive. Dance.
Scan the room QR
The studio desktop shows a QR code; scan it from your phone to join the room and become a controller instantly.
Drive from your phone
Build the queue, set tempos, hit play; big thumb-reachable transport controls readable from across the floor.
The studio plays
Audio comes out of the studio sound system while every other device stays in control; hand the master role over at any time.
One clock, one room.
Uploaded tracks play in lockstep; the sync engine targets five milliseconds or less between devices on the studio network — tighter than a single video frame.
One clock, one room, every speaker on the same beat.
