Synchorus - Synced Speakers

Synchorus connects several phones over Wi-Fi and plays the same music on all of them at once — like one big speaker.

One phone (the host) plays; every phone that joins the room plays the exact same thing, precisely in sync. Camping, home parties, rehearsal rooms, picnics — whenever one speaker isn't enough, gather the phones around you and turn up the sound.

■ Key features

- Precise synchronized playback: multiple devices matched to the millisecond

- Easy to connect: join with a 4-digit room code. No server, no account, no login

- Host and speaker roles: one phone controls playback, the rest play along

- A-B loop and saved positions

- Pitch (semitone) and playback speed control

- Shared metronome: the same beat on every phone in the room

- Playlists organized by album

- Background playback with lock-screen and notification controls

- Works on phones and tablets (two-column layout on larger screens)

■ Made for

- Camping, picnics and home parties where you want more sound

- Band or ensemble practice: everyone hears the same track from their own phone

- Practicing alone: slow the song down, transpose it, loop a tricky section

- Anywhere you need more volume than one phone can give

Synchorus also works on a single phone as a regular music player, and the loop, speed and pitch tools are especially handy for learning an instrument.

Everything runs directly between your devices (peer-to-peer) on your local Wi-Fi — nothing is uploaded to a server, and we don't collect personal information.

The free version shows ads and syncs up to 2 devices. A one-time Pro purchase removes ads and lifts the device limit.

Pro is a one-time purchase on Google Play.
