Synchorus

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.
