SyncSong plays the same music, at the same moment, on several phones at once. One phone is the host: it holds the music and controls playback. Every other phone joins as a client, receives the songs it does not already have, and follows the host's playhead in real time. Press play once and the whole room hears it together. NO NETWORK REQUIRED Phones find each other over Bluetooth LE, so SyncSong works on a walk, in a park, in a car — anywhere, with no shared Wi-Fi and no internet connection at all. On a network you know, switch to Wi-Fi instead for much faster song transfers. The choice is a single tap on the home screen and it is remembered. NOTHING TO SIGN UP FOR There is no account, no subscription and no cloud service. Your music never leaves the phones taking part. Hosts are discovered automatically on the same network; if discovery is blocked, a host's address can be typed in by hand. STAYS IN STEP The client measures the round trip to the host rather than trusting the two clocks to agree, so playback stays aligned even when the phones' clocks differ. Drift is corrected continuously, and a per-host offset control lets you nudge the timing by hand if one phone's speaker or headphones run behind. BRING YOUR OWN MUSIC Add songs from your music library, from Files and Downloads, or from a direct link to an audio file. The host's library is shared with everyone who joins. WHAT IT IS NOT SyncSong is not a streaming service and has no catalogue of its own. It plays audio files you already have. It cannot play music from a streaming subscription, and it cannot export DRM-protected tracks from your library. Up to four phones can follow one host at a time.
