SyncLight turns every phone in the room into one synchronized light show. Create a room, friends join with a code or a QR code, and every screen flashes, pulses and changes colour together, on the beat. Perfect for parties, birthdays, weddings, concerts, festivals, clubs, school and church events, and cheering in the stands.

No subscription • The same room code and QR code for the whole event SYNCLIGHT PRO • Every VIP effect with no time limit, torch mode, your own effects and playlists for the whole room, rooms of up to 50 phones and a Pro host badge • Coming to Pro: DJ mode, music sync and event mode • Without Pro you can try VIP effects for 3 minutes at a time HOW IT WORKS SyncLight sends only tiny timing messages, never video. Each phone draws the light itself, so the whole room stays in sync, on Wi-Fi or mobile data. SAFETY Some effects use bright, flashing light. A safety warning appears before they play, and flashing is kept to a safe rate. Stop if anyone feels unwell. SUBSCRIPTION Payment is charged to your Apple ID at confirmation of purchase.
