SyncLight turns phones into a synchronized party light show for groups, rooms, events, and spontaneous nights with friends. Create a room, invite others with a short room code or QR code, then start a lighting effect from the host device. Everyone in the room sees the effect locally on their own phone, timed from a shared start signal for a smoother group experience. What you can do: • Create private light rooms in seconds • Join by room code or QR code • See members online before starting • Launch synchronized fullscreen effects • Use 10 included effects such as Flash White, Rainbow, Police, RGB Pulse, Breathing, Color Fade, Beat presets, and Firework • Rejoin recent rooms from history • Stop locally when you want to leave the effect view • Upgrade to SyncLight Pro for larger rooms with up to 50 members SyncLight does not stream video, audio, or animation frames between phones. It sends lightweight room and effect timing data so each device renders the light effect locally. Safety note: some effects include bright or flashing lights. Use SyncLight responsibly, avoid using fast flashing effects near people who may be sensitive to light, and stop immediately if anyone feels uncomfortable.
