Turn any crowd into a synchronized light show — no Wi-Fi, no Bluetooth, no venue hardware. Litwave flashes your screen and flashlight together, in perfect sync with every other phone in the crowd. There's nothing to pair and nothing to configure: sync is based on the clock already in everyone's pocket. PERFECT FOR FLASH MOBS AND EVENTS Planning a surprise? Organizing a crowd moment? Litwave lets you choreograph a light show for any group — a birthday, a stadium, a street performance, a festival — with nothing more than a QR code and a shared moment. Create an event, set the time, and share the link. When the countdown hits zero, every phone flashes the same message in Morse code, in unison. FOR ORGANIZERS • Create named events with a scheduled start time • Share via QR code, link, or any messaging app • Recipients import in one tap — no account needed • Works for groups of 5 or 50,000 FOR PARTICIPANTS • Scan a QR code or open a link to join an event • Press start — your screen and flashlight begin flashing in sync • No pairing, no Wi-Fi needed, works in any venue HOW THE SYNC WORKS Every phone already shares the same atomic clock time. Litwave uses that clock to align all devices automatically — the same principle that keeps GPS satellites in sync. No coordination between phones is ever needed. CUSTOMIZE YOUR MESSAGE • Built-in presets for concerts, sports, and celebrations • Type any custom message — Morse code is generated automatically • Supports Latin, Cyrillic, German, Scandinavian, and more PRIVACY FIRST Litwave is fully offline.
