Litwave

Crowd light shows, zero setup

Free · Designed for iPad. Not verified for macOS.

Turn any crowd into a synchronized light show — no Wi-Fi, no Bluetooth, no setup. Just a shared clock and a shared moment. 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. It collects no data, requires no account, and has no server. Everything stays on your device. Open source · Free · No ads · No tracking
