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
