Signal Beacon sends and reads messages by light, so you can reach someone when there is no cell signal, no Wi-Fi, and no time. BROADCAST • Flashlight: your phone's flashlight blinks your message in Morse code. Anyone with Signal Beacon, or who knows Morse, can read it from far away with a clear line of sight. • Screen code: show a code on your screen for a phone held up close. Send longer messages, your location, even a photo. • Quick messages for SOS, need help, injured, lost, I'm OK and need water. Add your coordinates so a rescuer knows where you are. • The screen goes dark while it signals to save battery. SCAN • Point the camera at a blinking light or a screen code to read it. • Tap the light to lock on. Automatic sensitivity adjusts to day and night, and the reader holds on through a shaky hand. • Received messages show the distance and direction to the sender. • Turn any message into a short video clip to share, with real camera footage or a clean light animation. TALK • A two-way conversation over light between two phones, up to line of sight. One phone calls, the other answers, and each line you send is confirmed with a receipt. MADE FOR THE FIELD • Works with no signal. Nothing is uploaded; the app has no accounts, no ads and no tracking. • Red night mode protects your night vision. • Plain, rugged controls you can use with cold hands. MORE AT SIGNALBEACON.APP • Read a beacon in any phone's browser, with no install. • Learn to read Morse by light in a free game with daily challenges and leaderboards. SAFETY Signal Beacon flashes a light rapidly. Do not use it if flashing lights can trigger seizures or migraines for you or anyone nearby. It is an aid, not a substitute for emergency services: if you can, call your local emergency number.
