Read full description

Turn your phone into a Morse code signal light. SOS Beam sends real, correctly timed Morse code using your camera flash or your full screen. Tap once for SOS, or type any message and watch it flash out letter by letter. No internet, no account, no setup. TWO WAYS TO SIGNAL - Flashlight: your camera's LED flash, visible over long distances after dark - Screen: the entire display strobes bright white, for when your flash is unavailable or you want a wider, softer light ONE TAP FOR SOS The universal distress signal is always one tap away, and repeats automatically until you stop it. No menus, no typing. SEND ANY MESSAGE Type up to 40 characters. Full A-Z and 0-9 supported. Check the Morse preview before you send, then transmit it on a loop. CONTROL THE TIMING Three ready-made speeds: Slow, Normal and Fast. Or tune every interval yourself: - Dot duration: 50-1000 ms - Pause between letters: 100-1500 ms - Dash duration: 150-2000 ms - Pause between words: 200-3000 ms One tap restores the defaults. BUILT FOR ACTUAL USE - Tap anywhere on the strobe to stop instantly - Haptic feedback confirms every action - Signal counter tracks your transmissions - Works completely offline 18 LANGUAGES ... WHEN YOU MIGHT NEED IT ... free, supported by ads
