Turn your phone into a Morse code beacon. SOSLight blinks your flashlight (or full-screen white light) in international Morse code so rescuers, hikers, and sailors can spot your signal in the dark. When the power is out, when you are off-grid, or when you simply need to be seen — tap a preset and let the light do the talking. KEY FEATURES • Plain flashlight mode — one tap for instant, steady light • Built-in emergency presets — SOS, HELP, FIRE, MAYDAY, CQD, SOS-PAN, recognized worldwide • Custom messages — type any phrase and it is converted to Morse automatically • Infinite loop playback — keeps signaling until rescuers arrive • Automatic fallback — uses the screen as a beacon on devices without a torch • 100% on-device — no network, no account, no ads, no tracking WHO IT IS FOR • Hikers, climbers, sailors, and night cyclists who need a visible distress signal • Anyone preparing for power outages, earthquakes, or natural disasters • Students and hobbyists learning Morse code • Outdoor enthusiasts who want a dependable signal light PRIVACY SOSLight does not access your camera images, photos, location, or network. The only permission it requests is flashlight (torch) control, and nothing is collected, stored, or transmitted off the device. Emergencies do not announce themselves. Keep SOSLight on your home screen and call for help with light when seconds matter.
