Turn your iPhone into a Morse code signalling torch. Type any message and flash it as light, tap out Morse by hand, or fire the universal SOS distress signal with a single tap. WHY SOS FLASHLIGHT & MORSE CODE? • Instant SOS — one tap flashes the internationally recognised distress signal, over and over, until you stop it • Text to light — type a message and the app converts it to Morse code and beams it with your LED torch or screen • Manual mode — tap out dots and dashes yourself using the front or rear light • Learn as you signal — watch each letter translate to Morse in real time, the easiest way to pick up the alphabet • Save your messages — keep frequently used signals ready to flash in seconds PERFECT FOR • Hikers, campers, sailors and four-wheel drivers who want a backup signalling tool in their pocket • Anyone learning Morse code — practise by sending real signals, not flashcards • Getting noticed at night — a bright, repeating light pattern stands out far better than a steady beam SAFETY NOTE The light from your phone's LED or screen may not be bright enough to alert emergency services or be seen at long distances. Always carry certified signalling equipment and follow proper safety procedures — this app is a backup, not a replacement. Download SOS Flashlight & Morse Code today and put a signalling toolkit in your pocket.
