Decode morse code with your camera. Send via flashlight. Chat using light.
Decode, send, and learn morse code — all with your phone's camera and flashlight. No internet required. The only morse code app that combines real-time light decoding, flashlight transmission, and two-way chat. ▶ DECODE WITH YOUR CAMERA Point your camera at any flashing light. The app samples brightness in real-time and translates the flashes into text. Adjustable threshold, zoom up to 10x, and exposure controls let you read a signal across a room, across a field, or in full darkness. ▶ SEND WITH YOUR FLASHLIGHT Type a message and transmit it via flashlight or screen flash. 4 speed presets from 6 to 24 WPM. 24 quick-tap presets for emergency, status, navigation, and common phrases including SOS, Need Help, and I Am Safe. ▶ CHAT USING LIGHT Two-way real-time conversation. One phone flashes, the other decodes. Messages appear in a chat interface with timestamps. Audio morse via speaker and microphone is supported too, for when line of sight isn't available. ▶ LEARN MORSE CODE Practice with interactive quizzes in two directions: identify the code for a character, or the character from a code. Track accuracy, build streaks, and master every letter and number. Supports both international and Russian (Cyrillic) morse code. ▶ REFERENCE GUIDE Complete morse code chart with letters A–Z, numbers 0–9, punctuation, timing rules, and an SOS reference. Morse code numbers are always five symbols: 1 = ·–––– 2 = ··––– 3 = ···–– 4 = ····– 5 = ····· 6 = –···· 7 = ––··· 8 = –––·· 9 = ––––· 0 = ––––– The SOS distress signal is ··· ––– ··· — three short, three long, three short. ▶ BINARY PROTOCOL Advanced error-corrected communication. Manchester encoding with CRC-8 checksums for reliable transfer even in noisy conditions. The app auto-detects whether an incoming signal is standard morse or a binary packet. ▶ SAFETY Photosensitive epilepsy warning on every launch. Screen-only safe mode. Flash frequency is hardware-limited.
