Morse Code - Decode & Chat

Asynk Tech

About this app

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
Point your camera at any flashing light. The app samples brightness in real-time and translates it to text. Adjustable threshold, zoom up to 10x,
and exposure controls work in any lighting condition.

▶ SEND
Type a message and transmit 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
Two-way real-time conversation using light. One phone flashes, the other decodes. Messages appear in a chat interface with timestamps. Supports
audio morse via speaker and microphone too.

▶ LEARN
Practice with interactive quizzes. Identify morse code from characters or characters from morse code. Track accuracy, build streaks, and master all
letters and numbers.

▶ REFERENCE GUIDE
Complete A-Z and 0-9 morse chart, timing rules, best practices, and SOS signal reference.

▶ BINARY PROTOCOL
Advanced error-corrected communication. Manchester encoding with CRC-8 checksums for reliable data transfer. Auto-detects standard morse vs binary signals.

▶ SAFETY
Photosensitive epilepsy warning on every launch. Screen-only safe mode. Hardware-limited flash frequency.
