Morse Code - Decode & Chat
Flash Translator & Light Chat
Free · Designed for iPad
Decode morse code in real-time using your camera. Chat with friends via flashlight. The only morse app with error-corrected binary protocol for reliable light discussion.
Decode, send, and learn morse code — all with your phone's camera and flashlight.
Morse Code - Decode & Chat is the only app that combines real-time light decoding, flashlight transmission, and two-way chat into one tool. No internet needed.
DECODE
Point your camera at any flashing light source to decode morse code in real-time. Adjustable brightness threshold, zoom up to 10x, and exposure controls let you decode signals from across the room or across a field.
SEND
Type any message and transmit it via flashlight or screen flash. Choose from 4 speed presets (6 to 24 WPM). Quick-tap emergency presets include SOS, Need Help, I Am Safe, and more.
CHAT
Have a real-time two-way conversation using light. One phone sends via flashlight while the other decodes with its camera. Messages appear in a familiar chat interface with timestamps. Also supports audio morse via speaker and microphone.
LEARN
Interactive practice mode with two game types: identify the morse code for a character, or identify the character from morse code. Track your accuracy, build streaks, and master all 36 characters.
REFERENCE GUIDE
Complete A-Z and 0-9 morse code chart, timing rules, tips for best results, and SOS signal reference. Everything you need in one place.
ADVANCED: BINARY PROTOCOL
The only morse app with an error-corrected binary protocol. Manchester encoding with CRC-8 checksums ensures reliable data transfer even in noisy conditions. Auto-detects whether incoming signals are standard morse or binary packets.
SAFETY FIRST
Built-in photosensitive epilepsy warning on every launch. Screen-only safe mode available. Flash frequency is hardware-limited for safety.
