About this app

LED Messenger turns your phone's flashlight into a Morse code transmitter and your camera into a Morse code decoder. Send and receive text messages using light alone — no internet, no Bluetooth, no Wi-Fi, no account.

HOW IT WORKS
Type a message and LED Messenger converts it to Morse code, then transmits it as flashlight pulses. The receiver points their camera at the flashing light and the app decodes the signal back into readable text as it arrives.

SEND MESSAGES WITH LIGHT
• Type your message and tap Send
• Your flashlight blinks the Morse code automatically
• Four transmission speeds, from 3 to 10 words per minute
• Watch the dots and dashes scroll past as they go out
• Works on any phone with a flashlight

RECEIVE AND DECODE LIGHT SIGNALS
• Point your camera at the sender's flashlight
• Real-time decoding, letter by letter
• Calibrate light detection for the room you are in
• Works in bright or dark conditions

SECRET MESSAGES, ENCRYPTED
Secure Messaging is an optional one-time purchase. It scrambles your message with a password before it is ever turned into light, so anyone else pointing a camera at the same flashlight sees only nonsense. The recipient needs the same password, and Secure Messaging of their own, to read it. The encryption adds only three characters to a message, so an encrypted transmission takes barely longer than a plain one.

KEY FEATURES
• Fully offline — the app requests no internet access at all
• Full message history, sent and received, grouped into sessions
• Adjustable speed, from beginner to fast Morse
• Light calibration for any lighting condition
• Standard ITU Morse: A-Z, 0-9 and common punctuation
• No ads, no accounts, no tracking, no servers
• 13 languages — English, German, French, Spanish, Italian, Portuguese, Russian, Turkish, Japanese, Korean, Chinese (Simplified and Traditional), Arabic

PERFECT FOR
• Learning Morse code interactively
• Sending secret messages with friends
• Educational projects and science demonstrations
• Scouts, camping and outdoor activities
• Practising emergency light signalling
• Party games and team activities

A communication tool that puts classic Morse code on modern hardware. Point, flash, and communicate.

Note: LED Messenger is for learning and recreation. It is not an emergency service — never rely on it where a real distress signal is needed.
