Morsenger

Morsenger is a completely free Morse code toolkit for learning, encoding, and decoding.

Morsenger is a complete Morse code toolkit for learning, encoding, and decoding — built for students, history enthusiasts, amateur radio operators, and anyone curious about the language that changed the world.

DECODE Listen through your device's microphone to decode Morse code signals in real time. A scrolling waveform timeline shows signal activity as characters are recognized. Import audio and video files (WAV, MP3, M4A, FLAC, AIFF, and common video formats) to decode recorded transmissions. The decoder auto-detects frequency and words-per-minute, adapting to noisy or imperfect signals. Gap-based decoding also recognizes percussive tapping — tap on a desk, table, or any surface and watch your message appear.

ENCODE Type any message and hear it rendered as authentic 1970s-style Morse audio. Export recordings in Apple Lossless format or share directly via iMessage. Stealth mode shifts the tone to near-ultrasonic frequencies for transmissions that are virtually inaudible to most listeners.

TELEGRAPH KEY An interactive key turns your device into a working telegraph station. Use mouse clicks, touch, or keyboard input to send Morse with real-time audio feedback. Your transmitted characters are decoded and displayed as you key them.

GAME Learn Morse code through a hangman-style game with word and phrase modes across multiple difficulty levels. The game draws from a curated library of over 1,500 WWII military messages, making practice both educational and historically grounded.

PRACTICE A dedicated practice mode lets you study letter by letter. Tap the play button to hear the correct dit-dah pattern for any character, then build speed and confidence at your own pace.
