Morsenger vs MorseCAT

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.

Learn Morse code the way high-speed operators actually hear it: as sounds, not dots and dashes. MorseCAT is an Instant Character Recognition (ICR) trainer. Every character is sent at real speed from day one — you never count elements, you learn the sound. Then you answer the way an operator would: key it back. LEARNING IS FREE. FOREVER. • The full guided path — every letter, number, and prosign, in the proven CW Academy order • Listen & Learn — hear each character introduced as pure sound • Listen & Say — say the character out loud and MorseCAT grades you by ear • Free Practice — your speed, your character set, whenever • Word Patterns and weekly LICW class groups — drill exactly what your class covers • Progress that means something: a per-character mastery heatmap, recognition-time tracking, a copy-ceiling benchmark, streaks, and a proficiency rank ANSWER LIKE AN OPERATOR Hear a character, key it back. Use the on-screen straight key, the touch paddle, or plug in real hardware — Bluetooth MIDI keyers and paddles (TinyMIDI, HaliKey, VBand-style interfaces) take over automatically the moment they connect. Motor memory in, guesswork out. REAL SPEED, HONEST NUMBERS Characters always sound at your character speed (default 32 wpm, floor 25) — fast enough that there's no time to count elements, which is the whole point. Difficulty comes from closing the gaps, Farnsworth-style, never from slowing the code down. MorseCAT measures your time-to-recognize on every single character, so you always know which ones are instant and which ones still make you think.
