Goose Morse - learn Morse Code

Learn Morse code by ear — not by counting dots and dashes.

GooseMorse is a focused trainer for amateur radio operators, preppers, aviation buffs, and anyone who wants to actually hear Morse — not stare at it on paper. It is built around the Koch method: you start at full character speed with two letters, then unlock new characters as your accuracy holds.

WHY KOCH
The Koch method is the most efficient way to learn Morse code. From day one you listen at real-world speed — no slow ramp-up, no mnemonics, no charts. New characters are added only when you can copy them confidently, which builds deep letter-by-sound recognition.

WHAT YOU GET
• 25 progressive lessons, from K & M to the full alphabet
• Group dictation practice with upfront playback and typed copy
• Flip Challenge — a fast card game: hear a row of characters, type your copy, flip the cards to check, and chase your accuracy and reaction time across multiple rounds
• Farnsworth spacing — slower effective speed without losing real timing
• Lesson phase for every new character — guided recognition, then mixed drill
• Error reinforcement — weak characters surface more often in future sessions
• Per-lesson progress: accuracy, streak, and error history
• 5 visual effects — pulse wave, waveform, constellation, decode ring, and flashing lamp
• Adjustable tone (Hz), character speed, effective speed, group size, and volume
• 3 keyboard layouts: alphabet, QWERTY, Koch order
• Bilingual: English and Simplified Chinese
• Dark and light themes
