Key it yourself, hear every mistake named
Morse code is a rhythm: a short dit, a long dah, and three sizes of gap. Morse Tutor checks your keying against standard Morse timing and names each mistake as it happens, then lets you copy beeps by ear at your own speed.
This is a home practice tool, not a teacher, therapist or safety device. Everything runs on your device: no video, audio or images are sent anywhere. Feedback is automatic and can be wrong. For real instruction, learn from the amateur radio community, linked on the Resources page.
Speed
1 unit = 100 ms · dit 100 ms · dah 300 ms
At 12 WPM a dit lasts 100 ms and a dah 300 ms. Slower speeds give you more time; faster speeds are closer to real on-air code. Standard timing: dit 1 unit, dah 3 units, gap inside a letter 1 unit, gap between letters 3 units, gap between words 7 units.
6 levels, from first dits and dahs to full phrases. Pass any item in a level to unlock the next. Quiz mode hides the code and scores 5 items from memory. Copy mode plays beeps and you type what you hear. Points for every pass, a bonus for a perfect key, and badges along the way.
