The Koch method
Start at full speed with two characters and add one at a time. You learn rhythm and sound, never dots-and-dashes on paper.

Without Memorizing
Charts
Train your ear using modern methods inspired by real-world CW operation. No lookup tables, no rote charts — just listen, recognize, and get faster.
Learn Morse. Hear Progress.
Built for real copy
Everything here exists to make you a faster, more confident operator — not to pass a quiz.
Time-to-recognize tracking
Every answer is timed from the last tone. The app knows not just whether you got it — but how fast — and drills what's still slow.
Confusion drills
It quietly learns the pairs you actually mix up (B/D, U/V, S/H…) and builds targeted sessions to sort them out.
Farnsworth spacing
Keep characters at full speed while stretching the gaps. Adjustable tone and effective WPM let you ramp up comfortably.
Hands-free Listen & Learn
Passive practice for the car or a walk: code plays, then the answer is spoken aloud — with full background audio and lock-screen controls.
Progress you can see
Per-character accuracy, median recognition time, and your most-confused pairs — weakest first, so you always know what to work on.
One character at a time
A staged ladder takes you from single letters to pairs, words, and call signs. Each character graduates only when you can copy it reliably and quickly.
- Sound-alike answer choices that mirror real on-air confusion
- Auto-advance on correct, instant reveal on a miss
- Opt-in punctuation and prosigns when you're ready

An honest trainer, built by a ham
Another Morse Trainer is a free, open-source app for iPhone. It was built the way a CW operator actually learns — by ear, at speed, focusing relentlessly on what you get wrong. Made for real copy. Made to help you learn.
