Learn Morse by ear with Koch lessons, offline AI audio decoding, CW copy drills, sending practice, progress, badges, and no account.
Morse Master helps you learn Morse code by ear with a structured Koch-method path and practical CW drills. Instead of memorizing dots and dashes from a chart, you train the sound patterns used in real copying and sending.
Training:
- Progressive Koch lessons that introduce characters step by step
- Daily Sprint sessions for focused 3–5 minute practice
- Listening and receive drills for Morse copy
- Sending practice for rhythm, timing, and keying control
- Weak-character review and confusing-pair drills
- Adjustable WPM, Farnsworth spacing, pitch, noise, and fading
- WPM Ladder, Free Range, and copy practice for extra reps
Signal tools:
- Text to Morse and Morse to text conversion
- On-device audio decoding from recordings or microphone input
- Flashlight Morse transmitter
- Training history, progress, badges, and weak-character review
Morse Master works offline and does not require an account. It is built for beginners, ham radio learners, and CW operators who want a clear daily path from first sounds to steadier copy and sending.

Morse Master 3.3.0 fixes how your training results are recorded:
- Sending and copy results used to be recorded as listening scores, which put the wrong characters on your review schedule. This version records them separately by source, so each skill is scored on its own.
- Your review progress is kept as it is: Koch stage, streak, rank, review intervals and full training history all carry over — nothing starts again. Over the first few days each character comes up for one review so the schedule can realign with how you actually hear it.
- Copy practice now uses aligned comparison: one missed character no longer marks the rest of the line wrong.
- Manual corrections in audio decoding no longer count as listening errors — you are correcting the decoder's output, not your own hearing.
- Added real-word copy practice; weak-character detection now uses recent performance.
