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.

That’s amazing progress. Thanks for sharing it! Morse Master is built to make the first steps feel clear and fast, then help you keep improving with listening, sending, and daily practice. We’ll keep it focused and ad-free.

Thank you! We’ll keep improving Morse Master as a focused Morse learning and training app, with no ads and no unnecessary clutter.
Incomprehensible

Don’t waste your time or money. The software may be brilliant, but I never got it to work. Instructions, such as they are, were nearly impossible to find.
Developer Response
Sorry for the frustrating first experience. The current app has a clearer training path, onboarding, signal tools, and no ads, but we can still do better at making instructions easier to find. Thanks for calling that out.
Scammy ads
RapidGW
I tried to use this but it has very scammy adds saying your iPhone has a virus. Beware
Developer Response
We’re sorry you saw that. The current version of Morse Master has no ads and should never show virus-warning popups. Please update to the latest version; if you ever see anything like that again, contact us with a screenshot so we can investigate immediately.
