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 60-second 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, including Russian, Greek, Japanese Wabun, and Chinese telegraph code
- On-device audio decoding from recordings or microphone input
- Flashlight Morse transmitter
- Training history, progress, badges, and weak-character review
Beyond the app:
- Morse keyboard: type in Morse in any app, with one-key or two-key input
- Apple Watch: check your progress and run listening drills on your wrist; results sync back to iPhone
- Home Screen and Lock Screen widgets for today's Sprint, your streak, and due reviews
- iCloud sync across your devices (PRO)
Morse Master works offline, has no ads, 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.

I love the look, the feel, and the functionality of this app sm but after Koch stage 10 it makes you pay for a subscription to continue:(
Developer Response
Thank you for the kind words about the look, feel, and feature set. I understand the frustration when the Koch path reaches the subscription boundary after stage 10. We are adjusting that boundary so free learners get more room, with the free Koch path expanding to the first 15 stages. The core tools will remain available, and PRO helps cover the development and maintenance costs behind the full 40-stage course and ongoing improvements. Thanks for the fair feedback.
Morse Master 3.5.9:
- Playback now consistently follows your volume and Farnsworth settings.
- Fixed passage playback continuing after stopping and showing completion after an interruption.
- Improved CW result recovery, history deletion and free decode allowance recovery when saving fails.
Version 3.5.9
