MorseBook
A CW reference you can hear, a straight key you can send on, and drills that keep you honest.

- A straight-key practice pad that decodes your own sending live on screen.
- Encode and decode drills with reveal-when-ready answers.
- Per-entry mnemonics, timing breakdowns, confusion pairs and operating history.
