Morse Cat is yet another Morse code training tool. But this one is special. And not just because it’s relying on the appeal of cats to draw your attention. It is special because it gives you immediate feedback when you make a mistake.

This project relies on on jscwlib to actually produce sounds. This is the JavaScript library that powers LCWO.

Supported languages: English, French, Japanese, Spanish, Catalan, Mandarin, Hindi, Arabic (RTL), Bengali, Portuguese, Russian, Urdu (RTL).
