Also working on a Korean guide, so far it introduces Hangul (한글), the Korean alphabet: https://tolearnkorean.com/

Also making an app / web app for memorizing Korean words, takes inspiration from Anki and Duolingo. Words go through 4 stages: 1) matching up pairs 2) Multiple choice answer 3) Writing word through blocks 4) Free-form writing.
