Very Good

It’s one of the better apps that I’ve ever come across. It challenges me and forces me to stretch my limits. My only complaint is that, and this won’t impact everyone, is that the font is so tiny and the screen blocks the zoom function. I quit feeling eye strain more nights than not. If they ever increase font size or restore zoom functionality, I’ll add the fifth star. UPDATE: the developer quickly added support for text sizing. Amazing support for a fantastic app! 감사함니다!

Updated Review

Editing: Thank you to the developers for listening! This app is do great and the changes have made it much easier to understand! The translations can be too complex at times: for example “It's not complicated, it's easy and simple. It's not hard, so you can do it in no time.” - I know based on the example it means quick but its a little hard to understand what the word means.
