Amazing!

Such an easy-to-use app that has been useful for me in so many different conversations, a must use for anyone learning or relearning Korean!

Not special...

The vocabulary feels very random, and some sentences are creepy lol. It’s also very confusing — there are too many menus and all the languages are mixed together. It’s hard to focus and read on my phone. I’m an intermediate Korean learner, but the sentences feel very childish. The flashcards are basically just the Anki system, so it doesn’t feel new or special. Also, the ads and overall style feel very similar to every other language-learning app.

OMG He added pinyin and jyutping for full complete hanja words !

I will gladly pay high monthly fee if you can add pinyin and jyutping for full complete hanja words. UPDATE: Benjamin, you are a godsent , you actually added Cantonese Jyutping, this is such a game changer for studying CJK language studies in one single app. I’ve been looking for an app like this for well over 10 years. I am so much in your debt ! Guys download this app to revolutionize your CJK Language studies . This developer put in a the bells and whistles that no developer comes close to in a CJK app
