VeryWord - Korean Vocabulary 4+

I like this app especially because it has the vocabulary nicely categorised into nouns, verbs, adjectives etc. I also appreciate that the vocabulary is grouped into TOPIK Basic, Intermediate & Advance, as well as “Most Common Words”. The different categories & groupings of words is super helpful! One of the best things about this app is an in-built dictionary, which means I don’t have to exit the app to search for the meaning of a word. However, I’m at a loss as to how to mark words as “reviewed”. I’m not sure if it’s something that’s supposed to happen automatically, because there’s no option to select a word as reviewed. If there isn’t a way to do this, then perhaps that’s son that can be added. To be honest, I’m not entirely clear on how to use this app and there’s not much explanation on here or in the app itself. Perhaps it’s only function is to have all the TOPIK vocabulary in one place, which it has done very well. And if that’s the case then so be it, however, I was under the impression that there’d be spaced repetition options & ways to test your learning. Either way, it’s a great app & itself free so can’t complain. I’ll still continue using it anyway, even without the bells & whistles!

The Korean flashcard app of my dreams, the only things I wish it had to make it absolutely perfect would be audio and a way to reorder collections. But those are just small nitpicks, everything else is what I’ve been looking for for YEARS

Love the app and the idea of a quick review and training all necessary words for TOPIK. But I can't add collection and practice words, because of the constant error “Something unexpected happened”. It doesn't let me through. I’ve tryed everything, but have the same thing all the time. Can it be fixed?
Thanks!
