Amazing !!
Im a beginner and i honestly find this app great :)). However there are ads between each lesson, but not those annoying "sign up for premium!" ads. The ads are only about 30 seconds long each so i dont really pay any attention to them. Also when you tap to get premium a pop up comes up and says something along the lines as "Please dont sign up for premium, premium is only for serious korean learners. This app has a bunch of free lessons" which i think is pretty true! Although i didn't get premium, the free lessons (with the ads in between) explain really throughly and make understanding the characters and grammar really easy. So in conclusion, if you're a beginner and are okay with ads then you should get this app!
