It helps a lot and it really good. They have a lot of phrases and practice to help you write and speak Korean and read also.
Even though some stuff is a pro version, just click on the watch an ad for free trial and you actually dont even watch an ad, you just see the ad for a second and exit out, then it lets you see the pro version of it for as long as you want.
The only thing is that when you go into another pro version subject, the one that you were in before, is still locked so you have to watch an ad again to get the free trial but it only takes a second or a minute.
All in all, its a really good app! I love it and I think its really helpful.
