I love this app, its definitely helps facilitates my independent study of Korean on the go! The only negative thing I have to say is the fact that all podcasts are listed in chronological order makes it becomes a bit confusing and time consuming to look for a specific podcast and lesson. It would be much easier if all audio files were listed according to its category in chronological order (such as 이야기, Ask HyoJin, Level [ ] Lesson [ ], Korean Drama Phrases, etc).
