I highly recommend this application. It's an excellent tool for learning Korean language. The app is easy to use and provides a comprehensive range of lessons and activities. But the one only problem is little bit annoying. In the Vocabulary section, It doesn't record my voice at all sometimes. Overall the best app I've used.

The intention is good, but it needs more polishing. It is not very intuitive or user friendly. I would look towards the Super Chinese app for improvement opportunities, especially in the layout and on the grading of what syllables are pronounced correctly, and in exercising the use of core vocabulary both as lesrning the word on its own but also on context.
