Ratings and reviews

I had this app before it was 2.0. But when I checked it after the update, I was really surprised by how well this app is. starting from checking the attendance, to syncing with the material on the website. It's exactly what I needed. I also loved the pronunciation checker. It has a very clean UI and easy to interact with. one thing that needs to be considered is when being idle for a couple minutes, it says lost connection, and I lose my time counter. Other than that, it's my favorite!

I’ve really enjoyed using the King Sejong Institute Korean Learning App. The lessons are clear and well-structured, and the app does a good job of combining vocabulary, grammar, and listening practice in a way that’s easy to follow. The audio is clear, and I like that it also introduces aspects of Korean culture. It’s a helpful app for anyone learning Korean, especially if you want a more structured approach.

Learning Korean with the Learn Korean with Mobile KSI has been a very helpful experience for me. The app offers well-organized lessons that make Korean easier to understand, even for beginners. I especially like the clear explanations of grammar and the useful vocabulary practice. The exercises are interactive and allow learners to review what they have learned step by step. Another great feature is that the lessons also introduce Korean culture, which makes learning more interesting.
