Ratings and reviews

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.

I just updated the app to the latest version and it has failed to open after multiple attempts to open the app. I ask that this be rectified as soon as possible for I do not want to miss my classes and disrupt my progress so far. Thank you.

The app was working perfectly fine before the update. Since updating, it stays on the loading screen for almost two minutes and then crashes. After that, it won’t open again.
