Ratings and reviews

Thank you very much for this wonderful application. I really need this practice in speaking and pronunciation, so that it is difficult for me to speak rather than write. Listening and speaking are the best tools to communicate with anyone, anywhere. I am keen to further my Korean language journey so that I can open up more opportunities. I will always practice learning the Korean language using this excellent application and enjoy an innovative way that will definitely help me reach the desired

It's not bad, but the AI voice recognition, or whatever they're using seems very poor. 가영 was detected as 과연 지영(?? they're not even close) 가응 all over the place, and yet every other word in the sentence was fine. I know I wasn't saying it incorrectly. I've noticed a particular issue in this with all the speaking sections I've done so far.

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!
