Ratings and reviews

Absolutely horrendous bugs/tech issues. I had their previous app and it was way less glitchy than this. It didn't recognize my old account so I had to create a new one. I had to use Google Translate to understand how to create an account and accept the terms and conditions since it was all in Korean!! Then, the password I created didn't work and the email they sent me for a temporary password was glitchy as well. Then once I tried to sign in, I just had a blank white screen. 0 stars, please fix!

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

I loved the app! I was too lazy to study from the book, so I downloaded this, and it helped me a lot. It's not perfect for sure, I think you should add features like: saving grammar, ability to see the example sentences of saved words, and maybe flashcards reviewing for the words! Thank you for all.
