9 real-life topics and 4 levels, from your very first words to easy conversation at native speed. Just choose your language the first time you open the app, and you’re in the Korean course.
Talk with a university-student friend, a barista, a restaurant owner, a taxi driver and more.
Talk with a real estate agent, your landlord, a doctor and a pharmacist.
Talk with a Korean teacher, a professor, your part-time boss and your team lead.
Particles, verb endings, knowing when to be polite — Langer explains the trickiest parts of Korean in plain English.
Have a live voice conversation with a barista, a landlord, a professor and more — each with their own personality and way of speaking.
See a more natural way to say each line, and why: particles like 은/는 and 이/가, verb endings, and when to use 존댓말 or 반말.
After each conversation, look back at what you said and the lines worth fixing, and hear the more natural version read aloud.
None of the things that bug you in other apps.
