유지할까요, 더 늘려볼까요?

Maintain your Korean, or improve how you speak.

Free is a weekly check-in. Lite gives confident speakers a daily conversation habit. Plus adds unlimited conversations and deliberate pronunciation practice.

What actually changes

The companion, three-minute format, topics, difficulty, speech style, recordings, recaps, web grounding, and whole-conversation scoring stay the same.

The difference, on screen

The current iOS screens show the two ends of the experience. Lite follows Plus through grammar review and example audio, then stops before jamo diagnosis and recording practice.

Call or roleplay when you want

Free gives you one complete phone call or roleplay each week. Lite gives you one every day. Plus removes the count limit; all three keep the same focused 3-minute format.
