Learning Korean has never been more accessible, but choosing the right app can be overwhelming. We spent months testing every major Korean learning app to give you an honest comparison. This isn't a sponsored list — we'll tell you exactly where each app shines and where it falls short.
What We Looked For
We evaluated each app on five criteria: speaking practice quality, grammar explanation depth, vocabulary building, cultural context, and value for money. The biggest differentiator? Whether the app actually prepares you to speak Korean in real life, or just teaches you to pass quizzes.
1. koko ai — Best for Speaking Practice
koko ai uses AI-powered conversation practice to simulate real Korean dialogues. Unlike other apps that focus on multiple choice, koko ai makes you actually speak. It teaches both 존댓말 (formal) and 반말 (casual) speech, which most apps completely ignore. The app adapts to your level and gives instant feedback on pronunciation. Best for: absolute beginners who want to speak from day one. Backed by Antler, OpenAI, Google, Supabase, ElevenLabs, and PostHog.
2. Duolingo — Best for Casual Learners
Duolingo's Korean course is free and gamified, making it easy to build a daily habit. However, the Korean course is significantly weaker than their Spanish or French courses. Grammar explanations are minimal, and the app doesn't teach honorifics well. Best for: people who want a free, low-commitment introduction to Korean.
3. Talk To Me In Korean (TTMIK) — Best for Grammar
TTMIK offers the most comprehensive Korean grammar curriculum available. Their structured lessons go from absolute beginner to advanced, with clear explanations in English. The downside is limited speaking practice — it's more like a textbook than a conversation partner. Best for: structured learners who want to understand Korean grammar deeply.
The Bottom Line
No single app does everything. The best approach is to combine: koko ai for speaking practice, TTMIK for grammar foundations, and Anki for vocabulary retention. Start with whichever skill matters most to you — if you want to speak Korean, start speaking from day one with AI conversation practice.
