Speak real-life Korean, one scene a day. Koppa gives you one real Korean scene every day: ordering at a café, catching the last train, meeting your partner's parents. You learn what people actually say in that moment, then you say it yourself. MEET YOUR TUTOR Your Korean tutor has a personality straight out of a K-drama. He walks you through every scene line by line, listens as you speak, and celebrates with you when you get it. Easy for complete beginners: every lesson starts from zero, so your first day needs no Korean at all. ONE SCENE A DAY • Understand: every line explained, so you know what it means, how it's built, and when to say it. New to hangul? Romanization is one tap away. • Speak: say every line out loud and polish your Korean pronunciation. • Rehearse: put the conversation back together and talk your way through the whole scene. • Casual: say the scene again the casual way, the Korean you hear in dramas and between friends. PRACTICE OUT LOUD • A course of everyday Korean phrases, grouped by situation: at the airport, at the bank, ordering coffee, making friends. • Say each phrase out loud and get a score with word-by-word notes, so you know which word to work on next. • Short rounds, and your best recording kept for every phrase, so a few minutes still moves you forward. Made for K-drama and K-pop fans, for your next trip to Korea, and for anyone who wants to say a Korean sentence out loud and know it landed. KEEP WHAT YOU LEARN • Every word you meet is saved to your vocabulary list, free, to review anytime. • Build a daily streak, one scene at a time. GO DEEPER WITH KOPPA PREMIUM • Speaking practice on every phrase in the course, after the free phrases you start with. • Missed-day review, so a busy week doesn't cost you your progress. Whether you want to learn Korean for a trip to Seoul, follow a K-drama without subtitles, sing along to K-pop, or talk with someone you love, Koppa teaches Korean conversation you'll actually use.

Verdict
The clearest difference is in-app purchases: Yapper at none against Koppa's 16. Yapper also leads on rating (5.0 vs 4.8) and update cadence (every 2 days vs every 5 days). Koppa's advantage is ratings volume (330 vs 8) and iOS requirement (15.0 vs 17.0). On price, ads and device support there is nothing between them.

Both are free to download. Koppa sells 14 in-app purchases, starting at $2.99 per 7 days. Yapper asks for nothing beyond the download.
Yapper holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Koppa has 330 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 88% of Koppa's written reviews are positive against 100% of Yapper's.
Koppa ships an update every 5 days, Yapper every 2 days. The most recent releases landed on September 28, 2026 and June 1, 2026 respectively.
