Duolingo Korean vs Duolingo French Course
Same Bayesian formula, same rubric — so the difference in scores reflects the difference in the courses, not the difference in how we evaluated them.

Per-criterion
The Hangul onboarding is the strongest part — the 24 letters are introduced gradually inside real words, and most reviewers can read basic Hangul within a week or two. Beyond that, the Korean tree is noticeably smaller and less developed than Spanish: roughly 65 skills over three checkpoints, topping out around TOPIK Level 2 (CEFR A2). Particles, conjugation, and the honorific system — the things that make Korean hard — are presented as patterns to absorb rather than concepts to understand.
There is no instructor; the method is implicit pattern-matching. For a SOV language with particles and multiple politeness levels, the hands-off approach is a real weakness. Reviewers note the course throws sentences at you and expects you to induce the rules, and that speech levels like formal-polite and polite appear at random without explaining which to use. Korean's grammar diverges far more from English than Spanish does, so the lack of explanation bites harder here.
The entire Korean course is free, which is its clearest strength — zero-cost Hangul exposure and basic vocabulary with no commitment. Super Duolingo (~$7-13/month) removes ads and adds hearts but does not fill the structural gaps, so reviewers agree the value lives almost entirely in the free tier. The unpaid experience is heavily ad-interrupted, which several Korean learners called out as frustrating, but the price-to-content ratio at zero is still favourable for a beginner.
The streak engine, XP, and reminders work as well for Korean as for any other course — they build a genuine daily habit and are the most common reason reviewers credit Duolingo with keeping them studying at all. The smaller Korean tree means motivated learners reach the end of meaningful content faster than in Spanish, and the well-documented A2 plateau arrives sooner, where recognition keeps improving but real ability stalls.
Duolingo support is email-only, slow, and community-forum-led, and the Korean course has less external community coverage than the flagship European languages. Billing, streak-recovery, and account issues are the usual pain points. The smaller learner base means fewer third-party explainers to fall back on when the in-app notes are thin.
This is the weakest area, and Korean exposes it sharply. Speech exercises use unreliable voice recognition, there is no spontaneous production, and the honorific system that governs almost every real Korean interaction is barely explained. Multiple reviewers describe studying Korean on Duolingo for a year and being unable to do more than greet a native speaker. It builds receptive vocabulary, not conversational ability.
The French course now extends to upper-intermediate (B2) following a December 2025 expansion, and recent updates added more conversational dialogues and grammar tips. Vocabulary coverage is broad and the Stories feature adds useful context. But grammar is taught primarily through implicit pattern-matching rather than explanation, and reviewers flag a high proportion of impractical sentences in early levels.
There is no instructor. The method is gamified implicit learning — learners recognise patterns through repetition rather than being taught rules. For French beginners who primarily need vocabulary and exposure, the method works; for learners who need to understand French syntax and grammar logic, the absence of explanation is the app's central pedagogical weakness.
The core course is genuinely free, making it the best zero-cost entry point to French learning available. Duolingo Super (~$7/month) removes ads and adds unlimited hearts; reviewers largely agree this subscription does not fix the structural gaps, so the free tier is where most of the value sits.
The streak system, daily reminders, XP leagues and personalised characters make Duolingo the most habit-forming language app available. Multiple reviewers report using it every day for years. The gamification that some critics find shallow is the exact feature that keeps learners coming back when other apps do not.
This is the course's most consistent weakness. Reviewers across multiple sources agree that Duolingo teaches recognition, not production. Learners can read and recognise French reasonably well but struggle to speak it. Pronunciation feedback accepts rough output; native speakers speak faster and more connected than the app ever models; and conversation practice is not a feature.
