Duolingo French Course vs Babbel English
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 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.
The English course is built by linguists and scaffolds grammar into real-life dialogues — ordering, travel, work, meeting people. Reviewers consistently call the curriculum clear, progressive and conversation-first. The main gap is that material thins out and feels repetitive once you pass A2/B1.
No live teacher — Babbel's method is the "instructor". Direct grammar explanations and scaffolded dialogues are widely described as feeling "designed by language instructors" rather than statisticians. Strong for self-learners, but there is no one-on-one correction in the base product.
At roughly $8-15/month (cheaper on longer plans, with a lifetime option) it is solid value for structured learning, and EU funding historically kept it competitive. The drag is the lack of any permanent free tier versus Duolingo, and a curriculum that plateaus after you finish your language's tree.
Short, varied 10-15 minute lessons and frequent review keep daily practice sticky for adults who dislike streak pressure. The flip side, noted repeatedly, is that with no gamification you must "bring your own motivation" — some learners quietly drift off.
Standard email/help-centre support for the app; no live tutor in the base subscription. Live conversation and teacher feedback sit behind the separate Babbel Live tier (around $99/month). For the core English app, support is adequate but not a standout.
Dialogues teach English you would actually use and build early speaking confidence, and the formal/business slant suits work and travel. But speech recognition only gives pass/fail feedback and there is little genuine conversation, so the app alone won't get you to natural casual fluency.
