Duolingo

Gamified language learning app: 40+ languages available, short daily lessons, motivated by a mascot and streaks

Education

Overview

Duolingo is a gamified language learning platform teaching 40+ languages (English, Spanish, French, German, Chinese, Japanese, etc.). Lessons are short (5-10 minutes), daily and designed for retention via spaced repetition. The app uses a points system, streaks (consecutive learning days) and a mascot (Duo the owl) to motivate users. The free plan includes access to all lessons with ads and daily limits. Super Duolingo ($12.99/month or $84/year) removes ads, offers unlimited lessons and a daily challenge where users don't lose their streak on mistakes. A family plan ($119.99/year) shares the subscription across 6 accounts.

Duolingo is available in French (French is one of 40+ languages offered for learning). No documented public API for developers. The tool has reached over 500 million downloads and remains very popular for informal language learning. Duolingo recently added interactive stories, podcasts and live events to vary formats. However, educational critics note that Duolingo doesn't replace a traditional course or tutor: the gamified approach sacrifices depth for engagement. To achieve real language fluency, users should combine Duolingo with other resources (conversation, immersion, more formal courses).

Our verdict

Best for all individuals and students wanting to learn a language at their own pace without heavy commitment, with zero entry cost. Not for you as the only tool for professional needs or real language mastery: the app lacks depth for achieving fluency.
