Duolingo
Duolingo is the easiest way to build a daily language-learning habit for free, though it won't get you to full fluency on its own.
Duolingo covers 40+ languages, including some less commonly taught ones, though course depth trails dedicated language schools.
The gamified, bite-sized format is excellent for building a daily habit and vocabulary, but conversational fluency needs supplementing with real practice.
The app is exceptionally polished, playful, and habit-forming — arguably the best-designed app in this category.
The core app is genuinely free forever; Super ($6.99/mo billed annually) removes ads and adds offline lessons and unlimited mistakes.
The language learning app does not award a formal course qualification. The Duolingo English Test is a separate assessment with its own requirements and fees.
Duolingo is mobile-first, with Super subscribers getting full offline lesson access.

Who should consider Duolingo?
Duolingo focuses on short, game-like language learning lessons. It is worth considering for beginners building a consistent language-learning habit. The official platform website provides current programme and access information.
Build a realistic learning plan
Set a practical language goal, such as understanding simple travel questions or introducing yourself. Treat daily lessons as one part of that plan. The best schedule is one you can maintain without allowing points or streaks to distract from actual comprehension.
Turn lessons into practical progress
Use new vocabulary in sentences of your own and practise saying them aloud. Add listening material suitable for your level and revisit words outside their familiar exercise context. As confidence develops, include conversation so recognition becomes an ability to communicate.
What learners in Europe should check
Check the course available for your native language, since language pairs can differ in content. If you choose a paid option, inspect the features and billing period shown to your account. For work or formal study, separately confirm which language assessment is required.
Review your progress before continuing
Set a small milestone before starting another course or lesson series. Record what you can now do independently, which questions remain and what you want to practise next. This gives your next learning decision a clear purpose rather than simply adding more content to your queue.
