Duolingo, Babbel, Busuu and Memrise compared — gamified daily drills, conversation-first lessons, native-speaker corrections and real-speaker video for any study style.
A few minutes a day on your phone is enough to make real progress in a language, but only if the method fits how you actually study. These four apps take genuinely different routes: one turns drills into a streak-driven game, one builds lessons around speaking from the first session, one pairs courses with feedback from natives, and one teaches through video of real speakers. Choosing badly is usually why people quit, not laziness — a grammar fan will dislike a pure game, and a conversation-first learner will abandon slow vocabulary drills. The 4 apps in this guide were selected for the four study styles they cover, from complete beginner to someone brushing up a language.
Duolingo is the biggest name in language apps: 40-plus languages, five-minute gamified lessons and one of the most generous free tiers available.
Duolingo turned language study into a daily game and remains the easiest way to build a habit: short five-minute lessons, streaks, levels and rewards push you through more than 40 languages without feeling like coursework. The free version is genuinely complete, which makes it the obvious starting point for beginners and a low-effort way to keep a language alive between trips. Its weakness is the same thing that makes it addictive — the drills are shallow. Real conversation gets less attention than in Babbel, the free app shows ads, and going ad-free means paying for Duolingo Super. Treat it as the habit engine, not the whole curriculum.
Babbel teaches around real conversations designed by linguists, for anyone who wants to speak in everyday situations as quickly as possible.
Babbel is built around one promise: you speak from the very first lesson. Its linguist-designed courses use everyday situations — ordering food, introducing yourself, handling work calls — instead of isolated word lists, and speech recognition checks your pronunciation as you go. Compared with Duolingo, the structure feels more like a real course and less like a game, which suits learners whose goal is using the language soon rather than keeping a streak alive. The trade-offs are straightforward: full access requires a subscription, the catalogue covers fewer languages than Duolingo, and the sober presentation simply hooks some people less than points and leaderboards do.
Busuu combines full structured courses with native speakers correcting your exercises, plus study plans and certificates for serious learners.
Busuu sits between a traditional course and an exchange app: structured lessons cover grammar, vocabulary and conversation in sequence, while a community of native speakers corrects the exercises you submit. Personalised study plans give the path a target, and official certificates make the progress tangible for anyone learning for work or study. The appeal is seriousness with feedback baked in — you are not relying on chance encounters to practise. As with the other course apps, the free layer is a taster: Premium unlocks the strongest material, there are fewer languages than on Duolingo, and how useful the community is tracks how active its members are that week.
Memrise teaches through video of real native speakers and spaced repetition, for vocabulary and an ear for the language as people actually speak it.
Memrise's differentiator is footage of ordinary native speakers, so vocabulary arrives attached to real faces, accents and expressions rather than synthetic audio. A spaced-repetition system decides when each word reappears, which helps new terms stick long term, and the material leans heavily on the language as it is actually spoken outside textbooks. It is the best pick here for widening your vocabulary and training your ear to authentic pronunciation. What it is not is a grammar course: structure is lighter than in Babbel or Busuu, writing practice gets less attention, and the full catalogue sits behind a subscription. Pair it with something more structural if exams are the goal.

Questions & answers
What is the best free language learning app?
Duolingo. Its no-cost tier is genuinely complete, covers more than 40 languages and funds itself with ads rather than locking away core lessons. Babbel, Busuu and Memrise offer much thinner free versions and reserve their strongest material for subscribers. If the goal is starting a language without spending anything, Duolingo is the sensible default; the others are worth paying for only once you know which method keeps you studying.
Duolingo or Babbel — which should you pick?
It depends on your goal. Duolingo wins for starting out and protecting the habit: free, addictive and broad, but shallow in real conversation. Babbel wins if you want to speak soon in real situations, with more structure and linguist-built lessons, but it requires a subscription. Plenty of learners run both: Duolingo for the daily streak, Babbel in parallel to go deeper into speaking.
Can you learn a language with an app alone?
An app is excellent for vocabulary, grammar and daily contact, but fluency also needs real conversation — exchange partners, natives or paid lessons. Busuu narrows that gap by building native-speaker corrections into a course, but eventually you still have to speak to another human. The bigger predictor is regularity: a few minutes daily beats an occasional long session, so choose the app you can imagine opening tomorrow, not the one with the most features.
