How we picked

We judge language tools the way a learner actually experiences them: how well they teach grammar and real conversation, how deep the courses go, how they handle review and retention, what they cost, and how many languages they support. We also separate two different jobs — self-study apps that build a foundation, and tutoring platforms that get you speaking — because the best setup for most people uses one of each. Nothing here is ranked by what pays us; affiliate relationships never move a tool up our list.

The best language learning apps at a glance

1. Babbel — best overall app

Babbel is our top pick for most adults. Its 10-to-15-minute lessons are built around real conversation, grammar is explained clearly rather than left to guesswork, and a spaced-repetition review system makes the vocabulary stick. It covers 13 languages and goes deep on the major ones — Spanish, French, German, Italian. At roughly $8.95 a month on an annual plan (with a frequently discounted Lifetime option), it is excellent value. It will not make you fluent alone, and its smaller-language courses are thinner, but for structured self-study it is the best app available. Read our full Babbel review or try the first lesson free.

2. Duolingo — best free app

If you want to spend nothing, Duolingo is the clear winner. Its gamified streaks, leagues, and points make daily practice genuinely fun, and it teaches more than 30 languages, including rarer ones other apps skip. The trade-off is depth: grammar is light and you learn largely by pattern, so it is better for habit-building and vocabulary than for serious conversation. Many learners use it free forever; the optional Super tier (~$7.99–$12.99/month) just removes ads. See how it stacks up in our Babbel vs Duolingo comparison.

3. Pimsleur — best for audio and speaking

If you learn best by listening — in the car, on a run, doing chores — Pimsleur is the standout. Its audio-first, 30-minute lessons drill pronunciation and recall harder than any screen-based app, and they train your ear and mouth in a way Babbel and Duolingo do not. It is pricier (around $15–$21/month) and lighter on reading and writing, but for accent and spoken confidence it is hard to beat. Read our Pimsleur review or try Pimsleur.

4. italki — best for flexible tutoring

No app replaces talking to a person, and italki is the most flexible, affordable way to do that. It connects you with tutors in 150+ languages on a pay-as-you-go basis — no subscription — with rates often near $10 an hour. You can mix credentialed professional teachers for structure with cheaper community tutors for conversation. It is our top pick for getting past the app plateau.

5. Preply — best for structured tutoring

Preply is the other major tutoring marketplace, with a huge, well-vetted pool across 90+ languages. The key difference from italki is structure: Preply sells a recurring weekly lesson package rather than single lessons, which keeps less disciplined learners consistent. Rates start a little higher (~$15–$30+/hour), and a happiness guarantee protects your first lesson. Choose it if a fixed schedule helps you show up. Read our Preply review or find a tutor.

6. Lingoda — best for live online classes

If you want the structure of a real class with a teacher and a set curriculum — but online — Lingoda is the pick. It offers small live group classes and private lessons in English, Spanish, French, and German, with a clear level system and certificates. It is more of a commitment than a casual app, and pricing runs around $8–$16 per class depending on your bundle, but the live-teacher accountability is excellent for steady progress.

7. Rosetta Stone — best for immersion

Rosetta Stone is the original immersion app: it teaches with images and target-language audio only, no English translation, to build intuition the way children learn. Some learners love the method; others find the lack of explanation frustrating, especially for grammar. It covers around 25 languages and is often sold as a subscription (~$12/month) or a lifetime bundle. Worth a look if immersion appeals, though it is no longer our default recommendation. (We have no affiliate relationship with Rosetta Stone; it is here purely on merit.)

8. Busuu — best freemium alternative

Busuu sits between Duolingo and Babbel: a freemium app with structured courses, AI-guided review, and a community feature where native speakers correct your writing and speaking. The free tier is usable, and the paid plans (~$6–$14/month) unlock the full course path. It supports fewer languages (around 14) but the native-speaker feedback loop is a genuine strength. A solid alternative if Babbel and Duolingo do not fit. (No affiliate relationship; listed on merit.)

How to choose the right app for you

Match the tool to your goal. Want a free daily habit? Start with Duolingo. Want structured lessons and grammar in a major language? Babbel. Learn best by ear, or want a better accent? Pimsleur. Ready to actually speak? Book a tutor on italki or Preply. Prefer the accountability of a live class? Lingoda. And the most effective approach for most serious learners is a combination: a self-study app for daily foundations plus a weekly tutor session for real conversation. One builds the knowledge; the other turns it into speech.

Do language apps actually work?

Yes, within limits. A good app reliably builds vocabulary, grammar, and comprehension, and the daily habit it encourages is genuinely valuable — consistency matters more than any single feature. What no app does well on its own is produce conversational fluency, because real conversation is unpredictable in a way scripted lessons are not. Treat an app as the foundation, not the whole house: pair it with regular speaking practice — a tutor, a language exchange, or time in the country — and the combination works.

Frequently asked questions

What is the best app to learn a language?

For most adults, Babbel is the best overall app — structured, grammar-aware, and affordable. Duolingo is the best free option, and Pimsleur is best if you learn by listening. To actually speak, add a tutor on italki or Preply.

What is the best free language learning app?

Duolingo, comfortably. Its free tier is genuinely usable long-term, it teaches 30+ languages, and the gamification keeps you coming back. Busuu’s free tier is a good secondary option.

Which app makes you fluent?

None on its own. Apps build a strong foundation (typically up to an intermediate level), but conversational fluency requires real speaking practice. The fastest route is an app plus regular tutor sessions on italki or Preply.

What is the best app to learn Spanish or French?

Babbel is especially strong for Spanish, French, German, and Italian — its flagship courses are the deepest. Pair it with a tutor for conversation, and you have the most effective setup for those languages.
