The Rundown

  • Our favorite language learning apps are the Babbel and the Duolingo.
  • Babbel excels with structured, conversation-first lessons and AI practice, while Duolingo provides a free, gamified, and accessible way to build a language-learning habit.
  • Choosing the right app depends on your learning style, budget, and goals, as no single app alone will lead to full fluency without real-world practice.

Learning a new language has never been more accessible. You no longer need a classroom, a stack of textbooks, or a shelf of old CD-ROMs—just a phone and a few spare minutes a day. But that accessibility comes with a catch: There are dozens of apps competing for your attention (and your subscription dollars), and they all take wildly different approaches to teaching you another language.

Some, like Duolingo, turn learning into a game you'll want to open every day. Others, like Babbel and Pimsleur, focus on real conversation and how adults retain a language. A few lean on immersion, native-speaker video, or even augmented reality. The right pick depends entirely on how you like to learn, how far you want to go, and how much you're willing to spend.

We've reviewed these apps individually for years—using Babbel for more than two years, spending a year inside Duolingo, and putting Pimsleur, Rosetta Stone, and Mondly through their paces.

This guide pulls that experience together and rounds it out with the other major players worth knowing about. Our top pick, Babbel (available at Babbel.com), earns Best Overall for its structured, conversation-first lessons that graduate you toward real-world speaking. If you're not ready to pay, Duolingo (available on the iOS and Android app stores) is the best free place to start.

Best Language Learning App
Babbel
  • Cost: From $8.97/month (12-month plan); lifetime subscription around $299.99
  • Languages: 14, including Spanish, French, German, Italian, and Portuguese
  • Method: Conversation-first lessons, native-speaker audio, spaced repetition, AI conversation partner
  • Skill levels: Beginner through advanced (CEFR A1–B2)

Babbel is the best language-learning app for most people because it does the one thing casual apps often skip. It teaches you to hold a conversation. From the very first lesson, you learn practical, real-world phrases—how to introduce yourself, talk about your family, and order food—rather than a random list of colors and animals.

We used Babbel for more than two years, and in our testing, three things stood out.

  1. Babbel incorporates real-life conversational topics
  2. Native speakers record the audio
  3. Babbel uses spaced repetition that resurfaces each new word so it sticks

Recent AI additions, including a conversation partner you can practice speaking with, have made it stronger still, and they don't cost extra.

For our review, we also consulted Dr. Esther Gutierrez Eugenio, a language-learning expert with a PhD in Language Education, who notes that apps like Babbel are especially useful for practicing in a low-pressure environment before you take the language into the real world.

Pricing is subscription-based, starting at around $8.97 per month on a 12-month plan and up to $15.25 per month on a month-to-month plan. There's also a lifetime option that runs about $299.99, and it often goes on sale through third-party vendors.

The biggest knock against Babbel is the price. The other limitation is that its courses top out at the B2 (upper-intermediate) level so that it won't carry you to full fluency on its own—for that, you'll still need real-world immersion and conversation. But for building a genuine, usable foundation in a language, it's the app we'd hand almost anyone.

Pros

  • Conversation-first lessons build real speech

  • Native-speaker audio and spaced repetition

  • Free AI conversation partner

Cons

  • Requires a paid subscription

  • Courses stop at B2 level

Best Value Language Learning App
Duolingo
  • Cost: Free; Super Duolingo around $12.99/month, though prices vary by region
  • Languages: 40, including Spanish, French, Japanese, Welsh, Navajo, and Klingon
  • Method: Gamified bite-sized lessons, streaks, leaderboards, stories
  • Skill levels: Beginner up to B2 on popular courses

Nothing beats free, and Duolingo remains the best free language-learning app you can download. In our testing, its greatest strength was how effortlessly it removed the intimidation of getting started.

Within minutes of installing the app, you're taking your first lesson. Every language course is fully accessible at no cost, and the app's famous gamification—daily streaks, XP, leagues, and the guilt-tripping green owl—is effective at keeping you coming back.

We used Duolingo for about a year and found it excellent for building a habit and picking up conversational vocabulary. It's also backed by research. A University of Toronto study found that learners who completed Duolingo's A2 courses scored above that level on standardized tests. With 40 languages ranging from Spanish and Japanese to Navajo and even Klingon, few competitors match its range.

The trade-offs show up if your goal is full fluency. In our experience, lessons rarely stop to formally explain grammar or verb conjugations, leaving us to rely on the Guidebook and translations to fill in the gaps.

Free users are also capped at five mistakes per day and shut out of the app's best speaking and conversation practice tools, which sit behind the Super Duolingo paywall.

If you do want to upgrade your account to Super Duolingo, it's hard to know exactly how much you'll pay. The Duolingo website doesn't list a set price, and even the app hides the real price until you've finished a limited free trial. That's not a ding against the content of the paid tier, but it is frustrating if you want to know what you're getting into.

Still, for a free app that gets you started in minutes, there's no better on-ramp to language learning.

Best Audio-Based Language Learning App
Pimsleur
  • Cost: From around $20.95/month (Premium)
  • Languages: 50-plus, with 200-plus courses across dialects
  • Method: Audio-first, 30-minute daily lessons, conversation-based, minimal screen time
  • Skill levels: Beginner through intermediate

If you learn best by listening, or you want to study while you cook, drive, or walk, Pimsleur is the best audio-based language app we've tried.

Founded by Dr. Paul Pimsleur and on the market in various forms since 1963, Pimsleur centers on 30-minute daily audio lessons that teach through conversation and repetition, with almost no need to look at your screen.

In our testing, the audio-first method forced us to retain vocabulary rather than recognize words on a page. Pimsleur introduces each new word by sound, breaks tricky ones down syllable by syllable, and blends old and new vocabulary into every lesson so it accumulates naturally.

We found it especially strong at building the confidence to speak. You practice pronunciation in private, at your own pace, until the language's sound system starts to feel natural. This approach is a close cousin of the acclaimed Michel Thomas method, so if that one appeals to you, Pimsleur likely will too.

The downside is the price. Premium subscriptions cost about $20.95 per month, and the plans offer little flexibility if you're planning a trip or a big event. But for pure spoken-language pedagogy, it's remarkably effective.

Pros

  • Audio-first, ideal for hands-free study

  • Builds speaking confidence and retention

  • 50-plus languages available

Cons

  • Expensive versus app-based rivals

  • Fixed pace with little flexibility

Best Language Learning App for Immersion
Rosetta Stone
  • Cost: Lifetime access frequently on sale around $149–$199 (MSRP about $399)
  • Languages: 25
  • Method: Image-based immersion, TruAccent speech recognition, minimal translation
  • Skill levels: Beginner through advanced

Rosetta Stone has been around for years. The company practically invented at-home language learning, and its immersion-first approach still holds up today. Instead of relying on direct, rote translation, the program pairs words and phrases with images so you absorb the language the way you learned your first one, by association rather than memorization.

In our testing, we were impressed by how quickly it moved. Within a few days, it had introduced dozens of nouns and a range of verbs, and we came away with a deeper grasp of grammar and conjugation than a free app like Duolingo gave us.

The best thing Rosetta Stone has going for it has to be TruAccent, a patented speech-recognition engine that grades your pronunciation and lets you set how strictly it judges you. That extra control helps if you want to sound closer to a native speaker. Some plans also include live tutoring sessions with native speakers, which is a real advantage when you want to practice out loud.

Two caveats stand out. In our testing, the interface felt dated next to modern apps, and the speech recognition occasionally flagged correct single syllables as wrong. And while a lifetime subscription (frequently discounted to around $149–$199) can be strong long-term value, the sticker price is steep.

If you want a structured, immersion-based program and plan to stick with it, though, Rosetta Stone earns its reputation.

Pros

  • Immersive, image-based method

  • TruAccent pronunciation feedback

  • Live tutoring on some plans

Cons

  • Interface feels dated

  • Speech recognition can be finicky

Other language-learning apps we tested and evaluated

Product image of Mondly
Mondly

Mondly is a gamified app much like Duolingo, but with a few twists of its own. In our testing, its best feature was a chatbox that records your voice to build a full scripted conversation, then plays it back so you can hear yourself speak.

We found that playback smoother and more natural-sounding than some rivals. You can also learn from any of its 41 base languages, so it works well for non-English speakers and polyglots, and it includes an augmented-reality mode that projects a virtual teacher and objects into your room.

The AR mode splits people sharply, and we landed firmly on the unsettling side. Like most gamified apps, Mondly works better as a vocabulary supplement than a route to fluency.

Pricing starts with a free tier, and a single-language Premium plan runs around $9.99 per month or $61.92 per year ($154.80 MSRP).

Read our full Mondly review.

Pros

  • Unique voice-recording chatbox

  • Learn through any of 41 base languages

  • Free tier to try it out

Cons

  • AR feature won't be for everyone

  • Better as a supplement than a course

Busuu

Busuu's defining feature is its community. Along with the standard vocabulary and grammar lessons, you can submit writing and speaking exercises and get corrections from native speakers around the world. Upgrade to Premium Plus, and you also get AI conversation and pronunciation feedback.

Reviewers note it balances structured lessons with real human input across roughly 14 languages. Pricing is subscription-based, ranging from $6 to $8 per month, depending on the plan and any promotions.

Pros

  • Feedback from native-speaker community

  • Mix of lessons and real practice

  • Free tier available

Cons

  • Free tier is limited

  • Fewer languages than some rivals

Product image of Memrise
Memrise

Memrise's calling card is real native-speaker video, short clips of actual people saying words and phrases in everyday settings, which reviewers say helps pronunciation and comprehension stick.

Across 30-plus languages, it leans on a gamified, vocabulary-heavy approach, and the Pro tier adds AI chatbot practice for conversation. Reviewers commonly knock it for being thin on structured grammar, so it works better for building vocabulary than for mastering the rules.

There's a free tier to start, and Pro runs around $24.99 per month, with a lifetime option for $329.99.

Pros

  • Real native-speaker video clips

  • Strong for vocabulary building

  • Free tier available

Cons

  • Light on grammar instruction

  • Less depth for advanced learners

Product image of Lingoda
Lingoda

Lingoda is a different animal from the rest of this list. Instead of solo lessons, it puts you in live online classes with real teachers over video, either in small groups or one-on-one. It sticks to English, Spanish, French, and German, follows a structured CEFR curriculum, and awards you a certificate upon completing each level.

That live human instruction is the biggest draw and the highest cost, with plans running well above app subscriptions, often around $6-$8 per group class and more for private sessions.

For learners who want accountability and real conversation practice and don't mind paying for it, Lingoda is the one to pick. Read our complete Lingoda review.

Pros

  • Live classes with real teachers

  • Structured CEFR curriculum

  • Certificate at each level

Cons

  • Much pricier than self-guided apps

  • Limited to four main languages

What to consider when buying a language-learning app

Match the method to how you learn

The biggest difference between these apps isn't price. It's teaching philosophy. Gamified apps like Duolingo and Mondly make it easy to build a daily habit but can feel shallow when you want depth. Conversation-first apps like Babbel put practical speaking front and center. Audio programs like Pimsleur suit listeners and hands-free study. Immersion tools like Rosetta Stone teach through association with minimal translation, and live-class services like Lingoda offer real human instruction. Before you subscribe, be honest about which style keeps you coming back.

Know what fluency requires

Every honest reviewer and expert will tell you the same hard truth: No app alone will make you fluent. Most cap out around the upper-intermediate (B2) level, and real fluency takes real-world conversation and immersion. That's no reason to skip apps, because they're excellent for building a foundation and a habit. It's just a reason to set realistic expectations and plan to supplement with speaking practice as you advance.

Free vs. paid

If you're not sure you'll stick with it, start free. Duolingo runs full courses at no cost, and Mondly, Busuu, and Memrise all have free tiers to test the waters. Paid apps unlock more effective tools like conversation practice, offline mode, ad-free study, and deeper grammar. When you know you're in it for the long haul, look for annual or lifetime plans, because they dramatically reduce the effective monthly cost and often go on sale.

Languages offered

Not every app teaches every language. Duolingo (40) and Pimsleur (50-plus) have the broadest catalogs, including less common options. Babbel (14) and Rosetta Stone (25) stick to the most-studied languages but cover them in depth. If you're learning something outside the usual Spanish-French-German lineup, check the language list before you commit.

FAQs

What is the best app to learn a language?

For most people, we recommend Babbel for its structured, conversation-first lessons. If you want to start for free, Duolingo is the best on-ramp. The best app for you depends on your budget, your goals, and how you like to learn.

Can you become fluent with a language app?

Not on an app alone. Most language apps, including Babbel, top out around the B2 (upper-intermediate) level. As Reviewed's language-learning expert, Dr. Esther Gutierrez Eugenio, tells us, apps are excellent for practicing in a controlled, low-pressure environment, but achieving true fluency still requires real-world interaction and immersion.

Are free language apps like Duolingo worth it?

Yes, especially to start. In our testing, Duolingo was an excellent, no-risk way to build a habit and pick up conversational vocabulary, and its methods are backed by research. Just know that its grammar instruction is thin, and some of its best-practice tools require a paid Super subscription.

How much do language-learning apps cost?

It ranges widely. Duolingo and several rivals are free at the basic level. Subscription apps cost about $6-$25 per month, and many offer lifetime plans (Babbel around $299.99; Rosetta Stone often discounted to $149–$199) that pay off for long-term learners. Live-class services like Lingoda cost considerably more.

How much time do I need to spend to see results?

Most of these apps are built around short daily sessions of 5 to 30 minutes, but consistency matters far more than marathon study. In our experience, the apps that kept us coming back every day through streaks, reminders, and quick lessons produced better results than more rigorous programs we used sporadically.

Why you should trust our expertise

Reviewed has spent years using and evaluating language-learning apps in real life, not just skimming feature lists. We used Babbel for more than two years and Duolingo for about a year, and we put Pimsleur, Rosetta Stone, and Mondly through hands-on testing, learning real languages along the way, including German, Spanish, and Arabic. For our Babbel review, we also consulted Dr. Esther Gutierrez Eugenio, a language-learning expert with a PhD in Language Education and more than 20 years of experience teaching and researching languages.

For the apps in this guide we haven't formally reviewed, meaning Busuu, Memrise, and Lingoda, we've drawn on manufacturer information and reputable third-party reviews, and we've labeled them as such rather than implying hands-on testing. We update this guide as apps change, prices shift, and we finish new reviews.
