Quick Take: Which Language Learning App Should You Pick?
If you want the short answer: Duolingo for casual daily practice, Pimsleur for speaking skills, and Italki if you want real conversations with tutors. Everything else depends on your goals, budget, and how serious you are about actually learning.
I spent the last 6 months rotating between these apps while learning Portuguese. Some I stuck with, some I deleted after a week. Here’s what actually worked.
9 Best Language Learning Apps Compared
| App | Best For | Price | Languages | Offline Mode |

1. Duolingo – Best Free Option for Building a Daily Habit
Look, you probably already have Duolingo on your phone. Over 100 million people do. The gamification is borderline addictive – streaks, XP, leaderboards, that passive-aggressive owl reminding you to practice.
The free tier is genuinely usable. You get full access to all courses with ads between lessons. Super Duolingo ($7.99/month) removes ads, adds unlimited hearts, and lets you download lessons for offline use.
What Duolingo Does Well
The bite-sized lessons (5-10 minutes each) fit into any schedule. The AI-powered features added in late 2025 include Duo Max, which gives you conversational practice with an AI character. It’s surprisingly good for beginners.
The CEFR-aligned courses now go up to B2 level for major languages like Spanish, French, and German. That’s intermediate-upper, enough to hold real conversations.
Where It Falls Short
Duolingo is weak on grammar explanations. You learn patterns through repetition, which works for some people and frustrates others. The sentence translation exercises can feel repetitive after a while. And the speaking exercises use speech recognition that’s… generous. It accepted my butchered Portuguese pronunciation more often than it should have.
For languages with smaller user bases (Finnish, Navajo, Hawaiian), the courses are noticeably thinner.
Pricing
- Free: Full courses with ads, limited hearts
- Super Duolingo: $7.99/month (annual) or $13.99/month (monthly)
- Duo Max: $13.99/month (annual) – adds AI conversation partner
- Family Plan: $9.99/month for up to 6 people
2. Babbel – Best for Practical, Conversation-Ready Skills
Babbel takes a different approach than Duolingo. Instead of gamification, it focuses on getting you to actual conversations faster. Lessons are built around real-world scenarios: ordering food, asking for directions, small talk at work.
I noticed a difference in about 4 weeks. With Duolingo, I could translate sentences. With Babbel, I could actually say things a real person might say in a real situation. The speech recognition is stricter too, which I appreciated.
Course Structure
Each lesson runs 10-15 minutes and follows a clear progression. Babbel’s courses are designed by linguists (they have a team of 150+), and it shows. Grammar is explained in context rather than isolated drills.
The review system uses spaced repetition to bring back words you’re about to forget. Not revolutionary, but it works.
The Downside
Only 14 languages. If you want to learn Japanese, Korean, Mandarin, or anything outside the European/mainstream set, Babbel can’t help you. The content is also somewhat rigid – you follow their path with limited ability to skip ahead or customize.
No free tier beyond a trial lesson. At $14.95/month (or less with annual billing), it’s mid-range pricing.
3. Pimsleur – Best for Speaking and Pronunciation
Pimsleur is the app your polyglot friend swears by. The method is audio-first: you listen, repeat, and respond to prompts. No flashcards, no matching exercises, just pure audio drills based on a method developed in the 1960s by linguist Paul Pimsleur.
Honestly? It feels old-school. And it works.
After 30 days of Pimsleur Portuguese, my pronunciation was noticeably better than after 3 months of Duolingo. The spaced recall technique forces you to actively produce language rather than passively recognize it.
How It Works
Each lesson is exactly 30 minutes of audio. You hear a conversation, break it down phrase by phrase, and practice responding. The app adds reading lessons and quick-match vocabulary games, but the audio core is what makes Pimsleur unique.
51 languages available, including less common ones like Dari, Ojibwe, and Tagalog.
What I Didn’t Love
It’s slow. By design. Pimsleur introduces maybe 20-30 new words per unit, and each unit is 30 lessons. If you want to build vocabulary fast, this will frustrate you. The reading and writing components feel like afterthoughts bolted onto the audio method.
At $14.95/month for one language or $20.95 for all languages, it’s not cheap for what you get.
4. Busuu – Best Blend of App Learning and Human Feedback
Busuu sits in an interesting middle ground. It has structured courses like Babbel, gamification elements like Duolingo, and a community feature where native speakers correct your writing exercises.
That community correction feature is the real differentiator. You write a short text, submit it, and actual native speakers give feedback. Sometimes within minutes. I got corrections on my Portuguese writing from people in Brazil and Portugal, with explanations of why my phrasing sounded weird.
Course Quality
Courses are developed with McGraw-Hill Education and go up to B2 level. The AI-powered pronunciation feedback improved a lot in the 2025 update – it now catches specific phoneme errors rather than just giving a generic score.
14 languages, similar to Babbel’s range. The free tier lets you access beginner courses but locks most features behind Premium ($13.99/month).
Drawbacks
The community corrections are hit-or-miss. Sometimes you get detailed feedback from a language teacher. Sometimes you get “looks good 👍” from someone scrolling during their commute. The app can also feel cluttered – there’s a lot going on between lessons, reviews, community, and study plans.
5. Italki – Best for Live Tutor Sessions
Italki isn’t really an app in the same category as the others. It’s a marketplace connecting you with language tutors and community tutors for one-on-one video lessons. No gamification, no AI drills – just you and another human talking.
Here’s the thing: nothing replaces actual conversation practice. I made more progress in 8 Italki sessions than in weeks of app-based study. A real person catches errors that no app would flag, adjusts to your level in real time, and can explain cultural context.
How Pricing Works
Professional teachers charge $15-40/hour depending on the language and their experience. Community tutors (native speakers without formal teaching credentials) charge $5-15/hour. For less commonly taught languages, you can find tutors for $5-8/hour.
You book individual sessions, no subscription required. Trial lessons are available at a discount.
The Trade-Off
It requires scheduling and commitment. You can’t do a quick 5-minute lesson while waiting for coffee. The quality depends entirely on finding a good tutor, and that might take a few tries. There’s no structured curriculum unless your tutor provides one.
Best used alongside another app for vocabulary and grammar, with Italki sessions for speaking practice.
6. Rosetta Stone – The Veteran That Adapted
Rosetta Stone has been around since 1992. The old CD-ROM software your school computer lab probably had. They’ve reinvented themselves as a subscription app, and honestly, the modern version is better than its reputation suggests.
The immersive method (no translations, only target language from day one) is polarizing. Some learners thrive with it. Others find it maddening. I found it effective for building intuition about sentence structure, less effective for vocabulary.
2026 Updates
The AI conversation partner they added works well. TruAccent speech recognition is still one of the most accurate in the business – it’ll reject your pronunciation more aggressively than any other app. Good if you want to sound correct. Frustrating if you’re a perfectionist.
25 languages, lifetime purchase option available (around $179 for all languages). That’s a selling point if you plan to use it long-term.
Why I Stopped Using It
Progress felt slow for the time invested. A 30-minute Rosetta Stone session covered less ground than 30 minutes on Babbel. The immersive-only approach means you sometimes spend 5 minutes figuring out what a picture is supposed to represent instead of actually learning the word.
7. Memrise – Best for Vocabulary Through Real-World Content
Memrise rebuilt their entire app in 2025, and the new version centers around video clips of native speakers. Not actors in a studio, but regular people filmed on streets and in homes across different countries. You hear the language as it’s actually spoken, with all the speed, slang, and mumbling that entails.
The vocabulary system uses spaced repetition with mnemonics (called “mems”) created by the community. Some are brilliant memory aids, some are bizarre, but the variety helps things stick.
Free vs Paid
The free version gives you limited daily reviews and access to basic courses. Pro ($8.49/month) unlocks everything: all video content, offline mode, grammar bots, and the AI conversation practice feature.
23 languages, with stronger courses for major languages and thinner content for less popular ones.
Weaknesses
Grammar instruction is minimal. Memrise is primarily a vocabulary tool, and while it does that well, you’ll need something else for sentence construction and grammar rules. The community-created courses vary wildly in quality.
8. HelloTalk – Best Free Language Exchange
HelloTalk matches you with native speakers of your target language who want to learn your language. You text, voice call, or video chat with them. Built-in translation, correction tools, and a social feed where you can post in your target language and get feedback.
Not gonna lie, this is the most underrated tool on the list. I connected with a guy in Lisbon who corrected my Portuguese texts every day for a month. In exchange, I helped with his English. Cost me nothing.
Features That Help
The in-app translation and correction tools are thoughtful. You can tap any message to translate it, and the correction feature lets your partner mark errors in a clean way. Voice-to-text transcription helps when you can’t understand a voice message.
150+ languages. The free version limits you to one target language; VIP ($6.99/month) removes that limit and adds extra features.
Caveats
It depends on finding good language partners, and some people treat it as a dating app. The matching algorithm improved, but you might still get a few awkward interactions before finding serious study partners. It’s also social media-esque, which means potential for time-wasting scrolling.
9. LingQ – Best for Intermediate Learners Who Love Reading
LingQ was created by Steve Kaufmann, a polyglot who speaks 20+ languages. The concept: import any content (articles, books, podcasts, YouTube transcripts) and the app helps you read it with built-in dictionary lookups and progress tracking.
For intermediate learners who’ve outgrown beginner courses, LingQ fills a gap that most apps ignore. Instead of manufactured textbook content, you’re reading real things you actually want to read.
How It Works
Words you don’t know are highlighted in blue. Click to see definitions, hear pronunciation, and save to your vocabulary list. As you encounter words repeatedly across different contexts, your “known words” count grows. It’s motivating to see that number increase.
42 languages. The library includes thousands of lessons, and you can import literally anything with text.
Not for Everyone
The interface is dated and takes getting used to. LingQ is not intuitive on first use. It also assumes you have some foundation – absolute beginners will struggle with the content-first approach. At $12.99/month, it’s a niche tool for a specific type of learner.
How I’d Combine These Apps
After testing all of these, here’s the combination I settled on:
Daily routine (20 min): Duolingo for streak maintenance + vocabulary review. Five minutes on the train, done.
Active study (30 min, 4x/week): Pimsleur audio lessons during walks. The speaking practice is unmatched.
Weekly conversation (1 hour): Italki session with a tutor. This is where everything comes together.
Passive input: LingQ for reading Portuguese news articles. Memrise videos when I want a break from structured study.
Total cost: about $35/month. Roughly what one in-person group class would cost.
Picking the Right App for Your Level
| Your Level | Primary App | Add-On |
|---|---|---|
| Complete beginner | Duolingo or Babbel | Pimsleur for pronunciation |
| Elementary (A2) | Babbel or Busuu | HelloTalk for practice |
| Intermediate (B1) | LingQ or Memrise | Italki for conversation |
| Upper-intermediate (B2+) | LingQ + native content | Italki for fluency |
FAQ
Can you actually become fluent from an app?
Apps alone won’t make you fluent. They’re a tool, not a complete solution. The research is clear: you need output practice (speaking and writing with real people) to develop fluency. Apps are great for building vocabulary, learning grammar patterns, and maintaining daily practice. But at some point, you need Italki, HelloTalk, or real-world immersion.
Is Duolingo enough by itself?
For reaching A2-B1 level in major languages, Duolingo can get you surprisingly far if you use it consistently for 6-12 months. But the speaking practice is weak, and the content gets repetitive at higher levels. I’d pair it with at least one speaking-focused resource.
Which app has the best speech recognition?
Rosetta Stone’s TruAccent is the strictest and most accurate. Pimsleur’s is decent. Duolingo’s is the most lenient, which can be a problem if you want honest feedback on pronunciation.
Are free language learning apps worth it?
Duolingo’s free tier is legitimately useful. HelloTalk’s free version works well for finding language partners. Memrise and Busuu have limited free tiers. For everything else, you’re looking at $8-20/month, which is still dramatically cheaper than traditional classes ($30-60/hour).
How long does it take to learn a new language with an app?
The FSI (Foreign Service Institute) estimates 600-750 hours for “easy” languages (Spanish, French) and 2,200 hours for “hard” ones (Mandarin, Arabic) to reach professional working proficiency. Daily app use of 30 minutes equals about 180 hours per year. So realistically, 3-4 years for an easy language to reach advanced level with apps alone. Combining apps with tutoring and immersion can cut that significantly.
Duolingo or Babbel – which should I pick?
Duolingo if you want free, gamified practice and need motivation to study daily. Babbel if you’re willing to pay and want to reach conversational ability faster with better-structured content. I’d say Babbel produces better results per hour invested, but Duolingo is hard to beat on accessibility.
