Language learning apps have come a long way from flashcard drills. The best ones now use AI-driven spaced repetition, real conversation practice, and adaptive difficulty that adjusts to how you’re actually learning. Here are seven that genuinely work — no gimmicks, just apps that have helped real people build real language skills.
Short Answer: For most people starting out, Duolingo builds the habit and Anki builds the vocabulary. For speaking practice, iTalki or Pimsleur are more effective than apps alone. If you want one paid app that takes you furthest, Rosetta Stone or Babbel are the most structured options.
1. Duolingo — Best for Building a Daily Habit
Duolingo is the most downloaded language app in the world, and the reason isn’t that it teaches languages fastest — it’s that it makes you come back every day. The streak mechanic, short lessons, and game-like rewards make it the easiest app to stay consistent with.
It covers over 40 languages and is completely free (with ads). The paid Duolingo Plus removes ads, adds offline access, and adds a few extra features, but the free version is what most people use. Duolingo works best as a complement to other learning rather than as your only tool — it’s strong on vocabulary and grammar patterns, but weak on speaking and listening to natural speech.
- Best for: Beginners, building a daily habit, vocabulary
- Free version: Yes — fully functional
- Languages: 40+
2. Anki — Best for Vocabulary with Spaced Repetition
Anki isn’t a language app specifically — it’s a flashcard tool built on spaced repetition, which is one of the most research-backed methods for memorising vocabulary. You review cards at optimised intervals so you see words just before you’re about to forget them.
The app is free on desktop and Android. The iPhone app costs a one-time £25 (this funds development for all platforms). You can download pre-made decks for almost any language from the Anki shared deck library, or create your own. Once you understand how it works, Anki is one of the most powerful learning tools available — many polyglots credit it as their core vocabulary tool.
- Best for: Vocabulary memorisation at any level
- Free version: Yes (desktop and Android); iPhone app is a one-time paid purchase
- Languages: Any — community decks for all major languages
3. Babbel — Best Structured Paid App
Babbel is built by linguists and focuses on practical conversation skills — the kind of language you’d actually use booking a table, asking for directions, or having a real conversation. Lessons are 10–15 minutes, well-structured, and progress logically from beginner to intermediate.
Unlike Duolingo, Babbel doesn’t gamify learning into mini-games. It’s more serious and feels more like a proper course. Subscriptions start at around £7/month on longer plans. It covers 14 languages and includes speech recognition for pronunciation practice.
- Best for: Adults who want structured, practical conversation skills
- Free version: First lesson free; subscription required after
- Languages: 14
4. Pimsleur — Best for Speaking and Listening
Pimsleur is different from every other app on this list — it’s audio-first. You listen and speak, with no reading or writing at all. The method is based on spaced repetition of spoken phrases, and it’s highly effective for building speaking confidence and a natural accent.
Each lesson is 30 minutes of audio — designed to do while commuting, walking, or exercising. It’s more expensive than other apps (around £15–20/month), but for people who want to genuinely speak a language rather than just read it, it’s uniquely effective. Available for 50+ languages.
- Best for: Listening comprehension and speaking ability
- Free version: 7-day trial
- Languages: 50+
Quick tip — best combination:
Duolingo (daily habit) + Anki (vocabulary) + Pimsleur or iTalki (speaking) = the most effective self-study setup
5. iTalki — Best for Real Conversation Practice
iTalki connects you with human language tutors for one-on-one video lessons. You can book professional teachers for structured lessons or “community tutors” (native speakers) for casual conversation practice at lower prices. The difference in progress from actually speaking to a human — versus practising with an app — is significant.
Prices vary widely depending on the tutor, from around £5 to £40+ per hour. Many people combine iTalki with Duolingo and Anki — building vocabulary independently and then using iTalki sessions to actually practise using it in conversation.
- Best for: Speaking practice, conversation confidence
- Free version: No — pay-per-lesson
- Languages: 150+
6. Rosetta Stone — Best Immersive Learning
Rosetta Stone uses an immersion method — you learn by associating images and words without translation, similar to how children learn their first language. It covers reading, writing, listening, and speaking, and the speech recognition (TruAccent) is among the most accurate available in a language app.
It’s one of the pricier options (around £12/month or £180 for a lifetime licence for all languages), but it’s been around since 1992 and has a proven track record. Best suited for people who want a rigorous, structured programme they can follow from beginner level upward.
- Best for: Structured immersive learning, pronunciation
- Free version: 3-day free trial
- Languages: 25
7. Drops — Best for Visual Vocabulary Building
Drops focuses exclusively on vocabulary, using a visual, game-like approach with five-minute daily sessions. It’s not a complete language learning tool — it won’t teach you grammar — but for quickly building up word recognition in a new language, it’s unusually effective and enjoyable. Free with a 5-minute daily limit; the paid plan removes this cap.
- Best for: Visual learners, rapid vocabulary acquisition
- Free version: Yes — 5 minutes/day
- Languages: 50+

Frequently Asked Questions
Can you actually become fluent using only apps?
Apps alone rarely produce fluency. They’re excellent for building vocabulary, grammar patterns, and the habit of daily practice — but speaking fluency requires actual conversation practice with real people. Use apps to build a foundation, then add conversation practice via iTalki or a language exchange partner.
How long does it take to learn a language with apps?
It depends heavily on the language and your consistency. The US Foreign Service Institute estimates 600–750 hours to reach conversational proficiency in French or Spanish, and 2,200+ hours for Japanese or Mandarin. Daily app use helps — but only as part of a broader study approach that includes reading, listening, and speaking.
Is Duolingo actually good?
Duolingo is genuinely good at what it does: making you study every day. Its vocabulary and grammar coverage is solid for most European languages. Where it falls short is speaking practice and advanced grammar. Use it consistently alongside other resources and you’ll make real progress.
Which language learning app is best for children?
Duolingo and Drops are both child-friendly, with visual interfaces and game mechanics that engage younger learners. Duolingo has a specific “Schools” version for classroom use. For children, consistency and fun matter more than method — whatever they’ll actually use is the right choice.
The most important thing with any of these apps is consistency. Fifteen minutes every day beats two hours once a week. Pick one app, commit to a daily streak, and add conversation practice as soon as possible.
