The Best Free Apps to Learn Spanish (and What Each One Is Actually For)

Every Spanish app claims to teach you Spanish. Most of them teach you one part of Spanish quite well and leave you to discover the rest on your own — usually the part where a real person speaks to you at normal speed.

Here is what each kind is actually for.

🦉 Vocabulary and habit

Duolingo — free with ads, full course, and unbeatable at one thing: getting you to show up daily. The gamification is the product. Weak on listening to real speech, because the audio is synthesised or recorded slowly, and weak on producing your own sentences.

Use it as a habit anchor and a vocabulary drill. Do not mistake finishing the tree for learning Spanish.

🃏 Retention

Anki — genuinely free forever on desktop and Android (the iOS app is paid). Spaced repetition flashcards: it shows you a card just before you would have forgotten it.

Ugly, unfriendly, and the most effective retention tool there is. One rule: build your own deck from words you met in videos rather than downloading someone's 5,000-card deck. The deck you make is worth far more than the deck you get.

🎧 Listening to real speech

This is the gap in almost every app, because scripted audio is easy to produce and real speech is not.

Gappier — works on any YouTube video: it takes the video's real subtitles, hides some of the words, and pauses until you type what you heard. Free plan with a daily limit. The point is that the material is real native speech rather than studio recordings, and that you have to produce the word rather than recognise it.

Language Reactor / Trancy — browser extensions adding dual subtitles and clickable words on YouTube. Free tiers are usable. The opposite approach: they add support for reading, rather than removing it to force listening. Worth knowing both exist and deciding which problem you have.

🗣️ Speaking

Tandem / HelloTalk — free language exchange. You are matched with Spanish speakers learning English and trade time instead of money. The free tier is genuinely usable; the friction is scheduling and finding someone you click with.

Nothing else on this page will make you speak. This category is not optional if speaking is your goal.

📊 What to actually install

Most people need two apps, not six:

  • One for habit and vocabulary — Duolingo or Anki, depending on whether you need fun or efficiency.
  • One for real listening — something that puts you in front of native speech.

Plus one exchange app when you are ready to speak.

⚠️ What no app does

  • Prepare you for a real conversation. App audio is clear, slow and waits for you. People are none of those.
  • Correct your grammar meaningfully. Automated correction catches the obvious and misses the things that make you sound foreign.
  • Replace hours of input. Ten minutes a day on an app is ten minutes. The 600-hour figure in how to learn Spanish fast does not care how gamified those hours were.

❓ Frequently asked questions

What is the best free app to learn Spanish from scratch?

Duolingo for the first few months, because structure and habit matter most at the start. Add video early — see learn Spanish from scratch.

Is Duolingo enough to learn Spanish?

No. It builds vocabulary and habit, not comprehension of real speech. People who finish it and then watch a Spanish film usually get a shock.

Are the free versions good enough?

For everything except conversation with a teacher, yes. See learn Spanish free online.

What about apps that work offline?

Duolingo and Anki both work offline. Anything based on real video needs a connection, since the video is the material.

Which app is best for listening?

Any that uses real native content rather than recorded lessons. That is the whole distinction that matters in this category.

✅ In short

  • Duolingo for habit, Anki for retention, an exchange app for speaking.
  • The missing piece in most apps is real native speech.
  • Two apps used daily beat six installed.
  • No app replaces hours of listening to actual Spanish.
