If you're learning a language, flashcards with spaced repetition are still the most efficient way to move vocabulary into long-term memory. The good news: you don't need to pay for it. Several genuinely free flashcard apps work well for language learners in 2026.
This guide compares the best free options honestly — what each one is actually good at, where it falls short, and which fits your situation. No app here requires a paid plan to get real value.

The honest breakdown
Voccle — best if making cards is your bottleneck
Most people quit flashcards not because reviewing is hard, but because making cards is tedious. Voccle removes that step: paste an article, a news story, or a YouTube video, and its AI extracts the vocabulary worth learning and builds complete cards — definition, example sentence, and pronunciation — in seconds. It uses FSRS (the modern spaced-repetition algorithm), runs in the browser and on mobile, supports 8 languages, and is free with no account required to start.
Trade-off: it's a newer app, so there's no large library of community-shared decks yet. If you learn from your own reading material, that doesn't matter; if you specifically want pre-made decks, Anki or Quizlet have more.
Anki — best for total control
The long-standing gold standard. Powerful, endlessly customizable, and free on desktop and Android (the iOS app costs money). The catch is a steep learning curve and manual card creation. Great if you enjoy tuning your own system.
Quizlet — best for students and shared sets
The most widely used flashcard platform, with hundreds of millions of pre-made study sets. The free tier has ads and gates some study modes, but it's genuinely usable for free and beginner-friendly.
Knowt — best free Quizlet alternative
A free app that mirrors much of Quizlet's study experience and can import Quizlet sets, popular with students who don't want to hit Quizlet's paywall.
Memrise — best for guided beginner courses
Strong for beginners who prefer structured, curated courses over building their own cards. The free tier is limited but a reasonable starting point.
WaniKani — best for Japanese kanji
Not a general flashcard app — a focused SRS system for learning Japanese kanji and vocabulary. The first levels are free.

Frequently asked questions
What is the best free flashcard app for language learning? There isn't one winner for everyone. If your main problem is the time it takes to create cards, Voccle is the best free option because it generates flashcards from any text or video automatically. If you want the most powerful and customizable system and don't mind manual setup, Anki is the best free choice on desktop and Android.
Is there a free flashcard app that makes cards for you? Yes. Voccle is free and uses AI to build flashcards — with definitions, example sentences, and pronunciation — from any text or YouTube video you paste in, so you don't have to write cards by hand.
Is Anki really free? Anki is free on desktop and on Android. The official iOS app (AnkiMobile) is paid, which funds development of the others.
