Best Free Flashcard Apps 2026: 6 Options Compared

Flashcard apps differ most in how they schedule reviews, so choose by that before you look at features. Anki uses spaced repetition with open-source code, and its desktop app, AnkiWeb sync and AnkiDroid are free, although the iOS app is a paid official version; check the App Store for the current price. Quizlet is the best known for ready-made decks, but the page that lists its free limits returned an error, so confirm what is free. Brainscape's free plan includes unlimited cards, import, 2,500 pre-loaded cards, spaced repetition and AI card generation. Knowt focuses on turning notes into cards, and RemNote mixes notes with flashcards, giving unlimited notes and cards on its free plan, with 250 AI credits a month. Memrise is aimed at languages, with vocabulary courses and a paid plan for extra features. The trade-off is setup effort against polish. Anki asks you to learn card types and settings, and repays that with the most control over how you review. The others get you started in minutes but may place features such as AI generation or offline study behind a subscription. Test a deck of twenty cards in your top two choices, and keep your cards exportable so you can leave if the pricing changes.
