Best free flashcard apps, no paywall, 2026

Most "free" flashcard apps lure you in, then lock spaced repetition or your own decks behind a subscription right before exam season. QuickDeck Study takes the opposite approach: it runs the open-source FSRS-6 algorithm entirely on your device, imports the Anki .apkg and Quizlet CSV decks you already own without an account, and has never shipped a paywall. Mothertongue tackles a different gap, helping diaspora families keep a heritage language alive with hand-curated Yoruba, Tagalog, and Marathi decks, on-device pronunciation audio, and a calm pace built around learning rather than streaks. Both are free, work offline, and keep your study data on your phone.

FAQ

Are these flashcard apps actually free, with no subscription? ▾

Yes. QuickDeck Study has never had a paywall in its source code, and Mothertongue ships its language decks at no cost. Neither app gates spaced repetition or core features behind a subscription.

Do they work offline? ▾

Yes. QuickDeck runs the FSRS-6 spaced repetition algorithm in pure Swift on-device, and Mothertongue's pronunciation audio uses on-device speech synthesis. Both work without an internet connection, and your study data stays on your phone.

Can I bring in flashcard decks I already made in Anki or Quizlet? ▾

QuickDeck Study can. It imports Anki .apkg files and Quizlet CSV exports locally, with no account required, so you can reuse decks you already built. Mothertongue is focused on its own curated 600-word heritage-language decks rather than custom imports.
