App comparisonWhich flashcard app fits how you study?

There is no single best flashcard app. Here is what each tool says about itself, side by side, and who each one suits.

Pick by how you study

There is no single best flashcard app. The right one depends on whether you want a huge ecosystem, a notes workspace, a simple shared-set quizzer, or a calm scheduler tuned to you. This page compares what each tool says about itself, then gives a plain recommendation by use case.

Anki

Free desktop apps on Windows, macOS and Linux, a free Android app and an iOS app, free sync through AnkiWeb, and an add-on system. The homepage says decks of more than 100,000 cards are handled without problems. It is the most flexible option in this list. Its manual describes FSRS as an opt-in alternative to the legacy scheduler.

Quizlet

Quizlet is built around study sets and several study modes. Its help center describes a spaced repetition feature in which you rate your recall after each card and Quizlet uses the ratings to decide when the card returns, which the feature page says switches on automatically for sets of 100 or more terms. The same help center says Learn mode is for subscribers, with a limited number of free rounds per set. Quizlet's own pricing page blocked our automated fetch, so we do not quote prices; see its upgrade page directly. Quizlet suits shared study sets and quick sessions.

RemNote

Notes and flashcards in one place. Free plan: unlimited notes and flashcards, three annotated PDFs or files, five image occlusion cards and 250 AI credits a month, per its pricing page. Paid plans add PDF annotation and AI features. It suits people who take notes and want cards to come from them.

Mochi

A clean, local-first app with Markdown cards, a free plan and Pro at $5 per month for sync and extras. It suits people who like writing cards in Markdown.

Cirello

Cirello is a web app with FSRS-6 scheduling with parameters refit to your history, bulk paste of front::back lists with duplicate detection, images on either side of a card, and cards that prompt from a book, website or image resource. Reviews can run in reverse, listening, quiz or mixed modes, decks export to a list or CSV, and exam plans pull reviews in before a date you set. It counts progress by the week. It is free during the beta, with a subscription planned later. It is early: web only, no cloze cards, no add-ons. See the flashcard app overview and what it can and can't do today.

Which should you choose?

  • You want maximum flexibility and apps on every device now: Anki or Mochi.
  • You want notes, PDFs and cards in one workspace: RemNote.
  • You want shared sets and quick modes: Quizlet.
  • You want a calm web app with FSRS-6 by default and source-linked cards: Cirello.

Whatever you choose, good cards matter more than the app. Read how to write good flashcards and how many flashcards to review per day, and for the scheduling side see the comparison of spaced repetition apps.
