The Best Flashcard Apps for Android in 2026

TL;DR. On Android, AnkiDroid is the best flashcard app for most serious learners: it is free, open source, works offline and supports the FSRS scheduler. Quizlet wins on its shared library, Knowt on free features and Quizlet import, Brainscape on its simple confidence-based review, and RemNote if you want notes and cards in one place. If you want an AI to write the cards from your notes, the SimpleQuizMaker flashcard maker runs in your phone's browser (there is no Android app yet). Prices checked as of September 2026. (Using an iPhone? See our iPhone flashcard app guide.)

Why Android is a slightly different question

On iPhone, the best-known power tool (AnkiMobile) costs $24.99. On Android, the equivalent, AnkiDroid, is free, with no ads and no in-app purchases gating features. That changes the maths: the most capable app is also the cheapest one. The question for Android users is less "what can I afford" and more "how much setup am I willing to do".

Comparison table

1. AnkiDroid: best overall for serious study

What is good. Full Anki on your phone: FSRS scheduling (supported since AnkiDroid 2.17), cloze deletions, custom card templates, sync with Anki desktop through AnkiWeb, and full offline study. Shared decks such as AnKing for medicine or frequency-list decks for languages import straight in.

What is not. You make cards by hand or import someone else's. The first-run experience assumes you know what "new cards per day" and "desired retention" mean. Start with 10 to 20 new cards a day, not the default you might be tempted to raise.

2. Quizlet: best shared library

What is good. Whatever you are studying, someone has probably already made a set. The Android app is polished, Match is fun, and many schools run on it.

What is not. Learn and Test are capped on the free plan, and offline study needs Plus. Our Is Quizlet Plus worth it? post works through whether the upgrade pays off.

3. Knowt: best free Quizlet-style app

What is good. Unlimited flashcards on the free Basic plan, a big public library, AI tools that turn notes into cards, and a one-click import of public Quizlet sets. It is the closest thing to what Quizlet's free plan used to be.

What is not. The most powerful AI features (PDF, video and lecture summarizers, the voice tutor) are on Ultra, which is expensive month to month.

4. Brainscape: best for a no-fuss routine

What is good. Brainscape's confidence-based repetition is easy to understand: you rate each card 1 to 5 by how well you knew it, and low-confidence cards come back sooner. The free plan lets you type unlimited cards and use AI to make some; Pro ($7.99 a month billed yearly as of September 2026) unlocks unlimited AI, full access to certified expert decks, and multimedia.

What is not. Much of the premade library needs Pro, and there is less control than Anki.

5. RemNote: best if you take notes on your phone too

What is good. Write notes and turn lines into flashcards inline, with spaced repetition built in. Good for students who want one app for both.

What is not. It is a note-taking system first, which means a learning curve, and AI features sit on higher tiers. Compare it in our RemNote alternative page.

6. SimpleQuizMaker in the browser: fastest deck from notes

There is no SimpleQuizMaker Android app on Google Play yet, but the website works in Chrome on Android, so it belongs on this list for one job: turning a topic or a block of notes into a deck quickly.

How it works. Type a topic ("French irregular verbs, present tense") or paste up to 50,000 characters of notes. For a PDF, copy the text from your PDF and paste it in. Pick a card count: up to 20 on the free plan, up to 50 on Student. You get an editable deck, reviewed with an SM-2-based scheduler: rate each card and its next interval stretches or shrinks.

Honest limits. No offline mode, no export to Anki or CSV, no image-occlusion cards, and 5 AI generations a month on the free plan (25 on Student, shared with quiz generation). If you need offline study on a train, use AnkiDroid.

How to choose in 30 seconds

A simple Android study routine

Fifteen new cards a day for a 15-week semester is about 1,500 cards, which is a full course's worth for most subjects. For the reasoning, see the spaced repetition guide and our best study apps for students.
