7 Best AP® Flashcard Apps in 2026 (Including the Free Ones)
Fiveable doesn't make flashcards, so no app on this page is ours. These are the seven apps worth using for the memorization half of AP studying. Quizlet and Knowt prices were checked in September 2026 against their own pricing pages. The rest are as listed on each app's pricing page, so confirm before you pay.
Quizlet is still the best overall flashcard app, Knowt is the best one you can use without paying, and Anki keeps material in your memory longest if you can tolerate its interface. The other four cover narrower needs.
We Build the Other Half
Fiveable's key terms make good deck material for any app on this list. The subscription covers what flashcards can't do: practice with explanations and full-length exams in all 42 AP subjects, with graded FRQs in 37 of them.

1. Quizlet
Best for: most students, if the caps don't bother you.
Quizlet is the app most students land on first, and it earns the spot two ways. Its public set library is the largest of the seven, so your teacher's exact term list is probably already in it, and its mobile app is the smoothest here.
- a public set library no other app here comes close to
- the best-built iOS and Android flashcard experience here
- Quizlet Live for class review
Where it stops: the free plan limits how much Learn and Test you get and shows ads, while Knowt gives you those modes without caps. Full breakdowns: Knowt vs Quizlet and best Quizlet alternatives.
Price: Quizlet Plus is listed at $2.99/month billed $35.99/year, with a Plus Unlimited tier at $44.99/year; the 7-day free trial applies to annual plans only (quizlet.com/upgrade, September 2026).
2. Knowt
Best for: studying without paying.
Knowt's free Basic plan includes the study modes Quizlet keeps behind Plus, with no daily caps, and its importer pulls your existing Quizlet sets over at no cost.
- Learn-style and test modes with no daily caps
- one-click Quizlet set and folder import
- deck generation from your own notes, video, or PDFs
Where it stops: its public library is smaller than Quizlet's and the mobile app is less polished. It's a flashcard app first, and the AP hub it added later is a smaller part of the app than the decks that made its name. Full comparison: Fiveable vs Knowt.
Price: Basic is free; Ultra is listed at $12.49/month billed $149.99/year, or $24.99 month to month (knowt.com/plans, September 2026).
3. Anki
Best for: remembering material months later.
Anki schedules every card by how well you recalled it, so the facts you keep missing come back sooner. Over a full year, it keeps a large body of material fresh with less review time than drilling on a fixed schedule.
- free on Windows, macOS, Linux, Android, and the web
- the most detailed spaced-repetition scheduling of any app here
- a large shared-deck library and add-ons for almost anything
Where it stops: the interface looks like software from 2009 and the defaults need tuning. It rewards tinkering and frustrates anyone who wants to start studying in the next ten minutes.
Price: free everywhere except iPhone and iPad, where it's listed as a one-time $24.99.
4. Brainscape
Best for: spaced repetition without the setup.
After each card you rate how well you knew it from 1 to 5, and Brainscape schedules reviews from that rating. It's the Anki idea with far less configuration.
- rate-as-you-go scheduling that needs no setup
- clean apps on web, iOS, and Android
- certified decks for standardized tests
Where it stops: the free tier gives you less than Knowt's, and Pro costs more per year than Quizlet Plus. It's a narrow pick, and a good one for what it does.
Price: free tier; Pro listed at $95.99/year.
5. Cram
Best for: making a deck in the next two minutes.
Cram keeps it simple: make a set, study it, close the tab. There's no scheduling algorithm to think about.
- deck creation with no subscription
- a large public set library to search
- simple card and memorize modes
Where it stops: it's basic, the ads are noticeable, and public set quality is uneven, so check a set before you trust it.
Price: free, ad supported.
6. Memrise
Best for: AP language vocabulary.
If your decks are Spanish, French, or Mandarin vocabulary, Memrise does more than a general flashcard app: it pairs repetition with clips of native speakers saying the words.
- native-speaker video for pronunciation
- courses built around real conversational phrases
- review reminders that keep the streak alive
Where it stops: it's built for languages. Using it for AP Bio terms or APUSH dates means fighting an app built for something else.
Price: free tier, with paid plans for full courses.
7. Kahoot, Blooket, and Wayground
Best for: reviewing with your whole class.
These are the games your teacher runs on the projector. Kahoot, Blooket, and Wayground (formerly Quizizz) make group review fun, and students join at no cost.
- fast, competitive review a class enjoys
- teacher-built sets tied to what you covered this week
- works on whatever phone or laptop is already in the room
Where it stops: they're built for the classroom. Studying alone at 10pm, you want one of the apps above instead.
Price: free to join, with paid teacher plans.
A Word About Paper
Index cards still work, and writing the cards by hand is itself a review pass. A two-column Google Doc with the answers covered does the same thing. If an app feels like one more thing to manage, paper is the simplest option there is.
Where Fiveable Fits
Fiveable doesn't make flashcards. What we do have is key terms for every AP course: term-by-term lists that make good source material for building decks in any app above.
Any of these apps will handle memorization. What flashcards can't do is turn terms into exam points, because the exam hands you documents, data, and prompts and grades what you do with them. That takes practice with explanations, FRQs that get graded, and full-length exams, which is what Fiveable is built for.

Frequently Asked Questions About AP Flashcard Apps
What is the best flashcard app for AP classes?
Quizlet is still the best overall, with the biggest public set library and the smoothest app, though its free plan limits how much Learn and Test you get. Knowt is the best app you can use without paying: the same study modes come uncapped, and its importer moves your existing Quizlet sets over. Anki keeps material in your memory longest, if you can tolerate its setup. We checked those prices and plan limits in September 2026.
Does Fiveable have flashcards?
No. Fiveable's key terms pages are term-by-term lists for each AP course, which make good source material for building decks in any app on this list. The subscription covers the other half of studying: practice with explanations, graded FRQ practice, and full-length exams.
Are flashcards enough to pass an AP exam?
For most subjects, no. Flashcards handle recall, while AP exams mostly grade what you do with the material: analyzing documents and data, writing free response that earns specific points, pacing a timed test. Memorize with a flashcard app, then put your remaining time into exam-format practice and graded free response.
Which free flashcard app should I pick?
Most students should start with Knowt, where the study modes Quizlet keeps behind Plus are free and uncapped, and where an importer brings your existing sets across. Anki is also free everywhere except iOS, and it is stronger for months-long memorization, though it takes longer to set up. We checked both in September 2026.
