Quizlet's Android app has been polished over years of iteration and it shows. The card creation flow is fast, the search for pre-made decks is powerful, and the interface feels appropriate for a phone. For students who discovered Quizlet through a teacher or classmate sharing a deck, it is the path of least resistance into flashcard-based studying.
The catch on Android - as on every platform - is that Quizlet has been progressively moving its most effective study features behind a paywall. The Spaced Repetition mode, which is the feature that actually makes flashcards more than a passive flip-through exercise, requires Quizlet Plus. The free tier gives you Flashcards, Match, and a couple of test-style modes. These are fine for quick reviews before a quiz, but they do not help you build lasting knowledge over time.
Android users have a distinct advantage here that iOS users lack: AnkiDroid is completely free and offers a better retention algorithm than anything Quizlet offers at any price. For Android users specifically, the Quizlet paywall argument is less of a minor annoyance and more of a fundamental reason to look elsewhere.
AnkiDroid is free on Android. The iOS version costs $24.99. This creates a meaningfully different calculus for Android users considering Quizlet Plus. You are not choosing between a $35 subscription and a $25 app - you are choosing between a $35 subscription and a free one. AnkiDroid's algorithm is objectively better for long-term retention than anything in Quizlet's free or paid tier. The trade-off is setup time and interface complexity. But if you are willing to spend a couple of hours learning AnkiDroid, you are unlikely to go back to paying for Quizlet.
The content library is Quizlet's real moat. Hundreds of millions of pre-made decks covering almost every textbook chapter in common use. For a student who needs to start studying tonight and has no time to create cards from scratch, searching Quizlet for their specific textbook is often faster than any alternative. Gridually has quiz content built in and is adding community decks. AnkiDroid has a shared library but it requires more hunting. If pre-made content is your primary need and you are studying mainstream subjects, Quizlet's free tier is still worth keeping installed alongside whatever else you use.
Android users should exhaust the free options before paying for Quizlet Plus. AnkiDroid is free and algorithmically superior. Gridually is free and easier to use daily. Quizlet earns its place on Android as a content library, not as a study tool, and the free tier is sufficient for that purpose. Gridually's spatial encoding is based on memory research from the University of Chicago, University of Bonn, and Macquarie University.
AnkiDroid is completely free and open-source with full Anki functionality. Gridually offers a free tier with spatial memory grids and no ads. Both are strong free options. AnkiDroid is more powerful but harder to set up. Gridually is easier to start with and uses a different learning approach.
Yes. AnkiDroid is free and open-source on Android. Unlike the iOS version (which costs $24.99), the Android app is maintained by volunteer developers and costs nothing. It has full Anki functionality including add-on support.
AnkiDroid has complete offline functionality for free. Gridually supports offline study on its free tier. Quizlet requires Plus ($7.99/month) for offline access on Android.
