Most “best quiz app for students” lists are written by people who haven’t sat an exam in a decade. They pick whichever apps the publisher has affiliate deals with, ignore whether the app actually helps you retain anything, and rate by feature count instead of by what works in a revision session. This guide is the opposite of that — it ranks twelve quiz apps on the questions that matter when you’re preparing for a real exam: does it support active recall (the single most-replicated finding in cognitive psychology of learning), does it support spaced practice (the second), does the free tier let you actually study, and how badly does the ad load break concentration during a 25-minute revision block.

The short version: the right quiz app depends on what you’re studying, how much you’ll pay, and whether you’re trying to memorise facts or genuinely understand concepts. The longer version is below.

Disclosure. MojQuiz publishes this article. Our own platform is included in the comparison for completeness — judge that entry accordingly. Editorial standards including how we pick and test the apps are documented in our editorial standards page.

How we tested

We picked twelve apps that show up most consistently in student forums (Reddit’s r/GetStudying, r/medicalschool, r/Anki communities; Discord study servers; the IRC channels that still run for older subject communities) and tested each against five criteria over a four-week revision sprint in May 2026.

  1. Retention impact, weighted heaviest. Does the app push you toward active recall (you generate the answer) rather than passive review (you read and nod)? Does it support spaced repetition or at least rough re-test intervals? Roediger and Karpicke’s 2006 Science paper on the testing effect found students who self-tested retained about 61% of material a week later, versus roughly 40% for those who reread. Cepeda et al. (2008) showed spaced practice consistently beats cramming. The apps that score well here are built around those two findings.

  2. Free-tier depth. A free tier that caps you at 10 questions a day is functionally a paywall. We checked daily limits, locked categories, watermark / nag screens, and whether you can actually finish a revision unit without subscribing.

  3. Ad load on the free tier. Banner is fine. Mid-screen video interstitial every 3 questions is concentration-breaking. We graded this on a 1–5 scale where 5 is “barely noticed” and 1 is “I switched to my notes.”

  4. Subject coverage for what students actually need: general knowledge, sciences, maths, history, English / literature, current affairs, competitive-exam prep (UPSC, SSC, GRE, GMAT, SAT, A-Levels, IB).

  5. Cross-device sync. Most students revise across phone, tablet, and a browser. Apps that lose your progress between devices got marked down.

We did not weight UI polish or onboarding. They matter at the margins; they’re not why students keep an app open through a four-month revision cycle.

The twelve apps, ranked

1. Anki — Best for serious long-term retention

Free on Android and desktop. Paid on iOS (around US$25 one-time). Anki is not strictly a “quiz app” — it’s a spaced-repetition flashcard system — but it does what every other app on this list claims to do, only better. The algorithm (SM-2, an open-source variant of SuperMemo’s algorithm from the 1990s) genuinely schedules cards at intervals matched to how confident you were on the previous review. Five years into med school, this is the only revision tool many students still use.

Use it if: you’re committing material for the long term — vocabulary, anatomy, formulas, dates, named studies in a science discipline. The 600,000+ shared decks (search AnkiWeb) cover most major exams.

Don’t use it if: you want polish. Anki looks like it was last redesigned in 2009. The friction is real for the first week; after that, you stop noticing.

Free tier: unlimited on Android, web, and desktop. iOS app is a one-time purchase that funds development across all platforms.

Ads: none. Anki is built and maintained by a small team funded by the iOS purchase price.

2. Quizlet — Best for vocabulary and quick definition recall

Free with ads / Quizlet Plus US$36/year. Quizlet’s strength is breadth — somewhere around 500 million user-generated study sets, which means almost any course at any university has at least one half-decent deck already. Its “Learn” and “Test” modes nudge you toward active recall rather than passive review, which puts it ahead of most flashcard apps.

Use it if: you’re learning vocabulary, definitions, named items in a list (countries, periodic table, kings of England), or anything where there’s a clear question-and-answer pair.

Don’t use it if: you want fine-grained spaced repetition. Quizlet’s spacing is less granular than Anki’s and the Pro features that improve it cost money.

Free tier: full study mode access, with ads. Some features (advanced study modes, custom Learn paths) are Plus-only.

Ads: banner + occasional interstitial. Tolerable for short revision bursts.

3. Brainscape — Best for the spaced-repetition curious who can’t stomach Anki

Free with limits / Pro US$10/month or US$80/year. Brainscape is what Anki would look like if a designer touched it. The “Confidence-Based Repetition” algorithm is a simplified spaced-repetition system that asks you to rate how well you knew the answer on a 1–5 scale; the app schedules accordingly. Less powerful than Anki’s SM-2 but considerably easier to start using.

Use it if: you want spaced repetition without the Anki learning curve. The pre-made decks for MCAT, USMLE, SAT, and a handful of European university exams are well-maintained.

Don’t use it if: you’re on a tight budget — the free tier is genuinely limiting on the number of decks you can study at once.

Free tier: restricted — caps the number of “active” decks. Designed to convert you.

Ads: none on either tier. (Brainscape monetises via Pro subscription only.)

4. RemNote — Best for STEM students who want notes and recall in one app

Free with limits / Pro US$96/year for students. RemNote is a notes app that runs spaced-repetition flashcards on the same content — write your notes once, mark concepts with the special syntax, and they become testable cards automatically. The killer feature for STEM students is LaTeX support in cards: chemistry formulas, mathematical notation, physics equations all render correctly during review.

Use it if: you take detailed digital notes during lectures and want to convert those notes into testable material without rewriting everything as flashcards.

Don’t use it if: you prefer paper notes or already have a settled note-taking workflow (Notion, Obsidian, OneNote) — RemNote wants you in its ecosystem.

Free tier: generous for individuals. The Pro tier unlocks bigger PDF imports and integrations.

Ads: none.

5. Khan Academy — Best for working through unfamiliar material

Completely free. No paid tier. Khan Academy doesn’t really fit a quiz-app comparison, but it’s where most students under-use one of the strongest free study tools available. Its mastery-based question sets sit alongside short video explanations, so when you get a question wrong you can immediately see why — not just the answer. The maths, sciences, and US history coverage is exceptionally well-maintained.

Use it if: you’re encountering material for the first time, or returning to it after a break. The combination of explanation + practice is rare and effective.

Don’t use it if: you’ve already mastered the material and want fast recall practice — Khan’s pace is built for learning, not drilling.

Free tier: the whole thing. Khan Academy is a non-profit funded by donations and grants.

Ads: none.

6. Sporcle — Best for general knowledge and the “I want to learn while having fun” hour

Free with ads / Sporcle Group / Party US$5–10/month. Sporcle has been running since 2007 and remains the canonical general-knowledge quiz site. The strength is range — millions of user-made quizzes across maps, history, sports, literature, music, and the kind of niche pub-quiz fodder you can’t find compiled anywhere else. The “type the answer” format pushes active recall harder than multiple choice.

Use it if: you’re broadening general knowledge for a competitive exam (UPSC, civil service papers, current affairs sections of bank exams), preparing for a quiz competition, or just want quizzing as a study break that doesn’t feel like wasted time.

Don’t use it if: you’re memorising for a specific syllabus — Sporcle is too broad. Use it as a complement to syllabus-focused tools.

Free tier: full access with display ads.

Ads: banner + video on mobile. The desktop site is the cleaner experience.

7. Kahoot! — Best for group revision and study circles

Free for personal use / Kahoot!+ from US$3/month. Kahoot! is built around live group quizzes — the “type a PIN” game-show format that’s spread through classrooms worldwide. For revision, its strength is social: forming a study group of 3–5 students and racing through past-paper questions is genuinely effective, both for the testing effect and for the desirable-difficulty mechanism of competing under time pressure.

Use it if: you have a study group. Solo mode exists but loses most of what makes Kahoot! distinctive.

Don’t use it if: you’re studying alone. The free tier doesn’t really support sustained individual revision, and Kahoot!+ is priced for educators not students.

Free tier: unlimited hosting of personal games, with branded ads.

Ads: light. Branded “sponsored question” inserts are the main pattern.

8. UPSC Pathshala / Adda247 / Testbook — Best for Indian competitive exam prep

Tiered free + paid. Pricing varies. These three are the dominant apps for UPSC, SSC, banking, RBI, NEET, JEE, and state-level competitive exams in India. We can’t rank them against each other meaningfully because the right one depends on which paper you’re sitting and which mock-test series your coaching institute prefers. The pattern is similar across all three: free daily practice quizzes, paid mock-test series, paid live classes.

Use it if: you’re preparing for any major Indian competitive exam — current affairs sections especially are updated daily with the kind of fresh material no general-purpose quiz app provides.

Don’t use it if: you’re outside the Indian exam system. The targeting is too specific.

Free tier: daily practice quizzes + a few mock tests.

Ads: banner + interstitial on free tier. Reasonable.

9. MojQuiz — Best for low-friction, low-cost, daily-habit general knowledge

Web is free. Mobile app launching in 2026 (free with optional ad removal). Disclosed conflict: we publish this guide. Our own platform sits in the casual / general-knowledge category — 13 topics with 100 questions per difficulty level, no signup, free to play, and a 10-question round structure that fits inside a study break. We’re not the right tool for syllabus-focused exam prep (use Anki or the regional apps above for that). We are useful if your goal is to build a daily general-knowledge habit alongside your main revision, or as a 10-minute palate-cleanser between concentrated study blocks.

Use it if: you want a daily-quiz habit that takes five minutes and requires zero setup, or you’re preparing for the general-awareness section of a competitive exam and want broad-base trivia drilling.

Don’t use it if: you need spaced repetition, deep syllabus coverage, or the ability to upload your own notes.

Free tier: the whole site.

Ads: none on the web. The forthcoming mobile app will be ad-supported on the free tier with an IAP option to remove ads.

10. QuizUp — Worth checking the resurrection (but not yet)

Status uncertain in 2026. QuizUp was the iconic competitive quiz app from the mid-2010s before it shut down. A small team has been working on a revival. We won’t include a verdict here because the relaunch state changes month to month — check before committing time.

11. Memrise — Best for language learners specifically

Free with limits / Pro US$60/year. Memrise specialises in language vocabulary using native-speaker video clips and spaced repetition. The general-knowledge content is shallow; the languages content is excellent. If your “revision” is a foreign language, Memrise belongs in your toolkit.

Free tier: restricted course access; full vocabulary review requires Pro.

Ads: minimal on free tier.

12. The Princeton Review / Magoosh / Kaplan exam-prep apps — Best when the exam dictates the app

Pricing varies by exam and tier. GRE, GMAT, SAT, ACT, LSAT — each has a dominant prep-app company whose question banks are closest to the real exam style. Magoosh is the best-value of the three for GRE / GMAT verbal. Kaplan and Princeton Review run heavier in mock-test infrastructure but cost more.

Use them if: you’re sitting one of these standardised tests. The official practice content is hard to substitute.

Don’t use them if: you’re not sitting that specific test. The general-knowledge value is low.

How a student should actually use these

A common mistake is downloading three quiz apps and using each for ten minutes a day. Splitting your revision across multiple apps fragments the spaced-repetition signal — Anki cannot schedule a card it never saw, Quizlet cannot tell you that you nailed the same concept on Brainscape yesterday. Pick one tool for spaced repetition and stick with it.

A workflow that holds up across most students we’ve spoken to:

  1. One spaced-repetition app for the material you must retain long-term. Anki for hard mode; Brainscape or RemNote for easier ramps. This is your main investment, 20–40 minutes a day during a revision sprint.

  2. One subject-specific app if your exam has one — Indian competitive-exam apps, GMAT / GRE / SAT prep apps, Khan Academy for catching up on first-time material. 20–30 minutes a day.

  3. One general-knowledge app for breadth, played in study breaks. Sporcle, MojQuiz, or whatever fits a five-minute slot. Not a replacement for revision — a habit alongside it.

Across all three: the testing effect (Roediger and Karpicke, 2006) only works if you actually retrieve answers from memory rather than recognising them. Cover the answer, generate from memory, then check. If the app supports “type the answer” or open-ended modes, prefer them over pure multiple choice.

Frequently asked questions

Is there a single best quiz app for students? No — it depends on what you’re studying. For long-term retention of factual material, Anki is the conventional answer and the research backs it. For vocabulary, Quizlet. For general knowledge habits, Sporcle or MojQuiz. For specific standardised tests, the test publisher’s own app.

Are free quiz apps actually good enough for serious revision? For most students, yes. Anki (free on Android / web / desktop), Khan Academy (free), and Brainscape’s free tier together cover most revision needs without spending anything. The paid tiers help at the margins; they’re not load-bearing.

Which quiz app is best for competitive exam preparation in India? For UPSC, SSC, banking, RBI, NEET, and JEE, the Indian-market apps (Adda247, Testbook, UPSC Pathshala among the largest) are purpose-built and updated daily with current affairs. Pair them with Anki for the static material — formulas, named studies, history dates — and Khan Academy for any maths or science topic you need to first understand before drilling.

How long should I spend on quiz apps each day during revision? A reasonable cap is 60–90 minutes total across all quiz / flashcard tools, split into 25-minute focused blocks. Beyond that you’ll see diminishing returns — Cepeda et al.’s (2008) work on spacing shows that distributing the same total time across more days outperforms longer single sessions.

Do quiz apps work better than re-reading notes? Yes — consistently and by a wide margin. Roediger and Karpicke’s 2006 study found self-testing produced retention around 61% versus 40% for re-reading the same passages. The effect has been replicated hundreds of times. If your only choice is “play 20 minutes of a quiz” or “re-read 20 minutes of notes,” play the quiz.
