The short answer. Sporcle for trivia depth, Kahoot! for groups and classrooms, Trivia Crack for head-to-head play with friends, and Quizlet if you want quizzes for studying. MojQuiz publishes this guide and makes a quiz app of its own, so we’ve left it out of the comparison. It’s disclosed at the end.

What is the best quiz app in 2026? There isn’t one winner. It depends on what you want the app for. For trivia, Sporcle has the deepest library and Trivia Crack is the best head-to-head game. For group play, Kahoot! is the standard. For studying, Quizlet is the most widely used. Revision is a different job from trivia, so it has its own guide: best quiz apps for students compares Anki, Brainscape, RemNote and others on active recall and spaced repetition.

Our interest. MojQuiz publishes this guide and makes its own quiz platform. It isn’t compared, rated or recommended anywhere in this article. It appears only in a labelled disclosure at the end.

How we judge. Each app is judged on its free tier, for the use case named. Verdicts are editorial and weigh question quality, free-tier usability, breadth of content, ad and paywall friction, and cross-platform availability.

How we verify. Store ratings and review counts come from live Google Play listings, and each row shows when we last checked it. We re-checked Kahoot!, Quizlet and Trivia Crack on 21 September 2026. The Sporcle and Jeopardy! figures are from 19 July 2026.

What we tested. On 21 September 2026 we played Sporcle and Trivia Plaza in a desktop browser without signing in, and checked the current pricing pages for Sporcle, Kahoot! and QuizWhizzer. The screenshots below are from those sessions. We haven’t re-tested Trivia Crack, Jeopardy! or Quizlet hands-on for this update. Their entries rely on their store listings and published pricing, and we say so where it matters. Where we can’t verify a figure, we leave it out instead of estimating. Apps that shut down are moved to the discontinued section.

Best trivia apps

Sporcle — ★★★★

Price: Free with ads / Sporcle Orange $3.99/month or $43.99/year · Platforms: Web, iOS, Android · Google Play: 4.46 from 2,827 ratings (July 2026) · Try: sporcle.com

The largest trivia library here, with over a million user-created quizzes on nearly every topic.

Pros: Huge quiz variety · Unusual quiz formats (maps, click-the-list, timed typing) · Active community · Daily challenges



Cons: Dated interface · Quality varies because quizzes are user-made · Ads on the free tier

What we found. We played Countries of the World (45.6 million plays) without an account. Typed answers were accepted and scored instantly against a 15-minute timer. On the free tier the page carried display ads above the quiz, beside it and in a banner along the bottom of the screen, with a “Remove Ads” button leading to the Orange membership. Orange removes ads and unlocks the Sporcle Games archive.

Sporcle’s free tier, played without an account, 21 September 2026. Note the ad slots around the quiz.

About that rating count. Sporcle’s Android app has only 2,827 ratings, far fewer than the other apps here. That’s because Sporcle is web-first: its community has been on the browser site for two decades, and the app came later. We judge it on its quiz library, not on app-store popularity.

Best for: Trivia purists and niche-topic enthusiasts.

Trivia Crack — ★★★★

Price: Free (with ads) · Platforms: iOS, Android · Google Play: 4.46 from 7,859,457 ratings (September 2026) · Try: triviacrack.com

The most-rated trivia app in this guide by a wide margin. You challenge friends or random opponents across six categories.

Pros: Fun competitive play · Strong social features · Global player base



Cons: Heavy on ads · An energy system limits how long you can play · Questions repeat over time

Best for: Casual trivia fans who want to play against someone.

Jeopardy!® Trivia TV Game Show — ★★★★

Price: Free (with ads) · Platforms: iOS, Android · Google Play: 4.37 from 169,311 ratings (July 2026)

The official Jeopardy! game, with daily challenges in the show’s clue-and-response format. It used to be called Jeopardy! World Tour. If you’re looking for that title, this is the same game.

Best for: Jeopardy! fans and general-knowledge players who like the game-show format.

Trivia Plaza — ★★★

Price: Free · Platforms: Web only (browser) · Try: triviaplaza.com

A browser trivia site with questions across 16 categories. It needs no login, scores you instantly, and loads fast on a phone browser.

What we found. We played the Mixed General Knowledge quiz (over a million plays). A round is ten multiple-choice questions with four options each, and there’s no account or signup step anywhere. The quiz page has ad slots, but the game itself is clean and fast.

Trivia Plaza, question 1 of 10, played without signing in, 21 September 2026.

About platforms: Trivia Plaza is a website, not a mobile app, and has no official Android or iOS app. There’s an unrelated iOS app called Movie Trivia Plaza, but it’s a separate, much narrower product.

Best for: Quick trivia in a browser, with nothing to install.

Best quiz apps for groups and classrooms

Kahoot! — ★★★★

Price: Free (Basic) / teacher plans from $3/month, billed annually · business plans (Kahoot! 360) from $19/month · Platforms: Web, iOS, Android · Google Play: 4.74 from 857,263 ratings (September 2026) · Try: kahoot.com

The go-to platform for teachers and trainers. One host runs a game-show quiz on a shared screen, and players answer live on their own phones.

Pros: Excellent for classrooms · Engaging live multiplayer format · Easy quiz creation · Large library of ready-made quizzes



Cons: Needs a host · Limited solo play · Player limits scale with the plan: the $3 teacher plan caps a game at 50 players, and larger groups need a higher tier

Best for: Teachers, corporate training, group events.

QuizWhizzer — ★★★

Price: Free / Pro $39/year · Platforms: Web only (browser) · Try: quizwhizzer.com

A classroom quiz platform where players move avatars along a custom game board as they answer. It’s web-only by design, with no native mobile app. Students join with a game code and a nickname, and don’t need an account.

Free vs. paid. The free plan allows unlimited quizzes but caps games at 30 players and supports text-only questions. Pro ($39/year) raises the cap to 100 players and adds image, video and audio questions, AI question generation and individual student results (pricing checked 21 September 2026).

Best for: Teachers building custom game-style quizzes.

Best quiz app for studying

Quizlet — ★★★★★

Price: Free / Plus about $8/month (not re-checked for this update) · Platforms: Web, iOS, Android · Google Play: 4.68 from 914,924 ratings (September 2026) · Try: quizlet.com

More than flashcards. Quizlet’s Learn and Test modes push you toward active recall, and there are user-made study sets for almost any course.

Pros: Enormous library of study sets · Several study modes · Good for vocabulary and definitions



Cons: Not built for trivia · Ads on the free tier · The better spaced-repetition features are paid

Best for: Students, language learners, exam preparation.

If studying is your main goal, Quizlet is only the starting point. Our best quiz apps for students guide compares eleven revision tools, including Anki, Brainscape and RemNote, on retention, free-tier depth and ad load.

Often listed, but not quiz apps

Other “best quiz app” lists often include Duolingo and Memrise (language learning), Lumosity and Peak (brain training) and Brilliant (STEM courses). They’re good at what they do, but they aren’t quiz apps, so we don’t rank them here. If you’re considering a brain-training subscription, first read what the research says about brain training. People get better at the games they practise, but there’s little evidence the gains carry over to everyday abilities.

Discontinued — no longer available

We keep shut-down apps on record instead of quietly deleting them, so anyone searching for an old favourite gets a straight answer.

QuizUp — discontinued in 2021

Status: Shut down. Do not download.

QuizUp was a social trivia game with 1,200+ topics and real-time 1v1 multiplayer. At its peak it had over 20 million users. It was removed from the App Store on 20 January 2021, and its servers went offline on 24 March 2021, so the app and web service are permanently gone. Its owner, Glu Mobile, cited persistent monetisation problems: engagement was high but never turned into revenue.

If you liked QuizUp, try instead: Trivia Crack for the same head-to-head social format, or Sporcle for topic depth.

How to choose the right quiz app

Things to weigh when picking a platform:

  • Purpose: trivia for fun, a group game, or studying
  • Budget: free vs. paid features you’d actually use
  • Content quality: expert-written vs. user-generated
  • Platform: mobile, web, or both
  • Social features: solo vs. multiplayer
  • Ad load: how much interruption you’ll put up with
  • Offline access: matters for commuters and travellers

Best free quiz apps

If price decides it, these are the strongest free options:

  • Trivia Plaza. Free in the browser, no login, nothing to install.
  • Sporcle (free tier). Over a million user-made quizzes, with ads.
  • Kahoot! (Basic). Free for group games, though the best features are paid.
  • QuizWhizzer (Free). Unlimited quizzes for up to 30 players, text-only questions.
  • Quizlet (free). Full study modes on the free tier, with ads.
  • Trivia Crack. Free to play but ad-heavy, and an energy system limits sessions.

Best general knowledge quiz apps

For pub-quiz-style breadth across history, geography, science, sport and current affairs, the standouts are Sporcle (the deepest topic library), Trivia Crack (casual and competitive) and Jeopardy!® Trivia (a classic format that rewards broad general knowledge).

Disclosure: our own app

MojQuiz publishes this guide and makes its own quiz platform. We don’t rate or rank it here, because scoring ourselves against apps we also score would tell you nothing. This section exists so the conflict is stated plainly.

MojQuiz is a trivia site with questions in 13 categories at three difficulty levels. It’s free to play in a browser with no account. There’s also an Android app, MojQuiz — Daily Trivia Quiz, which adds offline play, streaks and XP. The app is ad-supported and offers optional in-app purchases ($0.49–$3.99) to remove ads and unlock premium content. It’s new, so it has no store rating yet, and there’s no iOS app or multiplayer mode.

Conclusion

The best quiz app is the one that fits what you want to do:

  • Best for trivia depth: Sporcle
  • Best for head-to-head play: Trivia Crack
  • Best for groups and classrooms: Kahoot!
  • Best for studying: Quizlet, or the tools in our students guide

Most have free tiers, so trying a few costs nothing. For running your own game, see the quiz night hosting guide and our trivia questions collection.
