What is the best quiz app in 2026? For most people the best quiz app is Quizlet (studying), Kahoot! (groups and classrooms), or Sporcle (trivia depth). The best free quiz app with no signup or download is MojQuiz, our own web platform.

Why trust this guide. Published by MojQuiz — we make a free web quiz platform of our own, so we have a horse in this race, and we say so up front. MojQuiz is kept out of the ranked list and reviewed separately at the end.
How we tested. Each of the 13 platforms got at least one full play session per category, on the free tier, on both iOS and Android where a native app exists. We weight our verdicts roughly: question quality 30%, free-tier usability 25%, breadth of content 20%, ad and paywall friction 15%, cross-platform availability 10%.
How we verify. Store ratings and review counts are pulled from live Google Play listings rather than quoted from memory, and re-checked on each update. Where we could not verify a figure, we leave it out rather than estimate. Apps that have shut down are removed from the ranking and recorded in the discontinued section below.
Author. By Anu Sawhney, editor of MojQuiz, who has built and maintained a 3,900-question quiz library across 13 categories. Our full editorial standards explain how we test and correct.

The 13 best independent quiz platforms reviewed
1. Kahoot! — ★★★★
Price: Free (Basic) / $3–10/month (Premium) · Platforms: Web, iOS, Android · Google Play: 4.74 from 855,462 ratings · Try: kahoot.com
The go-to platform for teachers and trainers. Kahoot! excels at group learning with its game-show format and live competitions.
Pros: Excellent for classrooms · Engaging multiplayer format · Easy quiz creation · Huge question library
Cons: Requires a host for games · Limited solo play · Premium features get costly fast
Best for: Teachers, corporate training, group events.
2. Quizlet — ★★★★★
Price: Free / $8/month (Plus) · Platforms: Web, iOS, Android · Google Play: 4.69 from 901,956 ratings · Try: quizlet.com
More than just flashcards. Quizlet offers multiple study modes including tests, matching games, and spaced repetition for optimal learning.
Pros: Millions of study sets · AI-powered learning modes · Multiple study modes · Great for exam prep
Cons: Not focused on trivia · Ads on free version · Can be overwhelming for casual use
Best for: Students, language learners, exam preparation.
3. Trivia Crack — ★★★★
Price: Free (with ads) · Platforms: iOS, Android · Google Play: 4.48 from 7,873,063 ratings · Try: triviacrack.com
The most-rated trivia app in this guide by a wide margin — nearly 7.9 million Google Play ratings. Challenge friends or random opponents across six categories.
Pros: Fun competitive gameplay · Strong social features · Regular content updates · Global player base
Cons: Heavy on ads · Energy system limits play sessions · Questions can get repetitive
Best for: Casual trivia fans and competitive players.
4. Sporcle — ★★★★
Price: Free / $5/month (Orange) · Platforms: Web, iOS, Android · Google Play: 4.46 from 2,827 ratings · Try: sporcle.com
The trivia enthusiast’s paradise with over 1 million user-created quizzes covering every topic imaginable.
Pros: Massive quiz variety · Unique quiz formats · Active community · Daily challenges
Cons: Dated interface · Quality varies (user-generated) · Ads on free version
A note on that rating count. Sporcle’s Android app has only 2,827 ratings — orders of magnitude below others here. That reflects where its audience actually is: Sporcle is a web-first platform with a two-decade-old browser community, and the mobile app is a late, secondary surface. We rank it on the strength of the quiz library, which is the best in this list, not on app-store popularity.
Best for: Trivia purists and niche-topic enthusiasts.
5. Brainscape — ★★★★★
Price: Free (Basic) / Pro $19.99 month-to-month, $9.99/mo billed per semester ($59.94), or $7.99/mo billed annually ($95.88) — lifetime $199.99 · Platforms: Web, iOS, Android · Google Play: 4.67 from 13,610 ratings · Try: brainscape.com
Uses cognitive science and spaced repetition for maximum retention. Ideal for serious learners. Note the wide spread between billing terms: paying month-to-month costs two and a half times the annual rate, so this is only good value if you commit for a year or take the lifetime option.
Best for: Medical students, language learners, certification prep.
6. Lumosity — ★★★★
Price: $12/month · Platforms: Web, iOS, Android · Google Play: 4.79 from 318,588 ratings · Try: lumosity.com
Brain training games backed by neuroscience research, focusing on memory, attention, and problem-solving. Worth noting: at 4.79 this is the highest-rated app in this guide on Google Play. We rank it lower than that score alone would suggest because it is subscription-only with no meaningful free tier, and it is brain training rather than quizzing proper.
Best for: Cognitive improvement, seniors, brain health.
7. Duolingo — ★★★★★
Price: Free / $7/month (Super) · Platforms: Web, iOS, Android · Google Play: 4.73 from 47,253,509 ratings · Try: duolingo.com
Primarily a language app, but Duolingo’s gamified quiz format makes it one of the best learning platforms available. With over 47 million ratings it is comfortably the most-reviewed app in this guide.
Best for: Language learning and building daily practice habits.
8. Jeopardy!® Trivia TV Game Show — ★★★★
Price: Free (with ads) · Platforms: iOS, Android · Google Play: 4.37 from 169,311 ratings
Official Jeopardy! game with daily challenges and authentic gameplay experience. Formerly published as Jeopardy! World Tour — if you are looking for that title, this is the same game under its current name.
Best for: Jeopardy! fans and general knowledge enthusiasts.
9. Brilliant — ★★★★★
Price: $25/month · Platforms: Web, iOS, Android · Google Play: 4.51 from 110,998 ratings · Try: brilliant.org
Interactive problem-solving platform for STEM subjects with guided courses and daily challenges.
Best for: Math, science, and computer science learners.
10. Memrise — ★★★★
Price: Free / $9/month (Pro) · Platforms: Web, iOS, Android · Google Play: 4.42 from 1,571,797 ratings · Try: memrise.com
Language learning through video clips of native speakers and spaced repetition quizzes.
Best for: Practical language learning and vocabulary building.
11. Peak — ★★★★
Price: Free / $5/month (Pro) · Platforms: iOS, Android · Google Play: 4.35 from 516,014 ratings · Try: peak.net
Brain training with 40+ games designed by neuroscientists and game experts.
Best for: Cognitive training and mental fitness.
12. Trivia Plaza — ★★★
Price: Free · Platforms: Web only (browser) · Try: triviaplaza.com
A browser-based trivia site with a large library of questions across 16 categories. No login, instant scoring, and it loads fast on a phone browser.
Note on platforms: Triviaplaza is a website, not a mobile app — there is no official Android or iOS app. An unrelated iOS app called Movie Trivia Plaza exists, but it is a separate, much narrower product and not the site reviewed here.
Best for: Quick trivia sessions in a browser, with no install.
13. QuizWhizzer — ★★★
Price: Free (with ads) · Platforms: Web only (browser) · Try: quizwhizzer.com
Classroom-focused quiz platform where players move avatars along a custom game board as they answer. Web-only by design; there is no native mobile app.
Best for: Creating custom gamified quizzes for teachers.
Discontinued — no longer available
We keep shut-down apps on record rather than quietly deleting them, so that 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, and at its peak it had over 20 million users. It was removed from the App Store on 20 January 2021, and its servers were taken offline on 24 March 2021, making the app and web service permanently inaccessible. Owner Glu Mobile cited persistent monetisation problems — high engagement that never translated into revenue.
If you liked QuizUp, try instead: Trivia Crack for the same head-to-head social format, or MojQuiz for fast solo rounds with no signup.
Publisher’s own pick: MojQuiz
Full disclosure: MojQuiz is the platform that publishes this guide. We’ve kept it out of the ranked list above to stay honest. Here’s the entry for completeness, judge it on its own merits.
MojQuiz — Free, no signup
Price: Free on web · Android app free, ad-supported, with optional in-app purchases from $0.49 · Platforms: Web (PWA), Android · Try: mojquiz.com or Google Play
A clean web experience with curated questions across 13 major categories. Each category features three difficulty levels with a deep pool of hand-picked questions. Since this guide judges other apps on ad load and paywalls, ours: the web version carries a single display slot on long-form pages, and the Android app is ad-supported on the free tier with a one-time purchase to remove ads and unlock premium content.
The Android app. Listed on Google Play as MojQuiz — Daily Trivia Quiz, published by METAFLARE INTERACTIVE LLP. It carries the same 3,900-question library as the site across the same 13 categories, and adds three things the web version does not have: the full question bank downloaded for offline play, streaks and XP that persist between sessions, and level history backed by an account you never have to create — play starts anonymously. The Play listing is flagged “Contains ads” and “In-app purchases,” which is accurate: the free tier shows ads, and the paid items run $0.49–$3.99 for ad removal and premium content. There is no free trial to expire and no subscription.
Pros: No account required · Full question bank free on web · Works offline (PWA and Android) · Streaks and XP in the Android app · Clean, fast interface
Cons: No multiplayer mode yet · No iOS app · Android app is ad-supported unless you pay to remove them · Android app is new, so it has no review history or store rating yet · Questions are updated manually rather than on a schedule
Best for: Quick zero-friction play. Strong for mathematics, geography, literature, and general knowledge.
Why it is not in the ranked list. We publish this guide, so scoring ourselves against apps we also score would be worth nothing to you. The entry above is here so the list is complete and so the disclosure is unavoidable rather than buried — not to claim a position. Our own rating is deliberately omitted; the app has no store rating yet either, so there is nothing to check us against, and we would rather say that than invent a number.
How to choose the right quiz app
Consider these factors when picking a platform:
- Purpose: Learning vs. entertainment vs. exam prep
- Budget: Free vs. paid features you’d actually use
- Content quality: Expert-created vs. user-generated
- Platform: Mobile, web, or both
- Social features: Solo vs. multiplayer preferences
- Ad experience: Your tolerance for interruptions
- Offline access: Important for commuters and travelers

Best free quiz apps
If price is the deciding factor, the strongest free quiz apps in 2026 are:
- MojQuiz on web — completely free, no signup, no download, no paywalls. Best for zero-friction play. (The Android app is also free to play, but it is ad-supported with optional purchases — so we count the web version, not the app, as the genuinely unrestricted one.)
- Sporcle (free tier) — over a million user-made quizzes; ads on free.
- Kahoot! (Basic) — free for group games, though the best features are paid.
- Quizlet (free) — full study modes on the free tier, with ads.
For pure “play now and pay nothing,” MojQuiz on the web wins because there’s no account wall and no download step — you’re one tap from a general knowledge or science round. If you want the same questions offline on a phone, the Android app is the version to install.
Best general knowledge quiz apps
For general knowledge specifically — pub-quiz-style breadth across history, geography, science, sport and current affairs — the standouts are MojQuiz (13 curated categories, three difficulty levels), Sporcle (deepest niche-topic library) and Trivia Crack (casual, competitive). MojQuiz is built around GK: try general knowledge, history, or geography.
Best trivia apps for 2026
For entertainment-first trivia rather than studying, the best apps this year are Sporcle (variety), Trivia Crack (social, competitive, 4.48 from 7.9M Google Play ratings) and Jeopardy!® Trivia TV Game Show (classic format, formerly Jeopardy! World Tour). QuizUp used to be the pick for 1v1 duels, but it shut down in 2021. Prefer to play straight in a browser with no download and no account? Play entertainment, music or sports trivia free on MojQuiz.
Just want to start playing? No downloads, no accounts — jump into a quiz: Science, History, General Knowledge.
