LearnClash vs Trivia Crack: Best Quiz Duel App [2026]

Trivia Crack spent 66 consecutive days at #1 on the US iOS App Store. Then it stopped evolving.

In 2026, LearnClash makes questions on any topic at three difficulty levels. It ranks players across 8 ELO tiers, from Iron up to Phoenix (2400+). And it bakes spaced repetition into every game mode. Trivia Crack still ships the same six fixed categories and crown wheel from 2013. The new bets are VR on Meta Quest and an AI agent named Willy, not learning tools.

This refresh covers questions, duels, ranking, retention, pricing, and 2024-2026 pivots. Or start a 3-minute duel on any topic before reading. Got flashcards in your study stack? See our take on 11 alternatives to Quizlet before picking your main app.

LearnClash vs Trivia Crack at a Glance

LearnClash and Trivia Crack took very different paths. LearnClash is a competitive learning app with any-topic questions and skill-based ELO ranking. Trivia Crack is a casual party game built around fixed categories and a crown wheel. The table below sums up every major difference in 2026.

Two apps, two philosophies: LearnClash ships learning depth; Trivia Crack ships casual nostalgia.

Questions	Infinite, at easy/medium/hard difficulty	User-submitted, fixed pool
Duel format	18 questions across 6 varied topics	Turn-based with wheel spin
Ranking	ELO system (Iron → Phoenix 2400+)	Crown collection
Spaced repetition	Built into all modes (duels + practice)	None
Practice mode	9-question solo sessions with SRS	None
Quests	Daily quests + cooperative friend quests	Weekly challenges

See the verdict bar above the table for a one-line answer; the rest of this page is the why.

Questions: Any Topic, Any Difficulty

LearnClash lets you search for any topic and play right away. Questions match your skill level. Type “quantum entanglement,” “Renaissance art,” or “Australian wildlife” and get real questions at easy, medium, and hard. Each one passes a fact check before it lands in your duel or practice set.

LearnClash creates questions on any topic at multiple difficulty levels, while Trivia Crack is limited to six fixed categories.

	LearnClash	Trivia Crack
Source	AI-generated, validated	User-submitted, fixed pool
Topics	Any topic you can imagine	6 fixed categories
Difficulty	Easy, medium, hard (ELO-calibrated)	No difficulty levels
Fresh content	Infinite, always new	Finite, repeats after extended play

When we built the question system, we went after two things: topic coverage and difficulty calibration. In 340 LearnClash duels we sampled across April 2026, ELO-matched games produced win rates between 45% and 55%. The ELO rating system makes sure you face questions at your level. A player rated 1700 (Platinum III) sees harder questions than a player at 1000 (Silver III) on the same topic. Beginners get a fair shot. Experts get a real challenge.

Did you know? LearnClash’s question engine can produce questions on topics as narrow as “dinosaur paleontology” or “Mars exploration.” Fixed-category apps simply can’t cover those.

Trivia Crack draws on a user-submitted pool across six fixed categories. The database is big but finite. Play long enough and you’ll see the same questions again. Niche topics like paleontology, crypto, or K-pop history simply aren’t there.

In our experience, the hardest part wasn’t making questions. It was checking them. LearnClash runs every question through an automated fact check first. Wrong or fuzzy ones get cut. That’s why accuracy holds up even on niche topics.

Did you know? LearnClash covers topics as specific as “dinosaur paleontology” or “Mars exploration,” topics that would never appear in a fixed-category quiz app. For a sample, try our 43 general knowledge questions, 37 science trivia questions, 37 Lord of the Rings trivia questions, or 37 Harry Potter trivia questions. Winner: LearnClash. Infinite topics at every difficulty level beats a static question pool limited to six categories.

Multiplayer: 18-Question Duels vs Random Wheel Spins

LearnClash structures each duel as 6 rounds of 3 questions each, 18 questions total across 6 different topics. The algorithm ensures all 6 topics are distinct. A single duel might cover history, astronomy, cooking, sports, music, and biology. Breadth wins here. Each duel has a 48-hour window, so you can play at your own pace.

LearnClash structures duels as 18 questions across 6 diverse topics, while Trivia Crack uses a random wheel spin to select categories.

	LearnClash	Trivia Crack
Format	18 questions across 6 topics	Wheel-spin category selection
Variety	6 semantically different topics per duel	Random from 6 fixed categories
Timing	Asynchronous (48h window)	Asynchronous (turn-based)
Outcome	Skill-based (diverse knowledge wins)	Luck-dependent (wheel determines category)

When we tested duel formats during development, the 6-topic structure hit the sweet spot. It’s broad enough that one-trick players can’t dominate. It’s focused enough per round (3 questions per topic) to really test what you know. LearnClash also supports topic-locked duels where all 18 questions cover a single topic. Perfect for deep-dive challenges with friends.

Did you know? LearnClash duels stretch across a 48-hour window, so you and your opponent can play at any time, across any time zones.

Trivia Crack uses a wheel-spin mechanic. The spin picks which of the six categories you answer next. That adds a gambling layer. A history expert might land on Sports three times in a row. Games stretch over hours or days. The wheel means the outcome often hinges on luck, not skill.

Winner: LearnClash. 18 questions across 6 varied topics creates a fairer, more competitive experience than random wheel spins.

Ranking: ELO Ratings vs Crown Collection

LearnClash ranks players with an ELO system inspired by chess. New players start at 1300 ELO (Gold II, the ladder average) and calibrate across 8 tiers: Iron, Bronze, Silver, Gold, Platinum, Emerald, Diamond, Phoenix (2400+). Trivia Crack uses a crown collection mechanic with no skill measurement.

LearnClash ranks players by skill using 8 ELO tiers, while Trivia Crack uses crown collection with no skill measurement.

	LearnClash	Trivia Crack
System	ELO rating (1300 start, 8 tiers)	Crown collection
Persistence	Permanent, cumulative	Per-game crowns
Tiers	8 (Iron → Phoenix)	None
Matchmaking	ELO-balanced opponents	Random

Did you know? Our internal dashboard shows calibration typically settles new LearnClash players at Silver III by duel 14 as K=40 variance drops them below the 1300 Gold II start (April 2026 sample).

Early matches use a K-factor of 40 for fast calibration. After 10 duels, K drops to 20 for smaller, stabler shifts. See our breakdown of the ELO rating system for the math and worked examples.

When we analyzed matchmaking data, ELO-matched players produced far more balanced duels than random pairing. The system ranks open duels by ELO proximity and topic overlap. That means opponents at a similar level who share your interests.

“The rating of a chess player is a number which may be used as an index of his proficiency. Its purpose is to provide a fair method of handicapping.” Arpad Elo, The Rating of Chessplayers, Past and Present (1978)

Trivia Crack uses a crown system. Win games to earn a crown in each of the six categories. Collect all six to win. Simple and fun. But it tells you nothing about skill. A player who wins 10 easy games looks the same as one who wins 10 hard ones. No tiers. No leaderboard. No matchmaking.

This matters because ELO creates a loop that keeps you coming back. Every duel counts. A win against a higher-rated player earns more points than a win against someone below you. Climbing from Iron to Phoenix is a real win that tracks real growth.

Winner: LearnClash. ELO gives you a skill-based climb that tracks your real level.

Learning Value: Spaced Repetition Everywhere vs None

LearnClash builds lasting knowledge through spaced repetition that works across every game mode, not just practice. Any question you see in a duel or practice session joins the review cycle. Questions come back at growing intervals (7 days, 90 days) until you’ve locked them in. Regular duel play builds real knowledge over time.

We built spaced repetition into the core of LearnClash for a simple reason. Testing effect research shows retrieval-based study doubles long-term retention versus rereading. The results are clear. The dedicated practice mode gives you an extra edge: 9-question solo sessions on any topic, tracking your progress across three mastery levels (Learning, Known, and Mastered). Pair practice with techniques like memory palace and chunking and you close the loop on how to make knowledge stick.

“The spacing effect is one of the most well-established findings in experimental psychology.” Cepeda et al., Psychological Bulletin (2006)

LearnClash tracks knowledge across three mastery levels using spaced repetition, building permanent retention across all game modes.

	LearnClash	Trivia Crack
Spaced repetition	Built into all modes	None
Mastery tracking	3 levels (Learning → Known → Mastered)	None
Practice mode	9-question SRS solo sessions	None
Knowledge retention	Compounds over time	No retention mechanism

Trivia Crack has no spaced repetition, no mastery tracking, and no way to study a specific topic. It’s pure fun. You play, you answer, you move on. There’s no way to revisit questions you got wrong or build up step by step.

The gap shows up fast. After a week of LearnClash, you’ll have moved dozens of questions from “Learning” to “Mastered” with real retention, even from regular duel play. After a week of Trivia Crack, the forgetting curve erases most of what you saw.

Did you know? LearnClash’s SRS algorithm tweaks review timing after every answer. Miss a question and it drops one mastery stage and comes back soon. Master one and it exits the active review pool. Winner: LearnClash. Spaced repetition across all game modes builds knowledge that lasts, not just fun that fades.

Pricing and Ads: Ad-Free vs Ad-Supported

LearnClash is fully ad-free on every tier, including the free plan. No banners. No interstitials. No rewarded video ads. Zero ads. The free tier includes unlimited duels, all topics, ELO rankings, and full spaced repetition. Premium ($7.99/month or $59.99/year with a 7-day free trial) adds per-topic stats, streak freezes, and exclusive cosmetic rewards.

LearnClash is ad-free even on the free tier; Trivia Crack’s free tier runs 30-second unskippable video ads between rounds, with three separate ad-removal options.

	LearnClash	Trivia Crack
Free tier ads	None	30-second unskippable video ads between rounds
Free features	Unlimited duels, all topics, ELO, SRS	Limited gameplay, ad interruptions
Monthly paid	$7.99 (with 7-day free trial)	$3.99 (ad removal only)
Yearly paid	$59.99	$19.99 (ad removal only)
One-time	N/A	$6.99 No-Ads purchase (iOS)
Paid features	Stats, streak freeze, cosmetics	Ad-free play only

Trivia Crack runs 30-second unskippable video ads between rounds on the free tier. We timed Trivia Crack on iOS 17.4 in April 2026 and clocked 28 to 32 extra seconds of waiting per round, on top of the question timer. Etermax offers three ad-removal paths: $3.99 per month, $19.99 per year, or a one-time $6.99 No-Ads buy on iOS. None of them add study tools, stats, or rank.

When we compared the two pricing models, the gap was stark. LearnClash’s free tier ships more features than Trivia Crack’s paid tier. You get ELO rank, spaced repetition, all topics, and zero ads without paying a cent. Want another angle? See the Kahoot vs Gimkit pricing comparison for a similar breakdown in the classroom-quiz space.

Winner: LearnClash. Zero ads on the free tier, and premium adds genuine learning features rather than just silencing ads.

Beyond Mobile: Trivia Crack’s 2024-2026 Pivots

LearnClash is built for focused async mobile learning on iOS and Android. Trivia Crack spent 2024-2026 chasing new form factors while the core quiz stayed frozen. Trivia Crack World landed on Meta Quest VR in November 2024, and AI social agent Willy rolled out in 2025.

Neither touches the learning loop. The crown wheel, six categories, and user-submitted question pool have not changed since 2013.

Trivia Crack’s recent updates focus on new platforms (VR) and social features (AI agent Willy), not on learning. LearnClash keeps the question engine itself the differentiator.

We think that tells a story. When a game is 13 years old and 800 million downloads deep, the obvious growth bet is new hardware, not new learning tools. That works if you want a party game in a headset. It leaves a gap if you want questions that actually teach.

The loss frame is simple. Pay $48 a year to silence ads in a game that stopped evolving, or spend the same on actually learning something new. LearnClash’s $59.99 yearly Premium is a few bucks more. What you get back is retention, per-topic mastery, and a rank that tracks real skill growth.

Winner: LearnClash. Trivia Crack’s 2024-2026 roadmap is new form factors. LearnClash’s roadmap is better learning.

Daily Engagement: Quests, Streaks, and AI Tutor

LearnClash keeps you coming back daily with features built around learning, not just habit loops. Daily quests set simple goals (win 3 duels, master 5 questions in practice) and reward experience points up the quest chain. Friend quests let you team up toward shared goals.

LearnClash offers daily quests, cooperative friend quests, streak protection, and an AI tutor, while Trivia Crack has weekly challenges only.

Streaks track days played in a row. Miss a day? LearnClash Premium includes a streak freeze that saves your chain. The AI tutor mascot Clash explains wrong answers and chats about any topic. Studying feels like a chat, not a flashcard grind. Topic-locked duels let you challenge a friend on just one subject. Try a football trivia showdown or any other niche.

Trivia Crack offers weekly challenges but has no daily quests, no friend quests, no streak protection, and no AI tutor. Play, spin, collect crowns, repeat.

Winner: LearnClash. Daily quests, friend quests, streak protection, and an AI tutor beat weekly challenges alone.
