Best QuizUp Alternative in 2026: Sway, LearnClash, Compared

100 million downloads. More than $40 million raised. Zero revenue model. QuizUp had everything except a future.

The best QuizUp alternative in August 2026 is LearnClash: topic-based 1v1 quiz duels with an 8-tier ELO ranking system, 3-stage spaced repetition built into every mode, and zero ads on any tier. QuizUp was the fastest-growing iOS game ever but shut down in March 2021. The original QuizUp team shipped a spiritual successor called Sway on the App Store in May 2025, and a separate unaffiliated app titled “QuizUp - The Game” appeared the same year. Neither has what LearnClash has: skill-based ranking married to retrieval-practice memory.

QuizUp was a topic-based 1v1 trivia duel app that ran from November 2013 to March 2021 and reached 100 million downloads before shutting down without a working business model. A QuizUp alternative in 2026 means an app built on the same loop, short quiz duels on topics you pick, and there are three live candidates: Sway, “QuizUp - The Game”, and LearnClash.

We re-pulled both revivals’ App Store records and re-checked every LearnClash mechanic against our own backend constants on August 15, 2026, and corrected this page wherever the record disagreed with what we had written.

LearnClash vs QuizUp at a Glance

All three apps share the same core loop: pick a topic, answer questions, compete. Where they part ways is everything around that loop: ranking, review, monetization, and whether the app is still being built at all.

Eight feature dimensions across the three apps. LearnClash fills the space QuizUp left empty.

What Happened to QuizUp?

QuizUp was officially discontinued on March 22, 2021, and its servers went dark two days later. Glu Mobile, which had bought QuizUp in a December 2016 deal valued at $7.5 million, pulled it from the App Store that January. Electronic Arts, which acquired Glu in early 2021, inherited the QUIZUP trademark and then let it lapse: the USPTO cancelled US Registration 4537463 on December 13, 2024 after the ten-year renewal went unfiled. That ending came less than eight years after the fastest launch iOS gaming had seen.

QuizUp’s trajectory: fastest-growing iOS game to permanent shutdown in under eight years.

It started in Reykjavik. Thor Fridriksson, an Icelandic entrepreneur, sketched the idea on the back of an overdue electric bill during a dark Nordic winter. His company, Plain Vanilla Games, was broke. Their first game, a cartoon for toddlers called The Moogies, had flopped. So Fridriksson pitched Lionsgate on a Twilight fan trivia game. TechCrunch’s own timeline sums up what happened next in four words, “And the kids love it,” and in April 2013 the company raised a $2.4 million Series A and built the general-purpose QuizUp we remember.

The growth was staggering. QuizUp launched in November 2013 and hit 1 million users in eight days. Within two weeks, 1.5 million users had signed up and 70 million matches had been played. By May 2014 QuizUp had 20 million users spending an average of 40 minutes per day in the app, rivaling Facebook mobile engagement, and Sequoia Capital and Tencent were among the investors who poured in more than $40 million over the company’s life.

• Nov 2013: Launch, 1M users in 8 days
• May 2014: 20M users, over $26M raised to date, 40 min/day engagement
• May 2015: Social-network pivot, core trivia players pushed aside
• Aug 2016: NBC show canceled, 36 employees laid off
• Dec 2016: Sold to Glu Mobile in a deal valued at $7.5M
• Mar 2021: Servers shut down

But QuizUp never made money. In May 2015 the team pivoted QuizUp into a social network with profiles, messaging, and topic-based discussion forums; core trivia players felt pushed aside. Then NBC signed a 10-episode TV show deal in September 2015, which was supposed to save everything, and canceled the show in August 2016 before it ever aired. All 36 employees were laid off and the Iceland office closed.

Glu ran the app in maintenance mode for a little over four years. The Glu-era App Store listing carried an “Offers In-App Purchases” label, and its reviews read like an exit interview. “Too many ads, no option to buy ad free version?” asked one in February 2018, adding that the frequency of video ads was “outrageous.” By February 2020 another returning player found the app “unrecognizable”: “long buggy ads play constantly,” and “at least 50% of time spent on the app is consumed by ads.”

“We put a lot of our eggs into one basket and then that basket was squashed.” Thor Fridriksson on the NBC bet that was supposed to save QuizUp (PocketGamer, 2020)

Fridriksson has kept trying since. Trivia Royale (June 2020) hit 2.5 million downloads in three weeks and shut down in June 2021 when Teatime Games ran out of money. Rocky Road (a hyperlocal mobile MMO) raised a $3M seed round in September 2023. And in May 2025 the same team shipped its most direct QuizUp successor yet, covered next.

The 2025-2026 QuizUp Revivals: Sway and “QuizUp - The Game”

Two products revived the QuizUp concept, and neither is the original. Sway is the official successor, built by Thor Fridriksson’s Rocky Road Games Inc; Apple lists its release date as May 22, 2025, and its Google Play page was live by July 2025. “QuizUp - The Game” is an unaffiliated iOS app (we found no Google Play listing) published by Two4Tea, a French studio behind Fight List and 94%. It uses a name whose US trademark registration lapsed in Electronic Arts’ hands: the USPTO cancelled it in December 2024, and the only live QUIZUP filing today is a February 2026 application by Youngest Media Group LLC, covering quiz apps and a television game show.

The QuizUp landscape in 2026: one official revival (Sway), one unaffiliated revival (QuizUp - The Game by French studio Two4Tea), and one app that built what QuizUp never had (LearnClash).

	Sway	QuizUp - The Game	LearnClash
Released	May 22, 2025 (App Store); on Google Play by July 2025	July 7, 2025 (App Store; iOS only, no Play listing found)	2025 (active, updated regularly)
Team	Rocky Road Games Inc (original QuizUp creators)	Two4Tea (unaffiliated; also publishes Fight List, 94%)	Pluxia GmbH
Trademark	New brand (“Sway”)	Name matches the lapsed QUIZUP mark (US Reg. 4537463, cancelled Dec 2024; new application by Youngest Media Group, Feb 2026)	Independent brand
US App Store rating	4.8/5 from 3.5K ratings (Aug 2026)	1.0/5 from 2 ratings (Aug 2026)	n/a
Last update	v1.0.35 (Dec 18, 2025): 240 days stale	v1.15.0 (Jul 30, 2026)	Regular releases
Format	Live daily tournaments + 1v1	”Find as many answers as you can” battles with Jokers and Wands (store description)	Async turn-based duels, 72-hour turns; live duels with friends
Ranking	City + topic leaderboards, no ELO	Leaderboards, no rating tiers	8-tier ELO (Iron to Phoenix)
Learning	None	None	3-stage SRS
Monetization	$0.99-$49.99 coin packs + Sway+ ($4.99/week, $15.99/month); coin-gated live shows per Play reviews	$9/week subscription per top reviewer	Premium $7.99/mo or $59.99/yr (7-day trial on the annual plan), zero ads

Sway picks up the real-time thread. Sway Live is a daily tournament where players compete against the world in real time, with creator-hosted game shows and real prizes. Topic breadth covers Taylor Swift, NBA, Harry Potter, Pokémon, Star Wars, Minecraft, world capitals, memes, and hip hop. What Sway rebuilds is the QuizUp energy: crowd, real-time stakes, per-round elimination. What it does not build is ranked skill progression or a review loop. Your wins are counted, not weighted by opponent skill, and nothing you miss comes back to be relearned.

By mid-2026 the App Store complaints had shifted from spelling errors and bot opponents to something more serious. Reviewers in May and June 2026 report that the live shows had stopped, that winnings could no longer be cashed out, and that support did not answer. One May 26, 2026 review puts it flatly: “The live games are completely inactive. Cashing out is no longer possible…” Sway is also Fridriksson’s second trivia restart since QuizUp, after Trivia Royale (2020, dead 2021), and his third company: Rocky Road Games first raised money for a casual open-world game before turning back to trivia.

“QuizUp - The Game” is a different animal. The Two4Tea app uses the exact brand name “QuizUp”, and on the trademark side there is no registered US mark left for Electronic Arts to enforce: the registration it inherited from Glu (Reg. 4537463) was cancelled by the USPTO on December 13, 2024 after nobody filed the ten-year renewal, and the only live QUIZUP filing is a February 8, 2026 application by Youngest Media Group LLC, covering quiz apps and a television game show, still under examination. The game underneath is not the 2013 loop either. Its store description sells “find as many answers as you can” battles with Jokers, Wands, and leaderboards, closer to Two4Tea’s own Fight List than to a topic-pick 1v1, and there are no rating tiers. Its US App Store rating tells the story: 1.0/5 from 2 ratings, checked August 15, 2026, with nothing-like-the-old-game the most cited complaint. Unlike Sway, though, it does still ship updates: v1.15.0 arrived July 30, 2026.

That is the field as of August 2026: one official revival that has stopped shipping, and one unaffiliated revival that ships but scores 1.0. For where the rest of the market sits, see the full list of quiz apps compared.

Sway in August 2026: 240 Days of Silence

Almost fifteen months after its May 2025 release, the Sway story is not a monetization scandal. It is a stall. The iOS build is still v1.0.35 from December 18, 2025: 240 days without an update as of August 15, 2026, on an app whose core pitch is that live shows happen every day. The release notes on that last build still promise “more live shows rolling in.”

To be clear about the money side, since we got it wrong before: Sway has sold coin packs and a Sway+ subscription from its first summer on the App Store. Apple’s July 2025 listing, preserved by the Internet Archive, already showed a $0.99 to $49.99 coin ladder and Sway+ at $3.99 a week or $9.99 a month; by October 2025 the two Sway+ tiers had risen to $4.99 and $15.99, where they still sit in August 2026, and the store describes the subscription as “Unlimited Energy, Extra Live!” The coin economy was already listed by the app’s second month; nothing we can find suggests a free launch that later turned paid.

Metric	Sway, July 2025 (first Wayback capture)	Sway, August 2026
US App Store rating	4.8/5 from 1.3K ratings	4.8/5 from 3.5K ratings
Google Play	Page live by July 17, 2025	4.4/5 from 2.9K reviews, 100K+ downloads
Last iOS build	(not shown in capture)	v1.0.35 (Dec 18, 2025), 240 days stale
Coin packs	$0.99 to $49.99 (four packs)	$0.99 to $49.99, plus a $2.99 300-coin pack and a $1.99 Starting Offer added by October 2025
Sway+ subscription	$3.99/week and $9.99/month	$4.99/week and $15.99/month
Ads	None reported (a June 29, 2025 review: “no ads”)	“Contains ads” on Google Play; round-break ads on iOS since a late-September 2025 update, per an October 6, 2025 review
ELO ranking	None	Still none
Spaced repetition	None	Still none

The ads picture is also plainer than we once reported. Google Play labels the Sway listing “Contains ads,” and an October 6, 2025 App Store review describes an update “a week or so ago” that introduced ads “after EVERY round of Questions. And they are minutes long.” Sway+ is not sold as the cure: its store description reads “Unlimited Energy, Extra Live!”, that same October reviewer asks “why not offer a membership where I can pay to remove the Ads???”, and a December 2, 2025 Play reviewer who bought the $1.99 Starting Offer twice reports that “ads are still shown in between practice trivia rounds.” So: ads on the free tier, and no advertised paid way out of them.

Then there is the live-show economy. We could not verify a specific entry price from store data, but Google Play reviewers report that live shows now cost coins to enter, and it is the 2026 reviews that carry the sharpest complaints: “no more live trivia shows… You can’t cash out,” wrote one June 12, 2026 reviewer, adding that the developers had gone silent. Meanwhile sway.live, the site that listed creator shows, returns a 404 as of August 15, 2026; its last Internet Archive capture is from February 3, 2026.

What lives in the app itself is not fixable without a code release, and there has not been one since December. Sway’s live tournament mode also has no spaced-repetition schedule, so a question you miss never comes back, the same spot QuizUp occupied: fun in the moment, gone by next week.

What Reviewers Say: LearnClash, Sway, and the Clone

A youth-media tester and a QuizUp heir have a natural conversation to have, because the tester’s first question is the one this page keeps asking: what did the app take from the 2010s duel formula, and what did it add? Spieleratgeber-NRW, the state-funded German games-pedagogy body, opens its July 15, 2026 LearnClash review exactly there, with Quizduell’s takeover of 2010s smartphones, and then judges what the AI layer adds. The verdict is mixed and we quote it as such. In the app’s favor: any-topic question generation, the explanation shown after every wrong answer, a spaced-repetition solo mode, and, in a line worth noting on a page about ad-funded rivals, a free version the reviewer records as “werbefrei” (ad-free). Against it: recurring factual errors in the German AI-generated questions, subscription prompts the reviewer found intrusive, and a closing judgment that the app is unsuitable as a classical learning tool because the content stays at trivia depth. The teenagers in the test group advised not to attach too much importance to the quiz. Age recommendation: playable from 12. The German question errors and the premium prompts are both being worked on; the “trivia, not a textbook” verdict is one we accept, because a duel app is what this is.

The Educational App Store reached a friendlier conclusion from a different angle. Its certified review, updated July 15, 2026 and scored 5.0/5 for ages 11 to 18, singles out the retention side: “Many quiz apps stop at revealing the correct answer. LearnClash goes further by providing explanations and follow-up learning opportunities.” Crowd ratings are still a small sample: 5.0/5 from 8 ratings on the US App Store and 8 on the German storefront at the August 15, 2026 check, and no Google Play average yet at 500+ downloads.

Sway has the crowd (4.8/5 from 3.5K ratings on iOS, 4.4/5 from 2.9K reviews on Google Play, August 2026) but, as far as we could find, no editorial review from an education or youth-media outlet. “QuizUp - The Game” has neither: 1.0/5 on the US App Store, and its top review is a one-star complaint about the roughly $9-a-week subscription push.

Topics: Any Topic vs 1,200 Curated Categories

QuizUp’s topic library was its crown jewel: over 1,200 categories covering everything from Harry Potter to advanced chemistry, each with its own fan community. LearnClash takes a different approach. Type any topic and play right away, with questions at easy, medium, and hard difficulty. One is a curated library. The other is a search engine.

LearnClash generates questions on any topic you search. QuizUp’s 1,200-topic library was impressive but finite.

	LearnClash	QuizUp
Topic count	Any topic via search	1,200+ curated
Question source	AI-generated, validated	User-submitted
Difficulty levels	Easy, medium, hard (ELO-calibrated)	Single difficulty
Fresh content	Infinite, always new	Fixed pool, repeats
Quality control	Automated validation pipeline	Community moderation

QuizUp’s user-submitted questions had a charm to them. Fans wrote questions about their favorite shows and games with insider knowledge only true fans would have. But quality varied wildly: some topics had hundreds of well-crafted questions while others had a dozen poorly worded ones that repeated every few matches.

LearnClash generates questions on demand for any topic you type. Byzantine military tactics, 1990s one-hit wonders, Albanian folklore, the hash functions behind Bitcoin mining. None of it existed in QuizUp’s 1,200, and most of it is not in Sway either. The trade-off is real, though: LearnClash has nothing like QuizUp’s per-topic fan communities, and anyone who valued those more than the questions themselves will feel the gap.

Competition: ELO Ranking vs Topic Leaderboards

QuizUp tracked wins on per-topic leaderboards, and those leaderboards had a flaw anyone who chased a #1 spot in 2014 will remember: they rewarded volume over skill. Play 500 games on a topic and you would rank high regardless of win rate. You could be #1 in Harry Potter and #847 in Geography, and neither number said how good you were, because a win over a first-week novice counted exactly as much as a win over the topic’s best player. Neither revival fixed this. Sway uses city leaderboards and per-topic ranks, and the unaffiliated “QuizUp - The Game” has leaderboards but no rating tiers.

The fix is old and comes from chess: rate the player, not the win count. LearnClash uses an ELO-style rating across 8 tiers from Iron to Phoenix, 22 ranks in total, where beating stronger opponents earns more rating points.

LearnClash tracks skill across 8 ranked tiers. QuizUp counted wins on flat leaderboards.

	LearnClash	QuizUp
Ranking type	ELO rating (global) + per-topic mastery leaderboards	Per-topic win/loss leaderboards
Tiers	8 major tiers, 22 ranks (each splits into III/II/I except Phoenix)	None
Skill tracking	Glicko-2 engine shown as an ELO-style number	Simple win count
Cross-topic skill	Yes (global ELO)	No
Progression feeling	Climb tiers, see rating change each duel	See position on leaderboard

While re-verifying this page on August 15, 2026, I re-opened the rating constants file in our backend to make sure this section still matches the shipped code. It does: eight tiers from Iron (the rating floor is 100) to Phoenix (2400 and up), 22 ranks, and the comment at the top of the file reads “Starting rating (1300) = Gold II (average)”. That start point is deliberate: a new account lands in the middle of the ladder, not at the bottom, so its first duels are calibration rather than a climb out of Iron. One correction from the same check: the per-topic boards in LearnClash are mastery leaderboards, ranked by a topic mastery score, not per-topic ELO ratings. An earlier version of the table above said otherwise.

Underneath that rating sits Glicko-2, the same math chess sites run, surfaced in the app as a single ELO-style figure. A brand-new account carries a wide rating deviation, which is why its first duels swing hard; after roughly ten of them the swings die down, and from there an evenly matched win or loss moves you about 20 points. LearnClash pairs you with opponents close to your ELO, which keeps duels competitive instead of lopsided; see how the ELO-matched matchmaking math actually works for the algorithm breakdown, and how the ELO rating system works for the rating math itself.

Learning: Spaced Repetition vs Play-and-Forget

Miss a question about the Treaty of Westphalia in a QuizUp duel and it was gone for good: nothing tracked what you knew, nothing scheduled review. You answered, saw the result, moved on. That is the opposite of what memory research says a quiz should do. The testing effect is one of the most replicated findings in the field: pulling a fact from memory makes it stick far better than rereading it, and the gain grows when the retrievals are spaced out over days and weeks instead of crammed into one sitting. Sway and “QuizUp - The Game” inherit QuizUp’s gap: neither tracks retention.

LearnClash SRS keeps retention high over weeks and months. QuizUp (and its revivals) have no retention system.

	LearnClash	QuizUp	Sway
Spaced repetition	3-stage SRS in every mode	None	None
Practice mode	6-question solo sessions	None	None documented
Mastery tracking	3 stages (Learning → Known → Mastered)	None	None
Knowledge retention	Compounds over weeks and months	Resets every game	Resets every tournament
AI tutor	Clash (chat about any question/topic)	None	None

LearnClash builds that 3-stage cycle into every game mode, so a missed question re-enters the pool and comes back at timed intervals until you own it. For the full science, read how spaced repetition actually works and how to study effectively using retrieval practice.

Solo mode gives you 6 focused questions per session on any topic. It is pure SRS: due reviews get served first. Free players get one solo session per rolling 24 hours; Premium raises that to 20 sessions an hour. Read more about the testing effect and how retrieval practice works or the broader case for competitive learning.

Multiplayer: Turn-Based vs Real-Time

If you played QuizUp in 2014, the thing you remember is racing a stranger in real time: same questions, same countdown clock, both of you tapping at once, often from opposite sides of the planet. Sway revived that loop in 2025, including a daily live-tournament layer with creator hosts, and its early reviews say the feeling came back with it. Real-time has costs, though. You need both players online at once. Finding an opponent can mean waiting (Sway’s own reviewers complained about bot fill-ins), disconnects kill matches, and because questions are live, speed often matters more than knowledge: players who memorize the question pool can tap answers before reading the full text.

LearnClash: play on your schedule across 6 topics. QuizUp (and Sway): both players race at once.

	LearnClash	QuizUp	Sway
Format	Turn-based (async); optional live duels with friends	Real-time (at once)	Real-time (tournaments)
Time per turn	72-hour window	Instant (both play live)	Tournament-paced
Players per match	2 (1v1)	2 (1v1)	Up to hundreds per tournament
Questions per duel	18 (6 topics, 3 each)	7 (1 topic)	Variable per round
Topic selection	Player picks; algorithm ensures 6 diverse topics	Player picks 1 topic	Host picks tournament theme

LearnClash took the opposite road: async turn-based duels with a 72-hour window per turn. You play when it suits you, morning commute, lunch break, before bed, and your opponent plays on their schedule. The window gives everyone time to think, and because duels span six topics with three questions each, winning takes range, not just one specialty. If you loved QuizUp’s instant matches and just want that feeling back, Sway is the closer match, with the caveat that its 2026 reviews report the live shows have gone quiet. If you want your wins weighted by opponent strength and your misses to come back, the slower pace is the point.

Update, August 2026: LearnClash now closes the one gap this section conceded. Start a duel from a friend invite or a live challenge link while you are both online, and the same LearnClash duel plays live, question for question, in lockstep.

The difference from QuizUp’s model: speed still earns nothing. Your answer window is yours alone, nobody scores your milliseconds, and if one of you stays away past a short grace window, the duel quietly continues as the normal 72-hour turn-based game. Live plays with friends only (there is no stranger matchmaking for live), and async stays the default.

Pricing and Ads: The Lesson QuizUp Taught Everyone

QuizUp launched with no ads and no revenue model at all. The monetization came under Glu, and the App Store reviews from that era describe how it landed. “Too many ads, no option to buy ad free version?” (February 2018). “Long buggy ads play constantly,” and “at least 50% of time spent on the app is consumed by ads” (February 2020). Sway went a different way from day one, a coin economy listed since its first summer, then added round-break ads with a late-September 2025 update. LearnClash took a third route: a subscription for more features, zero ads for everyone, and no coin packs or pay-to-win purchases.

LearnClash charges for more features, not fewer interruptions. QuizUp’s ad-based monetization drove users away. Sway’s coin ladder has been listed since July 2025.

	LearnClash	QuizUp (Glu era, 2017-2021)	Sway (August 2026)
Ads (free tier)	Zero	Yes; video ads at a frequency a Feb 2018 review called “outrageous”	Yes (“Contains ads” on Google Play; an Oct 2025 review describes minutes-long ads after every round)
Ads (paid tier)	Zero	No ad-free option (“no option to buy ad free version?”, Feb 2018 review)	Sway+ is sold as “Unlimited Energy, Extra Live!”; no ad-removal purchase listed
Subscription	$7.99/mo or $59.99/yr (7-day free trial on annual, in-app)	None seen (ads + IAPs)	Sway+ $4.99/week or $15.99/month
In-app purchases	Subscription only, no coin packs or consumables	Yes (“Offers In-App Purchases” label; items from $0.99 in a May 2020 store capture)	$0.99 to $49.99 coin packs (listed since July 2025)
Tournament entry	n/a (no tournament layer)	n/a	Coin-gated live shows, per Google Play reviews
Free tier includes	Daily duels, all topics, ELO, daily SRS	Base game with ads	Casual play; live shows coin-gated per reviews
Pay-to-win	No	Paid extras (“you can choose to pay real money for some extra items”, Glu-era listing)	Coin economy since launch

Here is how the two monetization designs actually differ. Sway monetizes with a coin economy: $0.99 buys 100 coins and $49.99 buys 7,000, alongside a Sway+ subscription at $4.99 a week or $15.99 a month, and Google Play reviewers report that entering live shows costs coins. LearnClash monetizes progression instead: a 22-rank Glicko-2 ladder from Iron to Phoenix and a 3-stage spaced-repetition cycle that re-checks misses after 7 days and knowns after 90, with zero ads and no coin packs on any tier.

QuizUp’s users were not cheap. They loved the app and played 40 minutes a day. But when Glu tried to monetize that engagement through ads and paid extras, the uninterrupted quiz experience that made users loyal was the first thing to go, and in early 2018 at least there was not even a paid exit: the reviewer who asked for an ad-free version that February says they “would in a heartbeat” have paid for one. Two years later a returning player called the app “unrecognizable.” The same paywall escalation keeps showing up across the category, from Kahoot 360 Spirit at $20/month to the Quizlet Plus arc covered in our Kahoot vs Quizlet comparison; the unaffiliated “QuizUp - The Game” charges a $9 weekly subscription per its top reviewer.

LearnClash’s answer to Glu’s escalation is zero ads on any tier: not on the free plan, not behind a paywall, no coin packs, no paid tournament entry. Spieleratgeber-NRW’s tester, no fan of our subscription prompts, still recorded the free version as “werbefrei.”

The free tier includes daily duels, all topics, the full 8-tier ELO ladder, and one daily solo session. Premium ($7.99/month or $59.99/year; new subscribers on iOS and Android get a 7-day free trial on the annual plan in the app) adds near-unlimited solo practice (up to 20 sessions an hour), advanced stats, and exclusive cosmetic rewards, and raises the streak freezes you can hold from 1 to 3.

What QuizUp Never Built: ELO + Spaced Repetition

Here is the opinionated take, and it shaped how we built LearnClash: QuizUp died because it had no retention engine. 100 million downloads, and nothing to bring a player back once they had mastered their favorite topic. Sway is rebuilding the live show that pulled people in. What neither QuizUp nor its heirs built is the part that keeps them: skill-ranked matchmaking plus spaced repetition.

The engine QuizUp never built: no way to say “here is a harder opponent” or “here is your 7-day review.”

What the retention engine needs	QuizUp	Sway	LearnClash
Skill-weighted matchmaking	Per-topic win counts	Per-city + topic leaderboards	8-tier ELO-style ladder on a Glicko-2 engine
Forgetting-curve review loop	None	None	3-stage SRS (7d, 90d checks)
Re-engagement trigger	Push notifications only	Daily tournament hook	SRS review + quest streaks
Progression ceiling	None (hit #1 once, done)	Tournament leaderboard refresh	ELO tier climb + mastery pool
Learning compounding	Zero	Zero	Retention stacks over months

Think about what QuizUp’s 40-minute daily sessions actually produced. A player mastered their topic in month one, hit the top of their per-topic leaderboard, and then what? The app had no way to say “here is a harder opponent” or “here is the 7-day review from your weak spots.”

LearnClash’s answer has two parts. ELO makes every duel matter: beating a higher-rated opponent moves your number more than beating a lower-rated one, and a Phoenix-tier player cannot grind easy wins because Glicko-2 pays almost nothing for beating far weaker opponents. SRS makes every question matter: yesterday’s misses come back in 7 days and pass to the 90-day check on success, visible in your weekly stats. Sway might build this eventually; as of August 2026 neither revival has.

Who Should Pick LearnClash as Their QuizUp Alternative

The seven-point match profile for LearnClash.

Download LearnClash if:

• You miss QuizUp’s topic-based duels and want that format back
• You want a ranking system that tracks real skill, not just win counts
• You care about retaining knowledge, not just having fun for five minutes
• You want zero ads without paying to remove them
• You liked QuizUp’s breadth but want better question quality and infinite topics
• You want an app that is actively developed, not abandoned in maintenance mode
• You want to play on your schedule with 72-hour turns

Who Might Prefer Sway or the QuizUp Revival Instead

The short-list profile for Sway over LearnClash. Different job, different app.

Be honest: Sway delivers some things LearnClash does not. We skipped them on purpose.

• You miss real-time simultaneous play against strangers with a crowd racing through questions at the same moment. Sway Live rebuilt exactly that feeling, though reviewers in May and June 2026 report the shows have gone quiet.
• You want tournament pageantry with a live host and real prizes. Sway’s daily tournaments are the direct descendant of QuizUp’s old topic leaderboards. LearnClash has no tournament layer.
• You valued topic-specific fan communities and hand-curated questions written by enthusiasts. Sway’s curated library and city-based social ties are closer to that than LearnClash’s any-topic AI approach.
• You want the QuizUp brand nostalgia, literally. “QuizUp - The Game” keeps the name on the icon, if that matters more than the features underneath.

So the split is by job. Live hosted trivia with a crowd, coin economy included, on an app whose last iOS build dates from December 2025: that is Sway. The name on the icon and nothing else: “QuizUp - The Game”. Wins ranked on a 22-rank ELO ladder and misses re-taught on a 7-and-90-day schedule, with no ads at any tier: LearnClash.

The original QuizUp is not coming back. Its servers went dark in March 2021, its US trademark registration lapsed in December 2024, and the only live QUIZUP filing is a February 2026 application tied to a television game show. But the demand QuizUp proved, 100 million downloads of topic-based quiz duels, is clearly still real.

Where That Leaves You

QuizUp proved that 100 million people want to compete on topics they care about, and then could not give them a reason to come back once a topic was mastered. Sway rebuilt the live-tournament format for that audience in 2025 and has since gone quiet, with no iOS update in 240 days and 2026 reviews reporting stalled shows and blocked cash-outs. “QuizUp - The Game” borrowed the name and ships at 1.0/5. Neither solves the retention problem, which is the one LearnClash was built around.

The short-version pick. LearnClash for skill + memory and zero ads. Sway for live nostalgia, coin economy included.

LearnClash answers that with ELO ranking, the 3-stage SRS engine we threw out the 1/3/7/21 schedule for, any-topic AI, and a zero-ads, zero-coin-pack model. Each round takes three minutes.
