How much do you really know? Prove what you know. Learn what you don't. Quiz duels against real people, every answer explained, and missed questions come back.
3 minutes a day. Learn any topic through ranked 1v1 quiz duels with built-in spaced repetition and Elo ranking from Iron to Phoenix.
Master any topic. That is the idea behind LearnClash, a competitive learning app where you challenge friends to 1v1 quiz duels and retain what you learn through built-in spaced repetition.
LEARN ANY TOPIC
Quantum physics? 90s hip-hop? Your favorite TV show? Just type it. LearnClash generates fresh questions on any subject. No preset categories. If you can think it, you can learn it.
HOW IT WORKS
Pick any topic and challenge a friend via a link. Each duel has 6 rounds with 3 questions per round (18 questions total), 45 seconds per question. Every duel deals both players the same fair hand of topics to pick from. Duels are turn-based with up to 72 hours per turn, so they fit around your life. Both online? Invite your opponent to play live, question for question. Live starts when they accept.
DAILY CLASH
One six-question challenge a day. One theme, everyone plays the same set. Finish it, share your result grid with friends, and build your Clash streak.
SPACED REPETITION BUILT IN
LearnClash tracks every question you encounter across three mastery stages: Learning, Known, and Mastered. Questions you struggle with come back at the right intervals. Over time, you build deep, lasting knowledge on the topics you care about.
ELO RANKING SYSTEM
Your skill is measured with the same rating system used in chess. Start at 1300 Elo (Gold II) and climb through 8 tiers: Iron, Bronze, Silver, Gold, Platinum, Emerald, Diamond, and Phoenix. Fair matchmaking keeps every duel competitive.
THE RIVAL LADDER
Six AI rivals, from Pip to Zenith, each clearly labeled as AI. Challenge one on any topic: a rival always answers, no waiting. Beat each to unlock the next. Rival duels never touch your Elo.
CLASH CHAT: YOUR AI TUTOR
Got a question wrong? Ask Clash Chat why. Get instant, detailed explanations that turn mistakes into learning moments. Understand the "why" behind every answer.
SOLO MODE
Not ready to put your Elo on the line? Train in Solo mode on any topic with quick 6-question sessions. Build confidence and knowledge before you compete.
CHALLENGE ANYONE, ANY LANGUAGE
Send a challenge link to anyone. They can play the first round of 3 questions in the browser. Each player sees questions in their own language. Same duel, fair competition, no barriers. Duels work across English, German, French, and Spanish. Shared links start turn-based duels. Live play needs a separate accepted invitation.
QUESTS, STREAKS, AND FRIENDS
Three daily quests keep you learning consistently. Earn Mems and build streaks for bonus rewards. Build pair streaks with a friend and repair one when life happens.

Thank you, Mario. Fun is the whole idea: every question you miss comes back later until it sticks, so the game does the studying for you. David (LearnClash)

Developer Response
Thanks for trying LearnClash. Fair point that the look feels familiar. The game itself works differently: you duel another player on the same questions, and after every answer you get a short explanation, so even a lost duel teaches you something. If something specific felt off, tell us at admin@learnclash.com. David (LearnClash)
Start your first duel with fewer setup steps. Question cards, progress stats and the screen for adding your learning materials have a new look. We also improved navigation when you cancel a live invitation. Fixed an issue that could stop more topics from loading as you scroll.
