LearnClash: 1v1 Quiz Duels

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. Play during a coffee break, on your commute, or between meetings. You pick a topic, then your opponent picks theirs. Duels are turn-based with up to 48 hours per turn, so they fit around your life.

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. Beat stronger opponents to rise faster. Fair matchmaking keeps every duel competitive.

CLASH CHAT: YOUR AI TUTOR

Got a question wrong? Ask Clash Chat why. Get instant, detailed explanations that turn mistakes into learning moments. Dive deeper into any topic and understand the "why" behind every answer.

PRACTICE MODE

Not ready to put your Elo on the line? Practice solo on any topic with 9-question sessions. Build confidence and knowledge before you compete.

CHALLENGE ANYONE, ANY LANGUAGE

Send a challenge link to anyone. Each player sees questions in their own language. Same duel, fair competition, no barriers. Duels work across English, German, French, and Spanish.

DAILY QUESTS AND STREAKS

Three daily quests keep you learning consistently. Earn Mems, build streaks for bonus rewards, and develop a daily learning habit.
