Trivia Duel
Vim Python IDE
LearnClash is a competitive quiz duel app where players challenge friends on any topic. Unlike fixed-category trivia apps, it generates questions on any subject at every difficulty level.
Pick any topic: science, Harry Potter, history, or thousands more. Each duel has 18 questions across 6 rounds. Challenge friends or get matched by skill via ELO.
8 tiers from Iron to Phoenix. Start at 1300 ELO (Gold II). Every answer feeds into spaced repetition across duels, Solo, and daily challenges. Wrong answers return at optimized intervals.
Trivia Crack: fixed categories. Kahoot: needs a host. QuizUp: shut down. LearnClash combines any-topic questions, 1v1 duels, and learning science.

LearnClash's answer
LearnClash is the only quiz app that combines three things no competitor offers together: questions on any topic at every difficulty level, a chess-style ELO rating system with 8 competitive tiers, and spaced repetition built into every game mode. You don't just play trivia, you actually learn and retain knowledge.
LearnClash's answer
Trivia Crack limits you to 6 fixed categories. Kahoot requires a host and is designed for classrooms. QuizUp shut down. LearnClash lets you pick any topic, matches you with opponents at your skill level through ELO, and uses spaced repetition so you remember what you learn. It's competitive trivia that makes you smarter.
LearnClash's answer
Anyone who loves trivia and wants real competition. Students who want to learn while having fun, friend groups who want to challenge each other on specific topics, and trivia enthusiasts who've outgrown Trivia Crack's fixed categories. Ages 16-45, primarily in the US, with growing communities in Germany, France, and Spain.
LearnClash's answer
LearnClash was built by David Moosmann to solve a personal frustration: existing quiz apps felt random and didn't help you actually learn. By combining AI-generated questions on any topic, ELO matchmaking from competitive gaming, and spaced repetition from learning science, LearnClash turns casual trivia into genuine knowledge building.
LearnClash's answer
Flutter for cross-platform iOS and Android, Firebase for backend infrastructure (Firestore, Cloud Functions, Auth, FCM), Gemini AI for question generation and validation, and RevenueCat for subscription management. The ELO system and spaced repetition engine are custom-built.
LearnClash's answer
Thank you for considering LearnClash.
I built this app to replace the ad heave quiz duel apps that I was playing with my mum. I wanted to build a way better version with proper ELO ranking and SRS system. Enjoy!
