LearnClash is a competitive learning app where curious minds master any subject through 1v1 quiz duels. Pick any topic, from Quantum Physics to Pop Culture, and duel opponents matched to your skill level. Each player earns an ELO rating across 8 ranked tiers from Iron to Phoenix. Built-in spaced repetition means the questions you miss come back until you master them. Free on iOS, Android, and web.
What to expect from an ideal product
- LearnClash brings back questions you got wrong automatically, so you keep seeing tough concepts until they stick in your memory
- The competitive 1v1 format makes you actively recall information under pressure, which helps your brain remember facts much better than passive studying
- Your missed questions return at smart intervals - first after a day, then a week, then longer gaps as you prove you know the material
- The ELO ranking system across 8 tiers keeps you motivated to practice regularly, which is key for spaced repetition to work properly
- Each quiz duel forces you to retrieve knowledge quickly, and the app tracks what you struggle with to repeat those exact topics later
