LearnClash

LearnClash is the competitive learning app for curious minds. Pick any topic, get matched against an opponent at your ELO tier, and play an 18-question duel across six rotating topics. Three stages of spaced repetition (Learning, Known, Mastered) move every answer through 7-day and 90-day re-checks until the knowledge sticks. Eight ELO tiers from Iron to Phoenix, async 48-hour turns, and zero ads in any tier.
