What is LearnClash?

LearnClash is a quiz-based learning app that uses competitive 1v1 duels to make studying more engaging. Players answer questions on any topic, compete against others in real time, and earn ELO rankings based on their performance. The app employs spaced repetition, a learning technique that spaces out review of material over time to improve long-term retention. It's designed for people who want to study in short bursts; the app suggests learning sessions take around 3 minutes daily. There are no ads and no paid tier, making it accessible to anyone with a smartphone. The competitive element and ranking system appeal to learners who respond well to gamification.
