What it does
LearnClash is a quiz duel app where you play a one-on-one match on general knowledge or a topic you pick. Each turn is six questions at 45 seconds apiece, and your opponent has 72 hours to play theirs. You can challenge a friend with a link, get matched with another player, or play one of six clearly labelled AI rivals. After every answer you can read why it is right, and you can ask Clash, the AI tutor, follow-up questions. Missed questions come back after 7 days, and again after 90 days once answered correctly, which works as spaced repetition. If a topic does not exist yet you can create it, and the AI writes and checks questions for it on demand. The site says it is free to play with no ads in any tier, offers a daily quiz in the browser, and has iOS and Android apps. It is built by Pluxia GmbH in Baar, Switzerland.
