FactCheckr
FactCheckr is a mobile + web trivia app built around verifiable questions. Every question includes a citation link (article, book excerpt, dataset, or official site) and a short “why this is true” explanation revealed after answering. Players can challenge friends or join public rooms, but the core hook is trust: you can flag dubious questions, and high-reputation editors (plus automated checks) keep the database clean. It’s not for people who want pure party chaos; it’s for players tired of wrong answers, outdated facts, and recycled trivia packs. Monetization is realistic: a free tier with ads and limited modes, plus a subscription for ad-free play, premium packs, and private leagues. The hard part is content quality and moderation, so the MVP should start narrow (e.g., science, history, pop culture) and expand only when accuracy workflows are solid.
