High schools run on information, yet students must track announcements, clubs, schedules, and events across disconnected channels, missing the participation and belonging that improve academic outcomes, while the general social platforms they fall back on expose them to unsafe content. This paper presents Quilt, a single mobile application that unifies a school's communication, organization, and community into one school-scoped and moderated space. Built with Flutter and Google's Firebase platform, Quilt ties membership to a verified school identity, lets clubs post and poll, shares a common bell schedule and event calendar, connects parents to their students through a consent-based QR link, and keeps the feed safe by pairing an on-device content-safety filter with a human reporting-and-moderation workflow. Key challenges around moderation accuracy, real-time synchronization at school scale, and the privacy of a parent-student link were addressed through a layered filter-and-report design, a real-time database with local caching, and an in-person QR exchange. By consolidating scattered channels and treating safety as a first-class concern, Quilt targets the informational, social, and safety gaps that make school life harder than it needs to be.
