Losing something in Johnstown means juggling calls to the police, checks with local transit, posts in scattered Facebook groups, and hope. Shelters hold items for only a few days, online marketplaces fill up fast, and there's no single place where all lost items surface. The moment something goes missing, the clock starts, but also a feeling of helplessness: where do you even start?

ReportLost simplifies that chaos. One clear report captures your loss and reaches the Johnstown Police Department, Core Transit, the Northern Colorado Humane Society (if it's a pet), and the community groups that locals actually monitor. Better still, your report doesn't stop searching after a day or a week. It stays active for up to a year, automatically cross-referencing new found posts and announcements, so you can focus on your day while your search keeps working behind the scenes.
