Crumb

Jenna Stein

Crumb is a hyperlocal food-sharing app that helps apartment residents cut down on food waste effortlessly. Users can post surplus or near-expiry food, share it with neighbours, or schedule weekly SA Harvest pickups for unclaimed items. Built with a human-centered design approach, Crumb simplifies sustainable habits through reminders, freshness filters, and community engagement, turning small, everyday actions into collective impact and lasting behaviour change.
