Civic mobile app

Community-fridge locations on a map, editable by users

Community Fridges is a mobile utility: map-based discovery, adding and editing locations, reports, alerts, and a Supabase backend for fast iteration.

Map-first discovery

OpenStreetMap helps users quickly find nearby community fridges.

Community updates

Users can submit new places and correct existing data.

Serverless backend

Supabase supports auth, database, and quick operational changes.

The challenge

Make community-fridge locations easy to find and keep up to date

The project was a mobile tool, not a simple informational website. It had to show fridge locations on a map, allow users to submit and correct places, support reports, and keep the data useful during periods of increased food waste.

Display community-fridge locations in a clear mobile map.
Let users add, edit, and report locations.
Use a lightweight backend that supports fast iteration.
