§The problem
People nearby could share bulk purchases and split the cost, but finding others in the same area who want the same thing takes effort. i-Share puts those co-buyers in one place: a C2C platform for sharing retail products within a local community.

§What it does
Nearby co-buyers — GPS-based geolocation matching connects people close to each other, so finding interested participants takes less effort.
A map of requests — the Google Maps API shows co-buying requests on an interactive map, by proximity.
Real-time data — Firebase Firestore keeps everyone in sync; Firebase Authentication manages users securely.
Trust between strangers — group chat, QR-code attendance verification at hand-over, and a credibility scoring system.
