Local used-goods trading,
in one hand

A used-goods mobile app built around the user's location. Location-based product recommendations, live chat and trust scoring all live inside the app — the essentials of a safe trade in one place.

01 — CHALLENGE

Local trading is about meeting people who are near you — but rendering 'near' inside an app is harder than it sounds.

Imprecise location filtering wastes user time on listings that are too far. Tight filtering shrinks inventory too aggressively to support real trades. Trust information sat apart from listings, leaving doubt right before a deal.

For the operator, reports, payments and disputes lacked a single console to handle them.

02 — APPROACH

Location-based recommendations sit at the center, live chat and trust scoring share one screen, and operators handle the same data through an admin built around their work.

Location-based recommendations come first. From the listing page, a tap drops straight into chat. Trust score combines transaction count, reviews and report history into one number.

An admin dashboard handles reports, payments and listings on one screen, lowering operator workload.
