Project Overview

A mobile location picker redesign for a marketplace app where users list items tied to geography. The existing flow caused friction: unclear map boundaries, imprecise pin placement, and weak feedback when a location was out of service area.

My Role

UX designer and iOS/Android prototype owner — from field research and usability testing through handoff to engineering with motion specs and edge-case documentation.

Technologies & Tools

  • React Native
  • Mapbox SDK
  • Figma & Principle (motion)
  • Amplitude (analytics)
  • Swift / Kotlin (native map bridges)

Process

I shadowed sellers during listing creation and mapped pain points on a journey diagram. We introduced progressive disclosure: search first, map refinement second. Haptic and visual confirmation reinforced successful pin drops. Geofencing rules were surfaced inline instead of after submission. Iterative usability tests (n=12) validated the simplified two-step model.

Outcomes

  • Listing completion rate for location step up ~22%
  • Support tickets about "wrong location" down ~35%
  • Median time-on-step reduced by 40 seconds
  • Shipped as the default picker across iOS and Android
