The Problem

What needed solving

Shared shopping lists are badly served. A notes app only one person can see doesn't cut it, and the polished alternatives tend to ask for a subscription before they'll let two people share a single list. The most ordinary case - a household keeping one list that's always current - was the one nobody solved simply.

The Build

What I delivered

A React Native app built with Expo. Every account gets a six-character sync code; enter someone else's code and you're both on the same list from then on - no invites, no email addresses, no accounts to link. Items sync through live database listeners, so ticking something off updates every phone at once. Each item carries a category and the shop you'll buy it at, so the list organises itself into a sensible order by the time you're in the aisle. It ships through the Play Store with over-the-air updates, so fixes reach users without waiting on a store review.
