About this project

Overview

A household management app for couples. Shared task lists with real-time sync via Supabase Realtime, grocery lists with voice input and smart parsing, a shared recipe book with a public library, household notes, and a budget tracker — all synced live between two phones.

The core technical bet was Next.js 14 App Router with Supabase for everything backend: auth, PostgreSQL, real-time subscriptions, and row-level security. I chose this stack because it lets one developer ship a full product fast without managing servers.

The honest reason I built it: I wanted a couple app that wasn't trying to be a startup, had no ads, and did exactly what we needed. We use it every day.
