FamilyCart
A collaborative grocery list app with real-time sync and zero-friction onboarding, built for families.
Overview
FamilyCart is a collaborative grocery shopping app designed to make family shopping seamless. The app enables multiple family members to contribute to and check off items from a shared list in real-time, eliminating the chaos of uncoordinated grocery runs.
The Challenge
Families struggled with coordinating grocery shopping—duplicate purchases, forgotten items, and the inability to collaborate in real-time were common pain points. Existing solutions were either too complex or required everyone to create accounts, creating friction for adoption.
The Solution
I architected a serverless multi-tenant solution using Firebase that enables instant collaboration without requiring account creation. The app features zero-friction onboarding where users can start a shared list and invite family members within seconds. Built with React Native and Expo for cross-platform support, with offline capability ensuring the app works even in stores with poor connectivity.
Results & Impact
- Successfully shipped to the App Store
- Zero-friction onboarding with instant family sharing
- Real-time sync across all family members' devices
- Full offline capability for in-store use
