Overview

Replen makes grocery shopping simpler for Canadians, with a React Native app that covers the whole journey from filling a basket to tracking the delivery. We designed and built it for both iOS and Android from a single codebase, backed by a Node.js and MongoDB stack that keeps the experience fast and user data secure. The focus throughout was on the everyday details that make online grocery shopping feel quick and reliable.

The challenge

Making the weekly shop quick

Online grocery shopping lives or dies on the small things: how quickly you can reorder a favourite, whether your address is right, and knowing where your delivery is. Replen needed to handle all of that smoothly across two platforms, tailored to the Canadian market, while keeping user information secure and the interface clean and friendly enough to come back to week after week.

Our approach

Research first, then build

We began with market research to understand the specific needs of Canadian grocery shoppers, then built on React Native's component-based architecture for true cross-platform reach. We prioritised the features that matter most to a weekly shop, including address input, cart management, favouriting and order tracking, and refined them through iterative development cycles. A Node.js backend with MongoDB keeps the app scalable and handles user data securely.
