Groz App

Overview

Grozapp is a hyperlocal delivery platform connecting customers with local stores for groceries, food, medicine, pet supplies, and daily essentials. I was responsible for designing the entire product ecosystem — all three apps: Customer, Delivery Partner, and Store Owner — creating a unified experience across every side of the delivery chain. Most delivery apps are designed from one perspective — the customer. Grozapp required thinking across three completely different user contexts simultaneously, while keeping all three apps feeling like one coherent product.

Three users, three mental models, one product

A delivery platform has three distinct users, each with completely different needs, contexts, and stress levels. A customer wants speed, variety, and trust. A delivery partner is on the move, often under time pressure, needing clarity with zero distraction. A store owner needs inventory control and order management without complexity. The core design challenge: how do you build three apps that serve completely different mental models, while still feeling like one coherent product? The challenge wasn't designing three good apps — it was making sure all three worked together as one system.

From ecosystem map to design system

Before designing any screen, I mapped the complete order lifecycle and built the shared design system that would hold all three apps together.

Ecosystem mapping — the complete order lifecycle from placement to delivery, identifying every touchpoint where each user type intersects and where friction could occur if the apps weren't designed in sync
Competitive research — analysed Blinkit, Swiggy Instamart, and Zepto, not just for UI patterns but for where they failed each user type; delivery partner apps were consistently underdesigned
User personas — an urban customer ordering during lunch, a gig-economy delivery partner managing 6–8 orders daily, and a small store manager who isn't highly tech-savvy
Shared design system — a component library with unified typography, colour tokens, icon set, and button styles across all three apps, built before touching individual screens
Flow-by-flow wireframing — Customer: discovery → cart → checkout → tracking. Delivery: order queue → navigation → confirmation. Store: inventory → orders → sales summary
Loyalty & retention design — the loyalty points system and Groz App Wallet, designed to make earning and redeeming feel visually rewarding and frictionless
