Overview

Stamply is a digital loyalty app for Android that rewards users for shopping at small businesses locally. Built for the Adobe Creative Jam × Instagram competition, it won 1st place — praised for simplicity, community focus, and support for minority-owned businesses.

I partnered with another student designer to create the full experience — from research through high-fidelity prototype — with a explicit constraint: accessibility for users in low-bandwidth environments.


The problem

Customers juggle multiple loyalty programs across apps, leading to confusion and missed rewards. Small businesses — especially those without robust digital infrastructure — struggle to compete with chain loyalty programs.

How might we help people discover and support local businesses through a loyalty experience that works even on slow connections?


Process

We designed for users in low-bandwidth areas, which forced tradeoffs between simplicity and feature richness. Design thinking, user flows, and progressive fidelity — from text-only wireframes to a full Material Design system — kept the experience usable on slow connections.

  • Result: 1st place
  • Competition: Adobe × IG
  • Constraint: Low bandwidth

Design thinking

We brainstormed user scenarios and applied design thinking to real-world access constraints — particularly for customers who couldn't rely on media-heavy interfaces.

User flow

I created a user flow map to streamline discovering small businesses nearby — emphasizing a rewarding, low-friction path from search to stamp collection.

Looking ahead

If I revisited Stamply today, I'd refine the visual system for stronger community feel, integrate customer reviews, and explore a business-facing version with tailored profiles for shop owners.
