Spendly is a shared shopping list app for real households.
I am planning a mobile app for families, partners, flatmates, and small groups who need a simple way to coordinate shopping. The idea is to combine shared lists with the feeling of private circles, so people can tick off what has been bought as they go.
Early concept. This page will become the public build log, product notes, and eventual case study for the app.
What Spendly Should Do
The first version should stay small: shared circles, shared lists, and a smooth way to mark progress while shopping.
Families, partners, flatmates, or friend groups can create private circles and keep shopping responsibilities in one place.
Items can be added, assigned, and ticked off as people shop, reducing duplicate purchases and forgotten essentials.
Inspired by the usefulness of Life360-style circles, Spendly can eventually help groups coordinate who is near a shop.
Future versions could track rough spend, split costs, or show who bought what without turning the app into a full finance tool.
From idea to case study.
The goal is not just to build another todo list. The goal is to show product thinking, mobile UX decisions, real-time state, and a clear technical write-up.
Define the core user flows for creating a circle, inviting people, and adding list items.
Design the first mobile screens for circle overview, shared list, item detail, and completed items.
Build a small MVP with authentication, circle membership, and real-time list updates.
Test with a small group and write a case study covering product decisions and technical tradeoffs.
Portfolio angle
Spendly can become a strong portfolio project because it has a real audience, clear collaboration problems, mobile-first UX, and enough technical depth for authentication, permissions, real-time data, and deployment decisions.
