Your neighbourhood budgeting app - Swift. Short. Simple.

Living with flatmates is all fun and games - until the bills show up. Money quickly becomes the awkward elephant in the room.


Everyone has their own budget style (and income), but keeping track without stepping on each other’s toes? Not so easy.

Create a budgeting app that makes personal finance simple, keeps shared expenses fair and transparent, and turns household money management into a fun, accountable experience.

Create a budgeting app that makes personal finance simple, keeps shared expenses fair and transparent, and turns household money management into a fun, accountable experience.

Problem

Problem

Flatmates struggle with money due to overspending, splitting confusion, awkward conversations about uneven budgets, and lack of simple tools for transparent, balanced shared finances.

Solution

Solution

I designed an app that makes flatmate budgeting transparent, fair, and fun. It auto-tracks behaviours and uses AI to scan bills for instant splitting, with positive nudges that make flatmate budgeting transparent, fair, and stress-free.

Constraints & Trade-offs

Constraints & Trade-offs

A 1-day sprint meant skipping primary research and working from my own experience as a flatmate plus 2-3 quick conversations. The goal was a directionally-correct concept, not a production-ready spec. Decisions I'd revisit with more time are noted at the end.

What I'd revisit

What I'd revisit

  • The 'gamified nudges' angle deserved a separate exploration

  • Building trust in shared finance space is crucial & onboarding is where to build it

  • With more time, I'd validate the bill-scanning UX with actual receipts - here, I designed assuming image to text recognition accuracy I didn't test
