Redefining ‘mine’ and ‘ours’ in couple’s finances for friction-free, confident decisions



ABOUT THE PROJECT
The Challenge
Money talks are awkward, especially when spending habits don’t align. For dual-income, no-kids couples who aren’t quite “all in” financially but also aren’t fully separate, the lack of a fair, easy way to manage expenses often leads to friction.
The Goal
Even after nine years together, managing money as a couple wasn’t always easy. I found many others were in the same boat. I wanted to ease the tension and make managing 'ours' simple, without either of us giving up the comfort of 'mine.'
My Approach
I designed Mayo to make manage personal and shared expenses friction-free. By bridging the gap between 'mine' and 'ours,' Mayo provides clarity without compromising autonomy—helping couples focus on each other, not just the money.
THE SOLUTION
The MVP
The result is an intuitive, visually engaging app designed for dual-income-no-kids couples. In a market filled with overly technical financial tools, Mayo simplifies money management—making financial clarity accessible, even for those who aren’t deeply engaged with finance.

origin story
The Why
Money has always felt personal to me. After nearly a decade in a relationship, ‘mine’ and ‘yours’ naturally became ‘ours’—but not without its challenges. I realized many couples faced the same struggles. How do you find balance when two people have different goals, habits, and instincts around money? That question stuck with me, and I wanted to find a way to make it easier.
Here's how I did it.

Identifying The Problem
Merging finances can help couples but may spark conflict over values and spending, risking personal autonomy.

Competitor Analysis
Few financial apps support household budget sharing. YNAB is the most established, Origin offers the best UX, and Honeydue focuses on shared finances, but there’s room for more inclusive, user-friendly solutions.

Identifying The Right Audience
Dual-income-no-kids couples' finances are more linked than in casual relationships, but they’re still navigating how to manage fluctuating personal and shared expenses together.






Testing Assumptions
Insights from user interviews revealed a key need I hadn't initially considered. This challenged my assumptions and prompted me to revise my original hypothesis.

reflections & takeaways
01 — Progressive disclosure
For newcomers to financial apps, I would have liked to explore an option to gradually reveal information in to ease overwhelm.
02 — Embracing limitations
I used my lack of technical skills as a strength to develop simpler, user-focused solutions, leveraging gaps in knowledge as learning opportunities.
03 — Finding my own process
Adapting the design thinking process to fit my understanding of the problem, rather than following it linearly, proved beneficial.
