Our primary audience included privacy-conscious individuals aged 20-45 who frequently shared expenses. To understand their needs, we conducted:
Surveys: Reaching 52 respondents to gauge attitudes towards expense tracking and privacy.
Interviews: Engaging 13 participants for deeper insights into shared expense pain points.
Competitor Analysis: Evaluating four leading expense-tracking apps to identify gaps in privacy features and ease of use.
Key Research Findings
Privacy Concerns: Users worried about how their financial data was stored and shared.
Debt Tracking Challenges: Partial payments and splitting costs often led to confusion.
Awkward Payment Conversations: Users felt stressed about requesting overdue payments.
Categorisation Needs: Expense categories often lacked flexibility or clarity.

Using the Jobs to be Done framework we identified core user goals:
Maintain Control: Ensure sensitive financial data is secure.
Simplify Tracking: Provide a clear and confusion-free way to track shared expenses.
Ease Conversations: Create diplomatic ways to manage overdue payments.
Handle Complexity: Enable users to split expenses in diverse, nuanced scenarios.
Two distinct user personas emerged:
Young professionals sharing housing expenses, prioritising simplicity and automated reminders
Security-conscious family managers seeking detailed tracking and advanced privacy features

1. Mapping User Task Flows
I identified key user task flows, including: Expense entry, analytics, group management, debt settlement and privacy settings. I prioritised features based on user needs and pain points.
2. Wireframes for Peer Review
I created low-fidelity wireframes for review by design colleagues and stakeholders.
And gathered feedback for possible improvements and consideration.
3. Usability Testing
After iterating on the design and creating a low fidelity prototype, I conducted usability testing to identify areas for improvement
I discovered a user need for adding either group or individual expense from the same button. Users appreciate the option to customise analytics. Some users need some extra explanation for privacy settings and back up options.
4. Iterations and High Fidelity Prototype
I introduced changes to the final prototype, including:
A submenu to choose individual vs group expense, accessible from the add expense button.
More advanced analytics options with customisable settings.
Onboarding explains enhanced privacy and self custody of user data.
Users get reminders to back up data. These reminders are customisable.
