I saw an opportunity to improve the popular financial mobile app Splitwise by adding a group budgeting feature.

As a long-time user of the app, I knew it was great at managing group expenses and repayment. However, the latter often raised concerns about unexpected costs or exceeding group members’ intended budgets.

I began this project with these goals in mind:

  • Simplify financial planning among group members

  • Foster a sense of fairness and trust within groups

  • Lessen discomfort typically associated with financial discussions

PROBLEM

When members of a group share expenses, unexpected high costs can cause friction, delays, and disagreements over reimbursements and, in worst cases, damage relationships.

RESEARCH & ANALYSIS

I first sought to understand how Splitwise users budgeted for their shared expenses, if at all.

After analyzing competitors, conducting surveys, and interviewing past and present users, I learned these are the most common frustrations users have when sharing expenses:

  • Uncertainty about final costs

  • Forgotten debts

  • Reluctance for members to add expenses

  • Discomfort when requesting repayments

Key Insights

Users typically enjoy sharing the costs of group activities but dislike negotiating costs or handling reimbursements.

Users hesitate to discuss finances with group members because they don’t want to appear overly cautious or less fun.

THE SCOPE

Defining the design

Based on my research findings, I worked on developing a solution that would:

  • Painlessly prompt group budget conversations

  • Respect and acknowledge individual and collective financial sensitivities

  • Engage all members in financial planning

  • Encourage prompt debt repayment to strengthen trust and relationships

DESIGN & PROTOTYPE

Fitting it all in

In my first iteration of the new feature, I…

  • Added a toggle to enable budgeting in new groups

  • Implemented a "Spending Style" questionnaire with a summary of preferences to align group expectations

  • Developed a group mindfulness agreement

  • Provided a way for users to add proposed / future shared expenses

USABILITY

I tested the feature in an interactive prototype with seven target users.

I asked testers to do the following:

  • create a budget-enabled group

  • add a new planned expense

The feedback received was diverse. Some suggested increasing the flexibility of payment options and creating notifications for unaffordable expenses. The clarity and usefulness of the Group Preferences Summary were also highlighted for improvement.

The second iteration of my designs had:

  • Improved microcopy

  • Refined questionnaire questions

  • Enhanced UI for better clarity and visual hierarchy

By providing tools to anticipate financial surprises, Splitwise could better support healthier, more enjoyable group interactions.
