Project Goals
Project Challenge
Build one clear home for shared spending.
SplitX was created to eliminate the friction of manually tracking group payments across notes, spreadsheets, and messaging threads. The objective was to make shared spending instantaneous to log, intuitive to audit, and stress-free to settle.
Simplify financial logic without hiding trust.
The core challenge was balancing radical simplicity with strict mathematical transparency. Users should never need to parse accounting jargon, but they must always verify exactly why they owe — or are owed — a specific balance.
Our goal was to turn complicated group-expense calculations into a calm, human experience where every balance has a clear story behind it.

Approach & Methodology
I structured the project around the complete expense lifecycle: creating a group, adding an expense, selecting a split method, reviewing running balances, discussing discrepancies, and executing one-tap settlements.
User Discovery & Insights
Qualitative research focused on the recurring questions users face in group finances: “Who paid?”, “Who owes me right now?”, “How was this split calculated?” and “Has this payment cleared?”

Engineered for dense financial clarity, high legibility, and geometric balance.
A disciplined typographic hierarchy keeps transactional numbers, currency symbols, member names, and actionable balances instantly parseable. Large primary amounts take visual priority, while timestamps and metadata remain crisp and unobtrusive.

Design Phase
High-Fidelity Product UI
The visual language establishes a calm, neutral foundation paired with vibrant electric green for positive balances and primary call-to-actions. Generously rounded card surfaces prevent dense numerical data from feeling sterile or overwhelming.
Every high-frequency flow adheres to predictable component patterns for amount entry, member tagging, split adjustments, and receipt verification — reducing cognitive overhead as users move across shared groups.
