Design for new budgeter
Green Budget helps users build healthy money habits, reach savings goals, and avoid running out of cash. From first-time budgeters to students and new employees, it offers smart tools like expense tracking, savings targets, spending alerts, and daily allowances. Success is measured by reduced overspending, goal completion, and end-of-cycle balances.
Problem & Solutions
- People often overspend on snacks and shopping because tracking expenses feels overwhelming, leaving them unprepared for emergencies.
- Self-funded students struggle to save from daily spending, making it hard to reach future goals like travel.
- Newly employed users find it hard to balance daily expenses and loan payments, with little left to save before payday.
✓Track & Save
Green Budget helps reduce
unnecessary spending and build
savings through simple expense
tracking.
✓Hit Saving Goals
Automate loan payments and
calculate daily limits to avoid running
out of money.
✓Manage Daily Budget
Set income-based goals, get
reminders, and pause non-essential
spending to save more.
Design Process
I followed a human-centered design process, moving through the five steps.

Quantitative Research
I interviewed several new budgeters—people who are new to managing their own money—to understand their budgeting needs and personal financial habits.

User Persona
I synthesized this persona from user research and used it to guide feature prioritization and design decisions throughout the project.

Impact Effort Matrix
I used an Impact–Effort Matrix to prioritize ideas by balancing user value and implementation effort, helping me identify high-impact, low-effort features to focus on first.

Competitive Audit Analysis
I conducted a competitive audit to compare existing budgeting apps and identify strengths, weaknesses, and gaps in the market, helping inform feature opportunities and differentiation for my design.

Information architecture
Based on earlier research, I organized the information architecture into clear, goal-oriented sections to help users easily track spending, manage savings, and review insights.

Sketches
Based on earlier research and information architecture, I sketched key feature flows to quickly explore layouts, interactions, and user journeys before low-fidelity design.

Low-fi prototype
Based on the earlier sketches, I created low-fidelity prototypes to validate layout, user flows, and core interactions before moving into high-fidelity design.









Usability test
I used unmoderated usability testing with Maze to evaluate the low-fi and early hi-fi prototypes. The results showed strong task completion and satisfaction, while identifying issues in clarity and visual hierarchy that guided further design improvements.
Test result
75% of participants were satisfied with the functionality of the low-fidelity prototype
75%
60% of participants said they would consider subscribing to the full version of the app.

80% of participants successfully completed the task during the unmoderated usability test.

Confusion
Nearly half of the participants felt confused about the budget reallocation feature, with some getting lost during the process.
Clarity
The card layout makes it visually difficult to distinguish between categories, and the color scheme can be disorienting.
Hierarchy
Some features appear visually cluttered, making it difficult to distinguish between primary and secondary elements.
Iteration
Based on usability testing insights, I iterated on key flows to improve clarity, guidance, and visual hierarchy.
Confusion → Guidance



→
→
Ambiguity → Clarity



→
→
Flatness → Hierarchy

Interaction Flow
I designed four core interaction flows—Saving, Budget, Analytics, and AI—to guide users through goal setting, expense tracking, insights, and personalized assistance with clarity and efficiency.
Saving Flow
Use a simple, visual saving flow to help users easily reach their saving goals.
Budget Flow
Use a clear, automated budget to track every expense and its category.
Analytics Flow
Use intelligent AI scoring to optimize spending habits and improve personal financial efficiency.
AI function Flow
Use an AI assistant provides personalized, daily spending recommendations.
The Second Round Usability test
I ran a second round of usability testing to validate the design improvements, which showed higher user satisfaction, strong subscription intent, and improved accessibility.

Self reflection
This was a meaningful project that tackled common challenges faced by first-time budgeters.Throughout the design and implementation process, I strengthened my core UX skills—especially in card-based UI design. I explored how to create diverse card layouts across different screens while maintaining a sense of consistency and visual harmony.
Initially, the design was built around a green color scheme to match the theme. However, considering accessibility concerns—especially red-green color blindness—I eventually switched to a blue palette. This decision deepened my understanding of accessible design and reinforced the importance of inclusive user experiences.
