App Redesign

Overview:

The goal of this project was to redesign Acasa, a bill-sharing and shared living expense management app, to create a more cohesive and insight-driven experience.

The redesign focused on improving expense tracking, increasing transparency in shared finances, and enabling users to better understand their spending habits while managing household responsibilities efficiently.

Project Duration:

8 weeks

Role:

UI/UX Designer

• Led end-to-end redesign (research → design → testing)

• Improved user flows for expense tracking and bill splitting

• Designed wireframes, prototypes, and final UI

Tools Used:

• Figma (UI/UX Design & Prototyping)

• Miro (User flows & mapping)

• Pen & Paper (Ideation)

Process:

1. Research & Discovery:

• Identified key issues in the existing experience:

• Lack of clarity in tracking shared expenses

• Limited visibility into individual vs group spending

• No insights into spending behaviour or patterns

• Fragmented experience across features

• Defined opportunity:
  → “How might we simplify shared expense management while helping users make better financial decisions?”

2. Wireframing & Prototyping:

• Redesigned core flows:

  • Expense logging and splitting

  • Household overview

  • Individual contribution tracking

• Created wireframes focusing on:

  • Clear financial summaries

  • Simplified group interactions

  • Reduced friction in adding and settling expenses

• Built interactive prototypes to test usability and navigation

3. Visual Design:

• Introduced a clean, structured UI:

  • Clear hierarchy for financial data

  • Dashboard-style overview for quick insights

  • Consistent components and visual patterns

• Key improvements:

  • Visual breakdown of spending (individual vs shared)

  • Improved readability of transactions and balances

  • Cohesive design system across all screens

4. Usability Testing:

• Conducted prototype testing with 5–6 users

Key Observations:

• Users preferred clear summaries over detailed transaction lists

• Visual insights improved understanding of spending habits

• Simplified flows reduced confusion in bill splitting

Iterations Made:

• Enhanced dashboard clarity

• Simplified expense input flow

• Improved labelling and grouping of financial data

5. Implementation & Launch:

• Delivered high-fidelity mockups and interaction flows

• Defined a scalable design system for future features

• Validated usability improvements through testing

Results:

(Prototype-based outcomes)

• Improved task clarity in expense tracking and splitting

• Increased user confidence in managing shared finances

• Positive feedback on financial insights and dashboard usability

Key Takeaways:

• Financial apps require strong clarity and trust through design

• Visual summaries are more effective than raw data for decision-making

• Simplifying group interactions reduces friction in shared environments

• Cohesive design systems improve overall usability and scalability

Next Steps:

• Add budgeting and saving insights

• Introduce notifications and reminders for settlements

• Enable deeper analytics on spending behaviour

• Explore integrations with banking or payment platforms
