Design iterations

01

Paper Prototype

Category-First, No Brand, No Price. Reduced cognitive load but users struggled to locate items and lacked confidence without price info.

02

Low-Fi Prototype

Item-First, Still No Price. Navigation improved but users still felt unsure without price reference.

03

Hi-Fi Prototype

Item-First + Lowest-Price Display. Showed lowest available price per item. Reduced uncertainty, increased trust.

Budget Ring Dashboard

A spending visualization that helps shoppers understand budget, planned purchases, and remaining balance before checkout.

AI Receipt Scanner

A scan-and-verify flow that turns receipts into budget history without asking users to manually re-enter every item.

Price Transparency Alerts

When substitutions change cost, the interface explains the difference before confirmation so shoppers can stay in control.

How I got there

Heuristic Evaluation

Assessed usability against Nielsen's 10 heuristics to identify structural pain points early.

Usability Testing

Task-based sessions with 5 participants across 3 prototype iterations to validate navigation and clarity.

User Interviews

Semi-structured interviews with SNAP/WIC users to surface real emotional and cognitive friction points.

Onboarding

The entry flow acts as a setup wizard — users configure dietary restrictions and preferred stores so every feature downstream is tailored to them.

Reflection

What worked

• Price transparency reduced uncertainty

• Budget ring created emotional clarity

• Receipt scanner removed highest friction point

What’s next

• Live API connections to store inventories

• SNAP/WIC database integration

• Edge case error handling for OCR failures
