TapGo

TapGo began with observing the difficulties my grandparents faced using digital services. As an early self-initiated UX/UI project, I explored the complete design process, from user research and journey mapping to accessible mobile interfaces and prototyping. I later revisited and refined the experience with stronger design skills.

Many shopping apps assume users are comfortable with digital conventions and complex navigation. For older adults, small touch targets, dense information, and unclear feedback can make everyday tasks frustrating. These barriers can undermine confidence and make independent shopping unnecessarily difficult.

The challenge was not simply making everything bigger. I needed to reduce cognitive and physical effort while preserving a complete grocery shopping experience. The interface had to accommodate varying levels of digital literacy, visual ability, and touch precision without assuming every older adult needed the same solution.

I introduced adjustable text sizes, high-contrast themes, and larger interaction areas to support different accessibility needs. Task-focused navigation and guided onboarding reduced uncertainty, while clear feedback and an emergency-assistance feature provided additional support. These decisions made accessibility part of the overall product experience.

Designed a complete conceptual shopping experience integrating accessibility across navigation, typography, interactions, and personalization. The project produced research artifacts, user flows, prototypes, and accessible UI patterns. Revisiting the concept later also allowed me to improve its visual consistency and interaction design.

TapGo taught me that accessibility extends beyond font sizes and contrast. It requires understanding confidence, familiarity, cognitive load, and user control. Revisiting my earliest UX work also reinforced the importance of iteration and showed how stronger design thinking can improve an existing concept.
