OVERVIEW
OVERVIEW
APTNER pass is a service embedded within APTNER's app, designed to help residents reserve communal activities and amenities in advance. As the sole UI/UX Designer in a team of five (Project Manager, Frontend Engineer, Backend Engineer, and pass Customer Service Manager), I was responsible for revamping the user experience for APTNER pass users to v2.0. This involved creating a seamless user flow and integrating a user interface that aligned with APTNER's existing design system. I took full ownership of the project across all stages, from research and design to execution, making numerous design decisions that optimized key user touchpoints.

PROBLEM STATEMENT
PROBLEM STATEMENT
APTNER pass is designed in an aspect that is not uniform with the rest of the app’s design system and has a convoluted user flow that disrupts the user experience.
APTNER pass is designed in an aspect that is not uniform with the rest of the app’s design system and has a convoluted user flow that disrupts the user experience.
While the APTNER mobile app has undergone multiple redesigns over the past five years, APTNER pass had remained untouched. The original user interface, developed by engineers without user research, lacked empathy and convenience.

Identifying opportunities, frustrations, and needs.
By defining the information architecture of the existing UX of APTNER Pass v1.0, interviewing residents of Ansan Granx1—one of the largest and most representative apartment complexes using our service—and analyzing customer service invoices collected by our team, I identified key areas that frustrated our users the most and needed redesign of the user flow.

Key Insights and Design Decisions
Key Insights and Design Decisions
Design inconsistency
Design inconsistency
Design inconsistencies between APTNER and APTNER Pass caused confusion among users, especially in finding the Pass service within the APTNER mobile app. Additionally, the typography and colors were inaccessible to the full target audience, aged 20 to 60.

Categorized into four reservation types.
Categorized into four reservation types.
From my research, I identified that all amenity reservation methods can be categorized into four types: room, seat, cafe, and program. Focusing on these, I recreated the user flow to provide a simpler, more intuitive reservation process.

This simplified the UX of the APTNER pass app by creating four templates that can be easily applied across different amenities and apartment complexes. Users will find the app more familiar and easier to navigate as well, reducing confusion.

Program Type
Program Type
I improved the interface by removing a non-functional dropdown for program types and eliminating a redundant instructor profile button on the program card. By making the instructor name itself a clickable button that opens the profile pop-up, I streamlined the design, reducing confusion and simplifying the card component.

Cafe Type
Cafe Type
I added a new screen to improve user flow by separating the menu browsing and ordering processes, which were previously combined on a single screen. This change provides a wider view of menu items and eliminates infinite scrolling. I also refined the checkout process with toast notifications, ensuring a smoother and more intuitive experience.

The outcome.
After presenting my work, my team proceeded with the development and coding of the project. Due to my departure to attend a graduate program in New York, I was unable to engage fully in the development process. A few months later, my teammate updated me that the coding phase was complete and the project was awaiting deployment to the community.
