Overview
Overview
APTNER pass is a service embedded within APTNER's app, designed to help residents reserve communal activities and amenities in advance within apartment complexes. 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.

THE PROBLEM
THE PROBLEM
Instead of using the app, residents were using in-person kiosks.
Instead of using the app, residents were using in-person kiosks.
Due to inconsistent design and convoluted user flows, residents were found using the in-person kiosks over remote reservations through APTNER pass. This not only increased operational costs but also led to higher customer complaints and frustration, as reflected in support invoices.

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.

Understanding the problem.
Understanding the problem.
I first approached the problem by mapping the information architecture to understand the existing user flow, where I identified that there could be up to 29 different amenities within an apartment complex. I also found that these amenities share common tasks, which could be integrated into a unified experience.

I identified the potential to template all 29 amenities into four reservation types, with all amenities aligning to one of these predefined reservation processes.

FINAL THOUGHTS

Outcome.
Outcome.
Through multiple rounds of feedback and design revisions with the team, I received approval for the final design but resigned during development to align with my graduate school schedule.
Later, I learned that while development was completed, the project was put on hold due to additional changes requested during executive decision-making, due to the nature of startup.
