MobileODT:
Cervical cancer detection app
Type: Healthcare / Medical devices
Role: Lead UX/UI
Scope: Android app - handheld device controller
A digital ecosystem that enables fast, affordable and precise cancer detection.
As lead UX/UI designer at MobileODT, I was responsible for all user-facing aspects of the EVA System—a platform that helps healthcare professionals detect and treat cervical cancer. At its core is the EVA device, a mobile imaging tool operated via the Android-based EVA app. My first goal was to evolve the app from a developmental prototype into a user-friendly, production-ready product.
The EVA app enables users to capture images, log medical data, consult with peers, and annotate visuals. It supports multiple user types—from nurses creating daily patient cases to supervisors reviewing and advising on them.

My first goal at MobileODT was to understand how our beta testers were actually using the EVA app. While we had access to usage data, I needed deeper insight into real-life workflows and user needs. I conducted user interviews and built personas based on our testers, uncovering key opportunities—particularly in the OB/GYN nurses’ triage workflow—to improve usability and make the product more efficient.

Structure and Navigation
After several rounds of wireframing and prototyping, we launched a new version of the EVA app, redesigned around the core triage workflow: collecting patient details, capturing images, and navigating a clinical decision tree. While the app emphasizes these three main steps, a flexible tab-based navigation system allows users to follow their own path through the process, adapting to different roles and real-world scenarios.

After several rounds of live testing and refinement, we introduced a chat feature to the app. It leveraged the phone’s connectivity to help novice nurses get real-time advice from more experienced colleagues or administrators—turning the app into a tool for both clinical documentation and peer support.

Design system
While designing the EVA app’s interface, I also developed a cohesive visual language for MobileODT’s entire product suite. The design system drew from Google’s Android UI principles, combined with the company’s brand guidelines to ensure consistency across platforms and communications.
