Overview
Overview
Overwatch is a seizure-detection application designed to help patients with epilepsy (and their families or caregivers) track, monitor, and understand seizure events in real time. The app uses motion detection, machine learning, and location tracking to send notifications or alerts, offering support in preventing injuries or unattended seizures.

Originally launched in a basic format, Overwatch had a few strong points—real-time seizure alerts and location monitoring—but it needed significant improvements to address user needs.

Design Process
My design process for the Overwatch Digital Health app was rooted in iteration and empathy. I began by engaging with users to understand their daily challenges, which shaped the creation of personas and journey maps. These insights became the foundation for early wireframes and prototypes.
Through ongoing usability testing, I refined the designs to improve clarity, usability, and alignment with clinical needs. Close collaboration with developers and healthcare professionals ensured that the solutions were not only intuitive but also practical and clinically relevant. The result was a design that empowers users while effectively supporting epilepsy management.

Before & After Comparison
The Before version feels more static and text-heavy, while the After redesign is structured, dynamic, and prioritizes key metrics at a glance. The redesign follows modern health app patterns (dashboard style), giving users more actionable insights upfront.
Before
Linear layout with long sections and little hierarchy.
Important actions (medication, journal, emergency) were buried.
Heavy reliance on text, low scannability.
Seizure logs were detailed but cluttered.
After
Dashboard-style layout with prioritized modules.
Clear CTAs (Take Now, View Journal, Start Session) streamline tasks.
Seizure logs simplified with severity labels and collapsible details.
Stronger visual differentiation through color, spacing, and icons.
Bottom navigation improves quick access to core features.

Quantitative Research
Usability testing showed strong improvements with the redesigned Overwatch Digital Health app. The task error rate decreased to 12%, while average task time improved to 1.3 minutes, highlighting greater efficiency and clarity. The Net Promoter Score (NPS) reached 76%, reflecting high user satisfaction.
Two minor non-critical issues were noted—sync delays with wearables and minor UI overlaps—neither affecting task completion, but providing direction for future refinements.

User Persona
As part of our research, we created two user personas to capture the needs of our core audience. Informed by surveys and interviews, these personas highlight user goals, challenges, and motivations, ensuring the Overwatch Digital Health app redesign stays grounded in real experiences. They served as a foundation for feature prioritization and design decisions, directly addressing key scenarios in epilepsy management.

User Survey
Our survey revealed that most users, particularly those aged 25–34, rely on the app daily or weekly as part of their daily health routine. While navigation felt easier for many, users highlighted the need for faster seizure reporting, asking for features like voice-to-text and simpler input forms. These insights guided our redesign to make the app more intuitive and supportive in real-life use.
