Diplora is an accessibility-first mobile concept for elderly Holter monitor users. The core design goal was to reduce anxiety and confusion by emphasizing device status clarity over complex medical detail.
Through interviews, surveys, and iterative testing, the product direction focused on readability, clear onboarding, reliable Bluetooth feedback, and simplified symptom logging.
The outcome is a validated UX direction and working MVP foundation that can scale toward production while maintaining clinical boundaries and inclusive usability.
Research revealed critical barriers preventing elderly users from engaging with health monitoring apps. The findings directly informed all design decisions.
Built Diplora's visual identity and established accessibility-first design standards as the foundation for all interface decisions.
Using the MOSCOW method, I prioritized features based on accessibility and clinical validation requirements. Must-have features address the core needs identified in research.
Conducted comprehensive mixed-methods research to understand both clinical requirements and elderly user needs. The research phase produced detailed documentation that informed all subsequent design and development decisions.
Comprehensive review of WCAG 2.1 AA standards, elderly UX research, and medical device regulations to establish accessibility requirements and compliance frameworks.
Evaluated 6 device-connected health apps (AliveCor, myPhonak, Garmin, Omron, Apple Health, FreeStyle) to identify accessibility gaps and opportunities.
Interviewed cardiologists and GPs to gather clinical requirements, understand device limitations, and validate that the app shows device status only (never diagnostic information).
Conducted in-depth interviews with elderly Holter monitor users (70+) to understand real-world pain points, anxieties, and what actually builds confidence with monitoring devices.
Quantitative survey with 50 respondents aged 18-75+ on health app usability, revealing that 54% find apps too complicated and 70% want "Device Working" confirmation.
Reviewed existing Figma designs with Diplora stakeholders to validate design direction and gather feedback from the company team before prototyping.
Two primary user personas informed the design, representing the distinct needs of elderly patients and their healthcare providers.
Represents elderly patients aged 65+ who prioritize device reassurance and simple operation over comprehensive medical data.
Healthcare professionals and caregivers who need diagnostic data access while ensuring elderly users have simplified, reassuring experiences.
Conducted iterative user testing with elderly users (ages 56-70+) to validate accessibility-first design patterns. Six major design iterations addressed user feedback and expert recommendations.
The design underwent six major iterations based on combined feedback from user testing, expert review, and internal stakeholder input. Each iteration was informed by real user behavior and expert guidance.
Issue: Test users confused by "Add Complaint"—Faye thought it meant complaining about the sensor itself
Change: Renamed to "Log Symptom" throughout the interface; "Detected Activity" → "Activity History"
Impact: Users immediately understood each button's purpose
Issue: Placeholder icons didn't clearly indicate function; confusing for elderly users
Change: Replaced unclear icons with standard health app iconography; added text labels to all navigation items
Impact: Functions became immediately recognizable
Issue: Mildred couldn't find instructions when needed; Ben requested "easy Help button"
Change: Added visible "Help" button to main navigation, always accessible from home screen
Impact: Users can access instructions at any point without navigating through settings
Issue: Large battery indicator took significant space; Mildred said "It's too big"
Change: Reduced battery to small status indicator in persistent status bar; only draws attention when charging threshold reached
Impact: Refocused home screen hierarchy on actionable items, reduced visual clutter
Issue: Separate tabs for "Review Alerts" and "History" with filtering options was overcomplicated
Change: Combined into single unified list; actionable items emphasized, removed unnecessary filtering
Impact: Cleaner, less technical interface that's easier to navigate
Designed high-fidelity prototypes based on feedback from low-fidelity testing. These detailed, interactive prototypes incorporated refined design elements and enhanced functionality, providing an accurate representation of the final product ready for user validation.
Built a fully functional Flutter MVP with Bluetooth Low Energy connectivity, working symptom logbook, and movement simulation system. All code follows accessibility standards and uses scalable architecture patterns.
