Mobile-First Diagnostics with FootPlus at the Core

Future Sense is an MVP mobile app designed for doctors and hospitals to manage patient diagnostics—centered around FootPlus, an in-house solution that enables Peripheral Artery Disease (PAD) detection in ~8 minutes.

4 weeks

From scattered patient data to a unified diagnostic system

Core Clinical Flows

Streamlined patient management, testing, and reporting into clear mobile flows

2–3 iterations

Validated and refined with doctors and stakeholders

Reduced complexity

Streamlined diagnostics and patient management into one system

My Role

UX Designer — designed end-to-end mobile flows, built the design system, and delivered high-fidelity prototypes in Figma

Approach

Structured diagnostic workflows into a FootPlus-first, scalable mobile app through stakeholder alignment, iterative prototyping, and system-driven design

Stakeholder Collaboration

Stakeholders and doctors acted as users—shaping workflows, testing the app, and ensuring alignment with real clinical needs.

Diagnostic inefficiencies stemmed from unstructured workflows and poor visibility—making it harder for doctors to perform fast, consistent, and confident assessments.

KEY INSIGHT

01 — THE PROBLEM

Unstructured Diagnostics & Poor Visibility in Clinical Workflows

The Problem:
Doctors and hospitals lacked a mobile-first system to manage patients and conduct diagnostics efficiently. Critical workflows like PAD testing, patient data access, and reporting were not structured—leading to delays and inconsistencies during consultations.

The Goal

Design a mobile-first, role-based platform that prioritizes FootPlus, structures diagnostic workflows, and enables fast, reliable patient management.

Key Observation

No unified system for patients, diagnostics, and reports
Core product (FootPlus) was not clearly prioritized in workflows
Patient data and vitals were not instantly accessible
Diagnostic steps lacked guided, consistent execution
Multiple user types required role-based access and clarity

02 — Discovery & Problem Framing

Prioritizing Core Diagnostics in a Mobile Context

Stakeholder discussions (MD team and doctors) highlighted that the platform needed to center around FootPlus while supporting end-to-end patient workflows.

Direction & Constraints

Stakeholders set a clear expectation:

Mobile-first usage in real clinical environments
Multiple users: doctors, hospitals, partners
Need for quick PAD diagnostics (~8 minutes)
Must support patient management + testing + reporting
MVP required to be simple, scalable, and easy to adopt

This reframed the challenge from managing scattered clinical tasks to designing a FootPlus-first, structured mobile diagnostic experience.

Signals & Insights

FootPlus needed clear prioritization as the core value driver
Diagnostic workflows required step-by-step guidance for consistency
Patient data had to be instantly accessible during consultations
Complex processes needed simplification for mobile usage

Shift from supporting multiple features equally → to prioritizing FootPlus within a simplified, guided mobile experience.

Hypothesis & Opportunity

Based on available inputs, key hypotheses emerged:

Prioritizing FootPlus would increase adoption and usage
Guided flows would improve diagnostic accuracy and consistency
Centralized data would enable faster, more confident decisions

This revealed a clear opportunity:

Shift from fragmented, feature-led interactions → to a FootPlus-first, structured diagnostic workflow.

Key Takeaways

Clinical efficiency depends on prioritizing core diagnostics and structuring workflows for speed, clarity, and mobile use.
A FootPlus-first, system-driven approach can reduce complexity and enable reliable, scalable diagnostics.

03 — Design Solution

From Disconnected Tasks to a FootPlus-First Mobile Experience

The app was designed to prioritize FootPlus as the primary action, supported by structured flows for patient management and diagnostics.

Low-fidelity wireframes were validated with stakeholders, followed by high-fidelity mobile designs and prototyping.

Key Screens (Mobile)

1. Login / Signup

Role-based onboarding for doctors and hospitals
Quick access to relevant dashboards

2. Dashboard (FootPlus First)

FootPlus positioned as the primary CTA
Secondary access to patients, reports, and actions

Why this works
Drives immediate access to the core diagnostic feature and reduces navigation friction.

3. FootPlus (PAD Test Flow)

Guided, step-by-step diagnostic flow
Designed for completion in ~8 minutes
Clear progress and instruction states

Why this works
Ensures consistent and reliable test execution in time-sensitive environments.

4. Patient Management

Add new patients
Fetch existing patient data, reports, and vitals

5. Additional Tests

Blood pressure, blood sugar, weight, height
Integrated as supporting diagnostics

6. Reports & Insights

View patient history and vitals
Doctor-level summary reports

7. Hospital Plan & Wallet

Doctors and hospitals can select and purchase pricing plans
Manage wallet balance and track usage

Why this works
Enables seamless onboarding and usage by integrating plan selection and payments directly within the app.

Key Design Decisions

Positioned FootPlus as the primary user action
Designed guided diagnostic flows for consistency and speed
Simplified complex workflows into mobile-friendly steps
Validated flows through low-fidelity before high-fidelity
Built a scalable design system for future expansion

04 — The Design System

Optimized for Mobile Consistency and Scalability

A reusable design system ensured consistency across all screens.

COMPONENTS

Forms and input fields for patient data
Cards, tables, and data views
Buttons, dropdowns, and selectors
Tabs and mobile navigation

Foundations

Typography optimized for readability on small screens
Color system for clarity and state indication
Spacing system for touch-friendly interactions

Why it Matters

Ensures visual and interaction consistency across all pages
Speeds up design and development through reusable components
Supports scalability as new features and workflows are added
Improves usability in complex, data-driven environments

05 — Testing & Validation

Validated through Stakeholder & Doctor Reviews (MVP Phase)

As an MVP, validation was conducted with MD, stakeholders and a panel of doctors acting as primary users.

Stakeholder Review

High-fidelity Figma designs were reviewed with stakeholders to ensure alignment with real procurement processes.

Strong alignment on FootPlus-first approach
Positive feedback on guided PAD test flow
Validation of quick patient data access
Confirmed usability in real clinical scenarios

Outcome

Stakeholder and doctor validation confirmed the solution is practical, aligned with real clinical workflows, and ready for implementation. The MVP establishes a strong foundation to scale FootPlus, with real-world user testing planned in future iterations.
