👉🏻The product team approached us with a bold requirement:

How might we design a low-friction digital product for healthy habits

The Real Problem

The correlation between UK's rising chronic illnesses and fear to stay consistent

The correlation between UK's rising chronic illnesses and fear to stay consistent

The correlation between UK's rising chronic illnesses and fear to stay consistent

People are living longer, but most approaches in healthcare still focus on treating illness after it appears rather than preventing it. Most consumer health & fitness apps assume a body gets stronger and improves capacity. With chronic diseases on the rise, a need was identified to develop a low-friction app that motivates people with chronic conditions to sustain healthy habits, track progress and get insights to thrive.

As part of the NHS’s long-term shift towards preventive care, this project is funded as third-party app for NHS social prescribing and integrated care system units.

Target Users

Non-Wearable Customers

Dissatisfied Wearable Customers

We focused on people who feel dissatisfied with health metrics provided by existing solutions in the market. They are seeking clarity and confidence with easy to understand insights that support healthy habits.

My Approach

👉🏻 As project lead, I led UX/UI design, facilitated research and guided strategy in collaboration with the product owner and healthcare experts.

👉🏻 To ground design in clinical realities and real user needs, I also included collaborative "co-discovery" session with NHS healthcare professionals (subject experts) and mini-ideation session involving people with chronic conditions to gain insights on unmet needs.

👉🏻 Reframed customer needs -> people's aspirations

👉🏻 Refined AI tone with more empathy and trust.

👉🏻 Discovery -> Rapid concepts -> Design -> Test -> Iterate -> Hand-off

MVP Scope

In scope

Onboarding, Goal Setting, Tracking Progress

Out of scope

Clinician-facing dashboard, Medical diagnosis

I proposed to get an intial review from NHS healthcare experts to understand how this app can fit within clinical system. This helped us to identify what is the project scope, why personalised insights will be helpful and how it can be implemented in the regulated system.

Product Strategy

Turning barriers into opportunities

Alongside Product Owner, I helped shape the Product Strategy. I approached these problems through the longevity lens, aiming to enable longer, healthier lives and improve wellbeing outcomes. Since evidence suggested lack of motivation to big health & lifestyle "overhauls" and poor digital health literacy as key barriers to adherence in existing solutions, reducing onboarding friction and providing micro doses of health milestones became a core UX goal.

Early research shows low adherence to existing digital health programs, so increasing engagement was a core goal.

Design Thinking Workflow

Survey

Survey

108 respondents shared their experience with existing solutions and their unmet needs

Co-creation

Facilitated a workshop with healthcare experts, product owner & engineer to understand the opportunity and align priorities

Focus Group

Facilitated a workshop with 20 target users to uncover coree needs and create wireframe concepts together

Design Scoping

Define two hypotheses with stakeholders, fleshed out core app features and user flow

Design Phase 1

Rapid UX mockups -> UI design -> prototyping of core screens for first use and regular engagement

Usability Testing 1

Alongside UXR, tested & analysed feedback from ~9 users to evaluate UX, task completions and usability (SUS)

Design Phase 2

Refined high-fidelity prototype based on feedback

Usability Testing 2

Tested & analysed feedback. Significantly improved UX, task completions and usability (SUS)

Hand-off

Final prototypes and style guide documentation handed over for development

User Research & Analysis

Survey

Survey

Survey

108 people (ages 31–85) with chronic conditions shared their opinions, motivations and frustrations with existing digital solutions. Through analysis, we identified the key topics to probe into more deeply in focus groups and challenge unfounded assumptions:

Balancing patient needs while meeting clinical regulations

Building upon survey findings, we identified the key topics to probe into more deeply in focus groups and challenge unfounded assumptions

  1. Mini-Ideation Workshop with Target Users

    Participants
    Diverse patient representatives (high to low digital confidence)

    Key Insights (Generalised due to confidentiality)
    Despite differences in lived experiences, participants shared some goals, including following personal goals, social engagement to overcome isolation and access to professional advice.

The feedback analysis from both focus groups highlighted key considerations for the app features including:

Warm, friendly tone

Adjustable Goals

Personalised insights

  1. Consultation and co-creation with healthcare experts


    Participants

    • Experienced NHS GPs, social prescriber and health coaches
    • Product Designer, Product Owner and Engineer


    Key Insights (Generalised due to confidentiality)
    Healthcare professionals see value in an app that tracks wearables data and provides low risk, non-medical AI insights. The key goal being patient independence and preventative guidance. Together, we built a strategy to integrate this app in the healthcare workflow.

Healthcare Professional Perspective (HCPs)


Experience Range: GPs, social prescribers, care coordinators, health coaches

Key Insight:
HCPs see value in a non-medical app that empowers patients to stay engaged through non-medical assessment and goal setting, aligning with broader preventative care and patient independence.

Identified where this app can be fit into the current system.

AI Insights and Goal Suggestion

AI Summary is prioritised on home. When setting a goal, there is flexibility to choose between a custom or suggested goal to maintain user autonomy. User Insights from Usability testing R1: • AI insights suffered from low trust (lack of transparency on how much data are the insights based on) • Tooltip hid the explanation one click away.

AI Insights and Goal Suggestion (Iterated)

✅ Utilised the logic of low, moderate, high confidence AI summary from system architecture and made it visible in the frontend UI with chips. ✅ Visible origin of AI suggestion (past data and NHS guide) at the point of decision, not one click away, to improve perceived trust and more clarity. Impact measured in Usability testing R2: • Overall confidence in AI suggestion: nearly 79%. 
 • User trust in AI suggestion: 40% increase in opting for suggested goal over custom goal
 • Reduced Time-to-Value: Time taken to set a goal (from avg 30 s to ≤ 22 s)

Regulations and Disclaimers

During onboarding, users must fully understand what’s included and what’s not before they fill out any information.

Regulations and Disclaimers (Iterated)

✅ For compliance, a short description about each regulated instrument is included and answers are mapped with regulatory standards. This helps to establish a baseline during clinical appointment. Design iterations and impact: • Improved data capture quality by tagging each option with 0-1 or L1-L5 scale

Conclusion

Conclusion

Following two rounds of usability testing, the design iterations produced improvements in usability (SUS), task completions. User confidence and trust scores increased with more transparent AI insights. Overall, user experience was described as supportive, helpful, reassuring and intuitive.


After launch, customer activation rates and feature adoption would be measured in 30 days, 6 months and 12 months intervals.

Although MVP was focused only on B2C patient-facing intervention, gathering feedback from both patients and trusted healthcare experts early in the design process helped with strong product positioning to ensure the app remained clinically grounded and can be connected with clinical workflows. This approach enabled us to deliver meaningful value with strong adoption potential.

Following two rounds of user testing, the redesign produced clear improvements in usability and perception metrics. User satisfaction increased, and transparency around AI insights reduced confusion and increased trust. Desirability feedback was strongly positive with users describing the experience as supportive, helpful, reassuring and intuitive.
