UX & UI FOR IOS APP | HEALTH
Kintra - Reaching health goals through relationship support
In conjunction with the Apple Foundation Program at RMIT, I was appointed the UX Lead of a team of 5, working on Interaction/Motion, UX research and UI design to create an iOS app that helps couples care for their health and each other in the midst of busy, emotionally demanding lives.
Turning health tracking into shared motivation
Kintra is an iOS app that helps couples care for their health and each other in the midst of busy, emotionally demanding lives.
Created as part of a human-centred design brief for Apple platforms, the app turns everyday health tracking into a shared, motivating experience built around connection.
THE PROBLEM
Despite thousands of fitness and wellness apps, most adults still struggle with consistency.
only 22.4% of adults aged 18–64 meet physical activity guidelines.
According to the Australian Bureau of Statistics,
Our research found the issue wasn’t time, it was motivation. Office workers aged 25–50 wanted to stay healthy, but after long workdays they lacked accountability and emotional support.
Many shared that their habits were closely tied to their partners, yet no product helped them build those habits together.
IMPACT
Tackled the real barrier behind health apps: lack of motivation and
emotional connection.
Merged relationship-building with health tracking to create a shared wellness journey that drives accountability and engagement.
Balanced emotional design with functionality to position Kintra as a
standout product in the health-tech market.
RESEARCH
USER INTERVIEWS
Each of us conducted our own user interviews, our participants had to be aged 25-50, and working a 9-5 job.
“I think couples would really enjoy sharing the water tracking feature, like you know how husbands are always asking their wives if she's drank water?”
KEY INSIGHTS
Physical health mattered, but consistency
was the biggest challenge.Mental health was often neglected or untracked.
All participants were in long-term relationships, with lifestyles and routines deeply intertwined.
Existing tools were individual and mainly competitive, not relational or supportive.
ANALYSING OUR INSIGHTS
THE SOLUTION
Using connection to support healthy habits and relationships
Kintra transforms health tracking into a shared journey.
By combining step, water, and mood tracking with subtle emotional feedback, couples can set goals together, check in on each other’s progress, and celebrate small wins as a team.
The experience focuses on progress over perfection, building consistent routines through empathy, not pressure.
Design approach
We mapped our user insights into key design principles:
Mutual motivation:
both partners contribute to progress, and interact to support eachother.
Emotional visibility:
each user can see and respond to the other’s mood.
Ease of use:
quick daily inputs designed for time-poor office workers.
Through rapid prototyping and testing in Figma, we refined the interaction flow around micro-moments of connection with small gestures that make users feel seen and supported.
Interaction & Motion
Kintra’s interface is designed for clarity, consistency, and ease of use.
Motion is used purposefully to guide attention, show progress, and provide feedback, helping users stay engaged and feel connected.
Animations highlight shared achievements between partners, reinforcing motivation and making health tracking feel intuitive and rewarding.
GROWTH & SCALABILITY
Positioning & Future Potential
By reframing wellness as a relationship-driven experience, Kintra fills a gap in the saturated health-tracking market. It creates a unique environment where progress is prioritised over perfection.
The concept naturally integrates with Apple Health and Apple Watch, creating potential for cross-platform growth, retention through shared goals, and expansion into friend or family networks.
FEEDBACK + OUTCOME
After pitching Kintra twice to external designers and an Apple software engineer, we received encouraging feedback and outcomes:
Finalist in the Australian Graphic Design Awards (AGDA) 2025 - Student Digital Category
Quotes from the Panel
"Your solution creates something really meaningful that the market is missing, I haven't seen a couples app like this before. It's clear that your team's solution was properly thought out to solve a problem through user experience."
"The UI is beautiful, the elements of motion make the app engaging and create this feeling of connection and satisfaction"
The Project received the highest score out of the 10 teams pitching in the
Apple Foundation Program unit.
Reflection
Leading the UX process for Kintra taught me how to translate empathy into practical, strategic design.
Being able to use insights from real users and analyse them to solve a problem was really meaningful to me, and strengthened my analysis and leadership skills.
It also made me passionate about human-centred design and how thoughtful digital experiences can genuinely improve people’s lives.
This project reminded me that the best products always put the user first. No problem can be solved without human insight, the best solutions come from deep understanding.
