Dangpro is a digital healthcare app built with Daesang, Korea’s leading food and wellness company. As the founding product designer, I led the product from scratch - shaping the system logic, UX flows, and design strategy. The challenge: rebuild diabetes care from fragmented tracking into a closed loop of data, action, reward, and family support.
Within months, the app reached 100,000+ downloads, positioning Daesang not just as a food company, but as a digital health innovator.

Managing diabetes has become a daily habit, yet most people still do it alone.
Diabetes is no longer a rare condition, it’s part of everyday life. Nearly 1 in 6 adults live with diabetes, and many more are at risk. Managing it means endless micro-decisions: what to eat, how much to walk, when to measure, when to rest. Despite this constant effort, most people still manage on their own — without continuous feedback, connection, or support.
Diabetes management today is more about persistence than connection.
Every stakeholder was trying, doctors guided, patients logged, families cared, and companies promoted. But without a shared system to connect their actions, effort stayed isolated and progress never looped back.
Doctors
Patients
Logged glucose, meals, and exercise every day, but the numbers never turned into insight or motivation.
Families
Tried to support with care and reminders, but without visibility, their support turned into quiet worry.
Everyone was doing something right but without a system to connect their actions, every effort faded into isolation.
This app was built to close the loop, transforming daily effort into connected, meaningful care.
As the founding product designer, I reframed the product’s goal: from simply recording numbers to driving real behavior change. The design centered around one idea — every effort a patient makes should return as insight, motivation, or tangible value.
We first approached it as an app, when what we needed was a system.
When I joined, the team was focused on building a better blood sugar logging app, more charts, more logs, more features. But none of it answered a simple question: what actually happens after data is recorded? The early design focused on input, not interpretation, collecting numbers without turning them into meaning or action.
Early prototypes focused on logging, not learning,recording effort without translating it into action.
But during user interviews, patients kept repeating the same thing:
Geunmyeong Park
Type 2 diabetes patient
“Doctors tell me what I should do, but no one shows me how to fit it into my life.”
Jaeyeol Lee
Type 1 diabetes patient
Moment of realization
When I mapped the patient’s real routine, I realized the problem wasn’t inactivity - it was fragmentation. Patients, families, doctors, and companies were all doing their part, yet none of their actions talked to each other. Every effort moved in parallel, disconnected from a shared loop of insight, feedback, or reinforcement
Rebuilding the system together, co-designing a sustainable care loop with every stakeholder.
The old system trapped each stakeholder in isolation — patients logged, families worried, and doctors advised, but none of it connected. To rebuild the loop, I co-designed the experience with each group, translating their constraints into actionable design principles that make the system sustainable in real use.
We rebuilt the system so every actor’s effort now feeds into one continuous care loop.
The redesigned loop connects all key stakeholders — patients, doctors, families, and the company - through real-time data, feedback, and shared motivation. Each small milestone, like logging glucose, receiving insight, or offering encouragement, now triggers the next step in the cycle. What used to be separate actions now work together as a living, self-sustaining system
Each feature was designed not as a tool, but as a moment, seamlessly woven into a patient’s daily rhythm.
Mr. Park logs his blood sugar on paper every day,
but he never knows what’s normal or risky.
No feedback, no motivation, just numbers on a page.
Now, he can record smarter, not just more.
Mr. Park logs his blood sugar before and after meals,
and the app instantly tells him if his level is stable or needs care.
Each record earns 100 points, turning a routine task into steady motivation.
