Zest Activity Tracker
My role:
Product Designer
Zest is a platform that helps people living with diabetes achieve reversal using holistic methods. One of which includes activity recommendation and management currently that happens via pdfs and conversations with caregivers. This project was to integrate an activity recommendation and log system in the platform.
What was done
For the Zest Activity Tracker project, I designed a comprehensive activity recommendation and logging system to be integrated into the Platos Health platform. This involved end‑to‑end UX and UI work, including research, wireframing, high‑fidelity design, prototyping, and hand‑off documentation.
I led the design sprint with a cross‑functional team of designers, developers, and a marketing expert to define the experience from scratch and translate complex health needs into an intuitive user interface.
Why was it done
The goal of the project was to enhance the existing Platos Health platform by embedding activity tracking functionality that supports adults living with type 2 diabetes. Regular physical activity is critical for improving insulin action and overall metabolic health, yet many patients struggle to stay consistent or to document their progress with caregivers. The activity tracker aimed to provide a digital tool that would help users log and manage their exercise, receive tailored recommendations, and make progress visible and actionable within their care plan.
How was it done
Design began with a research phase, where I conducted secondary research on physical activity guidelines and user needs. I then ran a focused design sprint with two other product designers, one developer, and one marketing expert to unpack problems and generate solution concepts collaboratively.
Sketches and early flows were iterated quickly to explore information architecture and core interactions. These sketches were then translated into digital wireframes and refined into high‑fidelity prototypes using the company’s design system to maintain visual and interaction consistency. The final designs were prepared for developer hand‑off with annotated screens and a prototype that demonstrated key journeys.
Although the first iteration was delivered to engineering, the project remains in progress with plans for expanded features like activity review, educational content, and gamification to further boost engagement.
Conclusion
This project was done to expand the offering of the current product and is still a work in progress. Although the first iteration has been handed off to the development team, other features like an activity review system, learning material to help users understand benefit of an activity, and gamification to ensure enjoyability are all on the horizon
