Overview
Biolink Health is a mobile app designed to support people with type 2 diabetes in managing their condition. It offers a range of features including food and activity tracking, blood glucose logging, educational content, personalised tips, and access to expert consultations — all aimed at building healthy, sustainable habits.
Challenge
In 2018, Biolink.Tech began working on a wearable device capable of continuously tracking blood glucose levels. My task was to create a mobile app that would act as the interface between the user and the device — helping people interpret the data, stay motivated, and take small, consistent actions every day.
The challenge was to keep the experience simple and focused, even as the app brought together multiple data streams and behavioural nudges.
Results
As the sole designer on the project, I was responsible for both UX research and UI design, starting entirely from scratch — with no existing layouts, UI components, or a design system.Working closely with a product manager, I conducted in-depth interviews with English-speaking users and built the app’s structure alongside a reusable component library. Over six months, we delivered a fully functional MVP ready for user testing, which showed strong results across key product metrics:
82 SUS
indicating a strong, well-received MVP experience
3–4
taps to log a full entry vs 6–8 taps in other diabetes trackers
93%
success rate — 14 of 15 users completed key flows without help
Design
Although the app was intended to work with Biolink’s wearable device for automatic glucose tracking, we also needed to support manual data entry. This ensured that users could still rely on the app independently.
The interface prioritises clarity and speed: entry flows are optimised for minimal effort. Beyond simplifying data input, the app’s navigation structure was designed to help users see the bigger picture — how their daily habits, including eating patterns and physical activity, directly influence glucose levels.
Interface overview
Summary page
After login, the Summary page is the user’s first touchpoint. The top section serves two key purposes: educating users with fresh Biolink media materials about diabetes (in a Stories format) and displaying the latest blood sugar level.
Daily goals and trends
The Summary page also includes a quick overview of daily diabetes management goals — a core product value designed to support behavior change and improve well-being through habits that directly impact type 2 diabetes management. The glucose trend card provides short, in-card text hints that help users understand where their health is heading over time.
Actions hub
People with diabetes regularly track multiple data points. To make this easier, I designed a bottom navigation hub that lets users log data in just 3–4 taps.
To-dos
These recommendations provide actionable steps people can take when their readings are abnormal, supporting proactive management of their condition. To support informed health decisions, we introduced personalised recommendations — ‘to-dos’ — tailored to user data.
Reports
The Reports section provides an overview of key health metrics. Graphs for blood glucose, meals, and activity are placed together on one page, enabling users to spot patterns and understand how diet and exercise affect sugar levels. It lets them anticipate spikes and build healthier habits.
Report details
Tapping on a report card reveals the detailed log history for that specific report. This allows focusing on a particular metric and easily sharing relevant data with a physician.
Timeline
Observing blood sugar, medication, food, and exercise in a chronological timeline is essential for effective diabetes management. This view guides people in understanding how their lifestyle affects their body.
Chat
In addition to health-related topics, users can also contact support directly within the chat to resolve any issues they encounter. The app’s chat feature provides personalised guidance for newly diagnosed individuals, helping them respond to health changes and take timely action.

Despite these challenges, we successfully delivered an MVP.
