Mobile and Browser application, for cardiovascular diseases prevention

Application that helps for people to track their heart rate, health condition, and live healthier life.

Role: User Research, UX/UI Design, Design systems

Discovery and defintion

It’s challenging for older adults to easily monitor their health. With a high percentage of people affected by cardiovascular diseases, the market is substantial. The idea was to create an app that helps users track their habits and heart rate, in combination with a physical product (heart rate monitor), to identify potential problems.

Problem

While working at Cardi.Health, my primary focus was on enhancing the iOS and browser-based apps, which were highly popular among our users.

Cardi initially started as a simple tracker for BPM, HR, and meal logging, making it easy for users to monitor their heart health and prevent cardiovascular diseases. As the platform grew, the goal was not only to attract more users but also to make Cardi part of their daily routine. New features were added, such as a physical BPM device, personalized meal plans, and a medication tracker.

However, we faced a challenge: users were not sufficiently engaged, leading to low activity metrics. That’s when I began my research on how to improve user engagement.

User Research

When working on a design project, it’s crucial to support your identified problems with data. In this case, we had clear metrics showing that 50% of subscribed users logged in once a week or even less. We dedicated time to understanding the reasons behind this low engagement and studied all the data we had available. In addition, we conducted user interviews and consulted with cardiologists about real-life cases that could be relevant to patients and increase their involvement.

We also carried out a real-life study with university students and seniors, providing them with the app and a device, and asking them to use it for a month while giving us feedback. After gathering insights, comments, and testimonials from actual users, we made the decision to provide personalized data and analytics based on the information users shared with us. This is how the idea for the “Insights” page was born.

Insights page

Adding the Insights page offered several advantages. Firstly, it provided users with personalized data tailored to them, allowing us to highlight trends in their health, identify any instabilities, and offer tips to promote stability. Secondly, we introduced the ‘Stories’ feature, which included articles about heart health and ways to improve it, as well as important practices to consider.

This new page increased our metrics by 25% and demonstrated that it was genuinely needed by our users. They now had a platform not only to log their measurements but also to track changes and work on improvements.

My Role & Overall input in Cardi.Health

When I joined the team, the MVP version was already completed. My first task was to develop a desktop/browser-based application, considering our target audience’s higher age and the fact that not all users had smartphones. A design system had been created prior to my arrival, but I improved and restructured it by creating new atoms, molecules, and components.

I implemented various features, including the Insights page, where users could track their improvements and receive health tips, as well as the introduction of a ‘Stories’ function. For each feature, I collaborated with a Lithuanian cardiologist, conducted user interviews, and launched unmonitored user tests to better understand user needs. Extensive prototyping and wireframing were done for specific feature tests to ensure the application was presented in its best version.

I've worked with.

The website builder allows users with minimal technical skills to quickly create websites or online stores, including payment and inventory tools for small businesses.

The online booking management system for all service-based businesses. The system helps easier to track & manage each reservation, with better UX for clients to book the service they need.
