Glooko
Round-over-round moderated usability testing of Glooko's Type 2 Diabetes management app — evaluating whether people living with diabetes could read the data displays, navigate the app, and feel confident managing their condition.

What we walked into.
Glooko was designing a mobile app to help people with Type 2 Diabetes manage their condition — data displays, trends, and graphs that had to be genuinely legible and actionable for patients on injected insulin. The team needed to know, round over round, whether real users understood the information and felt confident acting on it.
How we worked.
- Moderated Usability Testing
- Prototype Evaluation
- Iterative Research Rounds
- Patient Participant Recruiting
- Findings & Design Recommendations
Naviscent ran moderated usability sessions with participants living with Type 2 Diabetes, testing a mid-fidelity prototype that simulated the phone app. As a later round in an iterative program, the study deliberately revisited the home page, trends, graphs, and navigation so the team could compare against earlier results and see whether design changes were landing. Patients were recruited to a tight clinical profile and run through structured, task-based sessions.
What we delivered.
Each round gave Glooko's design team direct evidence of where the app was working for patients and where it still needed to change — feeding an iterative loop that kept design decisions grounded in how people actually living with diabetes read and act on their data.
Round over round, one test: can someone managing diabetes actually read this screen and act on it with confidence?
