Accu-Chek 360 Diabetes Management App: Building a clear vocabulary for an FDA-regulated product

Accu-Chek 360 is a diabetes management app built for Roche Diagnostics. Unlike many diabetes trackers, it falls under FDA medical device classification as it can tell the user how much insulin to inject.

An early part of the design process for AC360 was a seminar with a DNE (diabetes nurse educator) at the Roche campus. We were given the full introduction that a newly-diagnosed patient would undergo, learning how insulin and glucose levels work together, and how regular blood testing and bolus injection are used to maintain the balance that the pancreas would otherwise provide.

I worked with our team’s UX lead to construct a UI system that would tie together a log of blood glucose measurements and bolus injections with an advisor component that would recommend an injection amount, and a reporting system that would allow patients to analyze their diabetes management over longer periods. The advisor posed a specific challenge both in visually explaining the calculation that led to the recommendation, and in working with engineering to implement the visualization.
