The FreeStyle Libre system measures glucose levels through a small sensor — the size of two stacked quarters- applied to the back of your upper arm. It provides real-time glucose readings for up to 10 days, both day and night. The sensor can also read glucose levels through clothes, making testing discreet and convenient. The data generated by the FreeStyle Libre system is designed to provide actionable trends and patterns that help you make better decisions about your health, such as adjustments to your diet or how much insulin you need to take.

The project was led by John White while at Insight Product Development.
