Quick Timeout for Time in Range
Let's get a basic TIR foundation:

• TIR captures time a person spends in their target glucose range, often shown as a bar graph.
• That range is 70 (hypoglycemia) to 180 mg/dL (hyperglycemia) for most people.
• The target window to be in range is about 17 hours each day, or 70 percent.
• Where A1C measures of your average blood sugar over three months, it can't show users daily highs and lows the way CGMs can. Seeing how food choices, exercise and more in real-time impact your body can help you stay in range longer and more often, particularly for those using an app with their FreeStyle Libre system.

And now, let's look at that data in The Journal of Diabetes Science and Technology. It showed that people using FreeStyle LibreLink app (versus a reader) experienced an average of 1.2 hours — or 5% — more in range.²

We Have an App for That
Our Apple iPhone app was recently cleared by the Food and Drug Administration to connect compatible smartphones to your FreeStyle Libre 2 sensors to capture glucose readings from the small sensor worn on the back of your upper arm directly to your compatible phone.

This app adds on to our already available digital portfolio which includes FreeStyle LibreLink³ and Libre LinkUp⁴ apps to help those caring for people managing their diabetes to know what's happening.

Taken together, they represent a silver lining in the cloud of COVID-19 that quickly accelerated demand for more reliable affordable and accessible.⁵

"Time in Range is a critical metric for diabetes management because it gives that immediate visibility into glucose levels, and it is possible to measure now that we have FreeStyle Libre technology and digital health tools," said Mahmood Kazemi, M.D., divisional vice president, global medical and scientific affairs and chief medical officer, Diabetes Care, Abbott. "This technology helps people living with diabetes make lifestyle choices that are personalized to their own target data."

Simply, as the American Diabetes Association says, "The more time you spend in range, the less likely you are to develop certain diabetes complications."

That's the time you want, in the range you want it.

How sweet it is.
