FreeStyle Libre 2, Now Connected to Your iPhone
Diabetes Care | Aug. 25, 2021

In the spirit of keeping you apprised of the latest updates to our diabetes monitoring apparatus — you know, the FreeStyle Libre 2, an integrated continuous glucose monitoring (iCGM) system — we bring news of Food and Drug Administration clearance of our FreeStyle Libre 2 app for iPhone users to connect their compatible smartphones to their FreeStyle Libre 2 sensors.

We understand the appeal to connected care and the rapport many have with their smart devices. We appreciate the readily apparent need for these kinds of applications of technology to daily lives. Whatever apprehensiveness there might have been before, one important outcome of the COVID-19 pandemic has been a near insatiable appetite for more reliable digital and connected diabetes care.

And that's just what the FreeStyle Libre 2 iOS app brings.

Simply apply the sensor to the back of your upper arm and with your iOS app, scan the sensor to get your latest glucose levels, including a trend arrow and 8-hour historical graph showing how your glucose is reacting to food, exercise and more.

For those still checking their glucose with routine fingersticks,1 it's hard to fathom how FreeStyle Libre technology could disappoint.

With its small sensor size — its appearance likely to go unnoticed — FreeStyle Libre 2 iOS app users can discreetly2 check their glucose with a quick, 1-second scan of their compatible iPhone over their sensor. It's as essential as it is inconspicuous.

Ever since FreeStyle Libre's initial launch, we have grappled with how to make the world's leading glucose monitoring system3 — an appellation we do not take for granted — even better.

It's not by happenstance.

These developments have included longer wear times up to 14 days for each sensor, optional alarms,4 unsurpassed 14-day accuracy5 as well as FreeStyle LibreLink6 and Libre LinkUp7 apps to help those caring for people managing their diabetes to know what's happening. It's a better appliance for a modern world that we're working hard to continually improve, from FreeStyle Libre 14 day to FreeStyle Libre 2 to FreeStyle Libre 3,8 which initial users are raving about.

Approximately 3.5 million users around the world count on the FreeStyle Libre system to help them manage their diabetes. We think you'd find it appealing for all the same reasons they do, with all of its technological trappings, which now include an iOS app for FreeStyle Libre 2 users in the U.S.

(Notice all those words with "app" in them? Just our helpful reminder FreeStyle Libre 2 measures your glucose data every minute for up to 14 days, so you always have the most recent information available via an app on your compatible iOS smartphone.)
