Description
Quick answer: This is a pack of two FreeStyle Libre 3 Plus sensors — Abbott’s smallest, thinnest sensor, with a 15-day wear time each. Together they provide about one month (up to 30 days) of continuous glucose monitoring. Unlike scan-based systems, the Libre 3 Plus automatically streams real-time glucose readings to your phone or reader every minute — no scanning and no fingersticks. It supports integration with compatible insulin pumps. You’ll need a display device (the FreeStyle Libre 3 app on a compatible smartphone, or the FreeStyle Libre 3 reader), sold separately. A prescription is required. For ages 2 and up.
What’s in this pack?
Two FreeStyle Libre 3 Plus sensors. Each is the world’s smallest and thinnest sensor — smaller than two stacked pennies — with up to 15-day accuracy and minute-to-minute glucose readings. Because each lasts 15 days, a 2-pack covers roughly one month — a convenient resupply quantity. The sensor provides customizable alerts and alarms, sends a new glucose reading every minute, and connects with automated insulin delivery (AID) systems.

Is it compatible with my setup?
The Libre 3 Plus sensor requires a FreeStyle Libre 3 display device — either the FreeStyle Libre 3 app on a compatible smartphone, or the FreeStyle Libre 3 reader. It uses the same app as the Libre 3, and you must have a Libre 3 reader or a compatible smartphone to receive the readings. It is not read by the FreeStyle Libre 2 reader. The Libre 3 Plus also supports integration with compatible insulin pumps / AID systems.
