Check Blood Sugar With Phone: How CGM Replaced the Finger Prick
Ten years ago, checking glucose meant a lancet, a strip, and a drop of blood every single time. Today you can check blood sugar with phone in seconds, with no needle involved after the initial sensor placement. Here is how the technology behind that shift actually works, and what it takes to set it up for yourself.
What Is Freestyle Libre 3 Plus in This Picture
What is freestyle libre 3 plus, specifically, is one of the leading cgm device options built for phone based reading. It pairs directly with iOS and Android, sends glucose data every minute, and holds a freestyle libre 15 day wear time, one day longer than the standard Libre 3, before the sensor needs replacing.
Setting Up Your Phone to Read Glucose
The Freestyle Libre 3 Plus setup guide process is short. Download the manufacturer app, apply the libre 3 plus sensor to the back of your upper arm, and pair it through Bluetooth. A one hour warm up period follows before your phone starts displaying live numbers. From that point, your glucose monitor readings update automatically in the background without you opening the app each time.
