How Do You Apply and Use the FreeStyle Libre 3 Plus Sensor?
Follow these steps to apply your sensor correctly:
- Take an alcohol wipe and clean the area where you plan to apply the sensor.
- Remove the sensor from its packaging and peel off the backing.
- Press the applicator firmly against your skin until you hear a click; the sensor inserts automatically.
- Press the start button on the sensor to begin your session.
- Wait 60 minutes for the warm-up period before your first reading appears.
- Open the FreeStyle Libre 3 app on your phone; readings will appear automatically every minute.
Tip: Always read the full user manual before your first use. If the sensor loosens during wear, use a CGM patch to keep it firmly adhered to your skin.
Which Apps & Devices Are Compatible With FreeStyle Libre 3 Plus?
The FreeStyle Libre 3 Plus Sensor works seamlessly with the FreeStyle Libre 3 app, available for:

The app automatically receives glucose readings every minute via Bluetooth (up to 33 feet range, unobstructed). You can view real-time glucose values, trend graphs, and historical data, and share readings with up to 20 care partners through the LibreLinkUp companion app, or with your healthcare provider via LibreView.
Common FreeStyle Libre 3 Plus Issues & Prevention
- Side sleepers: Avoid placing the sensor on the side you normally sleep on to prevent false low readings at night.
- Sensor adhesion: If your sensor loosens prematurely, consider using a CGM adhesive patch to keep it securely in place, available on the CGM Patches page at CGM Monitors.
- Readings don’t match symptoms: If your sensor reading doesn’t match how you feel, perform a fingerstick blood glucose test to confirm. Always follow your doctor’s guidance for treatment decisions.
- High Vitamin C intake: High levels of Vitamin C can affect sensor accuracy. Check the user manual for details.
- MRI scans: Wait 1 hour after an MRI before relying on sensor readings. CT scans and X-rays do not affect sensor performance.
Important: You can use your existing Freestyle Libre 3 reader with these sensors. Or, simply download the Libre app on your phone and use it as a reader.
