After you’ve applied a FreeStyle Libre sensor to the back of your upper arm, open the app and hold the back of your Android phone near (exact distance will vary by phone) the FreeStyle Libre sensor to scan it. The size and location of the NFC antenna in Android phones varies by make and model, so you may have to move the phone around to find the best position for scanning the FreeStyle Libre sensor.

Once you have found the optimal scan position, wait for the app to produce two distinct tones or vibrations before you move the phone away from the FreeStyle Libre sensor. The first tone indicates the phone’s NFC has recognized the sensor. The second tone indicates the scan is complete.


After you’ve applied a FreeStyle Libre sensor to the back of your upper arm, open the app and tap one of the scan buttons within the app to put the iPhone in a scan ready state. There are two types of scan buttons – a blue button on the Home screen and a gray scan icon in the top right corner of most screens. Hold the top edge of your iPhone near the sensor and do not move your iPhone until you hear a tone and/or feel a vibration, which indicates the scan is complete.



What is the FreeStyle LibreLink mobile app?

The FreeStyle LibreLink app is a mobile app designed to work with FreeStyle Libre sensors. The app enables you to monitor your glucose using your iPhone or Android phone1 with a FreeStyle Libre sensor — there is no need to use a separate blood glucose meter for routine glucose monitoring.2 When you scan the sensor with a compatible phone that’s running the FreeStyle LibreLink app, your glucose data is displayed directly on that device.


With the app you can:

  • View your current glucose reading, a trend arrow, which indicates how your glucose is changing, and the last 8-hours of glucose history
  • See glucose reports, including your Ambulatory Glucose Profile, which reveal trends and patterns
  • Add notes to track your food, insulin use, exercise, and other events
  • Connect to healthcare professionals and caregivers with LibreView and LibreLinkUp3


To use the FreeStyle LibreLink app, you must register with LibreView, a cloud-based diabetes management system provided by Abbott and Newyu, Inc. Please see the product labeling for FreeStyle Libre and the FreeStyle LibreLink app for specific instructions on using the different products, including the supported age range.


Important: You must have a compatible iPhone or Android phone to install and use the app (See Compatibility Guide).


1The FreeStyle LibreLink app is compatible with NFC enabled phones running Android OS 5.0 or higher and with iPhone 7 and higher running OS 11 and higher.

2The FreeStyle LibreLink app and the FreeStyle Libre reader have similar but not identical features. A finger prick test using a blood glucose meter is required during times of rapidly changing glucose levels when interstitial fluid glucose levels may not accurately reflect blood glucose levels or if hypoglycaemia or impending hypoglycaemia is reported by the Sensor or when symptoms do not match the Sensor readings.

3LibreLinkUp is a mobile application, developed and provided by Newyu.


There is an update available for the FreeStyle LibreLink app (version 2.2.1). Users can visit Google Play to install the latest update of the app (version 2.2.2).
