Support for your FreeStyle Libre 2 system

We’re aware of the iOS 18 release by Apple and plan to update the Compatibility Guide as soon as iOS 18 is verified for compatibility with our apps. We always recommend checking the Compatibility Guide before updating your phone’s operating system.

If you are using an operating system or phone that is not listed on the Compatibility Guide, it’s important to note that some functionality such as glucose alarms¹ and data sharing² may not work on phones or operating systems that have not been evaluated or have been deemed incompatible.

We recommend displaying automatic operating system updates on your mobile device.

Please visit our User Manuals page for future Compatibility Guide updates.
 

1. Notifications will only be received when alarms are turned on and the sensor is within range of the reading device. You must enable the appropriate settings on your smartphone to receive alarms and alerts, see the FreeStyle LibreLink or FreeStyle Libre 3 User’s Manual for more information.

2. The user’s device must have internet connectivity for glucose data to automatically upload to LibreView and to transfer to connected LibreLinkUp app users.

We are regularly evaluating and verifying compatibility with newer operating system versions with the FreeStyle LibreLink^◊ and FreeStyle Libre 3^◊◊ apps.

When a new operating system has been released by Android or Apple, our teams work as quickly as possible to verify and confirm compatibility.

Once a new operating system version is verified to be compatible, it will be published in our Compatibility Guides. Please check the Compatibility Guide before installing a new operating system version on your smartphone.
 

◊ The FreeStyle LibreLink app is only compatible with certain mobile devices and operating systems. Please check our website for more information about device compatibility before using the app. Sharing of glucose data requires registration with LibreView.

Yes. There is one new feature being introduced with iOS 18 that will impact your ability to use the FreeStyle LibreLink^◊ and FreeStyle Libre 3^◊◊ apps.

New iOS 18 features:

• Locked and hidden apps

◊ The FreeStyle LibreLink app is only compatible with certain mobile devices and operating systems. Please check our website for more information about device compatibility before using the app. Sharing of glucose data requires registration with LibreView.

◊◊ The FreeStyle Libre 3 app is only compatible with certain mobile devices and operating systems. Please check our website for more information about device compatibility before using the app. Sharing of glucose data requires registration with LibreView.

These features are enabled OFF by default.

Locked and hidden apps offer users peace of mind that information they want to keep private, such as app notifications and content, will not inadvertently be seen by others. Users can now lock an app; and for additional privacy, they can hide an app, moving it to a locked, hidden apps folder.

When an app is locked or hidden, content like messages or email inside the app are hidden from searches, notifications, and other places across the system.

If you use the Locked and Hidden app feature with the FreeStyle LibreLink^◊ or FreeStyle Libre 3 app^◊◊, you risk missing system and glucose alarm¹ notifications from the FreeStyle LibreLink^◊ or FreeStyle Libre 3 app^◊◊.

1. Notifications will only be received when alarms are turned on and the sensor is within range of the reading device. You must enable the appropriate settings on your smartphone to receive alarms and alerts, see the FreeStyle LibreLink or FreeStyle Libre 3 User’s Manual for more information.
