Compatible Phones for Freestyle Libre 2

Understanding Freestyle Libre 2 Compatibility

The Freestyle Libre 2 system monitors blood sugar levels without finger pricks. It uses a small sensor worn on the back of the upper arm. This sensor sends real-time glucose readings to a compatible smartphone or reader. Alarms alert users when glucose levels are too high or low. The system also stores data, helping users track trends over time.

Device Requirements for Freestyle Libre 2

To use the Freestyle Libre 2, your phone needs to meet specific requirements. First, it must run on iOS 13.2 or later if you have an iPhone. For Android users, your device should operate on Android 8.0 or higher. Additionally, your phone must support Near Field Communication (NFC).

Check if your phone has Bluetooth 4.0 or later because the Libre 2 uses Bluetooth for real-time glucose readings. Ensure your device has enough storage space for the app, which requires about 100 MB.

Popular compatible iPhones include the iPhone 6s, iPhone 7, iPhone 8, iPhone X, and newer models. For Android, phones like the Samsung Galaxy S8, S9, S10, Google Pixel 2, Pixel 3, and newer models work well.

Make sure your phone’s operating system is up-to-date. Older versions might not support the app, causing issues. Also, ensure your phone’s battery is in good condition. The app runs continuously, so a weak battery might drain quickly.

Lastly, check if your phone is unlocked. Some carrier-locked phones might have restrictions that could interfere with the app’s functionality. If your phone meets these criteria, you’re good to go!
