What is the FreeStyle LibreLink mobile app?
The FreeStyle LibreLink app is a mobile medical app designed to work with FreeStyle Libre sensors. The app enables you to monitor your glucose using your iPhone or Android phone9 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 LibreLinkUp13
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).
9 The FreeStyle LibreLink app is compatible with NFC enabled phones running Android OS 5.0 or higher and with iPhone 7 and OS 11 and higher.
2 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 system or when symptoms do not match the system readings.
13LibreLinkUp is compatible with Android phone running Android OS 4.4 and higher and iPhones running iOS 10 and higher.

22 Use of the FreeStyle LibreLink app requires registration with LibreView, a service provided by Abbott and Newyu, Inc.
What is near-field communication (NFC) and how do I know if my phone has it?
NFC is the wireless communication technology that enables your FreeStyle Libre sensors to wirelessly transmit data to another device.
For Android users: Your Android phone must have NFC capabilities and NFC must be enabled. Many of the latest Android phones support NFC. Check your phone's manual or go to the phone’s Settings menu and look for settings related to ‘NFC’, ‘Connections’, ‘Sharing’, or ‘Wireless & Networks.’
For iPhone users: You must have an iPhone 7 or higher running iOS 11 or higher to utilize the NFC capability needed to scan the FreeStyle Libre sensor.
Is the app approved for pediatric use or pregnant women?
The app has the same indications for use as the FreeStyle Libre system. Please see the FreeStyle Libre system indications for use for your country.
How do I scan my FreeStyle Libre sensor with my phone?
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.
Do I have to remove the case on my phone to scan the sensor?
You may or may not have to remove your phone case – it depends on the material that the case is made from, how thick the case is, and how well your phone’s NFC antenna works. If your phone case is made from plastic or silicone or another non-conductive material, you will probably be able to scan the sensor without removing the case. If the case is aluminum, metal or anything else that has a conductive surface, you may need to remove the case before scanning your sensor. The thickness of the case can also make a difference. If your case is very thick, it could prevent the phone from scanning the sensor.
Can the app replace my FreeStyle Libre reader?
Yes. The app was developed using the same technology that is in the FreeStyle Libre reader for receiving and processing glucose data, so it can also be used for routine glucose monitoring. The app can be used instead of or in combination with the FreeStyle Libre reader.
Do I need to carry a separate blood glucose meter?
There’s no need to use a separate blood glucose meter for routine testing.2 The app allows you to get glucose results as often as you like by simply scanning your FreeStyle Libre sensor with your phone.
However, 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, if hypoglycaemia or impending hypoglycaemia is reported by the Sensor, or when symptoms do not match the Sensor readings.
2A 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 system or when symptoms do not match the system readings.
Can I use my FreeStyle Libre reader and FreeStyle LibreLink app with the same sensor?
You can choose to monitor your glucose levels with either the app, the reader, or both11. You can use the FreeStyle LibreLink app and the FreeStyle Libre reader with the same sensor, as long as you start the sensor with the reader first, and then scan the newly started sensor with your phone.
Remember that the FreeStyle LibreLink app and FreeStyle Libre readers do not share data with each other. For example, if you switch between your reader and the app, you may see gaps in your glucose data, which will affect the reports available through the reader, the FreeStyle LibreLink app, and LibreView. It is important to continue scanning your sensor with either the app or the reader at least once every eight hours so you and your healthcare professional can get a complete picture of your glucose trends and patterns.
11The 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 LibreLink app or when symptoms do not match the FreeStyle LibreLink app readings.
Can I use the FreeStyle LibreLink app to scan someone else’s sensor?
The FreeStyle LibreLink app is intended to be used with only one sensor (and one person) at a time. Each app account is associated with one person. However, people who use the FreeStyle LibreLink app can connect with their caregivers if they are using a separate app called LibreLinkUp. LibreLinkUp allows caregivers to remotely monitor glucose readings performed by their love ones.
Can the FreeStyle LibreLink app be used to make insulin dosing decisions?
Yes. People with diabetes can use FreeStyle Libre sensors with the app to better understand the impact of actions like eating, exercise, and taking insulin based on their glucose levels. They can also make day-to-day therapy decisions when using the app with a FreeStyle Libre sensor, including insulin dosing decisions, based on guidance from their healthcare professional.
Will the FreeStyle LibreLink app work in ‘airplane mode’?
Yes. If you use an Android phone, you may need to go to your phone’s settings and reactivate NFC when your phone is in airplane mode. You can scan with your iPhone in airplane mode by tapping one of the scan buttons in the app to put it in a scan ready state.
What if I don’t have phone service or Wi-Fi?
Wi-Fi or a mobile data connection are only required for initial app setup (downloading / installing the app, creating an account, or signing in) and sharing your glucose information with your care team or with other connected apps. The app does not require a Wi-Fi or a mobile data connection to scan your sensor or to record your current glucose readings. During periods when your phone is operating in a disconnected state, your data will only be uploaded to LibreView after a Wi-Fi or mobile data connection is restored.
Does the FreeStyle LibreLink app cause my phone battery to deplete more quickly?
No, the FreeStyle LibreLink app is meant to be used as often as you like and should not have a noticeable effect on battery life beyond your normal usage patterns.
What happens if my phone battery dies?
If your phone battery dies, charge your phone to continue using the FreeStyle LibreLink app. Your data will not be lost if the phone battery dies and you can scan the sensor while the phone is being charged.
