The FreeStyle LibreLink app is a mobile application designed to work with FreeStyle Libre sensors. The app enables you to monitor your glucose using your iPhone* with a FreeStyle Libre sensor – there is no need to use a separate blood glucose meter for routine glucose monitoring.† When you scan the sensor with a compatible iPhone that’s running the FreeStyle LibreLink app, your glucose data is displayed directly on your phone.
With the app, you can:
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 labelling for the FreeStyle Libre system 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 to install and use the app. See Compatibility Guide
The app is designed to work with iPhones that meet the following minimum requirements. You can also check the Compatibility Guide for additional information.
Yes, the FreeStyle LibreLink app holds a medical device license in Canada, number 99351, and is downloadable at no charge.
No, the FreeStyle LibreLink app is the only app that has been tested by Abbott to be compatible with FreeStyle Libre sensors. The FreeStyle LibreLink app‡‡ was developed to ensure compliance with local regulations, including safety and performance requirements in accordance with the intended use. Any product that is intended to be compatible with FreeStyle Libre sensors would also need to comply with these regulations.
NFC is the wireless communication technology that enables your FreeStyle Libre sensor to wirelessly transmit data to another device.
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.
The app has the same indications for use as the FreeStyle Libre system. The FreeStyle Libre flash glucose monitoring system is indicated for measuring interstitial fluid glucose levels in adults aged 18 years and older who have at least 2 years of experience in self-managing their diabetes. For In Vitro Diagnostic Use Only. Always read and follow the label/insert for detailed instructions and indication of use.
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 grey 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.
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 Near-field Communication (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.
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.
There’s no need to use a separate glucose meter for routine testing.† 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 hypoglycemia or impending hypoglycemia is reported by the sensor, or when symptoms do not match the sensor readings.
You can choose to monitor your glucose levels with either the app, the reader, or both.** 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 within one hour.
Remember that the FreeStyle LibreLink app and FreeStyle Libre reader 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 8 hours so you and your healthcare professional can get a complete picture of your glucose trends and patterns.
No. 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.
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.
Yes. 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. Do not scan your sensor if restricted by flight regulations.
WiFi 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 healthcare team or with other connected apps. The app does not require a WiFi or 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 WiFi or mobile data connection is restored.
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.
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.
No. The FreeStyle LibreLink app is not supported on jailbroken iPhones.

The app will display a clock icon on the glucose graph to indicate when there has been a time change. It is necessary to use the correct time for accurate reports. If your phone’s time is not set to update automatically, you will need to update your phone’s time settings in order to continue using the app.
The app includes a series of reports that highlight your glucose trends and patterns. From the main menu, select the report you wish to see.
A minimum of 5 days of sensor data is required for an estimated A1C to be calculated.
Email or text reports directly from the app by tapping the share icon that’s displayed at the bottom of each report available within the app. You can also show the reports on your phone to your doctor or nurse during your next appointment. LibreView may also be an option if your doctor has set it up for patients to share data. See next FAQ.
