No, the FreeStyle Libre system does not require finger prick calibration. However, a finger prick test using a blood glucose meter is required in the following situations:
Yes, the FreeStyle Libre system automatically captures readings day and night so that glucose variations – including nighttime lows – can be seen throughout the day, as long as the sensor is replaced at least every 14 days and scanned at least once every 8 hours.
With each scan over the sensor, the reader displays the current glucose reading, the latest 8 hours of glucose history and where glucose levels are heading.
ISF is the fluid around the cells of the tissue below your skin. Glucose can freely move from your blood vessels to this fluid,1 making it a reasonable alternative to blood for measuring glucose. Changes in blood glucose take about 5-10 minutes (“lag time”) to be reflected in ISF glucose.2 However, this is unlikely to impact routine day-to-day treatment decisions. The average lag time of the FreeStyle Libre system is approximately 5 minutes.3 This is why ISF glucose and blood glucose measurements taken at the same time won’t always match – and, in fact, are likely to be different.
No, it can easily be applied without the need for a doctor or nurse – an applicator makes it simple to replace the sensor.
The portion of the sensor that is inserted under the skin is less than 0.4 mm wide and is inserted only about 5 mm under the skin.
The sensor is 5 mm in height and 35 mm in diameter – about the size of a toonie.
The sensor automatically measures glucose levels every minute and stores readings every 15 minutes.
When the sensor is scanned, it automatically transmits 8 hours of data.
A sensor lasts up to 14 days before needing to be replaced.
Each time the sensor is scanned, it automatically transmits data from the last minute, even if that data has not yet been stored.
Yes, the FreeStyle Libre sensor is designed to be water-resistant in up to 1 metre (3 feet) of water. We recommend it not be immersed longer than 30 minutes.
While wearing the sensor, users generally won’t feel anything under the skin. In a clinical user experience study, over 90% of participants did not feel discomfort under the skin while wearing the sensor. 4
The reader can be up to 4 cm away from the sensor and still capture data.
The reader stores up to 90 days of glucose information.
Yes, the reader can get a glucose reading through clothing with a thickness of up to 4 cm.
The FreeStyle Libre reader is designed to be used only with the FreeStyle Precision blood glucose and blood ketone test strips and MediSense control solution.

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 or Android phone 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 phone (PDF 784 KB) 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 or Android phone to install and use the app. See compatibility guide (PDF 69 KB).
Android users can download the FreeStyle LibreLink app* from the Google Play Store. iPhone users can download the FreeStyle LibreLink app* from Apple’s App Store. Please note that the app may not be available for download if your phone is not compatible.
Yes, the FreeStyle LibreLink app* is authorized by Health Canada, licence number 99351, and 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 sensors to wirelessly transmit data to another device.
Please check our compatibility guide (PDF 69 KB) for more information about device compatibility before using the app.
The app has the same indications for use as the FreeStyle Libre system. The FreeStyle Libre flash glucose monitoring system and the FreeStyle LibreLink app* (“App”), when used with the FreeStyle Libre sensor, are indicated for measuring interstitial fluid glucose levels in adults aged 18 years and older with diabetes mellitus. If you are using the FreeStyle LibreLink app,* you must also have access to a blood glucose monitoring system as the App does not provide one. 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 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 Near-Field Communication (NFC) antenna in Android phones vary 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 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, 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.
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 or if hypoglycemia or impending hypoglycemia is reported by the system or when symptoms do not match the system readings.
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. However, people who use the FreeStyle LibreLink app* can connect with their loved ones if they are using a separate app called LibreLinkUp.‡ The LibreLinkUp app‡ allows loved ones to remotely monitor glucose readings.
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, including insulin dosing decisions, when using the app with a FreeStyle Libre sensor, based on guidance from their healthcare professional.
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. Do not scan your sensor if restricted by flight regulations.
WiFi, or a mobile data connection, is only required for initial app setup (downloading/installing the app, creating an account or signing in) and for 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 rooted Android phones or jailbroken iPhones.
After installing the FreeStyle LibreLink app,* tap Sign In. Then, tap Forgot Password. Enter the email address that was used to create the account and follow the onscreen instructions. You will receive an email with a link to reset your password. Follow the link to create a new password, then sign into your account using your new password.
The FreeStyle LibreLink app* is currently available in the following languages:
Note: The FreeStyle LibreLink app* is displayed in the same language as your phone’s operating system language. If you wish to use the FreeStyle LibreLink app* in a different language, choose from one of the supported languages in your phone’s system settings. The FreeStyle LibreLink app* will update the next time it is opened. If the FreeStyle LibreLink app* doesn’t support the language set on your phone, the app will display text in English (US).
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.
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.
You can monitor your glucose 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 sensor with your phone at any time during the sensor life.
Remember that the FreeStyle LibreLink app* and the FreeStyle Libre reader do not share data with each other. 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.
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.
You can 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 Data management & LibreView† section.
