The FreeStyle LibreLink app enables you to scan your sensor with your iPhone or Android phone25 so you can monitor your glucose without routine finger pricks.1
With the app you can:
The FreeStyle LibreLink App is only compatible with certain mobile devices and operating systems. Please check our compatibility guide for more information about device compatibility before using the App.
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 2 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. :
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 8 or higher/iOS 15.5 or higher to utilize the NFC capability needed to scan the FreeStyle Libre 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 monitoring. The App can be used instead of or in combination with the FreeStyle Libre Reader for routine monitoring.
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 or the symptoms do not match the system readings.
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.
There’s no need to use a separate blood glucose meter for routine testing.25 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.
You can choose to monitor your glucose levels with either the App, the reader, or both.26 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.
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.
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. 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.
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.
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.
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 e-mail address that was used to create the account and follow the on-screen instructions. You will receive an e-mail with a link to reset your password. Follow the link to create a new password, then sign into your account using your new password.
Android users can download the FreeStyle LibreLink App from the Google Play Store. iPhone users can download the FreeStyle LibreLink App from the Apple App Store. Please note that the App may not be available for download if the App is not approved for use in your country or your phone is not compatible with the App.
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.
E-mail 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 (for more information visit www.LibreView.com).
The App stores your account information, glucose data, notes, and sensor information within the App on your phone, so it is your responsibility to limit access to your phone to protect personal information. The App also automatically uploads this data in LibreView, a secure cloud-based data repository. Please read the Privacy Notice for more information.
If you lose your phone, download the App again on a compatible phone and sign in with your account information. If you have an active sensor and need to reinstall the App, when you sign into your existing account, you can continue using your active sensor until the end of its useful life. You will not be able to view historical data in the new installation of the App, but this data will be available in LibreView.
The FreeStyle Libre system has two main parts: a handheld reader and a disposable Sensor, which is worn on the back of the upper arm. The user wirelessly scans the Sensor with the reader to get glucose readings.
*Based on the Sensor being replaced once every 14 days and scanned once every 8 hours.
The Sensor is intended for single-use and does not require cleaning and disinfection. You may clean the reader using a cloth dampened with a mixture of 1 part household bleach to 9 parts water. Gently wipe the exterior of the reader and allow to air dry.
The FreeStyle Libre system does not contain any latex (other questions about adhesive, Sensor content should be directed to Scientific Affairs).
The FreeStyle Libre reader/sensor is only compatible with the FreeStyle Libre sensor / reader purchased through Abbott official stores / authorized stores or dealers in India. If you are travelling, it is advisable to ensure that you take enough Sensors with you to last the duration of your trip.
The FreeStyle Libre system has been clinically proven to be accurate, stable, and consistent over 14 days. It does not require finger prick calibration and may be used in place of routine finger prick glucose testing.1*

*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.
Yes, the accuracy of the Sensor remains consistent for up to 14 days. The FreeStyle Libre system is clinically proven to be highly accurate, stable, and consistent over 14 days with no finger prick calibrations
LibreLinkUp is a companion App to the FreeStyle LibreLink App, which allows glucose readings to be automatically shared with your caregivers in real-time. Both you and your caregiver must have a network connection to share and receive glucose readings. To add a LibreLinkUp connection through the FreeStyle LibreLink App, simply tap Share in the main menu and follow the on-screen instructions.
LibreView is a cloud-based diabetes management system provided by Abbott and Newyu, Inc. LibreView provides a secure repository for data from your FreeStyle LibreLink App, and allows you to easily share your glucose data with your healthcare professional or others, if you wish. Data is automatically28 uploaded to LibreView when your phone is connected to the Internet.
LibreView lets you create clear, easy-to-understand glucose reports, and allows you to share them with your healthcare professional. LibreView is free and only takes a few minutes to sign up and get started.
To use LibreView, you will need to connect the glucose device to any Windows PC or Mac computer with an Internet connection. Log in with your credentials and then follow the on-screen instructions to upload data.

Yes, see changes below.
The sensor is applied to the back of the upper arm with a simple, disposable device called an applicator. When the sensor is applied, a small (5mm) filament is inserted just under the skin, and held in place with a small adhesive pad. Most patients don't feel pain6 when applying the FreeStyle Libre sensor.
The sensor is 5mm in height and 35 mm in diameter.
No. Apply sensors only on the back of your upper arm. Avoid areas with scars, moles, stretch marks, or lumps. Select an area of skin that generally stays flat during normal daily activities (no bending or folding). Choose a site that is at least 2.5 cm (1 inch) away from an insulin injection site. To prevent discomfort or skin irritation, you should select a different site other than the one most recently used.
The site selected on the back of the upper arm should be clean-shaven.
Yes, there is no interaction expected between tattoo ink and the sensor. It is advised to avoid areas with scars, moles, stretch marks or lumps when applying the FreeStyle Libre sensor.
Sensor performance has been tested to 10,000 feet (3,048 meters) only and is not indicated for use in altitudes > 10,000 feet (3,048 meters). It is not indicated for use above 10,000 feet (3,048 meters).
The sensor automatically stops collecting glucose data and should be removed 14 days after being started.
The portion of the sensor that gets inserted under the skin is less than 0.4 millimeter wide (1 mm is about the thickness of a few strands of human hair) and it’s inserted only about 5 mm under the skin, so most people will not feel the sensor while it is being worn
If there is bleeding that does not stop, remove the sensor, and apply a new one at a different site.
To prevent discomfort or skin irritation, you should select a different location other than the one most recently used.
Some individuals may be sensitive to the adhesive that keeps the sensor attached to the skin. If you notice significant skin irritation around or under your sensor, remove the sensor. Contact your healthcare professional before continuing to use the FreeStyle Libre system.
Applying the sensor may cause bruising or bleeding. If there is bleeding that does not stop, remove the sensor, and apply a new one at a different site.
Yes. The sensor can be worn while bathing, showering, swimming or exercising. The sensor should not be taken below 1 meter of water (3 feet), and should not be submerged in water for more than 30 minutes. The adhesive is designed to keep the sensor securely and comfortably in place for up to 14 days.
Intense exercise may cause your sensor to loosen due to sweat or movement of the sensor. If your sensor comes loose, you may not get readings or have unreliable readings, which may not match how you feel. If this should happen apply and start a new sensor.
Medical grade adhesive bandage or tape can be used. When using an over-bandage, it must be applied at the time of sensor application. The opening/hole in the center of the sensor must not be covered. Additional bandages/tape can be applied but do not remove bandages/tape once applied until sensor is ready for removal.
The disposable sensor is designed to adhere to the back of the upper arm and provide accurate glucose readings for up to 14 days. After 14 days, the user removes the sensor by peeling off the adhesive pad.
No, the wear time of the FreeStyle Libre sensor is not impacted by the clock setting on the FreeStyle LibreLink App. The timer used for wear duration in the FreeStyle Libre sensor is independent of clock time on the FreeStyle LibreLink App.
Pull up the edge of the adhesive that keeps your sensor attached to your skin. Slowly peel away from your skin in one motion. Note: Any remaining adhesive residue on the skin can be removed with warm soapy water, baby oil, or isopropyl alcohol.
A sensor that has been removed or that has fallen off cannot be reused. Users should replace the sensor and start a new sensor. The reader will identify that it is a new sensor and ask users if they want to start it.
After 14 days of wear, the FreeStyle LibreLink App notifies the user that the sensor has ended. The sensor automatically stops collecting glucose data and should be removed. The FreeStyle LibreLink App displays the number of days before the sensor ends. Three days before the Sensor ends, it tells users with the first scan of each day. In the final 8 hours, it tells users with each scan that the sensor should be replaced with a new sensor.
Yes, users can get glucose readings even through clothing by scanning FreeStyle LibreLink App over the sensor. FreeStyle LibreLink App can capture data from the sensor when it is within 1 cm to 4 cm of the sensor.
Users can take as many glucose readings as they want while the sensor is being worn. In order to get a 24 hour glycemic picture users need to scan at least once every 8 hours. The value is updated every minute.
The FreeStyle Libre sensor automatically reports the glucose concentration in the interstitial fluid every minute. It also automatically records the glucose concentration every 15 minutes, storing that data in a rolling 8-hour log.
If for any reason the sensor stops working, please call Customer Service at 1800 2100 998 or email us at email@example.com.
Operational Hours: Mon-Fri from 8:30am - 5:30pm (business days only; no operations on holidays)
If the sensor stops working due to extreme temperature, the user will get an error message indicating ‘Glucose Reading unavailable’. The FreeStyle Libre operating temperature range is 10°C to 45°C.
If restricted by flight regulations, we recommend that mobile phones / FreeStyle Libre Reader be powered off during a flight and not used for scanning a sensor. Aviation regulations dictate that a flight crew may decide that they do not want any electronic devices powered on during a flight regardless of device. In general, the FreeStyle Libre system is not restricted by flight regulations and can be used since it meets the RTCA guidance of use of medical devices on planes.
Please refer to sensor packaging for the expiry date. If customer has multiple sensors, they should use the shortest date first.
The expiration date indicates the last day you can use the sensor. Do not use the sensor past the expiration date. If your sensor expires during the 14-day wear, start a new sensor before the sensor expires.
The Check sensor message occurs when the user tries to check glucose and the sensor does not seem to be “active”. This usually means that the sensor has come loose or has not been applied properly. If it appears to be applied properly, the user should try starting it again. This message will not appear once a glucose result appears.
Abbott’s Diabetes Care Division is committed to making its products safe for the user. Soon after the insertion of a sensor, there are physiological processes that happen as the sensor and the body equilibrates. These processes are part of the body's natural response to the sensor insertion. The equilibration process can vary from one person to another and may not always happen in the same manner for any one person. Therefore, we have decided to let the system equilibrate for 1 hour to ensure that the system is providing accurate glucose readings.
The FreeStyle Libre sensor is approved for use on the back of the upper arm.
If the user has a medical appointment that includes strong magnetic or electromagnetic radiation, for example an X- ray, MRI (Magnetic Resonance Imaging), or CT (Computed Tomography) scan, they need to remove the sensor they are wearing and apply a new sensor after the appointment. The effect of these types of procedures on the performance of the system has not been evaluated.
There is a battery icon on the reader which will indicate battery life. With normal use, the reader can be used for approximately 7 days before it needs to be recharged. A low battery warning will appear on the reader when it needs to be recharged. A low battery message accompanies a result when users have enough charge remaining for about one day of use. Users can scan their sensor when the battery is low and when charging the reader.
The reader can be used while charging via an electrical outlet but cannot be used while charging via a computer. The ability to perform a blood glucose test via a test strip is disabled when the FreeStyle LibreLink App is connected via the USB cable and adapter.
The reader needs to be recharged if it runs out of power. The stored glucose readings on the reader are not lost.
The reader should fully charge in approximately 3 hours if the battery is completely discharged.
For most screens, the reader dims after 45 seconds and turns off after 60 seconds. When doing a finger prick test, removing the test strip will turn off the display.
No, if the sensor is already activated by another reader use of that sensor is not allowed. The reader can only communicate with one sensor at a time. “Sensor already in use” will be displayed.
Users will start losing the oldest glucose readings if the reader is not scanned at least once during an 8-hour period. For example, users scan the reader over the sensor at 13:00 and scans again at 22:00 then users will lose glucose data from 13:00-14:00. The reader will indicate this missing data on reports. There will be a gap on the daily trace that impacts the statistics on sensor usage however it will not be indicated in other reports.
Users can only add/edit notes associated with the last scan or last blood glucose strip test within 15 minutes.
If LO appears on the reader when users scan the reader over the sensor, it means the reading is lower than 40 mg/dL. Users can touch the message button for more information. Users should check their blood glucose on their fingertip with a test strip. If users get a second LO they should contact their healthcare professional immediately.
The FreeStyle Libre system offers a trend arrow with each glucose reading which tells users which way and how quickly glucose levels are changing. So, at any given time, users not only know what their glucose level is currently, but also which way it is heading. Depending on the direction of the trend arrow, users can find out if their glucose levels are changing gradually, moderately, or rapidly, facilitating decision-making.
The direction in which glucose is heading
If HI appears on the reader when users scan over the sensor it means the reading is higher than 500 mg/dL. Users can touch the message button for more information. Users should check their blood glucose on their fingertip with a test strip. If users get a second HI they should contact their healthcare professional immediately.
The typical use of the FreeStyle Libre Reader is 3 years.
Abbreviation: A1c: glycated haemoglobin.
