Getting Started with the Libre 2 Sensors
Updated over 3 weeks ago

If you’re using the Libre 2 sensors to track your biodata you’ll need to download the Libre 2 app to activate your sensor. The Libre 2 sensor will not work with the Libre 3 app and vice versa. The Libre 2 sensor offers a convenient way to monitor your glucose levels continuously with tap-to-transfer. Here’s a simple step-by-step guide to help you set it up and start monitoring:

1. Download the App:

2. Create an Account or Log In:

  • Open the app and follow the prompts to create a new account or log in if you already have created a login (including logins created for the Libre 3 app).

3. Link Libre app & Theia (step 4 of onboarding)

  • Go to the Theia app and complete step 4 of your onboarding process.

    • If you have already completed this step previously, your data will already be connected. If you have different login information between the Libre 2 and Libre 3 app please contact our support team. ​

4. Prepare for Application (Once your sensor is received)

  • Choose the right location: The Libre 2 sensor is applied to the back of your upper arm.

  • Clean the area: Use an alcohol wipe to clean and disinfect the application area. Allow it to dry completely.​

5. Apply The Sensor

  • Peel off the packaging: Open up the Libre 2 sensor packaging and peel off the protective seal.

  • Assemble the applicator: Follow the instructions to connect the sensor applicator to the sensor pack until you hear a click.

  • Apply the sensor: Press the applicator firmly onto the cleaned area of your arm.

6. Activate the Sensor

  • Activate the sensor: Open the Libre 2 app and follow the instructions to scan your new sensor. You’ll need to hold your smartphone close to the sensor to start it.

  • Wait for the warm-up period: The sensor will take about 60 minutes to calibrate before it begins transmitting glucose data.

7. Monitor Your Glucose Levels

  • Scan the sensor as needed: The Libre 2 sensor is tap to transfer and requires you to scan your device once every 8 hours for seamless data transmission. You can scan your sensor at any time to port over the stored data.

    • Consequently, you will need to scan your sensor 3 times a day to avoid data loss. We find that right when you wake up, middle of the day, and after dinner are great check-in times.

  • Log Activities:Log your activities in Theia to correlate inputs with your body's reactions.

Important Notes

  • The Libre 2 app is specifically for Libre 2 sensors. If you are using a different model (such as Libre 3), you’ll need the corresponding app. If you have received the Libre 2 sensor, you must use the Libre 2 app.
