If you’re using the Libre 3 sensors to track your biodata you’ll need to download the Libre 3 app to activate your sensor. The Libre 3 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 via Bluetooth. Here’s a simple step-by-step guide to help you set it up and start monitoring:

1. Download the App:

• iOS: https://apps.apple.com/us/app/freestyle-libre-3-us/id1524572429

• Android: https://play.google.com/store/apps/details?id=com.freestylelibre3.app.us
   

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 2 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 3 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

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

6. Activate the Sensor
