Once you've created an account with Theia you will need to complete 8 simple onboarding steps. These steps can be viewed at any time from the "Onboarding" section of the Theia menu.

The Theia app is available in the App Store & the Play Store.

As the sensors are prescription devices we require all patients to complete a questionnaire prior to the sensor being shipped.
​
Once the questionnaire has been completed we will start the prescription process. When the prescription process has been completed we will ship the sensors and you will receive a tracking link within the "Sensor Order" section of your Onboarding steps.

Please note, this step is specific to the sensor that you received.

For the initial activation of the sensor, you will need to download a second application that's available on both the App Store & the Play Store. You'll find direct links to the required CGM app in your onboarding steps.

The Libre 2/3 app requires NFC functionality in order to activate the sensor. This functionality is available on most phones manufactured after 2016.

Once the CGM app has been downloaded, you will need to create an account. Please make sure to remember the username (email/phone number) and password created here, as you'll need them in the following steps.

For Libre 2/ Libre 3 sensors, you will need to create a Libre account that can be used across all Libre products. For Dexcom, you will need to create a Dexcom account that can be used with the G7.

You will need to enter the account information that was created within the CGM app into Theia. This is the username and password created in the previous step. If you're having trouble, see this guide.

You will be provided with a walkthrough on how to log an activity. Theia promotes the usage of pictures over text, as that's an easier behavior to learn and is less cumbersome than detailed caloric logging.

For a more detailed guide on how to log activities, check out this article.

Once the sensors have been delivered, you will need to apply the sensor. Sensor application is quick and painless. Step-by-step instructions and video guides will be provided in your Theia account.

After a brief warmup period for your sensor, you'll have real-time glucose data available in your Theia app and have completed your onboarding.
