How to Apply and Connect Stelo to the Levels App

Ready to unlock insights into your metabolic health? Your Stelo Glucose Biosensor helps you understand how your body responds to food, exercise, stress, and sleep, while tracking your progress in the Levels app.

Step 1: Download the Stelo by Dexcom app

Download the Stelo app from the Apple App Store or Google Play Store.

Requires iOS 18.6 or later, or Android 13 or later.

Step 2: Sign in or create your Dexcom account

Open the Stelo app and sign in with your Dexcom account.

Your Dexcom and Stelo credentials are the same, so you will use the same email and password for both.
If you are new, you can create an account in the Stelo app in a few quick steps.

Tip: Use your email address instead of your phone number for your user ID. This can help prevent login issues later.

Step 3: Apply your biosensor

Follow the in-app guide for proper placement.

Apply Stelo to the back of your upper arm.
When you are ready, press the applicator firmly against your arm until you feel a click. This means the biosensor is inserted.

Important: Take a photo of the serial number (printed on the applicator or on the side of the box). You may need it if you contact SteloBot for product support.

Step 4: Apply your Levels Performance Cover

Once your biosensor is on, place the Levels Performance Cover over it. This can help keep your biosensor secure during workouts, showers, and day-to-day activity.

Step 5: Connect Stelo to the Levels app

After your biosensor is applied, open the Levels app:

Tap More → Devices
Under Connected Devices, tap Manage
Under Change Model, choose Stelo Glucose Biosensor
Tap Connect Dexcom account
In the pop-up, tap Connect, then follow the prompts to log into your Dexcom account
