About the Stelo Glucose Biosensor
Meet Stelo, the first FDA-cleared glucose biosensor available without a prescription. This breakthrough technology makes continuous glucose monitoring more accessible than ever, helping you understand how your body responds to food, exercise, and daily choices.
What makes Stelo special?
Levels' mission has always been to increase access to individual, actionable data about metabolic health. It's why we started helping people get continuous glucose monitors six years ago. So we're thrilled that we can now offer our members Stelo, an over-the-counter glucose biosensor from Dexcom.
Stelo is built on Dexcom's most accurate continuous glucose monitoring technology and designed specifically for adults 18+ who aren't using insulin. Unlike traditional CGMs that require prescriptions, Stelo is available over-the-counter, removing barriers that previously kept this powerful health tool out of reach.
How Stelo works with Levels
Continuous insights: Stelo delivers glucose readings 24/7 directly to your smartphone for up to *15 days per biosensor. The device calculates a glucose value every 5 minutes and transmits that data via Bluetooth to your mobile device every 15 minutes.
Seamless setup: Biosensor pairing typically takes less than 5 minutes. After a 30-minute warm-up period, you'll start receiving continuous glucose data that integrates beautifully with your Levels app experience.
Smart data storage: Stelo can hold up to 24 hours of your most recent glucose data when the Bluetooth signal is weak or disrupted, so you won't miss important insights.
No calibration needed: Stelo is designed to function without requiring fingerstick calibrations – there's no need to calibrate the biosensor, which means less hassle for you.

*A study was conducted to assess the sensor life where 77.9% of sensors lasted the full 15 days. In other words, when using the product per the package labeling, approximately 20% of sensors may not last for the full 15 days, 10% of these sensors may last less than 12 days.
