What Levels does
Levels is a general-wellness software company. Members use personalized data from biosensors like the Stelo Glucose Biosensor to discover their optimal diet, understand how meals and habits move their glucose, and build the food + exercise routine that fits their body.
The platform displays data from the Stelo Glucose Biosensor alongside food and activity logs, plus AI-powered habit tracking and comprehensive lab panels. The point isn't the sensor — the point is what the data teaches you about how your specific body responds to what you eat.
Why this fits the longevity research community
Post-meal glucose response is one of the more actionable metabolic markers available to non-clinical adults. Levels provides the software layer that turns raw glucose readings from the Stelo Glucose Biosensor into daily behavior signal — which foods spike you individually, which time-of-day windows matter, which sleep and exercise patterns move glucose stability. Members use this to inform decisions the way the broader longevity community uses biomarker testing.
The Stelo Glucose Biosensor
Stelo is the FDA-cleared over-the-counter glucose biosensor from Dexcom. Two biosensors per month, 30 days of continuous wear coverage. Levels provides access to the Stelo Glucose Biosensor and displays the data alongside food, exercise, and sleep logs. No prescription required.
