Levels
Real-time metabolic health insights via CGM
What is Levels?
How to Use Levels
Getting started with Levels is straightforward. Once you sign up and complete the health screening, you'll receive your CGM sensors in the mail. Here's a step-by-step walkthrough of setting up the sensor, connecting the app, and interpreting your first glucose data points.
Sign Up and Complete the Health Screening
Visit levels.link and choose your program length (monthly, 3-month, or 6-month). You'll fill out a brief online health questionnaire that a licensed clinician reviews to determine if CGM monitoring is appropriate for you. Most users receive approval within one business day.
Apply Your First CGM Sensor
When your sensor kit arrives, wash your arm and use the included applicator to press the small sensor onto the back of your upper arm. The insertion is nearly painless — a tiny flexible filament sits just under the skin. The sensor activates within about an hour and starts streaming glucose data to the Levels app.
Set Up the App and Log Your First Meal
Download the Levels app from the iOS or Android store and create your account. Scan the sensor's QR code to pair it via Bluetooth. Start logging meals by taking a photo or typing ingredients — the app will score each item based on your glucose response and show you how your blood sugar changes in the hours after eating.
Explore Your Glucose Patterns and Insights
After a few days of tracking, the app begins to reveal patterns. Check the daily timeline view to see how different meals, workouts, and sleep quality affect your glucose levels. Use the weekly summary to identify trends, and read the in-app educational articles to understand what your numbers mean for your metabolic health.
Levels Core Features
Levels Use Cases
- 1Health optimizers and biohackers use Levels to identify exactly which foods spike their blood sugar, enabling them to fine-tune their diet for steady energy, better focus, and long-term metabolic resilience.
- 2People with prediabetes or a family history of type 2 diabetes leverage real-time glucose feedback to make dietary adjustments that keep blood sugar in a healthy range, often catching problematic patterns before they become chronic.
- 3Athletes and fitness enthusiasts track how pre- and post-workout nutrition affects glucose levels and recovery, using the data to optimize fueling strategies for peak physical performance.
- 4Anyone struggling with afternoon energy crashes, brain fog, or unexplained fatigue can pinpoint trigger foods and lifestyle habits that destabilize glucose, then build a routine that sustains mental clarity all day.
- 5Weight management seekers use the meal-scoring feature to choose foods that promote satiety and stable insulin response, replacing calorie counting with smarter, data-backed eating decisions.

Who Should Use Levels?
Levels is best for health-conscious individuals who are ready to move beyond guesswork and invest in personalized metabolic data. It's ideal for biohackers, athletes optimizing performance, people with prediabetes or a family history of metabolic disease, and anyone experiencing chronic energy crashes or weight management struggles who wants hard numbers instead of generic diet advice.
Levels is the gold standard for consumer-grade continuous glucose monitoring. It turns vague health advice into personalized, real-time data that actually changes behavior. The sensor is comfortable enough to forget you're wearing it, and the app is beautifully designed — making complex metabolic insights accessible to anyone. The biggest hurdle is price; at $199/month it's a serious investment, and the lack of insurance coverage stings. But for those committed to understanding their body at a deeper level, Levels delivers on its promise with polish and scientific credibility.
