What is Levels Health?
Levels Health is a metabolic health platform that combines continuous glucose monitoring with a proprietary app designed to turn raw CGM data into actionable lifestyle insights. Founded in 2019, Levels has built a significant following among biohackers, athletes, and health-conscious professionals who want to understand their metabolic responses without the clinical framing of traditional diabetes CGM tools.
The core product: you receive FreeStyle Libre sensors on a monthly subscription, along with access to the Levels app. The app processes your glucose data in real time and overlays it with your food logs, exercise, sleep, and stress data to generate a holistic picture of your metabolic health.
What makes Levels different from simply buying a CGM and downloading the manufacturer's app is the metabolic scoring system and the quality of the insights layer. Levels has invested heavily in making CGM data interpretable for non-clinical users — the app tells you not just what your glucose is doing, but what it means and what to do about it.
Levels is designed for people without insulin-dependent diabetes. If you use insulin, you need a prescription CGM like the Dexcom G7 or FreeStyle Libre 3, not a wellness platform like Levels.
The Levels app — the real product
The hardware is a FreeStyle Libre sensor. The app is where Levels earns its premium. It's genuinely the most sophisticated metabolic health app available in 2026, and it sets Levels apart from simply buying an OTC CGM and using the manufacturer's app.
CGM hardware — FreeStyle Libre
Levels ships FreeStyle Libre sensors — the same hardware used in Abbott's prescription CGM lineup. The sensor itself is excellent: small, 14-day wear, factory calibrated, and no scanning required (it streams continuously via Bluetooth).
Accuracy is strong — the Libre achieves a MARD of approximately 7.8% in clinical studies, making it one of the most accurate CGMs available. For non-clinical metabolic health use, this is more than sufficient.
One thing to understand: you're not paying Levels for premium hardware you couldn't get elsewhere. You're paying for the app layer on top of that hardware. The Levels app is what justifies the price premium over simply buying Abbott Lingo ($89/month) or Dexcom Stelo ($99/month) directly.
| CGM sensor | FreeStyle Libre (Abbott) |
| Sensor wear time | 14 days |
| MARD accuracy | ~7.8% |
| Warmup time | 60 minutes |
| Calibration required | No |
| Prescription required | No |
| App compatibility | iOS and Android |
| Wearables integration | Apple Health, Oura, Whoop, Garmin |
How much does Levels Health cost?
Levels is a premium product with premium pricing. Here's how it breaks down:
- 2 FreeStyle Libre sensors (30-day supply)
- Full Levels app access
- Metabolic scoring and insights
- Food logging and meal analysis
- Wearables integration
- 2 FreeStyle Libre sensors (30-day supply)
- Full Levels app access
- Metabolic scoring and insights
- Food logging and meal analysis
- Wearables integration
- Save $396 vs monthly billing
The FreeStyle Libre sensors included in Levels cost approximately $130–180/month if purchased separately. This means you're paying roughly $20–70/month for the Levels app itself — a reasonable premium if the insights genuinely change your behavior. If you'd only use the raw glucose data, consider Abbott Lingo instead.
Levels Health vs Nutrisense
These two are the dominant CGM subscription platforms for non-diabetic users. They take different approaches:
| Feature | Levels Health | Nutrisense |
|---|---|---|
| Monthly cost | $199–299 | $179–299 |
| CGM sensor | FreeStyle Libre | FreeStyle Libre |
| Dietitian coaching | No | Yes — included |
| App sophistication | Best in class | Very good |
| Metabolic scoring | Yes — detailed | Basic |
| Lab integration | Yes | No |
| Wearables integration | Oura, Whoop, Garmin | Apple Health only |
| Best for | Self-directed optimizers | Guided support seekers |
Bottom line: Levels wins on app quality and integrations. Nutrisense wins on human support. If you're a self-directed person who wants the best data tools, choose Levels. If you want a dietitian to interpret your results and guide you, choose Nutrisense.
