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 contextualizes what your glucose is doing — presenting patterns, trends, and correlations that go beyond the raw numbers.
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.

How Much Does Levels Health Cost? 2026 Pricing Breakdown
Levels Health pricing in 2026 runs $199/month billed monthly or $166/month billed annually. Here's the full breakdown — and how to decide which plan makes sense:
Level Zero Health price — is this Levels Health?
"Level Zero Health" and "Levels Health" are sometimes used interchangeably in search queries, but they refer to the same company: Levels Health (levelshealth.com). The platform has no "zero" tier — pricing starts at $166/month on the annual plan or $199/month month-to-month.
| Monthly plan | $199/month — cancel anytime |
| Annual plan | $166/month (billed $1,992/year — save $396) |
| Sensors included | 2 × FreeStyle Libre sensors per month (30-day supply) |
| App access | Full Levels app — metabolic scoring, meal logging, wearables |
| Coaching included | No — app-only (see Nutrisense for coaching) |
| Free trial | Check current offer at Levels website |

The FreeStyle Libre sensors alone cost ~$130–180/month if purchased separately. At $166–199/month, you're paying $0–70/month for the Levels app layer. If you actively engage with metabolic scoring, meal analysis, and wearables data, that's strong value. If you'd only glance at the graph, Abbott Lingo at $89/month delivers the same hardware at a fraction of the cost.
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 | $166–199 | $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.
