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.

Who it's NOT for

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.

📊
Metabolic Score
Every meal, workout, and day gets a score based on glucose response. The scoring system translates complex CGM data into a single number you can track and improve over time.
🍽️
Meal logging & analysis
Log meals and see exactly how your glucose responds. Over time, Levels builds a personalized database of how your body reacts to specific foods — more accurate than any generic GI table.
😴
Sleep & recovery tracking
Integrates with Apple Health, Oura, and Whoop to correlate sleep quality with next-day glucose patterns. The connection between poor sleep and elevated fasting glucose becomes visible and quantifiable.
🏃
Exercise integration
See how different types, timing, and intensity of exercise affect your glucose. A post-meal walk vs a fasted morning run produce very different glucose signatures — Levels shows you both.
📈
Zone scoring
Levels defines glucose "zones" — stable, slightly elevated, and spike — and shows what percentage of your day you spend in each. Time in the stable zone is the primary metric to optimize.
🔬
Lab integration
Upload blood test results and Levels contextualizes them alongside your CGM data — HbA1c, fasting insulin, triglycerides. A genuinely useful feature for people doing comprehensive metabolic testing.

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.

Is Levels Health worth the cost?

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:

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.

Who should use Levels Health?

Choose Levels if you...
  • Are a self-directed health optimizer who wants the best data tools
  • Use Oura, Whoop, or Garmin and want integrated metabolic insights
  • Want the most sophisticated metabolic scoring available
  • Are interested in correlating blood test results with CGM data
  • Have already used basic CGM and want more depth
  • Are a biohacker or longevity-focused individual
Consider alternatives if you...
  • Want dietitian coaching alongside your data (choose Nutrisense)
  • Are on a tight budget (choose Stelo at $89/month)

Frequently asked questions

Is Levels Health a good CGM? Full review summary
Levels Health is the strongest metabolic analytics app available for CGM users in 2026. It uses FreeStyle Libre sensors and adds advanced metabolic scoring, meal analysis, wearables integration (Oura, Whoop, Garmin), and lab upload. The trade-off is cost — at $166–199/month it is significantly more expensive than buying sensors directly. For users who engage actively with the data, it delivers genuine value. For users who primarily want raw glucose readings, Abbott Lingo at $89/month or Dexcom Stelo at $99/month are stronger value alternatives. GlucoseForge rating: 8.7/10.
What is the Levels app and how does it work?
The Levels app connects to your FreeStyle Libre sensor via Bluetooth and overlays metabolic scoring on top of the raw glucose data. Each meal is scored based on your glucose response — how high your glucose rose, how quickly it peaked, and how fast it returned to baseline. The app also integrates sleep data from Oura and Whoop, activity from Garmin and Apple Health, and allows you to upload lab results for correlation with CGM trends. The app is iOS and Android compatible and connects to Apple Health.
Levels Health vs Nutrisense — which is better?
Levels Health is better if you want the strongest analytics app and are comfortable interpreting data yourself. Nutrisense is better if you want registered dietitian coaching alongside your glucose data. Both use identical FreeStyle Libre sensors. Levels costs $166/month annual; Nutrisense costs $179/month annual. See our full Nutrisense vs Levels Health comparison.
Does Levels Health require a prescription?
No. Levels ships FreeStyle Libre sensors directly without requiring a prescription. The platform is designed for non-insulin-using adults who want metabolic health insights.
Is Levels Health covered by insurance?
No. Levels is an OTC wellness product and is not covered by insurance. Some HSA/FSA accounts may cover CGM-related expenses — check with your plan administrator. If you have a diabetes diagnosis, ask your doctor about prescription CGM coverage instead.
How does Levels compare to just buying an OTC CGM?
The hardware is the same (FreeStyle Libre). The difference is entirely in the app. Levels' metabolic scoring, meal analysis, and wearables integration are significantly more sophisticated than the manufacturer's app. Whether that's worth the price premium depends on how much you'll engage with the insights.
Can I cancel Levels Health anytime?
Yes — monthly subscriptions can be cancelled at any time. Annual subscriptions are typically non-refundable after the initial period. Check the current terms on Levels' website before committing to an annual plan.
Does Levels work outside the United States?
Levels is currently only available in the United States. International users should look at Nutrisense (also US only) or local alternatives depending on their region.
Is there a free trial for Levels Health?
Levels has offered trial periods and money-back guarantees at various points. Check their current website for the latest offer — terms change periodically.
