Levels vs Nutrisense (2026)

Levels and Nutrisense are the two biohacker CGM programmes everyone shortlists. Both ship the same Dexcom G7 sensor — the most accurate consumer CGM hardware on the market — so the accuracy ceiling is identical. The real difference is the wrapper: Levels bets on app intelligence and a deep content library; Nutrisense bets on a registered dietitian who reviews your data weekly.

VERDICT: TIE

It is a deliberate tie that depends on what you want. Levels for the deepest insight engine on your own; Nutrisense for a registered dietitian working through your data with you each week.

Levels Health8.4 / 10

Levels

CGM coaching programme (Dexcom G7)

The most polished biohacker CGM programme — best-in-class insights at the highest price in the category.

Nutrisense8.0 / 10

Nutrisense

CGM coaching programme (Dexcom G7 + RD coach)

The strongest human-coaching CGM programme — a registered dietitian alongside Dexcom G7 data.

Head-to-head breakdown

  • Sensor and accuracy

    Both ship Dexcom G7 — same hardware, same MARD ~8.2%, same 10-day wear. Indistinguishable on sensor.

    Tie

  • Insight depth (app)

    Levels has the deeper meal-impact engine — AUC decomposition, food-by-food ranking history, time-in-range views. Nutrisense is competent but less granular.

    Levels

  • Human coaching

    Nutrisense includes a registered dietitian (RD) for every subscriber with weekly written reviews and in-app messaging. Levels is app-only by default.

    Nutrisense

  • Content library

    Levels has a substantial editorial library backed by its medical advisory board. Nutrisense leans on the coach for guidance instead.

    Levels

  • Integration

    Both integrate with Apple Health; Levels adds Oura, Nutrisense adds Cronometer and ketone meters. Comparable.

    Tie

  • Price

    Levels: $199/month. Nutrisense: $280–$310/month including the RD. Levels is the cheaper of the two — what you pay for at Nutrisense is the coach.

    Levels

Choose Levels

Choose Levels if you trust app intelligence over human coaching, want the deepest food-by-food insight engine in the category, and are using CGM as a self-experiment instrument.

Choose Nutrisense

Choose Nutrisense if accountability through a registered dietitian is what makes the programme work for you, and you would rather have a person interpret the data weekly than an app.

The short version

Levels and Nutrisense ship the same Dexcom G7 sensor. The decision is between two coaching models — app intelligence (Levels) or a registered dietitian (Nutrisense). Pick on which model you will actually engage with.

When Levels is the right pick

Levels is the right shape for users who treat CGM as a self-experiment instrument: log meals, run protocols, read the curves, iterate. The app does the heavy lifting and the content library backs it up — which is enough for users who would have skipped the weekly RD message at Nutrisense anyway. It is also $80–$110/month cheaper.

When Nutrisense is the right pick

Nutrisense is the right shape when accountability is the value. A registered dietitian reviewing your data weekly, sending written summaries and answering questions in-app is the difference between sustained behavioural change and a $200 month of charts for many users. Pay the premium only if you will use the coach.

Common questions

Are Levels and Nutrisense really the same hardware?

Yes. Both ship Dexcom G7 — the same sensor with the same 10-day wear, 30-minute warm-up and ~8.2% MARD accuracy versus reference plasma glucose. The differentiation is entirely in the app, the coaching layer, and the price.

Is the Nutrisense dietitian worth $80/month over Levels?

For users who need accountability or do not trust themselves to interpret meal data alone — yes. For users who would read the app summaries on their own and skip the weekly RD message anyway — no. The honest answer is that the coach is the value, and the coach is only valuable if you actually engage with them.

Which has better food logging?

Roughly comparable. Levels integrates MyFitnessPal; Nutrisense integrates MyFitnessPal and Cronometer. Both surface meal-by-meal glucose curves with similar UX. Neither has industry-leading first-party food logging.

Can I switch between them?

Yes — both run on the same Dexcom G7 sensor and there is no platform lock-in for the hardware itself. Historical data does not transfer; if you switch, you start fresh in the new app.
