Both platforms put a continuous glucose monitor on your arm and give you metabolic data. The difference is what they do with it — and which one serves your goals better.

Levels is the better platform for people who want to deeply understand their own metabolic data and make self-directed changes. The app is genuinely best-in-class — the glucose zone visualization, food score system, and wearable integrations give you the richest picture of how food, exercise, stress, and sleep affect your glucose.
Levels launched with a waitlist in 2021, backed by prominent health figures, and has iterated quickly. The metabolic score — a composite of glucose stability metrics — gives you a single daily number that responds measurably to lifestyle changes. If you want to run structured experiments (does protein-first eating change my post-meal curve?) Levels gives you the tools to do that well.
Choose Levels if: You're self-directed, data-oriented, and want the best analytical app. You don't need a dietitian — you need better data and the tools to act on it yourself.
Try Levels Health →Nutrisense's core differentiator is the registered dietitian coaching included in the subscription. After your first month of CGM data, a Nutrisense RD reviews your patterns and provides personalized recommendations. For people who want expert interpretation alongside the data — not just raw numbers — this is a meaningful difference.
The Nutrisense app is functional but less polished than Levels. The coaching model adds cost but also accountability. If you've tried making dietary changes on your own and want a human layer of guidance connecting your glucose data to actionable nutrition changes, Nutrisense provides that.
Choose Nutrisense if: You want expert guidance interpreting your results. You'd benefit from a registered dietitian reviewing your patterns and making specific recommendations, not just data to interpret yourself.
Try Nutrisense →If $200/month is too much for a first experiment, the Abbott Libre 3 is now available over the counter at most US pharmacies for ~$50 per sensor. No subscription required. Use it with the LibreLinkUp app or a compatible third-party app. You lose the analytical layer of Levels or the coaching of Nutrisense, but you get the core glucose data for a single 14-day experiment at a fraction of the cost.
