About this app

Levels helps you see how food affects your health. Are you fueling correctly?

Your metabolic health regulates your energy levels, appetite, sleep, weight, mood, long-term health, and more. Levels helps you optimize these with real-time feedback using data from continuous glucose monitors (CGMs).

Levels is backed by advisors who are key leaders in metabolic health: Dr. Robert Lustig; Dr. Mark Hyman; Dr. Sara Gottfried; Ben Bikman, PhD; David Sinclair, PhD; Dom D’Agostino, PhD; Dr. Molly Maloof; Dr. David Perlmutter; Dr. Terry Wahls, & Dr. Gerald Shulman; and was co-founded by Chief Medical Officer Dr. Casey Means.


- “I’m far more aware of my body and its reactions to food, exercise, sleep, and stress. I feel better when I have more food choices than when I was limiting myself too much.” —Laurel Touby, 59, New York

- “I was focused on course correcting my dietary and lifestyle choices to improve my metabolic health, but I realized very quickly that it was much more than that. This is not about deprivation and what I cannot eat.” —Celia Chen, 49, Los Angeles

- “It’s the combination of intermittent fasting and using the CGM that has accelerated my metabolic health optimization. I finally feel like I’ve cracked the code on my body.” —Chris Wise, 42, Los Angeles

Everybody has health goals. Whether you’re tuning your diet, optimizing your exercise, or just trying to stay healthy, monitoring your blood glucose with Levels can help—you’ll finally be able to unlock what will work best for YOUR body.

I really wanted to like Levels. But the product reliability is untenable to warrant anything over 1 star. The data from my CGM fails to appear in the app. This is after hours of debugging and emailing with customer service. I expect quality product and service given the astronomical subscription price. Edit: Changed from 1 to 3 stars due to superior customer service. They were great once they got on a call with me. Still, this doesn't excuse the plethora of product reliability issues.

I leaned about Levels from my friend and was interested to try it out, I placed the order and while waiting for the heat to arrive, I'm trying out the app. The app is currently not letting me log my meals, only two items were added successfully after numerous tries. Very disappointed in the app so far, considering how much this is costing monthly, I may reconsider this once the gear is here.

3/16/24 I really loved the app however I just noticed with the most recent update that they did away with accessing the gallery when logging food. Just until yesterday I was able to. 😞 Last night I didn't get a chance to log my dinner but I did take a pic. Usually when this happened I can just go back, see the time on my photo, go to gallery through the levels app and upload my picture and simply update the time and date and details. Now you have to take the pic through the app and immediately.
