Summary at a glance
Levels pairs a continuous glucose monitor (a small arm sensor that reads your blood sugar all day) with an app that scores your meals 1-10 — users love watching food affect them in real time.
The most consistent praise across sources: real-time meal scores, lasting habit change, and CGM access without the doctor-and-insurance hassle.
The most consistent complaints: the cost (sensors run about $100/month on top of the app), a scoring window that misses late spikes, frequent sync failures, and glucose targets tight enough to stress some people out.
Current app membership starts at $15/mo ($80/yr); lab-and-CGM bundles run $499/yr (Core) to $1,999/yr (Complete).

TL;DR verdict
Levels is a metabolic-health app built around a continuous glucose monitor — a small sensor you wear on your arm that reads your blood sugar day and night. You log meals, and Levels scores each one from 1 to 10 based on how your glucose responds.
Here is the honest shape of it, drawn from real reviews.
People who love it love the feedback loop. Watching a specific food spike you, then fixing it, is genuinely motivating. A self-funded 2026 tester put it plainly: "The food scores are addicting and I have genuinely changed some things that I do in my life because of this app and the data is fascinating." youtube.com
People who cool on it point at the same few things: the price, a scoring window that misses late spikes, sync glitches, and targets tight enough to tip into food anxiety.
So it fits a curious, non-diabetic optimiser who wants short bursts of data. It fits budget-conscious buyers and anyone with a history of disordered eating far less well.
Continuous glucose monitor worn on the upper arm in daily lifeBest for a non-diabetic optimiser who wants short, data-rich bursts (a couple of weeks, a few times a year) to learn how their own meals affect them — not year-round wear, and not anyone prone to food anxiety.
LevelsAcross App Store reviews, Reddit threads, and two independent testers, the strongest and most repeated theme is that real-time meal scores drive real behaviour change — but the cost, the scoring blind spots, and tight glucose targets are just as consistently flagged.
What is Levels?
Levels makes the software, not the sensor. You wear a Dexcom continuous glucose monitor, and Levels reads the data and turns it into meal scores, trends, and coaching.
The core loop is simple. You log a meal, the app watches your glucose for the next couple of hours, and you get a score. As the 2026 tester described it: "You log a meal and levels watches your glucose for two hours and then it gives you a score from 1 to 10." youtube.com
That comparison-over-time angle is what reviewers keep coming back to. One App Store reviewer summed up why it clicks: "half a banana will cause a glucose spike for me, but may have no measured impact for you!" apps.apple.com
Beyond glucose, Levels layers in AI photo food logging, adaptive in-app programs, imported wearable data (Apple Health and Apple Watch), and — on its paid tiers — lab panels reviewed by a licensed clinician. It is US-only and iOS-first.
Levels does not make the glucose sensor — it reads data from a Dexcom monitor, which means you run two apps side by side.
Blood work, scans, test results, medical reports — finally in one place and connected to how you actually feel. aelívra tracks biomarkers and health records over time, so you can see what's trending in the right direction and walk into your next appointment knowing exactly what to discuss.
What does Levels cost?
Pricing has changed over time, so here are the current figures from Levels' own pages levels.com — not the older numbers you will see quoted in reviews.
The entry point is an app membership: $15/mo, or $80/yr. That gets you the Levels app, AI photo food logging, AI health insights, adaptive programs, wearable-data import, and past-bloodwork uploads. Crucially, the CGM sensors and lab panels are paid add-ons on this tier.
From there, two bundles fold in labs and sensors:
A legacy Classic plan ($24/mo or $288/yr) still appears on the how-it-works page. Levels is also HSA/FSA eligible via Truemed.
Here is where user reviews and the official pricing part ways. Reviewers quote their own out-of-pocket math, and it runs high. The 2026 tester warned that continuous, year-round wear "is going to cost you $1,400 for the year and for some it'll be mentally exhausting and you'll start obsessing over every meal." youtube.com Treat figures like that as a real user's lived cost — sensors alone run roughly $100 a month — rather than a current list price.
The headline app membership does not include sensors or labs on the entry tier — budget for roughly $100/month in sensors on top if you want continuous glucose data.

What users consistently praise
Two things come up again and again: the real-time feedback, and the habit change it drives.
The meal scores are the hook. Seeing a number attached to what you just ate, then beating it tomorrow, turns nutrition into something you can act on. Reviewers describe it as motivating to the point of "addicting" youtube.com.
The behaviour change sticks for many. Walking after meals, protein and fat before carbs, eating earlier — these show up across App Store reviews and both independent testers.
The AI photo food logging earns specific praise. The 2026 tester noted: "You just take a picture of your plate and it identifies everything and it works amazingly well." youtube.com
And for a lot of people, the real unlock is simply access. One App Store reviewer valued "the access to the Dexcom without the dr hassle over insurance" apps.apple.com — no prescription, no waiting.
There is also a strong signal on how to use it well. In a late-2023 r/PeterAttia thread, the top-voted approach was short bursts: "The way I have used it, which I think is useful, is literally 1-2 weeks twice a year." reddit.com Learn what spikes you, then stop.
The two columns below summarise the trade-off reviewers describe.
Levels app showing a real-time glucose graphLevels — what reviewers report
Real-time meal scores show how specific foods spike your glucose, and you can compare the same meal across different days
Users report lasting habit change — walking after meals, protein and fat before carbs, eating earlier
AI photo food logging is well-liked for accurately identifying meals
CGM access without the insurance or doctor hassle, and no prescription needed for the underlying sensor
Expensive — sensors run about $100/month on top of the app membership
The two-hour meal-scoring window can miss late dinner spikes, and extending it does not help
Two-app setup (Dexcom sensor app plus Levels) and reviewers report frequent sync failures
Tight glucose targets can push a restrictive low-carb diet and, for some, food anxiety
Common complaints
The complaints are consistent enough to plan around. Note that several come from reviews that are a year or more old, so we date-frame them.
The scoring misses late spikes. The 2026 tester ate a pizza, scored a six, then spiked hours later — and the score never updated. As they put it: "So, I extended the scoring window to 3 hours, and the score didn't change." youtube.com
Sync fails often. In an undated App Store review, one user wrote: "75% of the time I have to close the app and reopen it to get it to sync and add the newest glucose data. This is the app's primary function and it fails." apps.apple.com
The AI coach can be confidently wrong. Another undated App Store review flagged it: "This 'coach' not only gives you bad advice it sometimes pulls the wrong data and then confidently analyzes it" apps.apple.com.
The guidance can feel generic. The same critique noted: "There is no pattern recognition, no personalized dietary suggestions and oddly the overall tone is cold to neutral" apps.apple.com — and said it is not built for serious athletes.
Wearing the sensor is not painless. In a 2024 blog review, the tester wrote: "I hated punching that CGM into my skin; if you get it wrong, you can be in a lot of discomfort and even bleed through your clothes." ablueskymind.com The two-app workaround also drew a shrug: "It's clunky, but it works." youtube.com
The targets are tight. In a 2023 r/levelshealth thread, a reviewer argued Levels "has also chosen an extremely tight range for 'ideal' glucose levels, not to exceed 110 mg/dL, which will funnel most people into a low-carb/keto-style diet." reddit.com
And it can tip into anxiety. In a 2022 r/levelshealth thread, one user wrote bluntly: "I can't wait for the eating disorder this device is going to give me." reddit.com
Several complaints come from reviews 1-4 years old. Product details like AI-coach quality and sync reliability may have changed since — treat older quotes as date-stamped snapshots, not the current state.
Who Levels is for — and who it is not
Levels fits you if you are a curious, non-diabetic person who wants to learn how your own meals affect you, and you are happy to do it in short bursts. The pattern that works, per reviewers, is a week or two at a time rather than year-round wear.
It fits less well on a budget. In a 2023 r/levelshealth thread, a long-time user reflected that the sensor, not the software, was the real value: "The app is cool but the monitor is the main thing." reddit.com
It fits serious athletes poorly. Reviewers say the "all spikes are bad" lens misfires for people whose training deliberately moves their glucose apps.apple.com.
And it fits anyone with a history of disordered eating poorly. A clinician in a late-2023 r/PeterAttia thread called continuous monitoring for healthy people "overkill for most people to use by themselves." reddit.com
If you want a clear picture of your metabolic and biomarker data over time — without the food-anxiety risk — a tracking approach that connects labs and how you actually feel may serve you better than a live glucose feed.
Person wearing a continuous glucose monitor sensorHow we researched this review
We have not used Levels ourselves. This review aggregates public user sentiment, gathered on 2026-07-16, across four source types.
Apple App Store apps.apple.com — Levels holds a 4.7/5 rating across roughly 6,600 ratings, a large and healthy base. We captured 10 full-text reviews verbatim, spanning five-star advocacy and pointed one-and-two-star critiques. The store does not surface per-review dates, so we date-frame App Store quotes as undated; one references an AI-coach feature added around 2024 or later, so at least one critical review is recent.
Two independent, self-funded testers — a 2026 video tester who bought their own subscription and sensors youtube.com (they use an affiliate link, which we note for transparency), and a 2024 blog review ablueskymind.com from a one-month self-funded test. The 2026 account is our strongest fresh datapoint.
Seven Reddit threads reddit.comreddit.comreddit.com — five from r/levelshealth and two from r/PeterAttia, posted between 2022 and 2025. All are more than a year old, so every Reddit quote here is date-framed.
Trustpilot trustpilot.com — status: none. Two independent scraping attempts returned no reviews for levels.com, so Levels has effectively no Trustpilot presence. We did not draw any quotes from it, and we are not inventing any.
One gap worth naming: there is no live Google Play listing — Levels is iOS-first — so this sentiment skews toward iPhone users. Frequencies here are qualitative judgments, weighted toward themes that recur across at least two independent sources.
This is an aggregation review of public sentiment as of July 2026 — not first-hand testing. Trustpilot returned no usable reviews, and there is no Google Play listing, so the picture skews toward iOS users.
Frequently asked questions
Do you need a prescription to use Levels?
No. Reviewers repeatedly note that the underlying Dexcom sensor needs no prescription, and that skipping the doctor-and-insurance route is a big part of the appeal apps.apple.com.
How much does Levels really cost?
The app membership starts at $15/mo ($80/yr), with Core at $499/yr and Complete at $1,999/yr per Levels' own pricing levels.com. But sensors are an add-on at roughly $100/month, so real-world spend runs higher — one 2026 tester pegged year-round use near $1,400 youtube.com.
Is Levels worth it for a healthy, non-diabetic person?
Reviewers are split, and the most common advice is to use it in bursts. In a late-2023 r/PeterAttia thread, the top-voted view was "literally 1-2 weeks twice a year" reddit.com — learn your patterns, then stop, rather than wearing it continuously.
Can Levels cause food anxiety?
For some people, yes. Its glucose targets are tighter than typical clinical guidance, and reviewers have flagged the obsessive edge — one 2022 thread went as far as "I can't wait for the eating disorder this device is going to give me." reddit.com If you have a history of disordered eating, approach with real caution.
Does it work on Android?
Levels is iOS-first, and we found no live Google Play listing as of July 2026. If you are on Android, check current availability before committing.
