Levels vs Nutrisense: two ways to spend $1,000 on your own blood sugar
Both wrap the same continuous glucose sensors in software. One sells you a system to learn; the other sells you a dietitian to interpret. The gap between their sticker prices is about $3,300 over two years — and there's a third option neither of them puts on the pricing page.
Levels is the better software and far cheaper; Nutrisense is worth it only if you'll use the dietitian. Levels runs $80–$1,999 a year depending on tier; Nutrisense starts at $179 a month ($2,148 a year), with coaching often billed to insurance. If you're metabolically healthy and self-directed, the cheapest honest path is an over-the-counter sensor plus Levels' $80/year app tier.

What does each one actually cost in 2026?
Both companies restructured pricing in the past year, and most comparison articles you'll find are quoting numbers that no longer exist. Here is what their own sites showed on 1 September 2026.
| Plan | Monthly | Annual | Sensors included | 24-month total |
|---|---|---|---|---|
| Levels — Build Your System | $15 | $80 | None (BYO or add on) | $160 + sensors |
| Levels — Core | $41 | $499 | 1 month of CGM | $998 |
| Levels — Complete | $167 | $1,999 | 2 months of CGM | $3,998 |
| Nutrisense — CGM programme | from $179 | $2,148 | Yes, ongoing | $4,296 |

The third option neither of them advertises
Over-the-counter glucose sensors no longer require a prescription in the US. Dexcom Stelo runs roughly $89–99 a month; Abbott Lingo is about $49 per 14-day sensor. Levels' cheapest tier explicitly supports bringing your own sensor and works without one at all.
So the cheapest legitimate configuration for a metabolically healthy adult who wants to run a two-month experiment is:
- Levels "Build Your System" at $80 for the year, plus
- two months of an OTC sensor at roughly $100–$180 total,
- total: about $180–$260 — against $358 for two months of Nutrisense, or $998 for two years of Levels Core.
Nobody markets this configuration because it is the least profitable one. It is also, for most readers of this site, the correct one. You are not buying a lifelong subscription to glucose; you are buying a short, sharp experiment. Everything after month three is repetition.
Does CGM actually do anything for people without diabetes?
Honestly? The evidence is thinner than either company's marketing implies, and the useful findings point somewhere cheap.
A 2025 systematic review in Cureus pooled seven studies covering roughly 1,127 non-diabetic participants using CGM to guide lifestyle change. Its conclusion was carefully hedged: CGM "shows promise for personalising lifestyle interventions", but direct evidence on traditional cardiovascular risk factors was limited, and there is nothing yet on hard cardiovascular endpoints.
The specific findings inside that review are more interesting than the headline:
- Timing beats composition. A 20-minute walk taken before your individual post-meal glucose peak cut the four-hour incremental glucose AUC by 0.6 mmol·L⁻¹·h, and insulin and C-peptide by 28.7% each.
- Activity breaks work. Regular movement breaks lowered fasting glucose by 0.34 ± 0.37 mmol/L and cut daily glucose variability by about 2%.
- Physiology shifts with life stage. Post-menopausal participants showed a 42% higher two-hour glucose AUC and greater variability — a reminder that "your spike" is not a moral result.
Read that list again. The best-evidenced action to come out of consumer CGM research is go for a walk after you eat — and you do not need a $4,296 subscription to do it. What the sensor buys you is knowing when your personal peak lands, which is genuinely useful information, and which you can learn in about six weeks.
The real difference: a course or a coach
After eight weeks with both, the distinction that mattered wasn't software quality. It was whether you want to learn a skill or delegate it.
Levels is built on the assumption that you'll eventually read your own curves and stop paying. The annotation is better, the export is complete, and the $80 tier exists precisely because the company expects you to graduate. Nutrisense is built on the assumption that you won't, and staffs accordingly — a registered dietitian, weekly check-ins, and an insurance pathway that makes the human part cheap even when the programme isn't.
Levels is a course. Nutrisense is a coach. Both are expensive ways to discover that oats spike you and your friend's don't.
One structural complaint that applies to both: neither will show you sensor error. Consumer CGMs typically report a mean absolute relative difference around 8–10%, which means a "spike" from 95 to 140 mg/dL carries an error bar wide enough to matter. Both apps draw the curve as though it were traced from a lab analyser. It isn't.
Marcus's take
Senior Reviewer — Metabolic · RD · eight weeks on eachI came into this category sceptical and left more sceptical, which is not the arc I expected. Not because the sensors are bad — they're remarkable bits of engineering — but because of what the software does to a normal person's post-meal rise.
Six of the eight metabolic apps I onboarded this year rendered an entirely normal physiological response in alarm red. If you are metabolically healthy, going from 90 to 140 mg/dL after a bowl of rice is your pancreas working, not a wound. An app that colours that red isn't giving you information; it's giving you a mood, and charging a subscription for it.
So my honest recommendation for most people asking "Levels or Nutrisense?" is: neither, at least not at those tiers. Buy two months of an over-the-counter sensor, pair it with the cheapest Levels tier, learn three things — where your personal peak lands, which two meals actually move you, and what a post-meal walk does — then cancel and keep the walk. That's about $200 and it captures most of the available value.
Where I'd genuinely spend the money on Nutrisense: if you have real dysregulation, a diagnosis in the family, or you've tried self-directed change three times and it hasn't held. Accountability is the bottleneck for more people than data is, and a dietitian your insurance partly covers is a much better buy than another dashboard. Just go in knowing you're hiring a person, not a technology.
Who should buy which
Buy Levels if…
- You're analytical and self-directed
- You want complete data export
- You plan to cancel after 2–3 months
- You already have or can buy an OTC sensor
- $80/year is the budget
Buy Nutrisense if…
- Accountability, not data, is your bottleneck
- Your insurance covers the coaching
- You want a registered dietitian reading your curves
- You're new to glucose and want the basics explained
Buy neither if…
- You're metabolically healthy and just curious — buy a sensor for six weeks instead
- You have a history of disordered eating; food scoring is a real risk here
- You want a diagnosis — see a clinician, not an app
A safety note we won't bury. Food-scoring apps and continuous self-surveillance are a poor fit for anyone with a history of disordered eating, and both products are capable of turning an ordinary meal into a failed test. If that's you, this whole category is worth skipping — and no score we publish should override that.
Frequently asked questions
Is Levels or Nutrisense cheaper?
Levels, substantially. Levels ranges from $80/year (app only, bring your own sensor) to $1,999/year for the top tier. Nutrisense starts at $179/month, about $2,148/year. Over 24 months at mid tier that's $998 for Levels versus $4,296 for Nutrisense.
Do I need a prescription for a CGM in 2026?
Not in the US for over-the-counter sensors. Dexcom Stelo (about $89–99/month) and Abbott Lingo (about $49 per 14-day sensor) are sold without a prescription and are aimed at people without diabetes.
Does wearing a CGM improve health if I'm not diabetic?
The evidence is early. A 2025 systematic review of seven studies (~1,127 non-diabetic participants) found CGM "shows promise" for personalising lifestyle change but noted limited evidence on cardiovascular risk factors and none on hard endpoints. The best-supported actions it surfaced — walking before your glucose peak, taking activity breaks — do not require a sensor to perform, only to time precisely.
Can I use Levels with my own sensor?
Yes. Levels' entry tier is explicitly designed for bringing your own sensor, and the app functions without one. That combination is the cheapest legitimate way into the category.
Does insurance cover any of this?
Nutrisense advertises dietitian coaching and stress-management sessions at $0 out of pocket for most members with eligible insurance, which meaningfully changes its value calculation. Levels is HSA/FSA eligible but doesn't bill insurance for coaching, because there isn't any.
How accurate are consumer CGM sensors?
Typical reported mean absolute relative difference (MARD) is around 8–10% against reference measurement, and accuracy degrades at the extremes and in the first hours after insertion. Neither app displays that uncertainty, so treat individual readings as estimates and pay attention to patterns instead.
