Most Noom reviews go wrong in the first paragraph, by comparing it to MyFitnessPal on features. That comparison is not wrong so much as beside the point. Noom is not a calorie tracker that added lessons. It is a behaviour-change programme that added a tracker, and the price only makes sense once you accept that framing.
Everything factual below comes from Noom's own App Store listing or from published research, read on 23 August 2026. No hands-on testing is claimed. SlimAI makes a competing app and appears near the end.
What Noom is selling
Noom, Inc. (com.noom.wlc) describes a product with four parts on its own listing: daily lessons on psychology, habits and behaviour change; food logging with a colour-coded categorisation system; optional 1:1 coaching; and, through Noom Med, access to GLP-1 medications such as Ozempic, Wegovy, Zepbound and Mounjaro for eligible users, with "100% online access to doctors & health coaches".
The proposition is that knowing what to eat was never your problem. Noom sells the layer above the diary: why you eat what you eat, and someone checking whether you did.
What it does well
The scale of adoption is real. 4.7 stars from 870,570 US ratings as of 23 August 2026 puts Noom among the most-rated health products on the store. Whatever criticism follows, this is not a fringe product with a marketing budget.
The curriculum is a genuine mechanism, not filler. The research on tracking is unambiguous that frequency predicts outcomes — participants who logged on 70.2% of days lost 2.19% of body weight against 1.54% for a sample logging about half the time (Payne et al., 2022, cited below). Anything that reliably increases how often you log is doing real work. A daily lesson and a coach who notices when you stop are two of the few things that demonstrably do.
Colour-coding is a defensible simplification. Sorting foods by calorie density rather than asking beginners to internalise gram-level macros lowers the entry barrier. Nutritionally it is coarse. Behaviourally it is well-judged.
The GLP-1 arm is an honest answer to where the market went. Rather than pretending medication is not reshaping this category, Noom built a supervised pathway into it. Whether you want that is personal; that it exists under clinical oversight rather than being ignored is to the company's credit.
Noom publishes an outcome figure. Its listing cites an average of 15.5 lb in 16 weeks. That is a company-published number and should be weighed as one — but most competitors publish nothing at all, and a stated figure can at least be argued with.
Where it gets harder
You cannot find out the price without going through checkout
As of 23 August 2026, Noom's App Store listing shows the in-app purchases as:
| Listed product | Price |
|---|---|
| Noom Program | $44.99 |
| Noom Program | $98.99 |
| Noom Program | $129.99 |
| Noom Program | $159.99 |
| Noom Program | $199.99 |
| Noom Pro | $9.99 |
Plus Noom Med, described as starting at $69/month.
Five prices under one product name, spanning a 4.4× range, with no billing period attached to any of them on the listing. Some of that is legitimately different durations. The practical consequence is unchanged: the price you are quoted depends on the funnel you entered through and the offer you were served, so no review can tell you what Noom costs. Read the terms on the confirmation screen, not the marketing page.
The trial is where most complaints originate
Noom's trial structure has been the subject of sustained public criticism, and the pattern is consistent: users report expecting a low introductory charge and encountering a larger commitment. Nothing here is a claim about Noom's current terms specifically — those change — but it is the single thing worth reading carefully before entering card details. Note the renewal date and the amount.
If you do not use the coach, you are paying for a diary
This is the honest core of the value question. The curriculum and the coaching are what justify programme pricing over app pricing. If the lessons go unread and the coach messages go unanswered while you log your food every day, you are paying several times over for the cheapest part of the product. That is not a flaw in Noom. It is a mismatch between the buyer and the thing bought — and it is by far the most common one.
The tracker underneath is ordinary
Noom's logging is competent and unremarkable. It inherits the same constraint every tracker does: a meta-analysis of 14 validation studies across 12 dietary-record apps found all of them underestimated energy intake, pooled at −202 kcal/day, mostly attributable to the food database rather than the app (Zhang et al., 2021). You are not buying Noom for logging accuracy, and it would be strange to.
Who should use Noom
A real recommendation, not a setup for the alternatives section.
- You know what to do and consistently do not do it. This is the specific failure Noom is engineered against, and no calorie tracker on the market addresses it.
- Accountability to a person changes your behaviour. If a coach noticing your absence is what gets you back, that is worth money and only Noom's category sells it.
- You are early and overwhelmed. Colour-coded categories are a gentler on-ramp than macro targets.
- You are considering GLP-1 medication and want supervision around it. A structured programme with clinical access is a better route than the alternatives people otherwise find.
Who might want something else
- You already run a deficit competently. You are buying the part you do not need.
- Price certainty matters to you.
- You want nutrient depth. The colour system is behavioural, not nutritional.
- You want body composition data. Noom tracks weight; weight alone cannot tell you whether you are losing fat or lean mass.
Alternatives worth considering
Each answers a different reason for leaving.
MyFitnessPal — for the largest food database and years of transferable diary history, at ordinary app pricing. Barcode and meal scan sit behind Premium; the full review is here.
Cronometer — for verified nutrient data. Gold is listed at $10.99/month or $59.99/year, and its free tier is unusually capable, making long-term unpaid use genuinely viable.
SlimAI Calorie Tracker — for the calculating half of what a coach does, at app pricing. Of the four things a coach does — tell you where you are heading, why, what to do next, and hold you to it — SlimAI's AI Coach does the first three every week from your own data, with a written report each Monday, and does not pretend to do the fourth. It also adds AI Body Assessment, a body fat estimate from two photos, which answers a question the scale cannot. Where SlimAI does not compete: there is no human coach, no curriculum, and no medication pathway. If accountability is your gap, this is not the fix. Current pricing here.
