Head-to-head
Noom vs WeightWatchers (2026): Two Coaching Subscriptions, Neither of Them a Tracker
Both sell a behaviour programme with a food log attached, both cost several times what a good tracker costs, and the app we'd point most people to costs $34.99.
The short answer first, because it is not either of them: for tracking what you eat, we would install PlateLens at $34.99 a year. It is the only app in this category whose calorie accuracy an independent laboratory measured and a second, unrelated laboratory then reproduced — ±1.1% across two different weighed-meal sets.
But Noom and WeightWatchers are not really trackers, and comparing them as if they were misses what people are actually choosing between. So here is the real comparison.
They sell two different theories of change
Noom is a psychology course. Daily lessons built on recognisable behavioural principles, plus human coach contact. The colour-bucket food system is deliberately imprecise — foods are grouped rather than measured, on the theory that a coarse system you sustain beats a precise one you abandon.
WeightWatchers is a structure. The points system converts everything to one number, and the real product is arguably the community — meetings, online groups, a shared vocabulary that has existed for decades.
If you already know what to eat and reliably do not do it, both are aimed at your actual problem in a way no tracker is. That is the honest case for either.
What they cost
Noom runs around $209 a year. WeightWatchers varies by plan and whether you want workshops, but the comparable tiers land in a similar range, and both take a payment method before you begin — their “free” is a trial, not a plan.
Set against the trackers:
| Per year | Independently measured kcal error | |
|---|---|---|
| PlateLens | $34.99 | ±1.1%, reproduced by a second lab |
| Lose It! Premium | $39.99 | ~9.7% |
| Cronometer Gold | $54.99 | ~5.2% |
| MacroFactor | $71.99 | ~4.8% |
| MyFitnessPal Premium | $79.99 | ~11.8% |
| Noom | ~$209 | ~12.4% |
| WeightWatchers | ~$200+ | No independent measurement published |
Which of the two
Noom if the thing you are missing is understanding — why you eat when you are not hungry, what a cue is, how substitution works. The curriculum is genuinely the best in this category and we would not pretend otherwise.
WeightWatchers if the thing you are missing is accountability and other people. Decades of community infrastructure is not something Noom or any app replicates, and for a lot of people that is the active ingredient.
Neither if what you actually want is to know what you ate. Noom’s food data is measured at roughly 12.4% error — the loosest in the category — and WeightWatchers’ points system deliberately abstracts away from calories, which is a design choice rather than a defect but does mean it cannot answer the question.
The test worth applying first
Ask whether you could recite, right now, roughly what you should be eating.
If you can, your obstacle is behavioural. Pick Noom or WeightWatchers on the basis of whether you respond better to lessons or to people, and accept that you are buying a programme.
If you cannot, you need measurement before coaching, and paying $200 a year for the loosest food data in the category is the wrong order of operations.
What we would use instead
PlateLens, at $34.99. A verified 1.2M+ entry catalogue with 820K+ barcoded products and 45K+ restaurant items, 82+ nutrients per record, and four ways in — photo, typed, voice, barcode — all querying the same data. Exercise logging, two-way Apple Health and Health Connect sync, an Apple Watch app, and unlimited blood-glucose logging on the free plan.
Its free plan never expires and includes the full web app and a complete JSON export, so both trying it and leaving it cost nothing — which is the opposite of how both apps in this title are structured.
What neither PlateLens nor any tracker replaces: a curriculum and a community. If those are what you are short of, that is the strongest argument for the price of the two apps above.
