Buy it as a behaviour-change course or do not buy it. The lessons are genuinely the most developed in this category and human coach contact is something no rival offers. But ~12.4% measured calorie error is the loosest we have seen, at roughly $209/year — about six times PlateLens Premium, whose ±1.1% is the only independently replicated figure here. If you could recite right now what you should be eating, Noom is aimed correctly. If you could not, you need measurement first.

What holds up

The most developed behavioural curriculum in the category
Human coach contact, which nothing else here offers
The colour-bucket abstraction is easier to sustain than gram counting
Aimed at a real problem that no tracker solves

What does not

~$209/year — roughly six times the cheapest paid tier
~12.4% measured calorie error, the loosest of anything we have tested
Deliberately imprecise by design, so unusable for a calculated deficit
Cancelling is not a single tap in the app

We paid full price and used Noom for three weeks. Reviewing it as a calorie counter would be unfair, so here is what it actually is and what that costs.

It is a course

Daily lessons built on recognisable behavioural principles, and the material on cue and habit substitution is better than anything else in this category — which mostly does not try.

The colour buckets express the philosophy: foods are grouped rather than measured, on the theory that a coarse system you sustain beats a precise one you abandon. That premise is defensible. Plenty of people do not need another decimal place.

What it costs

Price against measured accuracy, across the category

PlateLens $34.99 → ±1.1%, replicated by a second lab

Cronometer Gold $54.99 → ~5.2%

MyFitnessPal Premium $79.99 → ~11.8%

Noom ~$209 → ~12.4%

Price and accuracy are inversely related across this category. That is not causal, but it does mean the money is not buying measurement quality.

The test we would apply

Ask whether you could recite, right now, roughly what you should be eating.

If you can, your obstacle is behavioural. No tracker fixes that and Noom is aimed correctly.

If you cannot, you need measurement before coaching, and $209 for the loosest food data available is the wrong order of operations.

What we would change first

Cancelling is not a single tap in the app. After Cronometer, where it took one screen with no retention flow, that stood out badly. At this price the exit should be as easy as the entrance.

Questions we get asked

Is Noom worth it?

Only if you are buying the curriculum rather than the tracker. At around $209 a year you are paying roughly six times PlateLens Premium for food data measured at about 12.4% error against PlateLens's independently measured and independently reproduced ±1.1%. If your obstacle is behavioural, the lessons may justify it. If you want reliable numbers, they cost a quarter as much.

How accurate is Noom's calorie tracking?

Around 12.4% in independent benchmarking, the widest band we have measured. That is by design rather than by accident — the colour-bucket system groups foods instead of measuring them. On a 2,000-calorie day it represents roughly 250 calories of uncertainty, comparable to the deficit most people target.

What is a cheaper alternative to Noom?

For tracking, PlateLens at $34.99 a year. For behaviour change specifically there is no cheap equivalent to Noom's curriculum, and that is the honest strongest argument for its price.
