Choose Noom if you want to change habits through daily psychology lessons and are happy to keep counting calories with a green, yellow and orange food guide. Choose WeightWatchers if you would rather track a single Points number, with 350+ ZeroPoint foods, a barcode scanner, live coach-led sessions and a big member community.
Both are paid programs with GLP-1 options, and both can suit people well. The rest of this page compares price, tracking style, coaching and medication support so you can pick the one that fits how you actually eat.
Disclosure: this page is written by the Calo AI Team. Calo AI is our own app, and we have no link to Noom or WeightWatchers. Every Noom and WeightWatchers fact below comes from their own websites and app store listings, checked on 2 November 2026. Prices and offers change often, so treat them as a snapshot.

How much does Noom cost compared with WeightWatchers?
Neither app has a free plan with the full program. Both are free to download and then sell membership.
Noom. Its App Store listing says Noom Weight plans are “as low as $17 a month”, based on a $209 annual auto-renewing web plan, before tax. Noom Med plans “start at $39 a month”, based on the first month’s fee only and not including medication. The US in-app purchases, all named “Noom Program”, run from $44.99 to $199.99, without saying what period each covers.
WeightWatchers. Its US plans page on 2 November 2026 showed introductory offers rather than regular prices:
- Core: $10 a month for the first 12 months on a 12 month plan.
- Core+: $20 a month for the first 12 months, in participating areas only.
- Med+: $25 a month for the first two months, then $74 a month for the rest of a 12 month plan. The page says GLP-1 medication costs are not included.
The page said the Core and Core+ offers end on 3 November 2026 and that plans auto-renew for another 12 months “at the regular price”, which it did not show. The US App Store lists monthly plan items from $19.99 to $24.99 and a “WW Digital 6-month” item at $108.99. So the honest answer to “which is cheaper” is: whichever has the better offer on the day you join, and check the renewal price before you pay.
What do they cost in Canada and Australia?
| Country | Noom App Store purchases | WeightWatchers |
|---|---|---|
| Canada | CA$58.99 to CA$259.99 | Website: “as low as $9/mo”; App Store items CA$22.99 to CA$249.99 |
| Australia | A$64.99 to A$309.99 | Website: “as low as $12.60/mo”; App Store items A$34.99 to A$499.99 |
The listings do not say which billing period each Noom price covers, and the WeightWatchers website prices are starting offers. Your own checkout screen is the price that applies.
Is Noom’s colour system easier than WeightWatchers Points?
They feel quite different day to day.
Noom still counts calories. On top, it sorts foods into green, yellow and orange, mainly by calorie density, which is calories per gram. Its support page explains the system: foods with a low calorie density are green and foods with a high calorie density are orange, with yellow in between. The idea is to nudge you towards foods that fill you up for fewer calories.
WeightWatchers replaces calories with one Points number per food. Its US site lists 350+ ZeroPoint foods that you do not need to track, and its app also shows protein, fibre, carbs and calories. Many members like not having to weigh fruit or count every egg.
A simple way to choose:
- You like seeing real numbers and want to understand energy balance: Noom, or plain calorie counting. Our guide to the calorie deficit explains the maths.
- You want fewer decisions and like a shortcut: WeightWatchers Points with ZeroPoint foods.
Which has better coaching and support?
Noom puts lessons first. The listing promises daily lessons on habits and behaviour change, “supportive communities” and optional 1:1 coaching. If the psychology side is why you are interested, this is Noom’s strongest point.
WeightWatchers leans on people and community. Its listing describes live sessions led by weight loss coaches, 1:1 meal planning support from registered dietitians (which its footnote says can cost as little as $0 with qualified insurance, with copays possible) and a members’ social network. It also has a menopause program and Support for Diabetes on its US site.
If you want a human to talk to and a group to belong to, WeightWatchers offers more of that. If you prefer reading short lessons on your own schedule, Noom fits better.
Which is better if you take a GLP-1 medication?
Both now build programs around GLP-1 medications, and both are clear that eligibility is decided by a clinician.
- Noom Med offers access to Ozempic, Wegovy, Zepbound or Mounjaro if eligible, or Noom’s own GLP-1Rx options, with online access to doctors and health coaches and a “GLP-1 Companion Program with Muscle Defense”. Its footnotes say 7 day delivery applies only to compounded medications, which are not reviewed by the FDA for safety, efficacy or quality.
- WeightWatchers offers Med+ for clinical care and prescriptions if eligible, plus a GLP-1 Success Program with dose tracking, nutrition and side-effect management.
Whichever you choose, protein matters more when appetite drops. Our guide to protein on GLP-1 medications covers targets, and our GLP-1 food tracker app page compares tracking options. Medication choices belong with your prescriber, not an app.
Who should pick Noom, and who should pick WeightWatchers?
Noom is likely the better fit if you:
- Want daily lessons on the psychology of eating.
- Are comfortable tracking calories and like a colour guide on top.
- Want built-in workout, stretching and meditation classes.
- Want intermittent fasting support inside the same app.
WeightWatchers is likely the better fit if you:
- Prefer Points and ZeroPoint foods over counting calories.
- Want a barcode scanner, restaurant entries and a big recipe library.
- Want live coach-led sessions, dietitian support or a community.
- Use an iPad or Apple Watch as well as a phone.
WeightWatchers says it has 60+ years of helping members, and both apps are rated 4.7 or higher on the US App Store.
What if you only want the tracking part?
Some people sign up for Noom or WeightWatchers mainly to log meals and see a daily number. If that is you, a free calorie tracker may be enough, and you can learn the habit side from free reading. Our free Noom alternative and WeightWatchers alternative app pages cover that route in more detail.
Calo AI is one free option. It runs on Android, with a web app at caloai.fit/app for iPhone, iPad, Mac and PC. Every feature is free: AI photo meal scanning, voice and text logging, personalised calorie and protein targets, an AI nutrition coach, meal plans using dishes from your own country’s cuisine and an intermittent fasting timer. The free version shows ads, including one before each meal scan, and there is a short wait between AI coach messages. Premium removes the ads and waiting but adds no features.
To be fair about what you give up: Calo AI has no psychology lessons, no Points, no human coaches, no community and no medication program, and it has no barcode scanner or native iPhone app. Photo results are estimates, and portion size is the hardest part, so describing the dish helps. If you want to try it, use the web app free or get it on Google Play. You can also start with our calorie deficit calculator to find a sensible target.
A note on safety: no app or program can promise a set amount of weight loss, and real results vary. If you are pregnant or breastfeeding, under 18, or have diabetes, PCOS, kidney disease or a history of eating disorders, speak to a doctor or registered dietitian before starting any weight loss program. Do not go below 1,200 kcal a day without medical supervision.
