The short answer

Lifesum is a freemium food tracker with diet programmes and meal plans, suited to people who want to log meals and follow an eating style like keto or Mediterranean. WeightWatchers is a paid weight-loss program built on its Points system, with coaching, community and, for eligible US members, GLP-1 medical care. The biggest difference: Lifesum is a tracking app, WeightWatchers is a full program.

Lifesum or WeightWatchers: our take

Lifesum focuses on everyday food tracking and habit building. Meals can be logged by photo, voice, text or barcode, there are trackers for water, fruit and vegetables, and the app breaks down protein, carbs, fats, sugar and fibre while giving each day a rating. Its diet programmes cover high-protein, Mediterranean, fasting and keto, with recipes to match. WeightWatchers takes a different approach: the Points system turns nutrition data into one number per food, so members can eat anything within a daily budget, and the budget can be adjusted for situations such as diabetes or breastfeeding.

Pricing differs in structure. Lifesum's basic tracking is free, though most meal plans, recipes and detailed nutrient insights need Premium. WeightWatchers has no free plan at all; it sells three tiers, Core, Core+ and Med+, and frequent introductory offers make its real monthly price hard to compare. Med+ adds prescriptions for GLP-1 medications through an affiliated medical group, but it is US-focused and requires eligibility.

Both run on iPhone and Android. WeightWatchers also has a web account and in-person workshops in some areas, while Lifesum has no full web app for logging on a computer. Lifesum syncs with Apple Watch and Samsung Galaxy Watch.

Lifesum fits people who want a friendly tracker with structured eating plans and would like to start free. WeightWatchers fits people who want a points-based program with coaching and community accountability, or who are in the US and interested in medically supported weight loss.

What is Lifesum?

Lifesum is a healthy-eating app from Stockholm-based Lifesum AB, available for iPhone and Android. It tracks food and exercise and gives each day a rating, so the focus is on building better habits rather than only counting calories. You can log meals by photo, voice, typing, barcode scan or quick-add, follow water, fruit and vegetable trackers, and see a breakdown of protein, carbs, fats, sugar and fibre. A big part of the app is its diet programmes and meal plans, which cover approaches such as high-protein weight loss, Mediterranean, fasting and keto, with recipes to match. It syncs with Apple Health and wearables like Apple Watch and Samsung Galaxy Watch. Basic tracking is free, while the diet plans, detailed nutrient insights and most recipes need a Premium subscription. There is also a Lifesum for Work programme for employers.

What is WeightWatchers?

WeightWatchers (also styled WW) has run weight-loss programs for more than 60 years and now delivers them mainly through its app. The core idea is the Points system, which turns nutrition data into a single number per food so you can eat what you like within a daily budget; it can be adjusted for situations like diabetes or breastfeeding. Plans range from app-only Core, to Core+ with extra coaching and workshops, to Med+, a clinical tier where eligible members get prescriptions for GLP-1 medications through an affiliated medical group alongside behavioural support. It suits people who want a structured, flexible program and like community accountability. Everything is subscription based with no free tier, and frequent introductory offers make the true monthly price hard to compare. The app runs on iPhone and Android with a web account, and in-person workshops are available in some areas.
