We compared official feature pages, pricing pages, app store listings, privacy policies and public reviews to build this list for best weight tracker app. Every option below exists and works today, and each one earns its place for a different kind of reader.

Ideal for: Weight trends without daily noise

Here is the short version. Happy Scale suits readers who get discouraged by daily weight swings, because its trend line shows the direction over weeks rather than one noisy day. That view helps you stay calm after a high reading. It fits readers who want weight trends without daily noise, and its published feature set matches that promise rather than trying to cover every possible use case at once. When we weighed it against the rest of this list, the balance of price, scope and support stood out for that group. The price picture is see website, with a free plan status of yes. Its focus is weight only, so readers who also want food or exercise tracking will need a second app for those jobs. Before you sign up, check the current plan limits on the official site, because caps on users, usage or features are where most buyers get surprised after the first month.

Ideal for: Food and weight tracking together

Start here if you want the safe default. Lose It combines food logging with weight tracking, which helps readers who want to see the link between eating and weight change. Its barcode scanner and food database make logging faster than manual entry. It fits readers who want food and weight tracking together, and its published feature set matches that promise rather than trying to cover every possible use case at once. When we weighed it against the rest of this list, the balance of price, scope and support stood out for that group. The price picture is see website, with a free plan status of yes. Food logging still takes daily effort, and full features need a paid plan, so check whether you will log consistently before paying. Before you sign up, check the current plan limits on the official site, because caps on users, usage or features are where most buyers get surprised after the first month.

Ideal for: Largest food database for tracking

This one suits a specific kind of reader. MyFitnessPal has the largest food database in this list, which makes logging packaged and restaurant foods easier. Its weight trends and exercise links cover the basics for most readers. It fits readers who want largest food database for tracking, and its published feature set matches that promise rather than trying to cover every possible use case at once. When we weighed it against the rest of this list, the balance of price, scope and support stood out for that group. The price picture is see website, with a free plan status of yes. The free tier has ads, and some features now need premium, so check which tools you actually use before upgrading. Before you sign up, check the current plan limits on the official site, because caps on users, usage or features are where most buyers get surprised after the first month.

Ideal for: Structured programme with support
Consider this if the top picks do not fit. WeightWatchers suits readers who want structure and support, with a points system, workshops and community beside app tracking. That support helps people who struggle alone with a simple tracker. It fits readers who want structured programme with support, and its published feature set matches that promise rather than trying to cover every possible use case at once. When we weighed it against the rest of this list, the balance of price, scope and support stood out for that group. The price picture is see website, with a free plan status of no. The subscription cost is ongoing, and the points system takes learning, so trial it for a month before committing to a longer plan. Before you sign up, check the current plan limits on the official site, because caps on users, usage or features are where most buyers get surprised after the first month.

Ideal for: Weight tracking with activity data
A strong option for a narrower need. Fitbit suits readers who already track activity, because weight data sits beside steps, sleep and heart rate in one app. Scale sync makes logging automatic for Fitbit scale owners. It fits readers who want weight tracking with activity data, and its published feature set matches that promise rather than trying to cover every possible use case at once. When we weighed it against the rest of this list, the balance of price, scope and support stood out for that group. The price picture is see website, with a free plan status of yes. Its value is highest with Fitbit devices, and deeper insights need premium, so readers without Fitbit hardware may prefer a standalone tracker. Before you sign up, check the current plan limits on the official site, because caps on users, usage or features are where most buyers get surprised after the first month.

Ideal for: Weight data on Apple devices
Worth a close look before you decide. Apple Health is the simplest pick for iPhone owners, because weight data from many apps and scales flows into one place without a new account. Its trends are clear, though basic. It fits readers who want weight data on apple devices, and its published feature set matches that promise rather than trying to cover every possible use case at once. When we weighed it against the rest of this list, the balance of price, scope and support stood out for that group. The price picture is free, with a free plan status of yes. It is Apple only, and its weight features are simpler than specialist trackers, so serious goal setters may want Happy Scale or Lose It alongside it. Before you sign up, check the current plan limits on the official site, because caps on users, usage or features are where most buyers get surprised after the first month.

Ideal for: Smart scale weight tracking
This belongs on the shortlist for a reason. Withings suits readers who want automatic logging, because its smart scales send weight and body composition to the app without manual entry. That automation removes the most common reason tracking stops. It fits readers who want smart scale weight tracking, and its published feature set matches that promise rather than trying to cover every possible use case at once. When we weighed it against the rest of this list, the balance of price, scope and support stood out for that group. The price picture is see website, with a free plan status of yes. The full value needs a Withings scale, which is an extra cost, so check whether you already own one before choosing it for weight alone. Before you sign up, check the current plan limits on the official site, because caps on users, usage or features are where most buyers get surprised after the first month.

Ideal for: Behaviour and habit coaching
Do not overlook this one. Noom suits readers who want coaching and habit lessons beside weight tracking, with daily lessons that address eating habits and mindset. That behavioural focus is different from a pure tracker. It fits readers who want behaviour and habit coaching, and its published feature set matches that promise rather than trying to cover every possible use case at once. When we weighed it against the rest of this list, the balance of price, scope and support stood out for that group. The price picture is see website, with a free plan status of free trial. The subscription cost is higher than a simple tracker, and its coaching style does not suit everyone, so trial it before a long plan. Before you sign up, check the current plan limits on the official site, because caps on users, usage or features are where most buyers get surprised after the first month.
We started from official feature pages and pricing pages, then checked app store listings, privacy policies and public reviews to confirm each product still works and still fits the topic. Products that could not be verified, or that only partly matched the topic, were left out, even when they were well known. We favoured a mix of established leaders and strong smaller options, and we weighted price transparency, a usable free tier or trial, and honest limits more heavily than marketing claims. No product on this list paid for its place, and our pick for most people is the one we would suggest to a friend with ordinary needs and an ordinary budget.
Start with what makes you stop tracking. If daily swings discourage you, pick a trend app such as Happy Scale. If manual logging is the problem, pick a smart scale app such as Withings or Fitbit. If food is your main question, pick Lose It or MyFitnessPal for food databases. Next, check whether you need support: a structured programme such as WeightWatchers or Noom helps some readers, while others prefer a simple free tracker. Set a realistic weighing habit, such as three times a week, rather than daily if daily weighing stresses you. This is not medical advice, and if you have a health condition, talk to a clinician before starting a weight plan. Also check privacy and data export, because weight data is sensitive. A good tracker lets you export your history and delete your account cleanly. Avoid apps that promise rapid results or push extreme plans, and focus on a steady trend over weeks rather than a single day reading. The best weight tracker is the one you still open in three months, so pick the simplest option that fits your habit.
Happy Scale is best for trends, Lose It and MyFitnessPal are best for food plus weight, and Withings is best for automatic scale sync. The right pick depends on whether food, activity or simplicity matters most.
Happy Scale, Lose It, MyFitnessPal and Apple Health offer free tiers for weight tracking. Free plans limit some food and insight features, so check what you need before paying.
For free weight-only tracking, Happy Scale and Apple Health are strong picks. For free food plus weight tracking, Lose It and MyFitnessPal cover more ground.
Daily weighing works for some people, especially with a trend app that smooths swings, but it stresses others. Weighing three times a week and watching the trend is a calmer habit for many readers.
Yes, smart scales remove manual logging, which helps consistency. Withings and Fitbit scales sync automatically, though the scale itself is an extra cost.
