The best weight tracker apps
Starting priceFree
Free planYes
MyFitnessPal is the default answer for a reason: it connects the two habits that matter, what you eat and what you weigh. The food database is enormous, with barcode scanning, meal photo logging and voice entry, and your weigh-ins plot on the same dashboard as your calories and macros. It supports GLP-1 medication tracking, step syncing from 40+ apps and devices, and 2,000+ in-app recipes. With over 280 million users, the community and content depth are unmatched.
The free tier is genuinely usable but ad-supported, and features like the AI nutrition coach sit behind Premium at $19.99 per month or $79.99 per year. If your weight goal is really a food goal, this is the app. If you only want to log weigh-ins, the simpler tools below do it with less noise.
What we like- 20.5 million foods in the database
- Weight, measurements and progress photos in one place
- Syncs with 40+ apps and devices
Watch out for- Free tier shows ads and locks some features
- Premium costs $19.99 per month or $79.99 per year

Lose It!
Best for: simple calorie budgets with weight tracking
Visit loseit.com
Starting priceFree
Free planYes
Lose It! takes a simpler approach than MyFitnessPal: instead of drowning you in data, it assigns a personalized daily calorie budget and makes staying inside it fast. Snap a photo of your plate, scan a barcode or just say what you ate. Your weight log plots against that budget, with patterns and reports showing which behaviors move the scale. It has been around since 2008 and holds a 4.8 rating across hundreds of thousands of reviews.
The free download covers the core tracking, with an optional premium subscription adding the deeper features. Premium pricing runs about $39.99 per year in most listings. For people who find MyFitnessPal overwhelming, Lose It!'s budget-first design is easier to stick with, and adherence is what moves the scale.
What we like- Personalized daily calorie budget that adapts
- Photo and voice food logging
- Weight trends with goal projections
Watch out for- Nutrition detail is thinner than Cronometer
- Premium needed for the full feature set

Free planYes
Happy Scale solves the psychological problem of weighing yourself: daily numbers bounce, and the bounce demoralizes. It applies a moving average to your weigh-ins, showing the true trend line underneath the water-weight noise, and breaks your goal into small milestones so you are always close to a win. It predicts your goal date from your actual rate of loss and celebrates the small victories.
It is free and does one thing well. There is no food logging, no exercise tracking and no social feed, which is either a relief or a dealbreaker depending on your style. The iOS app is the flagship experience. If you already track food elsewhere and just want the best free weight tracking app for the scale itself, this is it.
What we like- Moving-average smoothing removes daily noise
- Milestone tracking keeps motivation up
- Completely free with no upsell pressure
Watch out for- IOS focused with limited Android options
- No food logging, weight only
Starting priceFree
Free planYes
Cronometer is the weight tracker for people who read nutrition labels for fun. Where other apps count calories, Cronometer tracks over 80 micronutrients, so you can see whether your diet actually nourishes you while you lose weight. The weight section supports custom biometrics, body measurements and progress charts, and the food database is curated for accuracy rather than size. Health professionals recommend it for that reason.
The free tier is generous, with Gold at $10.99 per month or $59.99 per year adding fasting timers, custom charts and priority support. The trade-off is warmth: the interface is precise and clinical where MyFitnessPal is encouraging. If your goal includes understanding your nutrition deeply, Cronometer is unmatched. If you want cheerleading, look elsewhere.
What we like- Tracks 80+ micronutrients, not just calories
- Weight charts with custom biometric tracking
- Respected data accuracy
Watch out for- The interface is clinical rather than friendly
- Gold costs $10.99 per month or $59.99 per year
Starting priceFree
Free planYes
FatSecret is the veteran free option that refuses to paywall the basics. Food diary, weight chart, exercise log, barcode scanner and recipe collection are all free, supported by a large community running challenges and sharing journals. The restaurant database is strong, which helps real-world logging, and the weight tracker covers the essentials with trend views.
There is a premium tier in the app stores, but most users never need it, which is the point. The interface has not kept pace with newer apps, and the design feels a decade old in places. But if you want the best free weight tracking app with food logging included and no subscription pressure at all, FatSecret's free tier is hard to argue with.
What we like- Completely free core tracking
- Large food database with restaurant items
- Active community and challenges
Watch out for- The interface feels dated
- Premium tier adds little for most users
Starting priceFree
Free planYes
Yazio wraps weight tracking in guided structure. Instead of handing you a blank diary, it offers plans for calorie counting, intermittent fasting and specific diets, with meal plans, recipes and a fasting timer built in. The interface is modern and pleasant, the food database covers the essentials, and the weight chart tracks your progress against the plan's targets. It is particularly popular in Europe.
The free tier covers basic tracking, while Pro at around $39.99 per year opens up the full plans, recipes and advanced stats. The guided approach suits people who want to be told what to do rather than figure it out. If you prefer open-ended tracking, MyFitnessPal or Cronometer give you more freedom.
What we like- Structured plans for weight loss and fasting
- Clean modern interface
- Strong recipe and meal plan content
Watch out for- Pro features cost about $39.99 per year
- Some plans push upsells
Starting priceFree
Free planYes
Fitbit's weight tracking makes sense if you already live in its ecosystem. Log your weight manually or step on an Aria smart scale and it syncs automatically, landing in the same dashboard as your steps, sleep, heart rate and workouts. Seeing weight alongside activity and sleep reveals patterns, like the weeks your sleep collapses and your weight follows, that a standalone scale app cannot show.
The Fitbit app is free, with Premium at $9.99 per month adding deeper insights, guided programs and a readiness score. Without a Fitbit device or scale, it is just another manual log, and there are better ones. With the hardware, it is the most complete picture of your health in one place.
What we like- Weight syncs with steps, sleep and heart rate in one dashboard
- Aria scale integration
- Huge existing user base
Watch out for- The best insights need Premium at $9.99 per month
- App future is tied to Google's plans
Starting priceFree
Free planYes
MyNetDiary positions itself as the premium-feeling tracker, and the free tier backs it up: no ads, which is rare in this category. It offers AI-powered diet guidance, meal planning and a weight tracker with trend analysis, plus specialized plans for diabetes management and other health conditions. The interface is polished and the guidance feels personal rather than generic.
Premium at $59.99 per year adds the full coaching features and deeper analysis. The food database is smaller than MyFitnessPal's 20-million-item giant, though it covers common foods well. If ads in free apps bother you and you want guidance without a subscription, MyNetDiary's free tier is the best combination on this list.
What we like- Free tier has no ads
- AI diet guidance and meal planning
- Strong diabetes and health-condition plans
Watch out for- Premium costs $59.99 per year
- Smaller food database than MyFitnessPal
Starting priceFree
Free planYes
Monitor Your Weight is the old-school Android weight tracker that has quietly served over 10 million installs. Its standout feature is multiple profiles: track your own weight alongside family members, each with separate goals and charts. It suggests your ideal weight from your age, height, frame and gender, estimates the timeline to reach it, and plots full-screen progress graphs with statistics like average weekly loss.
It is free with no subscription tier, which is increasingly rare. The limits are clear: Android only, a dated interface, and no food or exercise logging. But for pure weight monitoring, especially for a household sharing one app, it does the job with zero cost and zero upsell. Sometimes the simplest tool is the right one.
What we like- Track multiple profiles, great for families
- Ideal weight and timeline suggestions
- Completely free on Android
Watch out for- Android only
- Dated design with no food logging
What to look for in a weight tracker
The scale lies to you daily, and a good app knows it. Look for trend smoothing or moving averages, like Happy Scale's, that show the real direction under the noise. Check whether it tracks what drives weight: food logging in MyFitnessPal and Lose It!, nutrition depth in Cronometer, or activity and sleep in Fitbit. A weight number without context is just a number.
Free is genuinely enough here
This is one category where free tiers are excellent. Happy Scale, FatSecret, Monitor Your Weight and MyNetDiary's ad-free tier cost nothing and cover the core job. Premium upgrades add coaching, deeper analysis and plan content, worth it if you use them, unnecessary if you just weigh in daily. Start free for a month and only pay for features you have actually missed.
Pick the habit you will keep
The best weight tracking app is the one you open every morning. If you already log food, add weight there. If you wear a Fitbit, log weight there. If you hate food logging, use a pure scale app and skip the guilt. Weigh daily or weekly, same conditions, and let the trend line do the talking. Consistency beats features every time.
How we chose
We focused on apps with a usable free tier for logging weight, not trials that expire. For each app we checked the vendor's site and app store listings for pricing, free plan details and features, then cross-checked against public reviews on the App Store, Google Play and Reddit. We included both pure weight loggers and broader health apps with strong weight tracking, and excluded discontinued apps and single-purpose BMI calculators. Prices were checked in October 2026 and change often, so confirm in the app before relying on them.
Frequently asked questions
What is the best free weight tracking app?
Happy Scale is the best pure weight logger, with trend smoothing that keeps you motivated, and it is completely free. If you want food logging too, FatSecret and MyFitnessPal have excellent free tiers. MyNetDiary's free tier stands out for having no ads. For families sharing one app, Monitor Your Weight's free multi-profile tracking is unique.
Should I weigh myself every day?
Daily weighing works well if your app smooths the trend, which is exactly what Happy Scale and most of these apps do. The daily data makes the trend line more accurate, and you learn to ignore the noise. If daily weigh-ins stress you out, weekly works fine too. What matters is consistency: same scale, same time of day, same conditions.
Do weight tracker apps actually help you lose weight?
They help the way any measurement helps: what gets tracked gets managed. Studies consistently link regular self-weighing with better weight outcomes, and apps make the habit stick by visualizing progress. The apps that pair weight with food logging, like MyFitnessPal and Lose It!, address the cause as well as the number, which is why they dominate this category.
Can I track my family's weight in one app?
Monitor Your Weight supports multiple profiles on Android, which is ideal for households. Most other apps are single-user, tied to one account. If everyone in the family wants tracking, separate free accounts on Happy Scale or FatSecret work well, or use Fitbit with multiple Aria scale users.
Which app is best with a Fitbit device?
The Fitbit app itself, since weight syncs into the same dashboard as steps, sleep and heart rate. An Aria smart scale logs weight automatically. Third-party apps like MyFitnessPal also sync with Fitbit, so you can log food in one and see everything in the other. Pick based on where you want your main dashboard to live.
Is my weight data private?
Weight data is health data, so read the privacy policy. Most of these apps store your data in the cloud and use it for product improvement; free tiers may show ads based on app usage. MyNetDiary's ad-free free tier is the most privacy-comfortable free option here. If this matters to you, prefer apps with clear data policies and export options.
