Best Free Weight Loss Apps in 2026: 9 Apps Compared

FatSecret is our pick for the most complete free tracker because it keeps the everyday tools free. You can scan barcodes, log meals, track macros, and build recipes without paying, which is now rare among large tracking apps. Its community and food diary also help users who want support and history in one place.

The interface feels functional rather than sleek, and ads appear on the free plan. Some users may also find its food entries less curated than Cronometer. If you want the most tracking for zero cost and you can live with ads, FatSecret is the best free starting point.

Cronometer suits users who care about nutrients, not just calories. Its free plan tracks a wide range of vitamins and minerals, lets you set custom macro targets, and uses a verified database that reduces duplicate or wrong entries. That data quality matters if you track for health reasons beyond weight.

The trade-off is speed. Cronometer favors accurate manual entry over quick photo guesses, so logging a complex meal takes longer. Beginners may find the detail daunting at first. If you want to learn what your food actually contains, Cronometer is the most informative free app here.

Lose It is the easiest weight loss app for beginners. It sets a calorie budget from your goal, shows remaining calories as you log, and tracks weight over time in a clean view. That simplicity helps people who quit other apps because logging felt like work.

The free plan is more limited than FatSecret, especially for barcode scanning, which is now a Premium feature for many users. Premium is comparatively affordable on an annual basis, but free users should expect more manual entry. If you want a simple plan and a calm interface, Lose It is a strong pick.

MyFitnessPal remains useful because its database covers restaurant items, brands, and homemade foods that smaller apps may miss. Basic logging, goals, and device syncing are still free, and long-time users may already have years of history in the app.

The free tier shrank in 2026. Barcode scanning, custom macro goals, meal scan, and ad-free use are now Premium features, which changes the value for new users. Premium costs more per month than many rivals. If you already have history here and you mainly log by search, it still works, but new users should compare FatSecret and Cronometer first.

MyNetDiary is a calm alternative for users who want a verified database without ads. Its free plan includes barcode scanning, nutrient tracking, and a food diary, which covers the core needs for weight loss without constant upgrade prompts. That quiet experience suits users who find other apps noisy.

The community and social features are smaller than MyFitnessPal or FatSecret, and some coaching tools require Premium. If you value accuracy, a clean interface, and free barcode scanning, MyNetDiary is an underrated pick that deserves a trial week.

Yazio suits users who combine calorie tracking with intermittent fasting. Its fasting timer, food diary, and weight tracking sit in one app, so you do not need a separate fasting timer. The interface is clean, and the free plan covers the basics for a first month of tracking.

Pro adds more recipes, fasting plans, and advanced analysis, so free users should expect limits. If fasting is central to your plan, Yazio is a convenient all-in-one choice. If you only need calorie tracking, FatSecret or Cronometer give more free depth.

Lifesum appeals to users who want structure, not just a blank diary. Its guided plans, recipes, and meal ideas help people who struggle to plan meals, and its interface is among the most polished here. For users who like a plan to follow, that guidance can make the first weeks easier.

The free tier is the weakest on this list for everyday tracking, since many plans, recipes, and advanced features require Premium. Barcode scanning on free is also limited in recent listings. Lifesum is best for users who already plan to pay, or who want to test the interface before upgrading.

Carb Manager is built for keto and low-carb users, not adapted to them as an afterthought. It calculates net carbs, tracks macros for keto goals, and offers low-carb recipes and meal ideas. That focus saves keto users from manual net carb math in a general tracker.

General diet users may find its keto-first layout less intuitive, and some advanced features require Premium. If you follow keto or low-carb eating, Carb Manager is the most tailored free option here. If you eat a balanced diet, a general tracker will feel simpler.

Eat This Much answers a different question: what should I eat today. You set calories, diet style, and preferences, and it builds a day of meals with a shopping list. That helps users who know their calorie goal but struggle with planning, which is a common reason diets fail.

As a pure diary, it is less flexible than FatSecret or Cronometer, since its strength is planning rather than logging arbitrary meals. Paid plans add more customization and pantry features. If meal planning is your bottleneck, Eat This Much is a unique and useful free start.
