Genuinely free nutrition tracking

FatSecret is unique in offering a complete nutrition tracking experience at no cost. Its 7M+ food database, barcode scanner, macro tracking, weight log, and food diary are all available without a subscription. The web interface is fully functional for desktop users. This positions FatSecret as the best option for users who need basic nutrition awareness and cannot or will not pay for an app subscription.

Professional dietitian portal

FatSecret Professional is a genuine clinical tool — a web platform where registered dietitians can monitor patient food diaries in real time, generate nutrition intake reports, and track progress across sessions. Over 10,000 healthcare practitioners use this system. For dietitian practices looking for a free patient monitoring solution, FatSecret offers capabilities that other apps charge for through premium tiers.

Developer API

FatSecret maintains a public Food Diary API that has been used by hundreds of health applications, research tools, and clinical software platforms. This developer accessibility has contributed to its longevity and integration breadth despite limited feature investment in recent years.

Verdict

FatSecret is the best option for users who want functional nutrition tracking without any cost. Its professional portal and API also make it valuable in healthcare and developer contexts. For users who want AI features, deep micronutrient tracking, or modern UX, it cannot compete with premium options.

FatSecret 6.7/10

Best free nutrition tracker — no paywall on core features

Frequently asked questions

Yes. FatSecret offers full food logging, barcode scanning, macro tracking, weight logging, and access to its 7M+ food database at no cost with no meaningful premium features locked behind a paywall. The app generates revenue through advertising. There is a premium tier that removes ads, but core functionality is not gated.
FatSecret Professional is a separate web-based platform that allows registered dietitians and healthcare providers to monitor patient food diaries remotely. Patients use the standard FatSecret app, and practitioners access aggregated nutritional data through the professional dashboard. Over 10,000 healthcare practitioners use this system. It's a compelling free option for patient monitoring workflows.
FatSecret's free tier is more comprehensive than most paid app free tiers. Cronometer's free tier is the main competition — it offers better data quality (USDA-only sources) and more nutrients (84 vs 20). For users who prioritize data accuracy and don't mind the database constraints, Cronometer's free tier is superior. For users who want the widest possible food coverage for free, FatSecret has more foods.
