Pros and Cons
Pros
- Fully-free core: calorie, macro, barcode, recipes, exercise — all without subscription
- Premium ($2.99/mo) only removes ads and adds export — not a paywall on core features
- Open API has the longest history of any consumer food database
- Wide international localization (UK, Australia, Germany, Spain, Brazil, Japan all supported)
- Strong community recipes feature
Cons
- UI is utilitarian, dated relative to Lifesum / Yazio
- Database is crowdsourced with the same per-entry noise as MyFitnessPal
- Photo-AI logging is basic; not competitive with Cal AI or Foodvisor
- Ads in the free tier are noticeable, especially on Android
What FatSecret Actually Does in 2026
FatSecret is a calorie tracker built on the most-free model in the consumer category: the entire feature surface (calorie logging, macro tracking, barcode scanning, recipe import, exercise log, weight tracking, community) is free with ads. Premium at $2.99/month only removes ads and adds export — it does not gate any of the core tracking functions.
The food database is built primarily from manufacturer-label imports and community submissions. It is broad and internationally localized — FatSecret has the strongest international packaged-goods coverage outside the EU (Yazio still wins for European data specifically). The open Platform API has been around since the late 2000s and powers a number of third-party nutrition apps.
The product is utilitarian rather than design-led. The UI works; it does not feel polished. For users who care about UI quality, Lifesum or Yazio are nicer to look at; for users who care about free, functional tracking, FatSecret is the answer.

Frequently Asked Questions
Is FatSecret really free?
Yes — the core features (calorie logging, macro tracking, barcode scanning, recipes, exercise log, weight tracking) are all free with ads. Premium ($2.99/month) removes ads and adds CSV export but does not unlock additional core features. This is the most honest free tier in the category.
How does FatSecret compare to MyFitnessPal's free tier?
FatSecret's free tier is materially more useful than MyFitnessPal's free tier. MyFitnessPal paywalls the verified-entry filter, recipe URL import, macro target customization, AI photo, and advanced reports. FatSecret paywalls almost nothing — Premium is mostly ad removal.
Is FatSecret accurate?
Architecturally similar to MyFitnessPal — crowdsourced database with manufacturer-label entries for packaged goods. Per-entry noise is real. For accuracy, Cronometer's verified-by-default approach is structurally better; for free calorie tracking, FatSecret is the right choice.
Does FatSecret have an open API?
Yes — the FatSecret Platform API is one of the longest-running consumer food database APIs. It powers a number of third-party apps. Developer access is available via the FatSecret Platform site.
Why does FatSecret rank lower than apps that aren't free?
Our overall ranking weights all seven criteria. FatSecret wins decisively on Value (95/100) but trails on Accuracy & Database (crowdsourced) and Insights & Reports (lighter than paid competitors). For the specific 'best free tracker' ranking, FatSecret is #1; for the overall 'best tracker' ranking, it lands mid-pack.
FatSecret vs MyFitnessPal Free — which is better?
FatSecret. MyFitnessPal's free tier has been progressively paywalled over the past few years; FatSecret has kept its free tier wide. For a user who refuses to pay a subscription, FatSecret is materially more useful.
