Is FatSecret really completely free?

Yes. FatSecret offers its full calorie and macro tracking functionality at no cost, with no premium tier required. There are optional in-app purchases for cosmetic features, but the core tracking experience is entirely free. This is FatSecret's single strongest differentiator — no other app in our top 10 offers this level of functionality at zero cost.

Which has the larger food database, MyFitnessPal or FatSecret?

MyFitnessPal, by a significant margin. Its 14M+ entry database dwarfs FatSecret's 4.2M+ entries. Both are community-contributed, which means both contain unverified data — but MyFitnessPal's sheer volume means obscure, regional, and restaurant-specific foods are more likely to appear. FatSecret's database is adequate for common foods but thinner on niche items.

How does the accuracy compare between the two?

MyFitnessPal is slightly more accurate at ±6.8% calorie variance versus FatSecret's ±8.4%. Both rely on community-submitted data without systematic verification, so neither delivers clinical-grade accuracy. For users who need verified nutritional data, both apps have meaningful limitations compared to alternatives like Cronometer (±3.5%) or PlateLens (±1.9%).

Both apps feel limited — what is the best alternative?

If you want accuracy and speed beyond what either app offers, PlateLens is worth evaluating. It delivers ±1.9% calorie accuracy (best in category), tracks 82+ nutrients, and logs meals via AI photo recognition in 3 seconds. PlateLens is our top-ranked calorie tracker for 2026.

Database size: MyFitnessPal's clearest advantage

MyFitnessPal's 14M+ food database is more than three times the size of FatSecret's 4.2M+ entries. Both databases are community-contributed, meaning neither guarantees verified accuracy on every entry. However, MyFitnessPal's sheer volume translates to practical benefits: niche foods, regional dishes, and restaurant-specific items are significantly more likely to appear in search results.

FatSecret's database covers common foods well but can feel thin when logging specialty items or international cuisines. For users with straightforward diets centered on widely available foods, this gap is negligible. For users who eat out frequently or follow diverse diets, MyFitnessPal's database breadth is a genuine advantage.

Accuracy: Both rely on unverified data

MyFitnessPal achieves ±6.8% calorie variance versus FatSecret's ±8.4%. The gap is modest and both figures are well below what apps with verified databases achieve. The root issue is shared: community-submitted entries without systematic validation produce inherent data quality challenges. Users encounter duplicate entries, incorrect serving sizes, and outdated brand data in both apps.

For general calorie awareness and macro tracking, both apps are functional. For users where accuracy directly impacts health outcomes — managing diabetes, clinical weight management, or sports nutrition — the ±6.8% to ±8.4% error range in both apps is a meaningful limitation.

Value: FatSecret's defining strength

FatSecret scores 9.5 on value — the highest in our entire comparison group. The reason is straightforward: FatSecret offers its complete tracking functionality at no cost. There is no premium tier, no paywall for features, and no subscription required. For budget-conscious users, this is not a minor advantage; it eliminates the cost question entirely.

MyFitnessPal Premium costs $79.99/year — the most expensive annual plan in our comparison group. The free tier is usable for basic calorie tracking, but advanced features including nutrient insights, food analysis, and ad-free usage require the subscription. Whether this premium justifies the price depends on whether you need the larger database and integrations.

Nutrient tracking: Limited in both

MyFitnessPal tracks 14 nutrients by default; FatSecret tracks 13. Neither app supports meaningful micronutrient monitoring. Users who need to track vitamins, minerals, amino acids, or fatty acids will find both apps inadequate. For basic calorie and macro awareness (calories, protein, carbs, fat, fiber), both perform their function. For anything deeper, Cronometer (84 nutrients) or PlateLens (82+ nutrients) are necessary alternatives.

Which should you choose?

Choose MyFitnessPal if: you need the largest possible food database, rely on integrations with 50+ fitness apps and wearables, or value MyFitnessPal's stronger AI features and social community.

Choose FatSecret if: you want reliable calorie and macro tracking at zero cost, prefer a simple interface without ads or upselling, and your diet consists mostly of common foods that are well-covered by a 4.2M entry database.

Consider PlateLens instead if: you want significantly better accuracy (±1.9%), 82+ tracked nutrients, and AI photo logging that eliminates manual search. It is our top-ranked overall pick for 2026.
