Calorie Tracker Database Size Comparison 2026: How Many Foods Does Each App Actually Have?

Every calorie tracking app advertises its database size as a selling point. "14 million foods." "Largest food database in the world." These numbers sound impressive until you realize that a database with 14 million entries and 70% duplicates or unverified data may be less useful than a database with 1 million carefully curated entries. When you search for "grilled chicken breast," would you rather see 200 entries with wildly different calorie values, or 5 verified entries that are actually correct?

Database size is one of the most important features of any calorie tracker, but raw numbers tell only part of the story. What matters is whether the app has the specific foods you eat, whether those entries are accurate, and whether the database is maintained over time.

We dug into the databases of 10 calorie tracking apps to compare not just how many foods they have, but how useful those foods actually are.

Why Database Composition Matters More Than Size

A 2022 analysis published in Public Health Nutrition examined the databases of four major calorie tracking apps and found that larger databases correlated with higher duplicate rates and more user-submitted entries containing errors. The study concluded that "database quality, not quantity, was the primary predictor of user logging accuracy."

Here is why each dimension matters:

• Total size determines whether you can find niche or regional foods.
• Verified entries determine whether the data you find is correct.
• Regional coverage determines whether the app works well outside the United States.
• Brand coverage determines whether your specific packaged foods are available.
• Restaurant coverage matters if you eat out frequently.
• Update frequency determines whether reformulated products have current nutrition data.
• User-submitted percentage indicates the reliability risk — higher percentages mean more potential for errors.

Methodology

We assessed each app's database between January and March 2026 through:

• Official disclosures from app websites, press releases, and developer documentation.
• Search testing using 200 standardized queries: 50 whole foods, 50 US branded products, 50 EU branded products, 25 restaurant meals (US chains), and 25 regional specialty foods from 5 countries.
• Duplicate analysis by searching 20 common foods and counting distinct entries returned.
• Freshness testing by searching for 20 products known to have been reformulated in 2024-2025.
• Where official numbers were not publicly available, we used our best estimates based on search behavior, user reports, and available documentation.

App-by-App Analysis

MyFitnessPal

MyFitnessPal claims the largest database at 14 million+ foods, and in terms of raw search results, nothing comes close. Search for almost any food and you will get results. The problem is choosing the right one. Our duplicate analysis found an average of 47 distinct entries for common foods like "banana" or "chicken breast," with calorie values varying by 30-50% between entries.

Approximately 86% of the database is user-submitted, meaning the majority of entries have never been professionally verified. MyFitnessPal has added verified badges and prioritized verified results in search, which helps, but the sheer volume of unreliable entries creates noise. Brand coverage in the US market is outstanding — virtually every packaged product sold in the US is in the database. International coverage is significantly weaker, with many EU products missing or containing US nutritional data for similarly named products.

Restaurant coverage is the best we tested, with over 1,000 chain restaurants represented.

FatSecret

FatSecret's 12 million+ foods is the second-largest claimed database, but with an estimated 92% user-submitted content, it has the highest unverified percentage in our comparison. Duplicate rates were the highest we tested, with some common foods returning 60+ entries. The free tier and open API have made it popular as an embedded database for other apps, but the data quality challenges are significant.

Lose It!

Lose It! claims 7 million+ foods with a mix of crowdsourced and licensed data. About 21% of entries are verified, which is better than FatSecret but still means roughly 4 out of 5 entries are user-submitted. US brand coverage is strong, but regional food coverage outside North America is limited.

Yazio

Yazio claims 4 million+ foods and benefits from strong European food data, particularly German and Central European products, thanks to integration with the German BLS (Bundeslebensmittelschluessel) food composition database. About 38% of entries are verified. For users in Europe, Yazio often surfaces regional products that US-centric apps miss entirely.

Samsung Food

Samsung Food has built a 2 million+ entry database that covers 20+ countries, leveraging Samsung's global presence. Approximately 40% is verified, sourced from various government food composition databases. The database is well-suited for users in Samsung's key markets (South Korea, US, EU) but has gaps for smaller markets.

Nutrola

Nutrola's 1.8 million+ foods may look modest next to MyFitnessPal's 14 million, but approximately 85% are verified entries from USDA, European food composition databases, and manufacturer-verified data. This means Nutrola has roughly 1.5 million verified entries — comparable to the number of verified entries in databases three to seven times its size.

Regional coverage spans 30+ countries, with particularly strong US and EU product coverage. The database includes both USDA-sourced nutrition data and European food composition data, so a "Müsli" search returns accurate German products, not just American granola. Restaurant coverage includes 500+ chains across multiple countries.

The user-submitted portion (approximately 15%) goes through a verification queue rather than being immediately published, which prevents the duplicate and error accumulation that plagues larger crowdsourced databases. Update frequency is monthly for manufacturer data and product reformulations.

MacroFactor

MacroFactor's 1.2 million+ foods are predominantly verified (~80%), sourced primarily from USDA and NCCDB databases. The search algorithm is well-designed, surfacing verified entries first and clearly labeling data sources. Restaurant coverage is more limited than larger apps at 250+ chains. Regional coverage is US-heavy, which can be a drawback for international users.

Cronometer

Cronometer has the highest verified percentage at approximately 95% of its 1 million+ entries. Data comes from USDA, NCCDB, and direct manufacturer submissions. For micronutrient data specifically, Cronometer is unmatched — entries include data on 80+ nutrients that most other apps do not track. The trade-off is the smallest total database in our comparison and limited restaurant coverage at 200+ chains.

Lifesum

Lifesum's 800K+ foods come from a mix of licensed databases and user submissions, with about 63% verified. Brand coverage is moderate, with reasonable EU and US representation. The relatively smaller database means you are more likely to need manual entry for specialty or regional items.

Noom

Noom's approximately 1 million foods are primarily from licensed databases, with about 45% verified. The database is US-focused, and restaurant coverage is the most limited in our comparison at around 100 chains. Noom's strength is its behavioral coaching, not its food database depth.

The Duplicate Problem: Bigger Is Not Always Better

To illustrate the duplicate issue in crowdsourced databases, we searched for "banana, medium" across all 10 apps and counted distinct entries with different calorie values:

App	Entries Returned	Calorie Range	Verified Entries
MyFitnessPal	54	72-135 kcal	3
FatSecret	61	68-140 kcal	2
Lose It!	38	75-130 kcal	4
Yazio	22	80-120 kcal	8
Nutrola	8	89-110 kcal	7
Cronometer	5	93-110 kcal	5
MacroFactor	6	90-112 kcal	5
Samsung Food	15	82-125 kcal	6
Lifesum	12	85-118 kcal	7
Noom	14	80-122 kcal	5

The USDA reference value for a medium banana (118g) is 105 kcal. In MyFitnessPal, the range of returned values spans from 72 to 135 — a 63-calorie spread for one of the simplest possible foods to log. In Cronometer, the range is 93 to 110 — a 17-calorie spread. The smaller, curated databases are not just more accurate on average; they are more consistent, which means users are less likely to accidentally select a wildly incorrect entry.

Regional Coverage: The Hidden Gap

Most database size comparisons focus on US foods, but for the estimated 60% of calorie tracker users outside the United States, regional food coverage is critical. We searched for 25 regional specialty foods from Germany, Japan, Brazil, India, and France:

App	Foods Found (of 25)	With Accurate Data
Nutrola	21	19
Yazio	20	17
Samsung Food	18	14
MyFitnessPal	17	11
Cronometer	14	13
Lose It!	12	8
FatSecret	15	7
Lifesum	13	10
MacroFactor	11	10
Noom	8	6

Nutrola and Yazio led in regional food availability, reflecting their investment in European and international food composition databases. Cronometer found fewer items but those it found were highly accurate. MyFitnessPal found many items thanks to its crowdsourced breadth, but only 11 of 17 had accurate nutritional data.

Key Takeaways

Headline database numbers are misleading. A database with 14 million foods and 14% verification is not inherently more useful than a database with 1.8 million foods and 85% verification. What matters is whether your specific foods are there and whether the data is correct.

Duplicates actively harm accuracy. When a user sees 54 entries for "banana" with a 63-calorie spread, the chance of selecting the wrong one is high. Smaller, curated databases eliminate this problem by design.

Regional coverage is a real differentiator. If you live outside the US and eat local foods, your app options narrow significantly. Yazio, Nutrola, and Samsung Food offer the strongest international food data.

Restaurant data is US-centric across the board. Even the apps with the most restaurant entries focus overwhelmingly on US chains. International restaurant coverage remains a gap industry-wide.

Update frequency prevents data decay. Food products change constantly. Apps that update monthly or more frequently serve more accurate current data than those updating quarterly or less.

Our Pick

For users who prioritize finding any food quickly and live in the US, MyFitnessPal has the broadest database — but you must be careful to select verified entries.

For users who want the highest data quality per entry, Cronometer leads with 95% verified data and unmatched micronutrient depth, though its total coverage is the smallest.

For users who want the best balance of verified accuracy, database breadth, regional coverage, and modern features, Nutrola offers 1.8 million+ foods with 85% verification across 30+ countries at €2.50 per month. The combination of a large verified database with AI-powered search means you find accurate entries fast — without wading through dozens of duplicates.

For European users specifically, Yazio deserves consideration for its strong European food composition data.

FAQ

Which calorie tracker has the biggest food database?

MyFitnessPal claims the largest database at 14 million+ foods, followed by FatSecret at 12 million+. However, the majority of entries in both databases are user-submitted and unverified. In terms of verified entries, Nutrola (1.5M), MyFitnessPal (2M), Yazio (1.5M), and Lose It! (1.5M) lead.

Does a bigger food database mean more accurate tracking?

Not necessarily. Our testing found that the apps with the smallest databases (Cronometer, MacroFactor) had the lowest error rates, because a higher proportion of their entries were professionally verified. Larger crowdsourced databases introduce duplicates and unverified entries that can reduce accuracy if users select incorrect entries.

Which calorie tracker is best for European foods?

Yazio and Nutrola offer the strongest European food coverage. Yazio benefits from German BLS database integration, while Nutrola covers 30+ countries with multiple European food composition databases. Cronometer is also strong for whole foods but weaker on European branded products.

How often do calorie tracker databases get updated?

Update frequency varies significantly. Nutrola and Yazio update monthly. Cronometer and MacroFactor update quarterly. Apps with crowdsourced databases (MyFitnessPal, FatSecret, Lose It!) receive continuous user submissions, but these are not the same as verified updates.

Why do I see different calorie counts for the same food in my app?

This is the duplicate problem common in crowdsourced databases. Multiple users may have submitted entries for the same food with different portion sizes, preparation methods, or simply incorrect data. Choose entries with a verified badge or check values against the USDA FoodData Central website for reference.

Can I add my own foods to calorie tracking apps?

Yes, all 10 apps in our comparison allow custom food entry. The key difference is what happens after you add it — in some apps, your entry becomes publicly available to all users without verification, contributing to the crowdsourced quality challenge. Other apps keep custom entries private or route them through a verification process.
