MyFitnessPal vs Cronometer: Which Tracker Is More Accurate?

Cronometer is the more accurate tracker, mainly because its food data comes from curated sources, while MyFitnessPal's much larger database leans on user submissions that vary in quality. MyFitnessPal wins on sheer food coverage, a huge restaurant and packaged-food catalog, and an interface many people already know. Our verdict: choose Cronometer if you care about correct nutrient numbers, including vitamins and minerals, and choose MyFitnessPal if you mostly want fast calorie and macro logging of branded and restaurant foods.

This is a research-based comparison built from the apps' documented databases, a published athlete study as reported by Biolayne, and third-party pricing guides. It is not a controlled test of our own, and we do not publish measured accuracy numbers we did not take. For single-app reads, see our MyFitnessPal review and Cronometer review.

MyFitnessPal Versus Cronometer at a Glance

The prices come from third-party comparison sites, several of which sell competing apps, and none was an official price page, so verify current pricing on each app's own site before you commit. Both apps also have free tiers that change over time.

Why the Database Decides Accuracy

A food tracker is only as accurate as the entry you pick. MyFitnessPal's catalog is enormous, and a significant share of it comes from user submissions, so two entries for the same food can show different calories, and mistyped entries can sit in the database for years. Cronometer draws on the USDA database, the University of Minnesota's NCCDB and other published sources, which gives it fewer entries but more trustworthy ones. That structural difference is the core of the accuracy gap.

It is not a difference you can erase with care alone, but you can reduce it in either app by choosing entries marked as verified, scanning a barcode and comparing the result to the package label, and weighing food instead of estimating servings.

What the Published Evidence Says

The most credible item we found is a study of endurance athletes comparing the two apps, summarized by Biolayne in a February 2026 piece, "Comparing MyFitnessPal to Cronometer for fitness assessment among athletes." As summarized, MyFitnessPal showed low inter-rater reliability and validity for most nutrients, while Cronometer showed good reliability and validity for most nutrients except fiber, vitamin A and vitamin D. We read the summary, not the full paper, and the study covered a narrow group of athletes, so it may not match what an average user would see.

Several blog posts also repeat a claim that Cronometer matched USDA reference values on 30 of 30 tested foods while MyFitnessPal matched 11. We could not find the original test, so we do not rely on those figures. Even the better app has limits: tracking apps estimate intake, they do not measure it, and self-reported food intake is imprecise in general.

Features That Matter in Daily Use

MyFitnessPal is faster for people who eat out or buy many branded products, because someone has usually logged the item already. Reports indicate it has moved some features, such as barcode scanning, behind its paid tier, so check what the free version includes today. Cronometer shows a long list of micronutrients on every entry, supports custom foods and recipes, and flags where a food has incomplete data, which makes its gaps more visible. People tracking for a specific reason, such as monitoring iron or vitamin B12 intake on a plant-based diet, will probably prefer that detail.

Which Habits Make Either App More Accurate

Whichever app you choose, a few habits narrow the gap. Weigh foods on a kitchen scale instead of eyeballing portions, since serving-size errors are often larger than database errors. Log meals as you eat them so you do not rely on memory, save your usual meals as custom entries after checking them against the label, and pick entries that match the exact brand. Treat daily totals as rough estimates, because a tracker shows a trend and not a laboratory result.

Price and Free Tier

Both apps offer free plans, and both sell a subscription for full features. Third-party guides list MyFitnessPal Premium near $79.99 a year and Cronometer Gold around $50 to $60 a year, though monthly options and promotions appear in some sources. Since the sources disagree and the prices change, verify current pricing and cancellation terms in each app's subscription settings. If the free tier covers what you need, you do not have to pay at all.

Who Should Be Careful With Calorie Tracking

Counting calories and macros is not neutral for everyone. People with a history of an eating disorder, or who notice food logging becoming stressful or obsessive, should talk to a doctor or a registered dietitian before tracking, and may be better off not using these apps at all. The National Eating Disorders Association has resources in the US. Pregnancy, diabetes, kidney disease and other conditions that affect diet also call for individualized guidance, and a calorie target from an app is not medical advice.

How We Compared MyFitnessPal and Cronometer

We compared the two apps using their documented data sources, a published athlete study as summarized by Biolayne, and third-party reviews, and we called out where the evidence was secondhand or came from competitors. We did not run our own head-to-head logging test or measure accuracy ourselves, and we do not claim to have. We are reviewers, not dietitians, so treat this as a tool choice and not a nutrition plan.

The bottom line: pick Cronometer for more trustworthy nutrient numbers, pick MyFitnessPal for the biggest branded and restaurant catalog, and check with a doctor or dietitian before tracking if food, weight or a medical condition is a concern.
