Cronometer vs MyFitnessPal: Which Calorie Tracker Should You Use?

Quick answer

Pick MyFitnessPal if you want the fastest logging and the biggest food database, and you mostly care about calories and the three main macros. Pick Cronometer if you care about micronutrient accuracy, want vitamins and minerals tracked properly, and you eat a lot of whole foods. If you also want a training plan and an optional coach in the same place, Trainera does calorie and macro logging alongside workouts on a free plan.

MyFitnessPal: strengths and weaknesses

MyFitnessPal is the app most people try first, and there is a good reason. The food database is enormous. If you eat packaged foods, restaurant meals, or regional brands, chances are someone has already logged it. Logging is fast, the interface is familiar, and recipe import and meal copying save real time once your routine settles in.

The catch is accuracy. Because most entries are crowd-sourced, you often find five versions of the same yogurt with different numbers. You have to develop an eye for which entry looks right, or verify against the label. For calorie counting this is usually close enough. For anything precise it means extra effort.

The bigger change in recent years is the paywall. Features that used to be free now sit behind MyFitnessPal Premium. The barcode scanner, custom macro splits by gram or percentage, more detailed nutrient breakdowns, and the food-photo logging tool are Premium in 2026. The free version still lets you log meals and see calories, but the daily experience is heavier on ads and nudges to upgrade. If you only want to count calories with a barcode, that scanner paywall stings.

Who MyFitnessPal suits

People who want speed and coverage over precision. If your goal is a rough calorie deficit or surplus and you eat a wide mix of branded foods, it does the job well, especially if you accept Premium for the scanner.

Cronometer: strengths and weaknesses

Cronometer took the opposite path. Instead of the biggest database, it built a curated one sourced from references like the USDA and NCCDB, plus verified brand entries. When you log a whole food such as spinach, salmon, or oats, you get a reliable micronutrient profile: vitamins, minerals, amino acids, omega ratios. It tracks 80+ nutrients, which is far beyond what most apps show.

This makes Cronometer the better tool for anyone who cares about more than calories. If you follow a specific diet, manage a deficiency, watch sodium or potassium, or just want to see whether you actually hit your fiber and iron, the depth is genuinely useful. The free tier is also generous. Core tracking, custom macro targets, and a limited barcode scanner are available without paying. Gold removes limits, adds features like nutrient timing charts and more custom foods, and clears the light ads.

The trade-offs are real too. The database is smaller, so obscure regional or restaurant items may be missing and you enter them by hand. Logging can feel slower and more clinical than MyFitnessPal. Some people love that precision, others find it more app than they wanted for a simple cut.

Who Cronometer suits

Whole-food eaters, people tracking micronutrients for health reasons, and anyone who wants trustworthy data over sheer database size.

Where Trainera fits

Both apps above do one job: nutrition logging. Trainera treats nutrition as one half of the picture. It does calorie and macro logging with a barcode scanner and AI food-photo logging, so you can snap a plate and get an estimate instead of searching manually. On top of that it builds training plans, and you can add a real coach if you want structure and accountability. The free plan covers calorie and macro tracking, so you can start without paying.

The point is not that Trainera has more nutrients than Cronometer or a bigger database than MyFitnessPal. It does not claim that. The point is that most people logging food are also training, and switching between a workout app and a nutrition app gets old. Having your calories, macros, plan, and coach in one place removes that friction. If micronutrient depth is your main need, Cronometer still wins on that specific axis. If you only ever want to count calories, MyFitnessPal is fine. If you want food and training connected, that is Trainera's lane.

How to choose

Start with what you actually need. If you want the least friction and the widest food coverage, and you do not mind Premium for the scanner, go MyFitnessPal. If you want accurate micronutrients and eat mostly whole foods, go Cronometer, and its free tier may be all you need. If you are training toward a goal and want nutrition and workouts in one app with a free starting plan, try Trainera.

A practical tip: pick one and log for two weeks before judging. Any of these three works if you use it consistently. The best calorie tracker app is the one you actually open every day, and that usually comes down to how the logging flow feels to you and whether the free tier covers what you need.
