Short answer
Pick Cronometer if you want scientifically verified database entries and track micronutrients (84 of them) in addition to calories and macros. Pick MyFitnessPal if you want the largest food database (20 million items, many user-submitted) and primarily track calories and macros for weight management.
Cronometer at a glance
Launched in 2011 with a focus on micronutrient depth. Database pulls from USDA FoodData Central, NCCDB, and other scientific sources, with full attribution on every entry. Tracks 84 micronutrients by default, not just calories and macros. Users include biohackers, athletes, registered dietitians, and anyone on a restrictive diet (vegan, keto, elimination). Strengths: accuracy, scientific rigor, micronutrient depth, solid free tier. Weaknesses: smaller database than MFP, slightly steeper learning curve, less polished social features. Free tier covers core tracking. Gold at $55/year adds custom biometrics and advanced reporting.
MyFitnessPal at a glance
Launched in 2005, the incumbent calorie tracker. 20-million-item crowdsourced food database. Barcode scanner recognizes nearly every packaged food. Macro tracking, exercise logging, community forums, fitness tracker integrations. Premium at $19.99/month or $79.99/year. Strengths: database breadth, brand recognition, data export, decade-plus of existing user data for long-time users. Weaknesses: database accuracy is user-submitted and noisy, free tier increasingly restricted, innovation velocity slowed after acquisitions. The March 2026 Cal AI acquisition added AI photo recognition to the MFP ecosystem.
Pick Cronometer if
- You track for micronutrient coverage, not just calories
- You are on a restrictive diet (vegan, keto, rotation elimination)
- You value scientific accuracy over database size
- You prefer a clean data-first UI
- The free tier's depth matters for your budget
Pick MyFitnessPal if
- You primarily track calories and macros for weight management
- You eat a lot of packaged foods and rely on barcode scanning
- You want the largest possible food database for obscure items
- You already have MFP data from past use
- You value community features and recipe importing
Where they overlap
Both track calories, macros, and fiber by default. Both support barcode scanning. Both integrate with Apple Health. Both have mobile-first experiences. Both offer annual subscription pricing in the $55-80 range for paid tiers. A user could theoretically use both, with MFP for packaged-food logging and Cronometer for micronutrient analysis, but the double-logging burden makes this impractical.
Where they genuinely differ
The database methodology is the core difference. Cronometer uses verified scientific sources (USDA, NCCDB). MyFitnessPal uses crowdsourced user submissions. For packaged foods with barcodes, this difference is minimal. For generic foods (fruits, vegetables, meats, grains), Cronometer's entries are notably more accurate. For micronutrients specifically, Cronometer tracks 84 by default while MFP tracks roughly 15. If you are trying to verify whether you are hitting daily iron, zinc, B12, or omega-3 targets, Cronometer surfaces the data; MFP often does not.
The second real difference is philosophy. Cronometer is a data tool. MyFitnessPal is a behavior-change tool. Cronometer shows you your nutrient profile and leaves the interpretation to you. MFP pushes toward calorie-deficit weight-management defaults. For people who want to understand their eating rather than follow a weight-loss program, Cronometer is a better fit.

Bottom line
If you already know what you eat and want to see the micronutrient picture, Cronometer. If you are counting calories to lose weight and want the largest database, MyFitnessPal. Most users do not need both. Pick the one that matches the question you are actually trying to answer.
