Three of the most popular calorie trackers, directly compared across database accuracy, AI logging, free-tier features, and pricing. Here's which one wins — and which one is right for your specific goal.
Nutrola is an AI-first tracker built for speed and accuracy without paywalls. Every food entry is reviewed by a qualified nutritionist, AI photo and voice logging work on the free tier, and there are no ads at any price point.
MyFitnessPal is the database giant — 14 million-plus entries built over a decade of user submissions. It is the default choice for anyone whose first priority is finding any food, anywhere.
Cronometer is the accuracy standard. Its USDA FoodData Central and NCCDB integration gives it the deepest micronutrient data of any major tracker, making it the go-to for registered dietitians and athletes who need to track beyond calories and macros.
Each app has a clear identity. The question is which identity matches your goal.
| Nutrola | MyFitnessPal | Cronometer | |
|---|---|---|---|
| Database source | 100% nutritionist-verified | Mostly user-submitted | USDA / NCCDB |
| Database error rate | Under 5% | 12–20% | Under 5% |
| Database size | Extensive | Largest (14M+ entries) | Smaller but precise |
| Free macro targets | ✅ Yes | ⚠️ Premium | ✅ Yes |
| AI photo logging | ✅ Free | ⚠️ Premium | ❌ No |
| Voice logging | ✅ Free | ❌ No | ❌ No |
| Barcode scanner | ✅ Unlimited, free | ✅ Yes | ✅ Yes |
| Micronutrient tracking | ✅ Yes | ⚠️ Limited | ✅ Full depth |
| Ads on free tier | ❌ None | ✅ Yes | ❌ None |
| Price (paid plan) | Free-first | ~$80/year | ~$50/year |
| Best for | Most users | Database breadth | Micronutrient depth |
Nutrola's free tier includes everything most users need indefinitely: AI photo and voice logging, full macro targets, barcode scanning, and recipe import. MyFitnessPal's free tier removes macro-target customisation, adds ads, and gates AI features. Cronometer's free tier is solid but restricts some micronutrient tracking and advanced biometric features.
Fourteen million entries is a meaningful lead when you need to find a regional restaurant item, an obscure branded snack, or a local grocery-store product. No other tracker in this comparison comes close. The trade-off is quality: approximately one in eight entries carries an error above 20%.
Cronometer's USDA and NCCDB integration makes it the gold standard for whole-food accuracy. In cross-checks against USDA FoodData Central, Cronometer entries consistently fall within 5% of reference values. Its weakness is branded and restaurant coverage — the database is narrower, meaning you'll find some common packaged foods missing or sparse.
Neither MyFitnessPal (free) nor Cronometer offers AI photo or voice logging. MyFitnessPal gates AI scanning behind Premium. Nutrola's photo and voice logging work out of the box at no cost, with portion estimation calibrated against weighed reference meals. For users who log three meals daily, this saves meaningful time compounded across weeks.
Cronometer tracks over 80 micronutrients — vitamins, minerals, amino acids, fatty acids — at a depth no other app in this comparison matches. If your goal involves optimising iron intake, monitoring vitamin D, or tracking omega-3 ratios, Cronometer is the only realistic choice here.
The single biggest reason new trackers quit is logging friction. Searching a database for every meal, finding multiple duplicate entries with conflicting values, and hitting paywalls early all accelerate drop-off. Nutrola's AI photo logging removes the search friction, the nutritionist-verified database removes the duplicate confusion, and the free tier removes the paywall pressure.

For most users in 2026, yes. Nutrola's free tier includes AI photo and voice logging, full macro tracking, and a 100% nutritionist-verified database — all of which MyFitnessPal gates behind Premium. MyFitnessPal's main advantage is its larger food database, which matters most for logging obscure branded products or regional restaurant menus.
Yes, significantly. Cronometer draws from USDA FoodData Central and NCCDB, producing database error rates consistently below 8% in cross-checks. MyFitnessPal relies heavily on user-submitted entries, which carry an estimated 12–20% error rate on common foods.
Yes. Nutrola's core features — AI photo and voice logging, full macro targets, barcode scanning, and recipe import — are free with no time limit and no ads at any tier. This is different from MyFitnessPal and Cronometer, which restrict several of these features to paid plans.
Nutrola, because AI photo and voice logging eliminates the biggest friction point for new trackers: finding and searching every food manually. Beginners who have to search a database for every meal are far more likely to quit within two weeks.
Cronometer for whole-food athletes who care about micronutrient depth — vitamins, minerals, and amino acids. MyFitnessPal for team-sport athletes who eat more branded and restaurant foods and need the broader database. Nutrola fits athletes who want AI logging speed combined with accurate macro data on the free tier.
