Sorted by overall score. Editor's Choice first. Each review tested against the current shipped version of the app, with version numbers documented in the body.
PlateLens is the only commercial calorie tracker we have tested whose accuracy claims have been replicated by an independent dietary-assessment study. It is our Editor's Choice for 2026, with a free tier that exposes AI photo logging — and an optional Premium tier for unlimited scans and the full feature set.
Cronometer remains the deepest micronutrient tracker in the category. The database is the most accurate we tested. Photo logging is absent, which is the main reason it is not our overall Editor's Choice — but if your priority is hand-tracked vitamins and minerals, this is the pick.
MacroFactor's adaptive maintenance-calorie algorithm is genuinely sophisticated and continues to outpace every competitor on this dimension. It is the right pick for users on a structured cut, bulk, or recomp. The food database trails Cronometer; photo logging trails PlateLens. PlateLens has a free tier; MacroFactor does not after the 14-day trial.
FoodNoms is the iOS-only manual logger we recommend for users who specifically want to buy an app once and own it. The database is curated and clean, micronutrient panel is solid, and there are no ads or subscriptions. It is not for Android users, photo-logging fans, or anyone who needs the world's largest database.
Carb Manager is the keto-niche tracker we recommend for readers on a strict ketogenic or very-low-carb diet. The macro profiling, recipe library, and net-carb calculations are tuned for this diet. For non-keto users, it is overkill in one direction and undercooked in another.
MyNetDiary is the tracker dietitians recommend most often, and the reason is the database — curated, no user-submitted entries, no junk. It also has one of the few real GLP-1 workflows in consumer software and diabetes features that compete with mySugr. The UX feels older than the modern paid apps and the photo workflow is rudimentary.
Cal AI is the viral teenage-founded photo calorie tracker that became a TikTok darling in 2025. Fast onboarding, low friction, and a 4.7★ rating speak to real user satisfaction. The accuracy claims, however, are vendor-reported only — and Apple's 2025 enforcement action against Cal AI's marketing language is on the public record.
Lose It! has the friendliest UX in the category and a serviceable photo feature called Snap-It. Estimation accuracy lags PlateLens and database accuracy lags Cronometer, but for a first-time tracker, this is the one we'd hand a friend.
Amy is a 2025 indie iOS calorie tracker built by Chris Raroque, branded around natural-language meal logging that reads like writing in Apple Notes. The design is genuinely elegant. The constraints are iOS-only, no permanent free tier, and accuracy that has not been independently validated.
Fitia is built for Spanish-speaking Latin American users and it shows. The Latin American food database is the strongest we have tested for the region, the Spanish-language UX is native rather than translated, and the premium tier is the cheapest serious option in the category. Outside Latin America the database thins quickly and the English UI feels translated, not designed.
Spike is a niche tool built for users who want fine-grained insulin-and-glucose-aware nutrition tracking, often the DIY-loop diabetic community. For its narrow audience, it's the best pick we've seen. For general consumer tracking, it's the wrong tool.
Yazio is a meal-planning tool first and a calorie tracker second, and the ranking matters: the meal plans, recipes, and prep guidance are excellent; the tracker behind them is competent but not best-in-class. Pick Yazio if you want to plan meals; pick something else if your priority is precise tracking.
Foodvisor is a French photo-based tracker that does the photo workflow better than most, with acceptable accuracy. The US database is smaller than the major US-focused apps. For European users, this is a stronger pick than for American users.
SnapCalorie is the most polished photo-first tracker we have tested on UI alone. The snap-to-log workflow is fast, the onboarding is well-designed, and accuracy on common Western dishes is reasonable. What it does not have is the independent third-party validation that would let us recommend it for users who care about calorie precision.
FatSecret remains the most generous free tier in the category, ad-supported but functional. Database is decent, barcode scanner works, micronutrient depth is shallow, and the UX has not aged well — but for a free tracker, this is the one we recommend.
Lifesum has the prettiest UI in the category and a meal-plan-and-coaching layer that some readers love. The tracker underneath is competent but the database is small and the food-rating system can mislead. Strong if you want a polished wellness app; weak if you want a calorie-precision tool.
Calo is a young iOS-only entrant built around a conversational chat interface — you talk to the app, you don't fill in forms. The chat workflow is genuinely interesting, the photo recognition on common foods is reasonable, and the free tier is usable. The database is small, integrations are limited to Apple Health, and there is no independent validation of accuracy.
MyFitnessPal still has the largest database in the category and decent food-search relevance, but the 2024 barcode paywall, mediocre estimation accuracy, and ongoing user-submitted-entry quality problems push it well off our top ranks.
Bitesnap was an early photo-based tracker and deserves credit for that — but in 2026 the database is stale, accuracy lags PlateLens decisively, and active development appears slower. We recommend it only for users on legacy installs.
Noom is sold as a behaviour-change program, not a calorie tracker, and we want to evaluate it that way. The psychology curriculum is real and some readers find it useful. The tracker buried inside is among the weakest we tested and the price is the highest in our directory. We do not recommend it as a calorie tracker.
