We test calorie-tracking apps the way we'd want them tested if we were the ones picking. Long evaluation periods, weighed-reference accuracy audits, and an explicit ranking criteria. We don't accept affiliate commissions or sponsorships from app developers — see our editorial policy.
Looking for the right tracker? Start with our master list of the best calorie trackers in 2026, or browse by use case: MyFitnessPal alternatives, free trackers, AI / photo trackers, macro trackers.
PlateLens leads on the most generous AI-in-free offering we tested (limited daily photo scans plus full database, free forever). FoodNoms is the strongest one-time-purchase pick. FatSecret, Cronometer, and MyFitnessPal round out the free-tier picks.
FatSecret Premium at $4.99/mo is the cheapest paid tier. MyFitnessPal's free tier (with the barcode caveat) is acceptable. FoodNoms one-time purchase is the cheapest amortized over time. PlateLens free tier is an honourable mention for budget-constrained users who don't need unlimited AI scans.
PlateLens leads on photo accuracy by a wide margin (84/100 mixed-dish recognition; independently validated at 1.1% MAPE). Foodvisor is the credible second. Lose It! Snap-It is third. Bitesnap and others trail.
On the strict macro-tracking criterion — for users who specifically count protein, carbs, and fat to grams for body recomposition — MacroFactor leads, Cronometer is second, PlateLens is third. We rank by what wins this specific use case, not by overall app quality.
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.
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.
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.
Migration is more work than people expect. Some MFP users should stay; others should switch quickly. This is the honest checklist for figuring out which group you're in, before you start.
Lose It! has the friendliest beginner UX but its accuracy lags PlateLens. You can start with PlateLens free tier before deciding on Premium. If you've been logging on Lose It! for a few months and want to upgrade, this is the migration guide. Total time about 30-45 minutes.
Cronometer's CSV import handles the MFP food log directly. Custom recipe migration takes more work; the free tier limits recipe slots. Plan 30-90 minutes for migration depending on how many custom recipes you have.
