MyFitnessPal, Yazio, FatSecret, Lifesum and Cronometer compared: food databases, barcode scanning, diet plans and micronutrient tracking for losing weight.
Losing weight mostly means sustaining a calorie deficit, and a phone makes the logging quick enough to keep doing: scan a barcode, pick the dish, done. The five leading counters differ less in the basic arithmetic than in philosophy. MyFitnessPal owns the giant database, FatSecret gives the most away free, Yazio wraps weight loss and fasting in the cleanest visuals, Lifesum judges diet quality and supplies plans, and Cronometer is built around verified micronutrient data. The 5 apps in this guide cover that spread, selected for the different ways people actually stick with tracking — serious record-keeping, zero cost, visual motivation, structured eating plans or scientific precision. Pick the one whose daily friction you can tolerate; consistency beats any feature list.
MyFitnessPal is the category benchmark: the world's largest food database and a fast barcode scanner for serious calorie and macro logging.
MyFitnessPal is the reference most other counters are compared against, and the reason is its database — the largest collection of foods in the world, from supermarket barcodes to restaurant dishes, which makes logging a meal a matter of seconds with its fast scanner. It tracks calories and macronutrients, connects to wearables and exercise apps and carries years of community entries. The product has moved steadily behind a paywall: many functions now require Premium, user-submitted data can show varying or wrong calorie figures, and free logging is deliberately slower for some workflows. If you want the deepest catalogue and accept upsells, nothing else matches it; if you refuse to pay, FatSecret is the honest alternative.
Yazio is the clean, visual weight-loss counter: a clear daily calorie budget, fasting tracking and a 4-million-food database with recipes.
Yazio is designed to be kept. The home screen presents the day's remaining calorie budget in plain visual terms, which removes the arithmetic that makes people quit, and the app wraps weight-loss tracking and intermittent fasting timers around a database of more than 4 million foods plus a library of healthy recipes. For someone starting their first serious cut, the learning curve is the gentlest of the five. Its free version is deliberately limited — full meal plans and recipes are PRO-only, advertising appears outside the paid tier — so it functions as a long sales pitch that many users happily convert on. If motivation through design is what you need, it earns its place; strict free users should look at FatSecret.
FatSecret is the most complete counter that stays free: logging, barcode scanning, an exercise diary and a community with no paywall.
FatSecret is the answer for anyone refusing a subscription. Without paying, it offers meal logging, a barcode scanner, an exercise diary, a broad food database and an active community, plus a clear if unflashy interface — essentially the serious-logging toolkit MyFitnessPal charges for. The compromises are aesthetic and depth rather than function: the design looks more dated than Yazio's polished screens, the recipe and meal-plan libraries are thinner than the paid apps', and discreet advertising appears in the free app. For a user motivated by price, none of those is decisive. Combined with a little patience for its looks, it is the best zero-cost route to consistent counting in this guide.
Lifesum pairs calorie counting with eating plans — keto, Mediterranean, fasting — and scores diet quality, in the most attractive design of the five.
Lifesum's pitch is that quantity alone is a dull metric. Alongside the food log it offers structured plans (keto, Mediterranean, intermittent fasting and others), rates the nutritional quality of your day rather than just its calories, and serves personalised advice aimed at eating better rather than merely eating less. The interface is genuinely the most polished and motivating in the category, which matters in an app you open before every meal. The trade-off is the paywall: the best features and full plans live in Premium, and the food database, while adequate, is smaller than MyFitnessPal's, so niche branded products can be missing. Choose it when habit-building and diet direction matter more than exhaustive logging.
Cronometer is the precision instrument: verified data and 80-plus micronutrients for users who treat nutrition scientifically.
Cronometer is built for the advanced user. Beyond calories and macros it tracks more than 80 micronutrients — vitamins, minerals, amino acids — and its database is verified rather than open to user edits, which removes the inconsistent figures common in community catalogues. Athletes, people managing specific diets and anyone who genuinely wants to know their magnesium or omega-3 intake get a tool nobody else in the guide rivals at that depth. It is correspondingly less approachable: casual users find the density intimidating, the overall database is smaller than MyFitnessPal's for branded and restaurant foods, and the Gold features that complete the analysis are paid. Start elsewhere to build the habit; move here when data quality becomes the priority.

Questions & answers
What is the best free calorie counter?
FatSecret is the most complete free option: meal logging, barcode scanner, exercise diary and community, all without a paywall. MyFitnessPal still offers a free tier with the category's biggest database, even after moving features to Premium. For micronutrient accuracy at no cost, Cronometer's free version tracks far more detail than most people use; paying only becomes necessary when you want its Gold analysis.
Do calorie apps really help you lose weight?
Yes, because weight loss comes down to a sustained deficit — burning more than you eat — and logging reveals how much you actually consume, which is almost always more than the estimate in your head. The deciding factor is not which app you pick but daily use, so choose the quickest, least annoying logger for your taste; Yazio and MyFitnessPal are both built around that speed. A counter cannot create the deficit, but it makes denial honest.
Is counting calories risky or potentially obsessive?
It is a useful tool for most people when treated as a short, honest guide to habits, not a permanent scoreboard. Anyone with a current or past eating disorder should speak to a professional before starting. Several apps deliberately support a healthier relationship with the numbers — Lifesum can emphasise diet quality over totals, and most let you hide calorie displays — which is worth setting up if strict counting starts generating anxiety rather than insight.
