A nutrition tracking app has one job: turn what you ate into numbers you can trust, with little enough effort that you still do it in month three. Most people who quit do so because logging a home-cooked dinner takes ten taps, or because the one feature they relied on moved behind a paywall after an update. This ranking is written for individuals, coaches who ask clients to keep a food log, and employers who subsidize an app for staff. We read each vendor's own legal pages, privacy notice and pricing page, and judged twelve products on five tests: how fast logging becomes routine, what the paid tier really costs, whether your diary can leave with you, who holds the data and under which law, and which kind of eater each app suits. The order is the verdict, and the largest incumbent is placed below smaller products that earned a higher slot.
Visibility in this ranking can be paid for. Payment moves a vendor's position within the
shortlist; it never adds a vendor, and it never changes a word of the review. The largest vendors in nutrition tracking apps

How we ranked these
Setup: the target, the database and the first week of logging
The first evening matters less than the fifth day. Any app can ask for your height, weight and goal and hand back a calorie number; what separates them is how quickly the second, third and tenth meal get logged. We looked at how entries are made (barcode, photo, voice, typed search, copying yesterday), how the vendor describes its food database, and whether you can import a recipe from a web address instead of typing ingredients. Databases split into curated ones, where staff or labs check entries, and crowd-fed ones, where duplicates and wrong values are common. Apps that let you set your own calorie and macro targets for free sit higher than those that lock the target to a subscription, because a wrong default in week one ends the habit.
The real price: what the free tier withholds and how renewal is billed
Nine of the twelve products here have a free plan, and the free plan is where the differences hide. The usual paywall items are barcode scanning, ad removal, custom macro targets, photo logging and long-range statistics. Billing shape matters as much as price: some vendors sell a monthly plan, some only a prepaid term of several months, and one sells no free version at all. We priced the realistic case, one person logging daily for a year, and noted when a vendor publishes no figure on the pages we read. A published annual price that works out near five dollars a month and a monthly price near twelve describe the same product; the gap is the penalty for not committing.
Getting your data out: the diary, the weight trend and the deletion clock
A food diary is a few years of a person's weight, eating habits and sometimes health conditions, so what happens to it on exit is a fair test. We searched each vendor's privacy notice for an export route, a statement of the right to data portability, and a retention rule. MacroFactor states that you can export or delete your data from within the app. YAZIO, Lifesum and Fitatu cite the portability right under European data protection law. Nutracheck deletes accounts after three years without use, and Cronometer says it may delete accounts idle for 36 months. Where a notice named no export file format, we say so in the entry rather than assume one exists.
Independence from the vendor: ownership, hosting and where the AI runs
Nutrition data counts as health data in most privacy regimes, so the controlling company and the servers matter. Cronometer says it stores information on HIPAA-compliant servers in the United States, and MacroFactor's notice names Google's Firestore in the USA. YAZIO runs its website on a German host and names OpenAI Ireland as the processor behind its AI functions, with a data processing agreement and a statement that inputs are not used for training. Lifesum relies on the EU-U.S. Data Privacy Framework and standard clauses for transfers outside the European Economic Area. Snapkin states that its server is in Amsterdam while its photo analyser runs in the United States. MyFitnessPal is a Texas controller with an appointed EU representative. Photo logging adds a second processor to every meal, so we weighed who it is and what the notice promises.
Who it's for: lifters, dieters, families, patients and professionals
The categories of user are further apart than the marketing admits. Someone cutting body fat for a competition wants a trend algorithm that adjusts targets weekly. Someone managing a diet prescribed for a medical reason wants micronutrients and a database where a missing entry is rare. A casual dieter wants a free app with a barcode scanner and nothing else. A household that plans dinners wants a planner more than a logger. A dietitian running clients wants shared access, which is only offered by some vendors. We ranked on how well each product serves its core user, and each entry names who it fails.
The 12 tools, reviewed
#1 Cronometer
Nutrient-level food tracker with a verified database · Canada · cronometer.com
Verified database Micronutrients Free barcode scanner
Cronometer is the entry that gives a new user the most before asking for money. The free version includes the barcode scanner and the same food database that paying members see, and Gold at $59.99 a year adds the things a heavy user eventually wants: no ads, custom charts, nutrition scores, a recipe importer that builds a custom recipe from a web address, and a search that suggests foods rich in a nutrient you are missing. The company is Canadian and describes cases where a school or other organization engages it and it acts as processor. That mix of a usable free plan and attention to vitamins and minerals is why it leads.
Where it falls short
The privacy notice says information is stored on HIPAA-compliant servers in the United States, which is a consideration for a Canadian or European user. The company's address on that notice is a post office box in Revelstoke, British Columbia. We found no statement about an export file on the pages we read. The free version shows ads, and several features that serious users like sit in Gold.
Wrong for
Someone who wants every vitamin and mineral tracked but also wants the diary stored in Europe, or a user who dislikes ads and does not want to pay. YAZIO or MacroFactor fit those cases better.
Pricing: Free with ads; Gold is listed at $10.99 per month or $59.99 per year, which the page shows as $4.99 per month billed annually. (free plan)

#2 MacroFactor
Adaptive macro tracker with weekly target adjustments · United States · macrofactor.com
Adaptive targets No ads Weight trend
MacroFactor treats the calorie target as something to be measured on you instead of calculated once. You log food and weight, and its coaching mode revises the target each week from your trend, with goal settings for bulk, cut and maintenance. The vendor says the app carries no ads, uses no ad networks, and lets you export your data at any time. Logging has several routes: AI photos, barcode, label scanner, a recipe importer and speech. The company publishes three billing terms and states plainly that no free version exists, which makes the cost easy to compare and keeps it out of the top slot for casual users.
Where it falls short
There is no free version and, per its own FAQ, there never will be, only a 7-day trial. The notice names Google's Firestore in the USA as the storage processor. The FAQ says branded product and barcode coverage in Europe is still being expanded, so a European shopper should test local groceries first. The design is built around a weight goal, not around a medical diet.
Wrong for
A casual user who wants a free calorie counter, or a European who needs full local barcode coverage today. Cronometer's free plan or YAZIO suits those buyers better.
Pricing: No free version; $11.99 per month, $47.99 per six months or $71.99 per year, after a 7-day free trial. (free trial)

#3 YAZIO
German calorie counter with optional AI photo logging · Germany · yazio.com
German company AI photo tracking Fasting timers
YAZIO's privacy notice is unusually specific for a consumer app. It names YAZIO GmbH in Erfurt as controller, gives a data protection officer, names dogado GmbH in Dortmund as the web host, and says OpenAI Ireland runs its AI functions under a data processing agreement with a promise that inputs are not used to train models. Its help center states that all calorie-counting functions are free, with the recipe library of over 3,000 and longer statistics reserved for PRO. For a European user who wants a free tracker with a clear legal footing, it is the safest of the free options.
Where it falls short
PRO is sold only as a prepaid 3- or 12-month term, charged in full at the start, so there is no cheap month to test it. The notice says some AI data may reach OpenAI Inc. servers in the USA under the EU-U.S. Data Privacy Framework or standard clauses. Recipes and extended statistics are paywalled, and we did not find a list price on its pages.
Wrong for
A user who wants a monthly subscription they can drop any time, or someone who wants no AI processor in the chain. MacroFactor offers monthly billing, and Cronometer needs no AI to log.
Pricing: Free; PRO is sold as 3- or 12-month prepaid terms with no monthly option, and a 7-day trial is offered at times through the website. (free plan)

#4 MyNetDiary
Free calorie counter with a staff-verified database · United States · mynetdiary.com
Verified foods Free barcode scanner Premium Plus
MyNetDiary says it was founded in 2005, launched as a web app in 2007, and gives a Boca Raton, Florida address. Its pages state that the free tier includes a food diary, barcode scanner, macro tracking, water tracking and a shopping list, with no ads, and that its foods are verified by staff. Premium adds photo-based Meal Scan, structured diet plans, recipes and fasting; Premium Plus adds features for people on weight-loss medication. A free barcode scanner and a verified database are the two features that decide most buyers' first week, and it gives both.
Where it falls short
Most of the claims on its pages, including the 'best free calorie tracker' framing and the comparisons with MyFitnessPal and Lose It!, are published by the vendor about its own product. The tier structure of Premium, Premium Plus and PlateAI takes a few minutes to understand, and no price appeared on the pages we read. Its address is in Florida while its terms cite New York law.
Wrong for
A buyer who wants independent proof of accuracy, or a European who prefers a controller under EU law. Cronometer shows a comparable database, and YAZIO has a European controller.
Pricing: Free tier; Premium and a higher Premium Plus tier add photo logging, diet plans and recipes. We read no list prices on its pages. (free plan)

#5 Snapkin
Photo-only calorie and protein tracker from Belgium · Belgium · getsnapkin.app
EU-hosted server No ads Photo logging
Snapkin is a photo-first tracker whose legal pages read like a plain account of what happens to a meal. The terms and privacy notice name Robot Studios IT Consultancy BV in Berlaar, Belgium, with an enterprise number and VAT number. The notice says the server holding your data is in Amsterdam, in the EU, and that there are no ads and no analytics. It also says the photo analyser runs in the United States through OpenRouter, Google and OpenAI. One plan includes the coach, the widget and every language. The vendor reports a test on 500 weighed meals, with a typical meal within 17 percent of the scale.
Where it falls short
The company is new: its pages carry September 2026 dates and the app is still building a track record. There is no free version, only three free days. The accuracy figures come from the vendor's own test. The data stays in Amsterdam but photos are sent to US processors for analysis, which the notice states openly. The pages we read did not describe a diary export, only account deletion.
Wrong for
A user who wants a free tracker or a database of packaged foods to scan by barcode, or a buyer who wants analysis to stay inside the EU. Cronometer or MyNetDiary give a free scanner.
Pricing: No free version; 3 days free, then EUR 9.99 per month or a yearly plan listed at EUR 49.99, shown beside a struck-through EUR 99.99 as a launch price. (free trial)

#6 MyFitnessPal
Mass-market calorie counter with a large device network · United States · myfitnesspal.com
Largest user base 35+ device syncs Premium paywall
MyFitnessPal is the incumbent, and its main asset is reach: the premium page says more than 35 apps and fitness devices sync with it, including Apple Watch, Fitbit, Garmin and Samsung Health. The free plan covers basic nutrition, weight and exercise tracking, and Premium costs 49.99 euros a year with a 7-day trial. For someone who already has years of history in it, or whose gym or tracker already connects to it, staying is a reasonable decision. It sits sixth because a new user gets less free here than at the smaller products above it.
Where it falls short
By the vendor's own premium page, barcode and meal scanning, voice logging, custom macro goals and an ad-free experience belong to Premium. That means a free user types foods in by hand and sees ads. The controller is a Texas company with a data protection representative named for the EU, and its privacy policy says processing takes place in the United States and through providers around the world.
Wrong for
A new user who wants a free barcode scanner, or one who wants an EU controller. MyNetDiary's free tier includes a scanner, and YAZIO is German.
Pricing: Free plan; Premium is listed at 9.99 euros per month or 49.99 euros per year, each with a 7-day free trial. (free plan)
Visit MyFitnessPal →
#7 Lifesum
Swedish nutrition app with meal plans and AI logging · Sweden · lifesum.com
Swedish company Meal plans AI tracking
Lifesum's helpdesk lists what Premium unlocks: AI tracking, your own calorie and macro goals, meal plans developed by nutritionists such as a three-week weight loss plan, intermittent fasting and a one-week vegan plan, plus the recipe library and nutrient detail. The privacy policy names Lifesum AB with a Swedish registration number and a Stockholm postal address, says Swedish law and courts apply to the terms, and lists the right to data portability. Multimodal logging by photo, voice, text and barcode is advertised on its home page. It suits a user who wants structure handed to them, not a blank diary.
Where it falls short
Setting your own daily calorie goal sits behind Premium according to its helpdesk, which is a basic control. AI tracking is also Premium. The policy says personal data may be transferred outside the European Economic Area under the EU-U.S. Data Privacy Framework or standard contractual clauses. No price appeared on the pages we read, and cancellation must be done at the store where you bought.
Wrong for
A user who wants to set a calorie target on a free plan, or who wants a published price before downloading. Cronometer and YAZIO both give more in the free version.
Pricing: Free version; Premium is an auto-renewing subscription sold through app stores and the website, with no list price on the pages we read. (free plan)

#8 Foodvisor
French nutrition app with professional coaching · France · foodvisor.io
French company Coaching 14-day trial
Foodvisor's terms of service identify Foodvisor SAS, registered in Paris under number 812 516 847, with a registered office at 40 bis rue Violet. They describe a free version and a Premium Account that adds personalized coaching by a nutrition professional, the one human-coaching offer in this ranking. The terms also describe a 14-day trial, payment through the App Store, Google Play or its website via Stripe, and prices displayed in local currency with tax included. For someone who wants a person reviewing their eating inside the app, that is a clear offer from a European controller.
Where it falls short
No price figure appears in the terms or the pages we could read, because prices are shown in the app itself. Its privacy policy page loaded without content for us, so we cannot report hosting or retention. The terms describe coaching but we did not verify the credentials of the coaches or how many users each handles. Customer service is reached by post and email.
Wrong for
A user who wants the price before installing, or who wants verified hosting details. MacroFactor and Snapkin publish prices, and YAZIO states its hosting.
Pricing: Free version; Premium price is shown in the app in local currency, tax included, with a 14-day trial referred to in its terms. (free plan)

#9 Fitatu
Polish calorie counter with menus and a UK database · Poland · fitatu.com
Polish company Diet menus UK food database
Fitatu S.A. identifies itself in its privacy policy as the data controller, with a registered seat in Poznan, a named data protection officer and a section on the right to data portability under the GDPR. Its English page describes a large database of British products, including items from supermarkets such as Tesco, Sainsbury's and Aldi, plus one-click adding, remembered portions and menus for balanced, vegetarian, low-sugar, keto, gluten-free and high-protein eating. One of the few trackers here that targets both the UK and Poland, it earns a mid-table place on that localization and its free version.
Where it falls short
The privacy policy we read is in Polish, which a UK user will find hard to check. It names tools from Google Ireland, Meta Platforms Ireland and others for analytics and login. We did not record paid prices, and the ratings on its English page carry a 2024 update date. Its coverage of other European countries is not described on the pages we read.
Wrong for
A user outside Poland and the UK, or one who needs the legal documents in English. YAZIO and Lifesum publish English notices and cover more markets.
Pricing: A free version exists per its pages; paid tiers are named Premium and Premium+AI, and we did not record list prices. (free plan)

#10 Nutracheck
UK calorie counter built on British foods · United Kingdom · nutracheck.co.uk
UK foods Barcode app Community forum
Nutracheck describes itself as the UK's top-rated diet website and builds its pitch on UK foods with photos and a barcode scanning app, plus a web diary and a member forum. Its terms name NutraTech Ltd, registered in England under number 5093196, and state that new users have the app and site free for seven days, after which restrictions apply unless a subscription is bought. The privacy policy cites UK GDPR, gives a Nottingham address for the data protection officer and says accounts unused for three years are deleted. For a British shopper it is a focused tool.
Where it falls short
There is no lasting free tier, only the seven-day trial, and we read no membership price. The terms say the service is for adults over 18 and should not be used by pregnant women. Its registered office is in London while it trades from Nottingham. The database is built for UK foods, so a user elsewhere will find less value.
Wrong for
Anyone outside the UK, under 18 or pregnant, or a user who wants a free plan. Cronometer and YAZIO both keep a free tier.
Pricing: 7 days free, after which restrictions apply; membership options are bought in the app or on the website, and we did not read a price. (free trial)
Visit Nutracheck →
#11 SnapCalorie
Photo and voice calorie tracker with free core features · United States · snapcalorie.com
Free core Photo logging Voice logging
SnapCalorie's home page says to snap a photo and get nutrition information, offers hands-free voice logging, a free meal planner, and states core features are free forever with no credit card. The privacy notice names PerceptionLabs, Inc., doing business as SnapCalorie, and the terms describe a free trial with one trial per person. It also publishes a research page and an API page. For a user whose main wish is to avoid typing and not to pay at first, the combination is attractive.
Where it falls short
Little on its pages describes the food database, nutrient depth, export or hosting, so a buyer cannot compare it with the others on those tests. The terms mention paid subscription charges but no figure appeared. Its privacy notice is a generic template that lists a post address in Virginia for the data protection contact. Accuracy depends on photo estimates, which no vendor here can guarantee.
Wrong for
A user who needs micronutrients, a verified database or an exportable diary. Cronometer is the stronger choice for detail.
Pricing: Core features free with no credit card; the terms describe a free trial and subscription charges for paid features, with no price on the pages we read. (free plan)
Visit SnapCalorie →
#12 Eat This Much
Automatic meal planner with food tracking · United States · eatthismuch.com
Meal planner Grocery lists $5 Premium
Eat This Much generates a day of meals to hit your calorie and macro targets, and lets you track what you ate, add foods from barcodes, create custom foods and schedule recurring ones on a free plan. Premium at $5.00 a month, the lowest list price in this ranking, adds automatic grocery lists, delivery integration and PDF or email sharing of plans. Its terms identify Eat This Much, Inc., a Delaware corporation, and its pages include a section for professionals. If your problem is deciding what to cook, not recording it, it addresses that directly.
Where it falls short
It plans first, so logging is not its center, and the tools for a quick diary are thinner than at the trackers above. The grocery list, which many users come for, sits in Premium. The terms give a Redondo Beach address as the designated agent's, and we did not read hosting or export details.
Wrong for
A user who wants a fast, detailed food diary with a deep verified database, or a European who needs an EU controller. Cronometer and YAZIO fit better.
Pricing: Free plan at $0; Premium is listed at $5.00 per month. (free plan)

What the data says about this market
Of the twelve products ranked here, five are run from the United States (MacroFactor, MyNetDiary, MyFitnessPal, SnapCalorie and Eat This Much), and one each from Canada, Germany, Sweden, France, Poland, the United Kingdom and Belgium. That spread is wider than in most business software categories, partly because food databases are local: a product built on British supermarket labels or Polish dishes has a reason to exist next to an American one. Nine offer a free plan with no stated end date, three (MacroFactor, Nutracheck and Snapkin) offer only a time-limited trial, and none of the twelve is open source.
Only five of the twelve publish a price on the pages we read: MacroFactor, Cronometer, MyFitnessPal, Eat This Much and Snapkin. The rest say a premium tier exists and show the figure inside the app store listing or at checkout, which makes comparison harder than it needs to be. Pricing practice also splits by billing shape. MacroFactor lists monthly, six-month and yearly terms, Snapkin one plan billed monthly or yearly, YAZIO sells prepaid terms and no monthly plan, and the free tiers of MyFitnessPal and Cronometer carry ads that a paid plan removes.
Two shifts show up across the vendor pages. First, photo and voice logging have become a headline feature at Snapkin, MacroFactor, YAZIO, Lifesum, SnapCalorie and MyNetDiary, which moves effort from typing to correcting. Second, vendors now describe their data practices in more detail than they did a few years ago: four of the twelve name a specific AI or cloud processor in their notices. Neither shift removes the older question of whether the database behind the number is checked by a person.

Questions and answers
What is the best nutrition tracking app in 2026?
Cronometer takes first place in this ranking because it pairs a free plan with a database of over a million lab-analyzed or verified foods and a paid tier that costs $59.99 a year. MacroFactor is the better pick for someone who wants weekly target adjustments and will pay $71.99 a year with no ads. YAZIO is the better pick for a European user who wants a German controller, a free calorie counter and optional AI photo logging. MyFitnessPal has the largest user base but sits lower because the free plan lacks barcode scanning.
Is there a nutrition tracker that is free and still useful?
Yes, nine of the twelve have a free plan, but the limits differ. Cronometer's free version includes barcode scanning and the full food database but shows ads. YAZIO says all calorie-counting functions stay free and withholds recipes and extended statistics. MyFitnessPal's free plan covers basic nutrition and weight tracking, with barcode scanning, voice logging and ad removal in Premium. SnapCalorie states core features are free forever. MacroFactor has no free version at all and says it never will; Snapkin offers three free days and then a single subscription.
How accurate are the calorie numbers in these apps?
They are only as good as the entry behind them. Cronometer describes its database as lab-analyzed or verified, MacroFactor offers a verified food search, and MyNetDiary says its foods are staff-verified. Crowd-fed entries and photo estimates carry larger errors, which you can reduce by weighing portions and choosing branded barcode entries. None of the vendors we read states an error rate that we could check, so treat any app's total as an estimate.
Which app is best for building muscle or cutting weight?
MacroFactor is built around that case. It describes a weight trend algorithm and dynamic weekly adjustments to your calorie and macro targets, with bulk, cut and maintenance modes. Cronometer suits the same user who wants micronutrient detail. A plain calorie counter such as Nutracheck or Fitatu gives you a number but leaves the weekly adjustment to you.
Do these apps work for people in Europe?
Several are European: YAZIO in Germany, Lifesum in Sweden, Foodvisor in France, Fitatu in Poland, Snapkin in Belgium and Nutracheck in the United Kingdom. The practical question is the food database. Nutracheck is built on UK foods with photos, and Fitatu's English page describes British supermarket products. MacroFactor's own FAQ says branded product and barcode coverage is expanding in Europe, so test your local groceries before paying.
What happens to my diary if I cancel?
Practice varies and some notices are silent. MacroFactor says you can export or delete your data in the app, and it keeps your personal data for as long as the account exists regardless of subscription status. Nutracheck deletes accounts after three years without use. Cronometer says it may delete accounts with no activity for 36 months. Before canceling any app, look for an export option and download your history.
Is it safe to log health conditions in a calorie app?
Safety depends on the vendor's controls, which a notice only partly shows. Read where the data is stored and who the processors are. Cronometer names US servers, MacroFactor names Google Firestore in the USA, and YAZIO names a German web host and OpenAI Ireland for AI features. Do not enter conditions you would not share with a US or EU cloud provider, and use the app's deletion option when you stop.
What does AI photo logging add, and what does it cost?
It replaces typing with a photo, a voice note or a label scan, then asks you to confirm. Snapkin, MacroFactor, YAZIO, Lifesum, SnapCalorie and MyNetDiary all describe such a feature. At Lifesum, AI tracking is listed under Premium, and at MyNetDiary Meal Scan is part of the paid tier. The cost beyond the subscription is a second processor: YAZIO names OpenAI Ireland and says inputs are not used to train its models.
Can a dietitian or coach use these apps with clients?
Some can. Cronometer's privacy notice describes cases where a school or other organization engages it and it acts as a processor, and mentions professionals acting on a user's behalf. Foodvisor's terms describe personalized coaching by a nutrition professional under a Premium account. Eat This Much has a page for professionals. Most others are sold to individuals, so ask the vendor about shared access and a data processing agreement before you onboard clients.
Is a meal planner the same thing as a calorie tracker?
No. A tracker records what you ate; a planner proposes what to eat. Eat This Much generates daily meal plans from your targets and also lets you track foods and scan barcodes, with its grocery list and PDF sharing in the paid column. Lifesum and Fitatu add menus and plans to logging. If your difficulty is deciding dinner rather than recording it, start with a planner.
Why is MyFitnessPal not first?
It has the broadest reach, but this ranking weighs what a new user gets for free. MyFitnessPal's premium page lists barcode and meal scanning, voice logging, custom macro goals and ad-free logging as Premium items, at 9.99 euros a month or 49.99 euros a year. Cronometer and MyNetDiary give barcode scanning for free. For a user who already has years of history in MyFitnessPal and values its 35-plus device connections, staying is reasonable.
