How we make this list: we compare pricing pages, product documentation and public user reviews. Rankite is independent; if a vendor ever pays for a featured spot, that listing is clearly labeled Partner.
Key takeaways
- MyFitnessPal has the biggest food database; Cronometer has the most trustworthy nutrition data. Pick based on whether you eat packaged food or cook from scratch.
- MacroFactor is the only app here with no free plan, but its adaptive calorie targets are the best in the category for lifters.
- FatSecret and MyNetDiary offer the most generous free tiers; Noom is the most expensive because you pay for coaching, not just tracking.
- Accuracy varies more than marketing suggests: a published 180-meal study found calorie errors from 1.1% to 11.2% across six popular apps (technology.org, October 2026).

The best fitness calorie tracker apps
Starting priceSee website
Free planYes
MyFitnessPal is the default calorie tracker for a reason: if you eat it, it is probably in the database. Packaged foods, chain restaurant menus, recipes from 30+ cuisines, the coverage is unmatched, and barcode scanning makes packaged food logging nearly instant. Premium adds voice logging, custom macro goals, an ad-free experience and intermittent fasting tools, with a 7-day free Premium pass to try it.
The honest weakness is data quality. Much of the database is user-submitted, so the same product can appear with several different calorie counts. In a published six-app study of 180 weighed meals, MyFitnessPal averaged the widest calorie error at 11.2% (technology.org, October 2026). If you mostly eat packaged and restaurant food, the convenience outweighs that. If you need precise numbers for medical reasons, Cronometer's verified data is the safer bet.
What we like- Over 20 million foods plus restaurant menus
- Barcode scan and meal photo logging
- Syncs with 40+ apps and devices
Watch out for- Free tier is ad-supported with key features paywalled
- User-submitted entries vary in accuracy
- Premium price has crept up over the years

Free planYes
Cronometer is the tracker for people who care what is in the food, not just how many calories it has. Every entry is checked against verified sources like the USDA and NCCDB, and Gold tracks up to 95 nutrients and compounds, from vitamin D to magnesium. The free tier is unusually generous: barcode scanning, macro tracking and custom targets cost nothing.
Gold adds photo logging, voice logging, a fasting timer, Oracle nutrient search and custom biometric tracking. The trade-off is database size: with far fewer entries than MyFitnessPal, obscure packaged foods may be missing. For whole-food eaters, athletes watching micros, and anyone tracking for health reasons, it is the most accurate option here.
What we like- Lab-analyzed data from USDA and NCCDB
- Tracks up to 95 nutrients on Gold
- Free barcode scanning and a strong free tier
Watch out for- Smaller food database than MyFitnessPal
- Free tier shows ads and limits history to 7 days
- Photo logging needs Gold

Lose It! takes the opposite approach from Cronometer: instead of more data, it gives you one number, your daily calorie budget, personalized from your age, height, weight and goal, and makes staying inside it fast. Log by barcode, photo, voice or search, and the app keeps score. It has been around since 2008 and the formula still works.
Premium adds macro goals, meal planning, patterns and reports, and device integrations. The free tier covers the core loop well, which is why adherence-focused reviewers keep recommending it to beginners. If you want deep nutrient analysis, look elsewhere. If you want the simplest path to eating less, this is it.
What we like- Personalized daily calorie budget
- Snap It photo and Say It voice logging
- Friendly interface that beginners stick with
Watch out for- Nutrition detail is thinner than Cronometer
- Some useful reports are Premium-only
- Smaller ecosystem than MyFitnessPal

MacroFactor is built for people who lift. Its defining feature is the adaptive expenditure algorithm: it watches your logged intake against your weight trend and adjusts your calorie and macro targets at weekly check-ins. No other app here does this as well, and in the six-app weighed-meal study it posted the second-lowest calorie error at 4.8% (technology.org, October 2026).
There is no free tier, only a 7-day trial, and the subscription is priced for committed users. Casual dieters will find it more complex than they need. But if you are running a months-long cut or bulk and want your targets to adapt instead of staying static, it is the best coaching algorithm in the category.
What we like- Algorithm adjusts calorie and macro targets from your weight trend
- Excellent for long cuts and bulks
- Strong food database
Watch out for- No free plan, only a 7-day trial
- Overkill for casual dieters
- Interface assumes you know what macros are

Free planYes
Yazio pairs calorie tracking with intermittent fasting in one clean interface, which is its real differentiator. Set your fasting window, log meals with the AI scan or barcode reader, and the app keeps both on track. PRO adds the full fasting plans, recipes and advanced stats.
The free tier works but carries ads and holds back the better features. European users will find the food database stronger for local products than the US-centric apps. It is a good middle-ground pick: friendlier than Cronometer, more focused than MyFitnessPal, with fasting built in rather than bolted on.
What we like- Clean design with strong fasting tools
- AI food scan and barcode logging
- Affordable PRO tier
Watch out for- Free tier is ad-supported
- Food database is smaller than the leaders
- Nutrition detail lags Cronometer
Starting priceSee website
Free planYes
Lifesum sells structure. Instead of handing you a blank diary, it offers diet programs, meal plans and habit tracking wrapped in one of the nicest interfaces in the category. For people who do better following a plan than building one, that guidance matters more than database size.
The free tier lets you test the basics, but the plans, recipes and deeper insights sit behind the subscription. It does not match Cronometer for data rigor or MacroFactor for adaptive coaching. What it does is make healthy eating feel guided and pleasant, and for many users that is what keeps them logging in week six.
What we like- Structured diet plans and meal plans
- Polished design people enjoy opening
- Barcode and photo logging
Watch out for- Free tier is limited
- Nutrition science is lighter than Cronometer
- Subscription needed for the best features
Starting priceSee website
Free planYes
FatSecret is the quiet value pick. The free tier includes food logging, barcode scanning, exercise tracking and community features without constantly pushing you toward a paid plan. Premium exists and adds extras like smart food scan, but the free app is a complete tracker on its own.
The interface looks dated next to Lifesum or Yazio, and the database leans on user submissions. But if your budget is zero and your goal is simply to log honestly every day, FatSecret asks nothing and delivers the essentials. It is also one of the few apps here with a real community feel, including challenges and groups.
What we like- Genuinely free core tracking including barcode scanning
- No aggressive upsell
- Community and challenges built in
Watch out for- Dated interface
- Smaller verified database
- Premium features are thin compared with rivals
Starting priceSee website
Free planYes
MyNetDiary is the most balanced app on this list. Its food database is verified rather than crowdsourced, the free tier has no ads and keeps unlimited history, and Premium adds meal photo scanning, intermittent fasting, premium diets designed by dietitians, and medication tracking. A Premium Plus tier adds an AI coach and restaurant menu scanning.
It does not have MyFitnessPal's database size or Cronometer's nutrient depth, but it avoids both apps' weaknesses: no ads, no dubious entries, no stripped free tier. For someone who wants a trustworthy all-rounder without paying, the free tier is arguably the best deal in the category.
What we like- Verified food database with no ads on free tier
- Unlimited history even free
- Premium adds meal scan, fasting and diet plans
Watch out for- Premium Plus tier needed for the AI coach
- Smaller brand recognition
- Restaurant coverage trails MyFitnessPal
Starting priceSee website
Free planFree trial
Noom is not really a tracker that added coaching; it is a coaching program that includes tracking. Daily lessons on habits, psychology and behavior change, plus a human coach, are the product. The food logging exists to support the program, not to compete with Cronometer.
That positioning explains the price, which runs several times higher than a typical tracker subscription. There is no free plan, only trial and intro offers. If you have tried pure trackers and quit them, Noom's structure may be what was missing. If you just want to count calories accurately and cheaply, every other app on this list does it for less.
What we like- Behavior-change coaching built around psychology
- Structured program with lessons
- Strong accountability features
Watch out for- The most expensive option here
- Tracking tools are weaker than dedicated trackers
- No meaningful free tier
What to look for in a calorie tracker
The app you will still open in week six beats the app with the best specs. Keep that in mind while you compare.
Logging friction
Photo, voice and barcode logging are not gimmicks; they are the difference between logging dinner and skipping it. MyFitnessPal, Lose It!, Yazio and Lifesum all offer photo logging, usually on paid tiers. FatSecret and MyNetDiary keep more of it free. Try the free tier first and count how many taps a meal takes.
Database vs data quality
A huge database (MyFitnessPal) means your food is probably listed. A verified database (Cronometer, MyNetDiary) means the numbers are probably right. You cannot have both at the extremes, so pick based on what you eat: packaged and restaurant food favors size, home cooking favors verification.
Device integrations
If you train with a watch or scale, check sync before you commit. MyFitnessPal connects with 40+ apps and devices. Cronometer syncs with Fitbit, Garmin, Apple Health and others on the free tier. A tracker that cannot see your workouts is a tracker you will fight with.
Data export and history
Cronometer's free tier limits history to 7 days; MyNetDiary keeps it unlimited. If you ever want to analyze your own data or switch apps, export options matter. Check the plan details for CSV or PDF export before you build a year of history somewhere.
Free vs premium: what you actually get
Free tiers in this category are genuinely usable, which is good news. FatSecret, MyNetDiary and Cronometer all let you track calories and macros without paying. What premium buys is convenience and depth: photo and voice logging, ad removal, fasting timers, meal plans, AI coaching and longer history. The pattern is consistent: the core loop is free, and the subscription removes friction around it. Start free for two weeks. Pay only when you hit a specific limit that annoys you, not because the app suggests it.
How we chose
We focused on apps that exist today on iOS and Android and are built around calorie and nutrition tracking. We opened each vendor's homepage to verify the product and its current positioning, checked pricing and plan pages where they rendered, and compared feature lists, free-tier limits and device integrations. We cross-checked claims against documentation and public reviews on the App Store, Google Play, G2 and Reddit, plus published accuracy testing (the Dietary Assessment Initiative's 180-meal study via technology.org). We did not run hands-on testing; this comparison rests on published specs, plan terms and long-term user feedback.
Frequently asked questions
Which calorie tracker app is the most accurate?
In the Dietary Assessment Initiative's published study of 180 weighed meals, the AI photo logger PlateLens averaged 1.1% calorie error, followed by MacroFactor at 4.8% and Cronometer at 6.8%, with MyFitnessPal widest at 11.2% (technology.org, October 2026). Among the apps on this list, Cronometer's verified database and MacroFactor's adaptive approach score best.
Is there a completely free calorie tracker?
FatSecret and MyNetDiary come closest: full food logging, barcode scanning and exercise tracking at no cost, with MyNetDiary adding no ads and unlimited history. Cronometer's free tier is strong too, though it shows ads and limits history to 7 days.
Do I need to pay to lose weight with an app?
No. The free tiers of Lose It!, FatSecret, MyNetDiary and Cronometer cover the core loop: set a target, log food, watch the trend. People pay for convenience features like photo logging and meal plans, not for the weight loss itself.
Can these apps sync with my fitness watch?
Most of them. MyFitnessPal, Cronometer, MyNetDiary, Yazio and Lifesum all sync with Apple Health, Google Health Connect, Fitbit or Garmin to varying degrees. Check the specific integration list on the vendor's site for your device before subscribing.
Which app is best for keto or low-carb diets?
Cronometer and MacroFactor handle macro-focused diets best, with detailed nutrient tracking and custom macro targets. Carb Manager is a keto-specific alternative worth a look if every app here feels too general.
Will a calorie tracker sell my data?
Policies vary, so read the privacy policy of the app you choose. Cronometer states it encrypts data and enforces strict access controls. As a rule, prefer apps with clear privacy policies and paid tiers, since ad-supported free apps have more incentive to monetize usage data.
