7 Best Calorie Tracker Apps in 2026 (Free Plans and Prices)

The best calorie tracker app is the one you will still be using in week six, and that depends mostly on how fast logging feels. Of 6,469 meals logged in Bodly, 65% were added by photo, 29% by typing and 6% by barcode. Cronometer has the most accurate free database, MyFitnessPal the biggest, and photo-first apps the fastest logging. Paid plans run from about $39 to $80 a year in the US.

Below are seven apps compared on what is free, what the upgrade costs, how each one logs food, and how far you can trust the numbers.

How accurate are calorie tracker apps?

Two things decide how close your logged calories are to what you actually ate: the food database, and the logging step. The app's brand matters less than either.

The database. Some apps let any user add foods, which gives a huge database with duplicates and mistakes. Others build their database from verified sources such as national food composition tables. In a 2020 validation study, 50 people logged four days of food in MyFitnessPal, and the results were compared with a national food composition database. After removing obviously wrong entries (2.8% of them), MyFitnessPal's totals matched closely for energy (r = 0.96) and for carbohydrates, fat and protein (r = 0.90 each), with no systematic bias. They matched poorly for sodium and cholesterol (r around 0.5). So a crowd-sourced database is fine for calories and macros, as long as you choose entries with care, and weak for micronutrients.

The logging step. Portion size is where most errors come from. A "medium" banana, a "bowl" of pasta and a "splash" of olive oil can each be off by 30 to 100 calories, and a missed cooking oil can be more. Weighing food on a kitchen scale for the first couple of weeks calibrates your eye, and is worth more than switching apps.

Source of error	How big	What to do
Wrong or duplicate database entry	Occasional large errors	Prefer verified entries; check calories per 100 g
Portion estimated by eye	Often 10 to 30%	Weigh food for the first 2 weeks
Cooking oil, sauces, drinks not logged	100 to 300+ kcal a day	Log them first, not last
Photo estimate of a mixed dish	Large, especially sauces and stews	Check the portion after the scan
Micronutrients from a crowd-sourced database	Weak (sodium r about 0.5)	Use a verified database if you track them

Do AI photo calorie trackers work?

Photo logging is now in most of these apps, and it is the fastest way to log. It is also the least precise. A 2024 University of Sydney study tested the most popular nutrition apps against weighed food records. The best AI image recognition identified foods correctly most of the time (MyFitnessPal 97%, Fastic 92%), but the automatic calorie estimates from photos were inaccurate, and mixed dishes and culturally diverse foods were hardest. Manually logged apps were off too, in both directions: they overestimated a Western menu and underestimated an Asian menu.

That matches what people do in practice. In Bodly, 65% of meals are logged by photo because it takes seconds, and the scan does the tedious part: naming the food and pulling up calories and macros. The step that keeps it honest is checking the portion afterwards, which takes one more tap.

Logging method	Speed	Typical accuracy	Best for
Photo	Fastest	Good at what, weaker at how much	Most meals, staying consistent
Barcode	Fast	High for packaged food	Packaged and branded food
Search and type	Slowest	Depends on the entry you pick	Home cooking, precise tracking
Weighed and searched	Slow	Highest	Calibration weeks, strict goals

The 7 best calorie tracker apps

1. Cronometer: most accurate free calorie tracker

Cronometer builds its database from verified sources rather than user submissions, which is why it is the usual recommendation for anyone who cares about accuracy or micronutrients. The free plan covers full food logging, including barcode scanning (photo logging is part of Gold), and syncs with Apple Health, where it can also import weight, body fat and waist measurements.

Choose Cronometer if you want the most trustworthy numbers, including vitamins and minerals. Skip it if you find dense screens tiring; it shows more than most people need.

2. MyFitnessPal: biggest database and the most familiar

MyFitnessPal has the largest food database and the most third-party connections, so almost any branded food is already there. The trade-off is that much of the database is user-submitted, and since October 1, 2022 the barcode scanner requires Premium. The free plan still logs food, exercise and weight.

Choose MyFitnessPal if you eat a lot of branded and restaurant food and want it already in the database. Skip it if you want barcode scanning without paying $79.99 a year.

3. Lose It!: simplest everyday calorie logging

Lose It! is built around a calorie budget and a quick daily routine, which suits people who find detailed nutrition apps overwhelming. The free plan covers searching and logging food against your budget; barcode scanning and photo logging are Premium features. It syncs with HealthKit and connects to Withings scales.

Choose Lose It! if you want the shortest path from meal to logged. Skip it if you want detailed macro and micronutrient analysis.

4. FatSecret: best free plan for logging plus weigh-ins

FatSecret's free plan covers food logging, exercise and a weight log, and it syncs your weight with Apple Health. Premium adds photo food logging, meal plans and water tracking.

Choose FatSecret if you want a useful free plan without upgrade pressure. Skip it if design matters to you; it is more functional than polished.

5. MacroFactor: best for adaptive calorie targets

MacroFactor adjusts your calorie target every week from your logged intake and weight trend, which removes the guesswork of setting a target and wondering whether it is right. There is no free plan, only a trial.

Choose MacroFactor if you want the app to do the maths on your target. Skip it if you want a free calorie tracker.

6. Cal AI: photo-only logging

Cal AI does one thing: you photograph a meal and it estimates calories and macros. It is quick, and scan results require a subscription. Read the accuracy section above before trusting a photo estimate of a mixed dish.

Choose Cal AI if speed is all you want from a calorie tracker. Skip it if you want a free plan or anything beyond food.

7. Bodly: calorie tracking with weight, body and Apple Watch data

Bodly logs meals by photo, text or barcode and shows calories, macros and a nutrition score. What sets it apart is what sits around the food log: weight with a smoothed trend, body measurements, progress photos, and strain, sleep and recovery scores from your Apple Watch. When the scale stalls in a deficit, the waist measurement and photos are usually what show the progress.

Choose Bodly if you want calories, weight and body changes in one app, especially with an Apple Watch. Skip it if you only want a calorie database and nothing else.

Free vs paid: when the upgrade is worth it

You can track calories for free in Cronometer, MyFitnessPal, Lose It! and FatSecret. Pay when a paid feature removes friction you actually feel:

• Barcode scanning if you eat a lot of packaged food and use MyFitnessPal or Lose It! (Cronometer scans barcodes for free).
• Adaptive targets (MacroFactor) if you keep second-guessing your calorie target.
• Photo logging if typing every meal is why you keep quitting.

Do not pay for an app to make up for a target that was never set properly. Work out your maintenance calories first with the TDEE calculator and your protein with the protein intake calculator, then pick the app that makes hitting them easiest.

Does calorie tracking help you lose weight?

Yes, and the habit matters more than the app. A systematic review of 22 studies on self-monitoring (food diaries, exercise logs and weighing) found a significant association between self-monitoring and weight loss in every study that measured it. The authors rated the evidence as weak, because most studies were small, relied on self-report and included mostly white women. The direction is consistent, though: people who keep logging tend to lose more.

Two practical rules follow from that:

1. Log first, judge later. An imperfect log you keep is better than a perfect one you abandon. Photo logging exists for exactly this.
2. Pair calories with the scale's trend. Calories in tell you what you did; a 7-day weight average and your waist tell you whether it worked. If they disagree, calorie deficit but gaining weight covers the usual reasons.

Calorie burn from your watch is the other half of the equation, and it is less precise than most people think: how accurate Apple Watch calories are explains how to use it without overeating.

How to choose

• Choose Cronometer if accuracy and micronutrients matter most.
• Choose MyFitnessPal if you want the biggest database and do not mind paying for barcodes.
• Choose Lose It! if you want the simplest routine.
• Choose FatSecret if you want the most useful free plan.
• Choose MacroFactor if you want your calorie target adjusted for you.
• Choose Cal AI if all you want is a photo log.
• Choose Bodly if you want food, weight, body measurements and Apple Watch data together.

A note on health

Calorie tracking is a tool, not a requirement. If counting makes you anxious, or you have a history of disordered eating, talk to your doctor or a dietitian before you start, and consider tracking habits instead of numbers. Calorie targets below about 1,200 kcal a day for women or 1,500 for men should be supervised.

How we picked these apps

We compared the apps people search for most alongside "calorie tracker", checked each one's US App Store listing for current prices and free-plan limits in October 2026, and weighed them on database quality, logging speed, what the free plan includes, and whether the app fits a distinct type of user. Bodly is our own app; we have described it by what it does, not ranked it first.
