Best Calorie Counter App for Weight Loss? 6 Apps Compared (2026)

This article is for educational purposes only and is not medical advice. Talk with a qualified healthcare professional before making major nutrition, weight loss, or medication-related changes.

There is no single best calorie counter app for weight loss. The right one depends on how you like to log food, how much nutrition detail you want, and what you will pay for. We compared six widely used apps, Kalo, MyFitnessPal, Lose It!, Cronometer, MacroFactor, and Cal AI, using each app's official store listing and website, checked September 24, 2026.

Disclosure: Kalo publishes this website and makes one of the apps below. Every feature in this comparison comes from the app's own official listing or website, including Kalo's, and we note where another app is the better fit. We did not run hands-on accuracy tests, and this page does not claim that any app leads to more weight loss than another.

Quick picks by what you need

Free logging with a huge food database: MyFitnessPal or Lose It!. Both have free tiers, with faster tools like barcode and photo logging in their paid plans.
Free barcode scanning and deep nutrient detail: Cronometer.
Targets that adjust week to week: MacroFactor, if you are fine paying after a 7-day trial.
Photo-first logging: Cal AI, with a subscription for scan results.
Daily targets, ideas for what to eat next, and room for bigger weekend days: Kalo, which requires a subscription.

How do the top calorie counter apps compare?

This table uses each app's official App Store listing, plus the MacroFactor and Cal AI websites where the listing did not name every logging method. Plans and features change, so check the store screen before you subscribe.

The listed connection is Apple Health active energy.
MyFitnessPal	Food search (20.5M+ foods listed, including restaurant dishes), barcode scan, meal scan (photo), voice	Free tier for logging and goals.

All six apps are available on iPhone and Android. Food database sizes are the numbers each company lists, not independent counts, and a bigger database is not the same as a more accurate one.

Which calorie counter app should you choose?

Start with how you eat and how you want to log, not with a ranking. These are the situations where each app fits well:

You eat a lot of packaged and chain-restaurant food. A large searchable database and barcode scanning matter most. MyFitnessPal and Lose It! list the largest databases. Cronometer includes barcode scanning in its free tier.
You want to track vitamins and minerals, not only calories. Cronometer lists 95+ vitamins and minerals and is built around that detail.
You already log consistently and want your target to adapt. MacroFactor adjusts calorie and macro targets at weekly check-ins based on what you log, instead of keeping one fixed number.
Searching a database is what makes you quit. Look at apps that let you describe a meal or take a photo, then edit the result. Kalo, Cal AI, MacroFactor, Cronometer Gold, Lose It! Premium, and MyFitnessPal Premium all list some form of this.
You want a daily plan and help deciding what to eat next. Kalo sets calorie, protein, carb, fat, and fiber targets and suggests meals based on your goals, your preferences, and what you have left for the day.
You eat more on weekends. Kalo lets you choose higher-calorie days, such as Saturday and Sunday, and lowers your other days so your weekly total stays the same.
You want to spend nothing. Stick to the free tiers of MyFitnessPal, Lose It!, or Cronometer and log by search. Kalo, MacroFactor, and Cal AI need a subscription.

Does the app matter as much as logging consistently?

Usually not. In a 24-week online weight-loss program with 142 adults, participants who reached 5% or 10% weight loss opened their food journal more times per day than those who did not, and the time spent logging fell from about 23 minutes a day in month one to about 15 minutes in month six (Harvey et al., Obesity, 2019). That is an association in one program with a web-based journal. It does not show that any particular app works better, but it does suggest that frequent, easy logging is what to optimize for.

The practical test: before paying, log one normal weekday in the app you are considering. Include a rushed breakfast, a restaurant or takeout meal, a packaged snack, and a home-cooked dinner. If the app handles all four without a fight, it is a serious contender. If one meal takes several minutes, that friction will add up.

What should you check before you subscribe?

Which features are actually free. Several apps list barcode, photo, or voice logging as paid features. Check the plan screen, not just the feature list.
Trial and renewal terms. Trial length, price, and renewal are shown in the App Store or Google Play purchase screen and can vary by country and account.
Whether you can edit estimates. Photo and description logging give you an estimate. You should be able to change foods, portions, oils, and sauces before saving.
How the calorie target is set. A target should come from your details and goal, and you should be able to change it.
Privacy and data controls. Food logs and weight history are personal. Read the privacy policy and look for export and delete options.

Are AI photo calorie estimates accurate enough?

They can be a useful starting point, but they are estimates. A photo cannot show hidden oil, the depth of a bowl, or what is inside a wrap, so reviewing the result matters more than the brand of AI. For packaged foods, a barcode or the label is usually the better source. Our reviews of how accurate AI calorie counters are and what the evidence says about Cal AI explain why a company's own accuracy claim is not the same as independent testing.

Who should be careful with calorie counter apps?

Calorie counter apps are tools, not medical care. If you have a history of disordered eating, are pregnant, are managing a medical condition, or feel anxious when tracking food, talk with a qualified clinician or registered dietitian before using a tracking app. The goal is better awareness, not a smaller number at any cost.

Where Kalo Fits

Kalo is built around a daily plan: personalized calorie and macro targets, a weekly schedule that can give weekends more room, logging by describing what you ate, and meal ideas based on your goals, your preferences, and what you have left. You review the foods, portions, calories, and macros before anything is saved. Kalo requires a subscription, so if you want free tracking or deep micronutrient reports, one of the apps above may suit you better. If you want targets, a plan for bigger days, and help deciding what to eat next in one place, Kalo is worth a try.
