Best Calorie Tracker App for Eating Out: 7 Apps Compared

The best calorie tracker app for eating out depends on where you eat. At big chains, an app with a large restaurant database gives you the restaurant’s own numbers. At independent restaurants, takeaways and food trucks, you need an app that estimates from a photo of your plate or of the menu.

We make MacroScout, one of the apps below, so keep that in mind as you read. Everything we say about the other apps comes from their App Store and Google Play listings, which we checked on October 20, 2026. We haven’t tested the other apps ourselves, and we leave out prices and ratings because they change often and differ by country.

Quick picks: the best calorie tracker app for eating out, by situation

• You mostly eat at chains and want a free app: MyFitnessPal. Its listing says you can log from 20.5 million foods, including restaurant dishes. Barcode scan, meal scan and voice logging are part of Premium.
• You eat at US chains and want an app run by dietitians: Nutritionix Track. Its listing says the app is developed and maintained by a team of registered dietitians, and its database covers more than 760 US restaurant chain menus.
• You want official chain numbers for the US and UK, checked by a person: Macrotarian. It lists more than 600 brands across both countries, sourced from official restaurant nutrition data, and says nothing in its database is AI-estimated.
• You eat at independent places and want to pick a dish before you order: MacroScout or LeanMenu. Both read a photo of the menu and rank the dishes for you.
• You’d rather chat than search: Welling. You send a message or a photo and it estimates calories and macros. Its listing says you need a subscription to use it.

At a big US chain you may not need an app to choose: our high-protein fast food guide ranks orders at five chains from their official nutrition data.

The 7 apps compared

App	Restaurant data	Menu scan	Photo of your plate	Free version	Platforms
MacroScout	Estimates, no database	Yes (Pro)	Yes (Pro)	Yes: barcode, repeat meals, manual entry	iPhone, Android
MyFitnessPal	20.5M+ foods, incl. restaurant dishes	Not in listing	Yes, “meal scan” (Premium)	Yes	iPhone, Android
Lose It!	56M+ items and recipes; restaurants not mentioned	Not in listing	Yes (Premium)	Yes: calorie tracking, weight plan	iPhone, Android

Macrotarian	600+ US and UK brands, official data	Not in listing; you browse its menus instead	Yes, for food not in its database	Not stated; starts with a free trial	iPhone, Android
Welling	Estimates from chat or photo	Not in listing	Yes	No, subscription needed	iPhone, Android
LeanMenu	Estimates from a menu photo	Yes, free with ads	Not in listing	Yes: menu scans with ads	iPhone, Android

“Not in listing” means the store listing doesn’t mention the feature. The app may still have it, so check before you choose.

MacroScout works differently from the database apps. Its menu scan checks each dish against the calories and protein you have left today and shows the three that fit best. Estimates are adjusted upward for restaurant cooking, and if you share a platter you can log a quarter, a third, a half or the whole dish.

Chain restaurant or local place? It changes which app is best

Where you eat decides how good your number can be.

Where you eat	Best source of the number	What you get
A US chain with 20+ locations	The menu itself, or an app with that chain’s data	The restaurant’s own figure
A large food business in England	The menu itself, or an app with that chain’s data	The restaurant’s own figure
An independent restaurant or takeaway	A photo or menu scan estimate	An estimate, so round up for oil and butter
A home-cooked or family meal	A photo estimate, or log the recipe	An estimate

In the US, the FDA’s menu labeling rules apply to restaurants that are part of a chain with 20 or more locations. They must show calories for standard items on menus and menu boards, and give you written nutrition information if you ask, including fat, sugars, fiber and protein.

In England, food businesses with 250 or more employees have had to show calories since April 6, 2022.

So at a big chain, any app with that chain’s data gets you the restaurant’s own figure, and you can even type in the posted number yourself. The hard case is the local curry house, taqueria or café with no numbers on the menu. That’s where photo and menu scan apps help most, and where their estimates matter most.

How accurate are photo and menu estimates?

They’re estimates, and the apps say so. LeanMenu’s listing says its numbers are AI estimates from a photo of the menu, not lab measurements. Macrotarian makes the opposite pitch: verified chain data, with nothing in its database AI-estimated.

Portion size and restaurant cooking are the usual reasons estimates miss. You can’t see the oil in a curry, the butter on a steak or the sugar in a sauce. A few habits help, whatever app you use:

• Use estimates to compare dishes, not to count to the last calorie. Knowing that one dish is a few hundred calories lighter than another is the useful part.
• Round up rather than down for fried food, creamy sauces and anything glossy with oil.
• When you share plates, log your share, not the whole dish.
• At chains, check the posted calories first.

To see how much one dish can vary, look at our breakdowns of chicken tikka masala, fish and chips and a Chipotle bowl.

Want an app that reads the menu?

If you mostly eat at places without posted calories, a menu scanner is the feature to look for. We compare six menu apps, including what each scan shows and which ones flag allergens, in our guide to restaurant menu scanner apps. You can also see how the menu scan works on the MacroScout page.

How we compared these apps

We read each app’s US App Store listing and looked it up on Google Play on October 20, 2026. We chose apps that either have restaurant data or estimate restaurant meals. For each one we describe what the listing says it does, and we flag where a feature isn’t mentioned. We didn’t run accuracy tests, so we don’t rank the apps by accuracy.

These apps change fast. Two menu scanning apps that still showed up in web search results on October 18 had been removed from the App Store two days later. Check an app’s last update date before you pay for it.
