Best Restaurant Menu Scanner App: 6 Apps Compared

A restaurant menu scanner app reads a photo of a menu and estimates the calories and macros of each dish, so you can choose before you order. Apps that do this today include MacroScout, LeanMenu, CalNote, MenuAI and MacrosMap, and MenuFit suggests what to order even when the menu shows no calories. They all estimate, so they’re best for comparing dishes, not for exact counting. If you want an app that tells you what to order, pick one that ranks the dishes against your own calories and protein, such as MacroScout or LeanMenu.

We make MacroScout, so we’re not neutral. The facts about the other apps come from their App Store and Google Play listings, checked on October 20, 2026. We haven’t tested the other apps ourselves, and we leave out prices and ratings because they change and differ by country.

How menu scanning works

You take a photo of the menu. The app reads the dish names and descriptions, works out what each dish probably contains, and estimates calories, protein, carbs and fat for a typical restaurant portion. Some apps then compare each dish with what you have left for the day and sort the menu for you.

The estimate can only be as good as the menu’s wording. “Chicken curry” tells an app much less than “chicken tikka masala with cream and butter, served with pilau rice”. Short menus with plain dish names leave more to guesswork.

“Not in listing” means the store listing doesn’t mention it. We didn’t find CalNote or MenuAI on Google Play when we checked.

A few differences stand out:

• MacroScout shows the three dishes that fit best, labeled Best fit, Good fit and Also fits. It adjusts estimates upward for restaurant cooking, says when it’s unsure about a dish, and discards your menu photo after the scan.
• LeanMenu is built only for choosing at the table. Its listing says it won’t log every bite, so you’d pair it with a tracker if you count calories all day.
• MenuAI and MacrosMap mix a scan with a database of restaurant items, so for some places you can look dishes up instead of scanning.
• MenuFit doesn’t mention scanning in its listing. It suggests what to order for your goals, with calorie and macro breakdowns.

Menu scan or verified chain data?

A scan is the tool for places that don’t publish numbers. At chains, the restaurant’s own data is better than any estimate.

In the US, restaurants in chains with 20 or more locations must show calories on their menus and menu boards, and give written nutrition information if you ask. In England, food businesses with 250 or more employees have had to show calories since April 6, 2022. Apps like Macrotarian go further and collect official chain data for the US and UK, which its listing says is checked by a person, with nothing AI-estimated.

So use posted or verified numbers at chains, and a menu scan at the independent pizzeria, curry house or taqueria. For a sense of how much one order can vary, see our breakdowns of a Chipotle bowl and tacos al pastor. At McDonald’s, Burger King, Subway, Starbucks and Chipotle, our high-protein fast food guide ranks orders using each chain’s official numbers.

How to get a better estimate from a menu scan

• Photograph one page at a time, flat and in good light, so every dish is readable.
• Keep the descriptions in the shot, not just the dish names. Words like “fried”, “creamy”, “buttered” and “glazed” change the estimate.
• Tell the app what you’ll actually eat. MacroScout lets you log a quarter, a third, a half or the whole dish when you share.
• Use the ranking to narrow it down to two or three dishes, then ask how they’re cooked.
• Confirm allergens with the staff. Both MacroScout and LeanMenu tell you to do this.
• If an app doesn’t say it accounts for restaurant cooking, round its numbers up yourself. Our breakdown of chicken tikka masala shows how much cream and butter can add.

Check that the app is still maintained

Menu scanner apps are new and change quickly. When we checked on October 20, 2026, two menu scanning apps that web search was still showing two days earlier had been removed from the App Store, and another hadn’t been updated since November 2025. Before you subscribe, look at the last update date on the store page and start with free scans or a trial.
