Best Food Scanner Apps (2026–2027)

Two kinds of food scanner app

Search for a food scanner app and you will find two different products sharing one name. Knowing which one you need saves you an install.

• Nutrition scanners answer “what did I eat, and how much?” You scan a barcode or photograph a plate, and the app logs calories, protein, carbs, fat and, in the better ones, vitamins and minerals into a daily diary. PlateLens, MyFitnessPal, Cronometer, Lose It!, Cal AI, SnapCalorie and Foodvisor all belong here.
• Ingredient scanners answer “is this product a good choice?” You scan the barcode on a packaged product in the shop and get a grade based on its nutrition profile, its additives or how processed it is. Yuka is the best known, and Open Food Facts and FoodSwitch work along similar lines. They grade products one at a time; they do not keep a diary or add up a day.

If you want to lose weight, build muscle, hit a protein target or keep carbs in check, you need the first kind. A product grade cannot tell you whether you ate 1,600 calories today or 2,600. That is why a nutrition scanner sits at the top of this ranking, and why the #1 pick is the app that scans both packaged food and the plated meals that have no barcode at all.

How we ranked these food scanner apps

We ranked the apps against six criteria that matter when you scan food, using each company’s published plans and feature lists. The order leans hardest on what a scan actually gives you:

1. What a scan returns. Calories, macros and nutrients saved to a diary rank above a one-off product grade, because they answer the question most people are asking.
2. Both scan types. An app that reads barcodes and photographs plates covers every meal of the day. An app with only one of the two leaves gaps you fill by typing.
3. The database behind the scanner. A scan is only as good as the entry it lands on. Verified entries give consistent numbers; crowd-sourced entries give you duplicates to choose between.
4. Control over the result. A good scanner asks when a photo is unclear and lets you correct ingredients and portions before you save.
5. What you can scan for free. A scanner that sits behind a subscription ranks lower than one you can use every day at no cost.
6. Price and reach. The cost of the paid tier, and whether the same account works on the web as well as on the phone.

Food scanner apps compared

Plans and prices come from each company’s pages and store listings, in US dollars.

Read across the free column and the difference is plain. PlateLens pairs unlimited barcode scanning with daily photo scans on a free plan that never runs out, and its Premium tier carries the lowest annual price in the table. On their free plans, MyFitnessPal includes neither scanner, and Cronometer includes the barcode scanner while keeping photo logging for Gold.

The best food scanner apps, ranked

1. PlateLens — best food scanner app overall

PlateLens is the scanner to install if the goal is knowing what you ate and how much of it. It reads food two ways and keeps both in the same diary, so a packaged snack and a home-cooked dinner are counted against the same database with the same rules.

• Photo scan for plates. Point the camera at a meal and PlateLens identifies the foods, estimates the portions and returns an itemized entry with calories, protein, carbs and fat, plus the nutrient detail behind them. When part of the photo is ambiguous, it asks you to confirm instead of guessing, and every ingredient and portion stays editable.
• Barcode scan for packages. Scan a product and PlateLens pulls it from more than 820,000 branded products with barcode data. Barcode scanning is unlimited on the free plan.
• The database behind both. 1.2M+ verified food entries and 45K+ restaurant menu items, so a scan lands on a checked entry rather than one of several user-submitted versions.
• What a scan adds up to. 82+ nutrients across vitamins, minerals, amino acids and fatty acids; total carbs, net carbs, fiber and sugar for every meal; water and weight alongside.
• More than a camera. Voice and typed logging for the coffee and the apple, an AI coach that answers with your diary as context, a recipe and meal planner with grocery lists, two-way Apple Health and Health Connect sync, and JSON export of your full history. The app runs in English and Spanish.
• Phone and browser. A full web app at platelens.app/web uses the same account and diary. You can upload a meal photo or log a barcode from a laptop, and see a month of meals at once.

Price. The free plan never expires and needs no card: unlimited barcode and typed logging, three AI photo scans a day, five coach messages a day and the web app. Premium costs $34.99 a year or $9.99 a month for unlimited photo scans and coach messages, the cheapest paid tier among the major trackers.

Best for: anyone who wants one app to scan everything they eat, packaged or plated, and get real numbers back.

2. Yuka — best for an ingredient grade on packaged food

Yuka answers a different question from every other app here: is this packaged product a good choice? Scan the barcode and it shows a color-coded score from 0 to 100. Yuka says nutritional quality makes up 60% of that score, additives 30% and organic status 10%. For low-scoring products it suggests similar items that score better, and it rates cosmetics as well as food. It is free, with an optional Premium upgrade, on iPhone and Android.

What Yuka does not do is count. It keeps no food diary, adds up no calories or protein, and works from product barcodes, so a plate of home cooking gives it nothing to scan. If your interest is ultra-processing specifically, the free Open Food Facts app shows a product’s NOVA processing group next to its Nutri-Score.

Best for: shoppers who want a quick verdict on a product in the aisle and have no calorie or macro target. If you do have a target, you need a nutrition scanner such as PlateLens.

3. MyFitnessPal — biggest crowd-sourced food database

MyFitnessPal is the name most people know, and its draw is size: the company cites more than 18 million foods in a database its members add to and edit, with wide restaurant and packaged-food coverage and 40+ connected apps and devices. As a scanner, though, it is a paid product. The barcode scanner, Meal Scan (its photo logging) and Voice Log are all Premium features, at $79.99 a year or $19.99 a month. A crowd-sourced database also means several entries for the same food, which you choose between yourself.

Best for: long-time users with years of history in the app who already pay for Premium.

4. Cronometer — best for micronutrient depth

Cronometer is the specialist for people who track vitamins and minerals as closely as calories. It leans on lab-analyzed food data, and its homepage cites up to 95 nutrients and compounds. The barcode scanner is part of its free plan, which carries ads. Photo logging, voice logging and the Crono Coach assistant are Gold features, at $59.99 a year, so on the free plan anything without a barcode is searched and typed.

Best for: micronutrient-focused trackers who are happy to search and weigh, or to pay for Gold to get the camera.

5. Lose It! — easiest start for beginners

Lose It! is built for people who have never tracked before: a clean, goal-led interface, barcode scanning on the free plan, and a photo feature called Snap It. Premium costs $39.99 a year.

Best for: first-time trackers who want a weight-loss goal and the simplest possible setup.

6. Cal AI — camera-first calorie counter

Cal AI is built around the camera: photograph a meal and it returns itemized calorie and macro estimates. Barcode scanning is supported too, and the photo flow is what the app is known for. Check the current plan on its store listing before subscribing.

Best for: people who want a photo-first app above everything else.

7. SnapCalorie — photo app focused on portion size

SnapCalorie is a photo-first calorie counter whose pitch is portion estimation, working out how much food is on the plate, which is the hardest part of logging from a picture. Its focus is calories and macros rather than a deep nutrient panel.

Best for: camera-only loggers who care mainly about calories and macros.

8. Foodvisor — photo logging with dietitian access

Foodvisor, based in Paris, pairs photo recognition with in-app access to dietitians, and it is available in English, French, German, Spanish and Italian. There is a free tier.

Best for: European users who want photo logging alongside guidance from a dietitian.

Photo scan or barcode scan: which one when?

Use the barcode whenever the food has one. A barcode scan pulls up that exact product, so the nutrition values match the package and the only thing left to set is how much you ate. Check the serving: if the label’s serving is 30 g and you poured 50 g, change it. For a longer look at barcode-first tracking, see this guide to barcode calorie trackers.

Use a photo for everything without a label. Home-cooked dinners, restaurant plates, a salad bowl from the café down the street. Typing these in means guessing at ingredients and amounts, which is exactly the part people find hardest. A photo scan identifies the foods and estimates the portions in one step. In PlateLens the app checks with you on anything ambiguous and lets you adjust each ingredient, so the entry ends up matching the plate in front of you. This step-by-step guide to scanning food for calories walks through the habit, and our explainer on food photo calorie apps covers how the recognition works.

Use voice or typing for the small stuff. A coffee with milk, the apple you ate in the car, a handful of nuts.

The value of an app that does all of these is that you never choose an app per meal. Every scan lands in one diary, and the day adds up in one place.

How to choose a food scanner app

Start from what you want to know, then match the app to it.

• Choose PlateLens if you want calories, macros and nutrients for everything you eat: barcode scans for packaged food, photo scans for plates, one diary on phone and web, a free plan that never expires and the cheapest Premium if you want unlimited photo scans. This is the right pick for most people, and the one to install if you only install one.
• Choose Yuka if you only want to grade packaged products while you shop and have no interest in counting anything.
• Choose MyFitnessPal if you already pay for Premium and rely on its crowd-sourced restaurant and packaged entries.
• Choose Cronometer if micronutrient detail is the reason you track, and you are fine typing your meals or paying for Gold to use the camera.
• Choose Lose It! if you are new to tracking and want the simplest possible start.
• Choose Cal AI or SnapCalorie if you only ever want to log with the camera; Foodvisor if you want dietitian access in a European language.

Two quick questions settle most decisions. Do you want a number for your day, or a verdict on a product? A number means a nutrition scanner. Do you eat both packaged food and plated meals? Almost everyone does, which is why an app that scans both, without charging for the barcode scanner, comes out on top.

How to get better results from any food scanner

1. Scan before you eat. A photo of a full plate shows what you served; a photo of leftovers does not.
2. Get the whole plate in frame, in good light. Every item the camera can see is an item it can name.
3. Confirm and correct. Answer the app’s questions about anything ambiguous and adjust a portion if you know it better, for example when you weighed the rice.
4. Check the serving on every barcode. The product is exact; the amount is up to you.
5. Save the meals you repeat. Your usual breakfast should take one tap, not a fresh scan.
6. Log close to the meal. Entries made hours later are the ones people forget. Our guide to AI or manual food logging covers how to make the habit stick.

Counting food does not suit everyone. If you have a medical condition, are pregnant or have had a difficult relationship with food, talk with a doctor or registered dietitian before you start tracking.

The verdict

PlateLens is the best food scanner app in 2026 and our pick going into 2027. It is the one app here that scans both ways that matter, a photo for the plate and a barcode for the package, and turns every scan into calories, macros and 82+ nutrients in a single diary. The numbers come from 1.2M+ verified foods and 820K+ branded products with barcode data, the app asks before it guesses, and every ingredient and portion can be edited. Barcode scanning is unlimited and free forever, three photo scans a day are included, the web app comes with the same account, and Premium at $34.99 a year is the cheapest paid tier among the major trackers.

Yuka remains the right tool if all you want is an ingredient and additive grade for packaged products. For everyone who wants to know what they ate and how much, start with PlateLens on the free plan. For a broader ranking of camera-based trackers, see the best AI food trackers.

Frequently Asked Questions

What is the best food scanner app?

PlateLens is the best food scanner app for most people. It scans a barcode for packaged food and a photo for a plated meal, and turns either scan into calories, macros and 82+ nutrients in one diary, backed by 1.2M+ verified foods and 820K+ branded products with barcode data. Barcode scanning is unlimited on a free plan that never expires, with three AI photo scans a day. If you only want a grade for a packaged product’s ingredients and additives, with no calorie count, Yuka is the specialist for that.

What’s the best app for tracking food?

For most people, PlateLens. It takes photo, barcode, voice and typed entries in a single diary, searches a verified database of 1.2M+ foods, tracks 82+ nutrients, and runs on iPhone, Android and the web on one account. The free plan never expires; Premium is $34.99 a year, the cheapest paid tier among the major trackers. Pick a specialist only for a specialist goal: Cronometer for micronutrient depth, MacroFactor for adaptive targets, MyFitnessPal for the biggest crowd-sourced database.

Is there a free food scanner app?

Yes. PlateLens includes unlimited barcode scanning and three AI photo scans a day on a free plan that never expires and needs no card, so one free app scans both packaged food and plated meals. Yuka is free to use, with an optional paid upgrade, for ingredient grades. Cronometer’s free plan (with ads) and Lose It!’s free plan also include barcode scanning, while MyFitnessPal keeps its barcode scanner and Meal Scan for Premium.

How does the Yuka app work?

You scan the barcode on a packaged product and Yuka gives it a color-coded score from 0 to 100. Yuka says nutritional quality makes up 60% of the score, additives 30% and organic status 10%, and for low-scoring products it suggests similar items that score better. It also rates cosmetics. Yuka is free with an optional Premium upgrade and runs on iPhone and Android. It does not keep a food diary or add up your calories.

Can an app count calories from a photo of my food?

Yes. A photo-based food scanner identifies the foods on the plate, estimates the portions and looks each item up in a nutrition database. In PlateLens, the result is an itemized entry with calories, macros and the full nutrient breakdown; the app asks you to confirm anything ambiguous in the photo, and every ingredient and portion can be edited before you save.

Should I scan the barcode or take a photo of my food?

Scan the barcode whenever the food has one, because it pulls up that exact product, and then set the amount you actually ate. Take a photo for food without a label: home-cooked dinners, restaurant plates, a bowl from a café. PlateLens does both in the same diary, so you can use whichever is quicker at each meal.

Can I use a food scanner app on my computer?

PlateLens has a full web app at platelens.app/web on the same account as the phone apps. On the web you can upload a meal photo, log a barcode, type or speak an entry, and open any meal to adjust its ingredients and portions. The web app is included on the free plan.

Which food scanner app has the cheapest premium plan?

PlateLens Premium costs $34.99 a year or $9.99 a month and unlocks unlimited AI photo scans and coach messages. That is below Lose It! Premium at $39.99 a year, Cronometer Gold at $59.99 a year and MyFitnessPal Premium at $79.99 a year.
