Best Calorie Tracker Apps With a Free Barcode Scanner for iPhone in 2026

Best free barcode scanner calorie apps at a glance

What "free barcode scanner" actually means

Free can mean permanently unlimited, included with a free account, available only for one-off lookups, or temporarily unlocked while an app changes its pricing. That distinction matters more than a generic "free download" label.

• Explicitly unlimited in the free app: Cronometer says its Basic account includes unlimited barcode-scanner use.
• Included in the free tier without a stated cap: Foodnoms, MyNetDiary, FitBee, FatSecret, and Nutritionix Track include scanning in current free/core descriptions, but not every publisher promises a numeric lifetime allowance.
• Free browser lookup, limited app trial: ProTrack's browser barcode scanner is free with no account or scan limit; the iPhone app has a limited free allowance before an upgrade.
• Paid or changing: MyFitnessPal puts the scanner in Premium and Premium+. Lose It! says barcode and nutrition-label scanning are Premium features.

A barcode only identifies a record in an app's database. It does not independently verify nutrition. A study of 100 packaged foods across seven nutrition apps found large variation in product identification and label accuracy, which is why you should check the product, flavor, serving unit, and current label before saving an unfamiliar result. Read the peer-reviewed study.

1. ProTrack AI: best for privacy, offline use, and lifetime value

Free barcode status: unlimited browser scanner; limited free use in the iPhone app
Best for: private iPhone tracking beyond packaged foods
Account required: no
Offline: diary, goals, manual logging, history, and on-device photo scanning; new barcode lookups need internet

ProTrack AI is the best fit when a barcode scanner is only one part of your routine. Its App Store listing describes on-device AI meal analysis, no required account, barcode lookup, manual logging, and calorie and macro tracking. That gives users a path for homemade meals, restaurant dishes, and unlabeled snacks as well as packaged food.

Its privacy model is the key difference: meal photos are processed on the iPhone, the food diary stays on the device, and core tracking remains useful without an internet connection. Barcode lookup uses Open Food Facts and needs a connection for a new product. Use a manual entry or edit the serving when a regional or new product is missing.

Trade-offs: ProTrack currently requires iOS 26 or later, has no listed Apple Watch app, and does not promise permanently unlimited free scans inside the iPhone app. It is a poor fit if your top priority is an unlimited free app scanner or the largest packaged-food database.

2. Cronometer: best unlimited free in-app barcode scanner

Free barcode status: explicitly unlimited in Basic
Best for: permanent free scanning and detailed micronutrients
Account required: yes
Apple Watch: yes

Cronometer is the cleanest answer when you want a scanner that is both in the app and explicitly unlimited for free. Its free-tier page says Basic includes unlimited barcode scanning and can be used indefinitely. The App Store listing describes a curated database of more than 1.1 million verified foods and tracking for calories, macros, and more than 95 nutrients and compounds. The trade-offs are an account and ads in Basic.

3. Foodnoms: best free no-account scanner for Apple users

Free barcode status: included free; no public numeric cap found
Best for: Apple users who want no account, no ads, and a local-first experience
Apple Watch: yes

Foodnoms is a strong MyFitnessPal barcode scanner alternative. Its free-plan description includes barcode scanning, food logging, calories, macros, recipes, and no ads without mandatory sign-up. Its barcode help also documents a correction flow and Nutrition Facts label scanning for unknown products.

4. MyNetDiary: best free scanner with a staff-verified database

Free barcode status: included free; no public numeric cap found
Best for: verified packaged-food records and no-ad tracking
Account required: no
Apple Watch: yes

MyNetDiary combines a free barcode scanner with a traditional database-first tracker. Its App Store listing promotes no ads, no required account, macro tracking, and a staff-verified database of more than two million foods. The company says correction photos submitted through PhotoFoods are reviewed, while users can also create private custom foods. That correction workflow is useful, but submitted package and label photos leave the device.

5. FitBee: best modern ad-free scanner with another lifetime option

Free barcode status: described as "always free"
Best for: an ad-free modern interface and nutrition-label scanning
Account required: yes
Apple Watch: yes

FitBee's App Store listing says barcode scanning is always free, contains no ads, and supports nutrition-label scanning when a product is not in the database. It also has a $149.99 lifetime purchase, far higher than ProTrack's $39.99 lifetime unlock. FitBee's privacy policy says photos and natural-language descriptions sent through AI features are relayed to OpenAI for analysis, which differs from on-device meal-photo processing.

6. FatSecret: best established multilingual free option

Free barcode status: included in the free app
Best for: a conventional tracker with broad language support
Apple Watch: yes

FatSecret's current App Store listing includes barcode scanning, a food diary, macro reporting, exercise logging, weight tracking, photo recognition, and Health app integration. Its free-tier advertising and correction workflow are less clearly documented than Foodnoms or MyNetDiary, so treat it as a conventional account-backed tracker rather than a private local-first alternative.

7. Nutritionix Track: best for US, Canadian, and restaurant coverage

Free barcode status: included in the core app
Best for: North American grocery and restaurant data

Nutritionix Track's current App Store listing describes instant barcode scanning, more than 800,000 foods, claimed coverage of 95% of grocery items in the US and Canada, and menus from more than 760 restaurant chains. Those figures are developer claims, not an independent audit. Its main website currently says it is being upgraded, so the App Store listing is the clearest public product source at the time of review.

8. MyFitnessPal: a large database, but not a free-scanner option

MyFitnessPal still has a large food database, extensive integrations, and a familiar workflow. But its official feature comparison puts Barcode Scanner in Premium and Premium+. Its public pricing page currently lists Premium at $79.99 per year and Premium+ at $99.99 per year, subject to country and offer differences. If the barcode paywall is why you are switching, read our MyFitnessPal price increase and paywall guide.

9. Lose It!: scanner access is not reliably free

Lose It! remains a mature weight-loss tracker with a large database, but it is not a dependable free-barcode-scanner recommendation. Its App Store listing places barcode scanning, photo meal logging, and AI voice logging in Premium. Existing free accounts may see different behavior during the transition, but new users should assume scanner access requires Premium. For the ownership comparison, see the best calorie tracker apps with lifetime access.

Feature and pricing comparison

Prices are current US App Store or official US prices checked August 17, 2026. They can vary by storefront, promotion, account, and legacy subscription status. Database-size figures are developer-reported and not directly comparable audits.

How to choose a barcode calorie app

1. Decide whether permanently free scanning is essential. Choose Cronometer if it is.
2. Check your real grocery routine. Scan several recurring products and compare results with the package label.
3. Check the correction path. A good tracker lets you change a serving, edit a wrong result, or make a private custom entry.
4. Separate privacy from price. A lifetime purchase does not automatically mean local processing.
5. Test a meal without a barcode. Most food is homemade, restaurant-prepared, or unlabelled.

If your main reason for switching is privacy rather than price, the private and offline calorie tracker comparison goes deeper into local storage, account requirements, and cloud photo processing.

Final recommendation

Cronometer is the best choice for a permanently unlimited free in-app barcode scanner. Foodnoms is the strongest no-account Apple-native free option. MyNetDiary is compelling for a verified packaged-food database.

ProTrack AI is the best overall choice for a privacy-conscious iPhone user who wants more than a barcode scanner. It gives you a no-account, local-first diary, on-device meal-photo analysis, manual and barcode logging, editable results, offline access to core tracking, a free unlimited browser scanner, and a lower-cost lifetime option. The limitation is clear: unlimited scans inside the iPhone app are paid, so choose Cronometer instead if permanently free in-app scanning is non-negotiable.
