What to check before choosing

The reviews ask how the final verdict on a product was arrived at. It is more useful to open up the composition and the grounds for the rating than to hand out a single unconditional label.

Which apps people use

These apps are mentioned in the breakdown of this job. Open each one to compare strengths and limits. The order of the list is not a ranking of fitness.

  1. Yuka - Food & Cosmetic Scanner

    Rank 6. Review score: 68 out of 100. App Store rating: 4.8★ · 95,245 ratings

    A barcode scanner for food and cosmetic ingredients that quickly shows a rating and explains problematic ingredients. The main flaw is an open database with insufficient moderation, leading to errors, while identical products can receive incomparable scores due to a shallow algorithm.

    Praised: People say the app literally changed their shopping habits: they now read labels and choose cleaner products.

    Complaints: The scoring algorithm does not account for dosage and evaluates individual ingredients rather than the full formula, so similar products get different scores without a logical explanation.

    Best for: People who want to quickly check a product's ingredient list in the store

  2. Smart - Food Score Calculator

    Rank 22. Review score: 62 out of 100. App Store rating: 4.6★ · 2,384 ratings

    The app calculates Weight Watchers points without monthly payments, and for its purpose it delivers honestly. The barcode scanner is broken for many users, and the restaurant database has not been updated in a long time.

    Praised: Works for free without a subscription and quickly shows the points value of any product.

    Complaints: There is no way to keep a daily log: the app is only a points reference, not a tracker.

    Best for: Weight Watchers followers who do not want to pay for the official app

  3. Calorie Counter by fatsecret

    Rank 12. Review score: 66 out of 100. App Store rating: 4.8★ · 14,326 ratings

    A reliable free veteran with a huge food database and honest macro tracking. Search degraded after recent updates, and water tracking behind a paywall irritates long-time users.

    Praised: A free database with millions of products and a clear food diary without unnecessary features.

    Complaints: After recent updates the food search broke: even 'Twix' does not come up.

    Best for: Home cooks and long-term nutrition trackers who do not want to overpay

  4. Cronometer: Calorie Counter

    Rank 1. Review score: 74 out of 100. App Store rating: 4.8★ · 93,490 ratings

    The most thorough free micronutrient tracker in the category: the only one that shows vitamins, minerals, and a full nutritional profile at no cost. A recent update degraded search results by pushing branded items ahead of generics, which seriously slows down daily logging.

    Praised: Six years of loyal users stay for the micronutrient tracking alone. No other free app comes close.

    Complaints: After the latest update, search ranks branded products above basics, so finding 'banana' now takes several screens of scrolling.

    Best for: People who track vitamins and minerals, not just calories
