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.
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.
評価点：People say the app literally changed their shopping habits: they now read labels and choose cleaner products.
不満点：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.
向いている人：People who want to quickly check a product's ingredient list in the store
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.
評価点：Works for free without a subscription and quickly shows the points value of any product.
不満点：There is no way to keep a daily log: the app is only a points reference, not a tracker.
向いている人：Weight Watchers followers who do not want to pay for the official app
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.
評価点：A free database with millions of products and a clear food diary without unnecessary features.
不満点：After recent updates the food search broke: even 'Twix' does not come up.
向いている人：Home cooks and long-term nutrition trackers who do not want to overpay
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.
評価点：Six years of loyal users stay for the micronutrient tracking alone. No other free app comes close.
不満点：After the latest update, search ranks branded products above basics, so finding 'banana' now takes several screens of scrolling.
向いている人：People who track vitamins and minerals, not just calories
