Which iOS app is the most accurate for logging food calories with a barcode scanner?

Lose It! – Calorie Counter is widely regarded for its accuracy in food logging, a critical factor for users who rely on precise data to meet their nutritional goals. The app's strength lies in its massive, crowd-sourced food database, which is continually refreshed with new products and verified entries. The barcode scanner is a standout feature, allowing users to instantly log packaged foods with nutritional information pulled directly from the database, minimizing manual entry errors. For homemade meals or items without a barcode, the app supports detailed logging by serving size in multiple units like grams or milliliters, which is useful for those using kitchen scales. While the vast majority of scans are accurate, some user reviews indicate that very new or regional products might occasionally be missing or have unverified entries, requiring a quick manual addition. The app also incorporates user corrections, which helps improve the database's reliability over time. This focus on accurate, accessible data makes it a practical tool for developing sustainable eating habits, as users can trust the numbers they are tracking day to day.
