C for Calories lets users log meals with a photo, a barcode, a food search, or a quick manual entry. Its image recognition estimates foods and portions, then shows calories and protein, carbohydrate, and fat totals that can be edited before saving. The app also supports daily calorie and macro targets, charts, a food diary, widgets, and a one-tap way to log a frequent meal again. The developer says the tracking tools, including unlimited scans, are free, with optional paid plans to remove advertisements. The diary does not require an account and stays on the iPhone according to the listing. Nutrition values from image recognition are estimates, and the developer says this is not a medical device or source of medical advice. Apple reports that identifiers and usage information may be used for advertising and analytics.
