CalorieCount.com and CalorieKing.com both have free nutritional calculators that display both the caloric and carbohydrate count of many common foods. Individuals can use both sites for free online, though users are required to create accounts to track calorie and carbohydrate consumption and access additional features.
Calorie and carbohydrate counters work by providing users with the average nutritional information for common foods. Users can find foods by browsing libraries that sort foods by type, or by typing keywords into the search bars located on each page. Both sites also feature web-based counters as well as mobile apps that allow users to calculate and log foods they eat from their mobile devices.
