This app’s handy barcode scanner zaps the label of an item you’ve eaten and records the calories to help you stay within your daily calorie limit. But there are lots of iPhone apps that count calories. The real benefit of FatSecret’s app is its massive nutritional database, including many popular food brands, chain restaurant meals and grocery-store items. You’ll rarely have to search for and separately list each ingredient in a restaurant sandwich again. With Calorie Counter, you’ll often find the whole sandwich already in the system. Equipped with a food diary and an exercise log, FatSecret’s app also helps you track calories consumed against calories burned.
