Counting calories? This app borrows designs from financial apps to give you a budgetlike view that makes it easy to see what you’ve eaten and how much more will work for your daily allotment. After you set a goal of losing so many pounds per week, you input your age and weight to calculate how many calories you should eat per day. Then, you can input what you eat and how much you exercise to keep it all in check. The app has the calorie count for some foods on file, but you can also add your own foods for a more accurate count. Free, for iOS and Android devices.
