Penny, there are a few depending on the operating system you use. A lot of people like MyFitnessPal. I tried it and it worked fine but it did more than I needed it to. I settled on using FatSecret.
My suggestion is to go to your device‘s App Store and look at a few. Many will let you try them for free and you can see how you get along.
