Yes, you can find your lost iPhone with an iPhone app. However, you must have access to another apple product with the same app to locate your lost iPhone. It's called FindmyiPhone in the app store, and it's free. All you do is make an account. Let's say your iPhone is lost, all you do is sign in with your account with another device with the same app and the app will do the rest. Its quite amazing.
