Can't get apps onto iphone 5?

I download the apps from the App Store and they download into the launchpad section of my macbook pro, but not the "Apps" section of my iphone in iTunes, so i can't get them onto my iphone.
Suggestions?

Uh, you are downloading apps for the Mac when you use that App Store. The App Store to get apps for the iPhone is in iTunes or on the iPhone itself. That is the one you need to use.

What you are downloading from is the Mac App Store, which is only apps made for your mac, and not your iPhone. The apps for the Mac is not compatible for the iPhone, however, the publisher may have also created an app just for the iPhone. If you want to search for apps for your iPhone, there are two ways. Open iTunes, and in the top right, type the app (You can just more than apps, such as typing the name of a song for example.) and then download it. Plug in your iPhone and sync it, the app should appear on your iPhone. The easier way is to simply go into the App Store on your iPhone and look for the app that way.
