I can't download an app

[boatschool97]

I am unable to download an app from the app store, even though my settings is saying I have 184 MB Available and only 27.7GB used.  How do I purchase the app?

Which app is it? What happens when you try purchase it or download it?

IN order to download to your iPhone, you need at least twice the space that the app requires.  So if the app is 100 mbs, you need AT LEAST 200 mbs free.
