I chose to download an application called Gethuman. The application was to download and install. According to the application store the application was installed. When I search for Gethuman on the iPad there are mo results. Where would have this application disappeared?

Try a hard reset and see if it pops up.
Hold the power button and the home button down at the same time until you see the Apple logo.
Let it reboot.
Also make sure you have paged your home screen all the way to the last page as it may have installed on a new page if the current one was full.
