How to report a inappropriate app found in the App Store on a iPhone?

I was on the App Store the other day and I found a app that I thought was inteeating enough to try out. Turns out the app was not very good at all. It was poorly managed (neglected almost) and there were several underage kids on the app and there was inappropriate content on the app that should not be shown to kids under a ceartain age. I am very concerned about more children being exposed to the app and I would like to know if there is any way I could report the app itself to apple or someone who will look into it.

Thank You
