Just a UI? Maybe.

But every application has a specific action. See data is just well, data. What you do with it defines your application. Take something non-intrusive for a change, say the books a bookstore sells most. There's a wealth of information there. We could predict locally trending topics or the most common problems students face. But you could also predict what kind of audience the bookstore receives. It may not sound that creepy unless you find that the store gets a lot of depression related sales. That could get creepy very fast.

> The only solution to this is awareness on the users part and nothing else.

Awareness is extremely important even vital. But that is not it. Thousands of Girls Around Me apps probably exist and it is fairly possible though tough to find them. All I am saying is that efforts should be made in that regard as well.
