Browse iOS files on Mac?

Hello, for a while I have been trying to do the question above. It hasn't worked in any way so far, and I really don't feel like paying money for any software. I was wondering if I could get some information on this, such as how would I get the file directory in Finder on a MacBook Pro, or how to mount it as a disk, etc.. I need some files that are inside of my iPad that I can't access through iTunes or anything of the sort. There are paid services, such as iExplorer, but I genuinely hate that software. There are others, but they just don't seem to work with Finder. I would like to know if there is any free software to put the file directory of my iPad and iPhone in Finder, or if I even need software at all. If this isn't clear, here's an example.

I want to get some app files off of my iPhone. I want to use free or built-in software that works in Finder, so I can see timestamps and open it in apps and such.

How would I do this? Do I have to jailbreak my device? Do I have to pay for third-party software to do this? Someone please answer, I need this fast.

Thanks.

If it helps, I am on the latest verison of Mac OSX, 10.11.1 and my devices are all the latest versions of iOS for my iPod 5, iPhone 4s, iPhone 5, and iPad Mini.
