No app

Your iPhone is already good at conserving space anyway and 64GB should be plenty of space. Apple actually prohibits apps like the one that you want from entering the App Store.

This app should do the trick for you. It's easy to use and works well with voiceover. Let me know if you have any issues. Happy cleaning! :-) Memory & Disk Scanner Pro - Check System Information by Phan Minh Nhut

Manage Storage

Look in settings, general, Storage & iCloud Usage.
I found a lot of data used by some of my apps. It does seem that you can only delete the app to remove its data. For example one of my apps shows: App Size: 87.5 MB
AndDocuments & Data 15.2 GB
I do not see a breakdown of what that data is. And there is only a delete button for that app.

i do wish we could...

I have a 128gb iPhone with 97MB free. I wish we could clean up the temp files and stuff, because then I'd have about 2gb or so free.
