App will not work unless you give it access to everything on your phone. It pretends to offer you a choice, but if you don't allow it then it gives an error saying it can't procede until you give it access. On the plus side the find my ear bud feature works well, it was loud enough to hear from an adjoining room when there was no ambient noise. And it is a small enough download to install when needed and then promptly uninstall.
