Not all features offered work

I was looking forward to using this app on PDF files. But it seems the share feature for this app is not functional. I dont see Speaky listed under that option when I want to share a PDF email attachment. I even tried copying the PDF to my Box account since this app help indicates it will work with Box. But still no option to add the PDF to my read list. Very disappointing.
