Really like the app because it does what it says it will do. It needs to be clearer on how to actually fax. I use onenote and I had to email myself the document and then go to my email and open it. Once I did that I then opened the PDF in Faxfile and then sent. The interface could be more straightforward. I wasnt sure if the add fax number was for the fax I was about to send or adding to my contact list. Overall though it saves me from having to mail stuff or wait to find a fax machine.
