Very good app, it takes a minute for the server to send a fax, but it works!, specially since you dont have to subscribe to a fax service and or pay for every time you have to send a fax or buy expensive almost extinct out of date equipment and paying for an extra phone line just to send a fax. with the exception of some missing characters used in language like Spanish (the tilde or the diacritical tilde over the n) that are missing on the receiving page, also pictures dont come out so clear, but that can be fixed by changing colored pictures to monochromatic tones (make them black and white), also the receiving cover letter page has a bit of propaganda that can be a bit too much. I can tell you I was a bit nervous when I read other reviews warning that the app doesnt work, but with a bit of patience all will be ok!
