Does what it says

I like this app it does exactly what it says. I can add things to my DropBox and attach them flawlessly on my iOS device and fax them via wifi without a problem. When the fax is successful I receive a notification on my watch. While I think faxing should become extinct my mortgage company does not and faxing is the fastest way to get information to them. I gave it 4 stars because the pessimist in me thinks Im being gouged. Whenever I need to send a fax, the app always tells me Im just 10 credits shy of whatever amount is needed in order to send.
