This app is terrible, don't use it! – FAX from iPhone & iPad App Review

Of course after you purchase the app and get all set up and ready to send your document, guess what? It requires you to buy credits! They should be up front about the cost to use this app and at least be transparent up front, instead of being sleazy about the upsell. I might as well drive down the street to FedEx Office!
