Cheapfax

Cheapfax is an iPhone app that allows users to send outbound faxes to the US and Canada without monthly subscription fees. Users can scan documents using their camera, import files, or share PDFs directly from other apps, paying a flat rate of 50¢ per page via Apple In-App Purchase.

Built with privacy in mind, credit purchased through the app never expires and documents are deleted 30 days after sending. If a transmission fails, the page cost is automatically refunded to the user's account balance.
