Fax machines are so 1996. But there are times when someone insists that you fax them a document—while you're on the road. In that situation, iFax Pro will spare you mucho aggravation. The app lets you snap a photo of a document (or anything else for that matter) and fax it directly from your iPhone or iPad. The app integrates with Dropbox, so you can add docs from your Dropbox folder to a fax. You pay $1 to send a fax with up to five pages; $2 for a fax with 10 pages, and so on. As for receiving faxes, you'll need to spend $13 per month or more for a local fax number.
