We tried this app and haven't touched a printer or scanner since

And neither is easy to use when you're in a rush. So we, the StackCommerce deals team, tested an app that claims to do it all--scanning, signing, saving, and even faxing documents--right from your phone. After one week, we forgot any other methods existed. The SwiftScan document scanner and PDF editor app swept us off our feet. Plus, this weekend only, you can save an extra 18 on a lifetime subscription to the iOS and Android apps with code TAKE30 at checkout, dropping the price from 59.99 to 41.99.
