A few days ago, we wrote about a handy app called CamScanner, which scans any photo and turns it into a digital document. It does get the job done, but what if someone sends you a digital document that you need to sign? You know, like your manager, agent or the head of your trust fund?

No worries! There’s an app for that, too. SignNow is a web and mobile app that allows you to use your fingers to sign a PDF, Word or text file within your touch-enabled device.

Available for both Android and iOS, this free app lets you upload a file either from email or Dropbox and lets you sign on documents like contracts, permission slips, sales agreements and other things that need your signature. The signature is rendered into the document with precision, and if you’re careful, it can even look like an actual signature on paper.

You can then save the document on your phone, then send it through email or upload it to SignNow’s servers when you register for a free account.

Pretty nifty, right? Now you can save the time you spend printing out a document and looking for a pen — if there’s any at all lying around.
