Adobe has brought EchoSign over to Android, so now workers can use the mobile app to close deals with clients, job applicants can use it to sign contracts, and just about anyone can use it to put their John Hancock on any of the myriad of documents that require a signature. The app lets people e-sign documents using either their fingers or a stylus and/or request signatures from others. Even better, it happens to integrate with a number of cloud storage providers (Google Drive and Box make the list, but Dropbox, oddly, isn't mentioned).
My name is Ivo, and recently I posted this write-up on Reddit (check out the Android subreddit while you’re there!). The post gained quite a bit of traction, and to spread the word further, I'm now posting it here at Android Police. I hope it helps out those of you who are confused.
