You're right. The Ink Mobile Framework is trying to solve the app to app communication problem on ios where apps don't work together.[1]

Because it's the pipes between apps, in order to demonstrate it, you need the source applications. Therefore, the suite of 4 apps that work well together. You'll find that most of the apps are barebones, but with ink connecting them together, you're able to do things that you can't currently do (e.g. Get an email attachment, edit the photo, save a copy to your dropbox, and then send it back as a reply.)

We have a number of partners lined up: Evernote, SignEasy, Podio, et al and we're super excited to see them go live.
