There is some speculation that the incredibly addictive and obsessive Ingress app for Android, designed by Google years ago, is coming to iOS.
Brandon Badger from Google, the Niantic Labs at Google, who came up with the Ingress game said in a Google+ post that he is working on a secret project.
He posted a picture of a new iPhone 5 and wrote, "This thing sucks compared to my Android phone, but I need to play around with it for a secret project."
So of course, the assumption is, he is bringing Ingress to iOS, which would be nice.
