Inbox is not a Gmail replacement, but rather a trial balloon from Google that offers a refreshingly unique, novel way to navigate one of the oldest digital tools — the inbox. Last month Google moved its Inbox email service from private beta to open beta, meaning anyone who wants to try out the service is welcome to give it a try.
The Gmail Inbox is an invite-only system that works on the Chrome browser, Android phones, and iPhones. It feels completely native and fast on all of those systems. But it’s a native and fast app that does something 10 degrees away from what you’d expect an email app to do.
