Superhuman is an email client that lets you interact with Gmail without having to be in the Gmail web UI or the Gmail app on your phone. Superhuman prides itself on speed, letting you get around and work with your email really quickly. They were one of the first apps to have command K supportcommand. If you hit command K, it brings up a action bar. You can also do remind me on desktop, which is one of the killer features. This is huge for anyone who's got a commute.
