Created by Orchestra, the company behind the popular to-do list app of the same name, Mailbox eschews most of the regular functions of an email client and replaces them with new swipe gestures. Swiping a message in your inbox to the right archives it; swiping to your left saves it for later, which means it schedules it to pop up back in your inbox at a later more opportune time; swiping to the right and holding it deletes the message, and swiping to the left and holding it brings up a menu where you move or relabel the message.
