The Verge has been testing the new app for a few weeks and is impressed.
Whereas most Mail apps rely on buttons to archive, delete, and file emails for later, Mailbox relies on a simple and colorful set of swipes. "Email was designed 30 years ago for computers chained to desks," [Orchestra CEO Gentry] Underwood says. "Everything about it is slow and clunky. If you want to make it fast and mobile-friendly, the entire experience needs to be modernized." Swiping a message to the right archives it (symbolized by a checkmark), while swiping a message to the left saves it for later (a yellow clock symbol). Swiping a message to the right and holding deletes it (symbolized by a red x), and swiping a message to the left and holding opens a List screen where you can move / label messages. In grand total, there are four ways to act on a message in your inbox, which means there’s a bit of a learning curve, but it’s worth it.
The app is coming out in the New Year. More details can be found in their review or check out the video below...
