The QWERTY keyboard was invented in 1874 and yet it is still used today, largely unchanged. Today we’re excited to introduce a new input method designed for the future: Gmail Tap for Android and iOS. Watch the video for an overview:
Gmail Tap takes the keyboard from 26 keys to just two. Every letter of the alphabet is represented by a simple pattern of dots and dashes, and once you know them you can type without even looking at your screen. This makes it ideal for situations where you need to discreetly send emails, such as when you’re on a date or in a meeting with your boss.
