Still, it's an interesting concept. You can even use Gmail Tap on iOS. Announced on the Gmail Blog, Gmail Tap means that users can dot-and-dash their way to typing using Morse code.

"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."
On the product page, Google promises some other features:
- Multi-email mode so you can type two emails at once
- Ship to shore mode, using your phone's flash (coming soon)
- Table tap, which uses your phone's microphone to pick up the sound of off screen tapping (coming soon)
