Google Keyboard - Android Apps on Google Play.
The new upgrade to many Google apps included the standardization of the various Android keyboards into a swiping style keyboard just called Google keyboard. It is smart, and just gliding around from letter to letter will produce very accurate and fast results. If you are used to hunt and peck one letter at a time, it will take some getting used to. But, once you get the hang of it, you will never go back. I must admit, however, that I am using voice to dictate more and more, as the Google voice engine keeps getting better. I am waiting patiently for the day when Google Now can read my mind, and I can give it commands and dictation with my thoughts.
