The top rated Keyboard for Android
Phone is SwiftKey.
You can search on Google about efficiency statistics which you also can share after using the keyboard as it keeps track of all corrections , flow etc.
It makes your writing speed 4x times faster. It also predicts the next word if you are not good in grammar.
I have wrote this article by using SwiftKey keyboard. And i haven’t wrote anything completely by myself. SwiftKey helped me in writing each and every word.
I give this app FIVE STARS-
By comparing it with Swype keyboard, Sine keyboard i gave the rating.
You will get auto templates in other keyboard and other Emojis.
But your writing won’t be much efficient by using other Android Keyboards.
