Definitely the best keyboard on the store bar none. Accuracy is better than the stock keyboard. This is a power user board that rewards practice and patience with lightning fast keyboarding and excellent accuracy.
The learning curve is significant, but not punishingly so. It is well worth the investment of time. Start out conservatively. Use taps and only gradually incorporate the sliding.
The board is supremely customizable, and allows the use of shortcut keys like no other. I have modified it to type an em-dash (―) simply by pressing and holding the M key.
One problem: the board learns new words quickly, which means that every time you make a mistake that mistake gets added as new vocabulary term which seems (although I have no evidence other than my own perception) to affect accuracy over the long term. This can be remedied by periodically cleaning up the keyboard dictionary and removing these junk words.
Lastly, the developer has implemented several brilliant features that really make it easy to go back over your text and correct any errors. Tap the word and then slide up or down to select the correct word. No other onscreen keyboard offers this kind of power and youll quickly become dependant on these time saving features.
