Terrible on predictive text – Thingthing Keyboard: Connected, Unified, Private. Review

I don't get the hype with this keyboard. Sure you can attach files from Dropbox or use the calendar from the keyboard but I can already do that and I don't need those features over auto-correct that creates new words rather than suggesting correct spelling when one letter is off. It's so bad I can't even use it anymore. At least in the version I have, there's not even a visible line for choices of spelling / new word creation - and no return button! It's utterly useless. I kept it for months thinking sometime in my copious writing activities that it would reveal its relevance. But today I had it after complete and utter nonsense (I mean artificial intelligence has evolved to understand human grammar and speech so how is it that a supposedly time-saving "smart" keyboard can actually change written speech into grammatically hopeless nonsensical fragments of non-words? I hate this keyboard.
