While it may not be best-in-class at other things, there's no debating that BlackBerry has a superior keyboard, even to Apple's. Octopus Keyboard brings that easy-to-use BlackBerry 10 keyboard to your iPhone, with a QWERTY layout that uses predictive text to suggest words that the keyboard thinks you're in the process of typing. You merely have to swipe up to select the word that you want.
