An iPhone keyboard with the Colemak layout that looks and feels like the iPhone keyboard, so the layout you type on your computer works on your phone too.
Why doesn't it ask for Full Access?
It doesn't need it. Without Full Access, iOS keeps the keyboard offline and apart from other apps, so nothing you type can leave your iPhone.
Is there autocorrect or a suggestion bar?
Not yet. The first version focuses on the layout and the feel of the keys.
Where are the dictation and emoji keys?
iOS doesn't allow third-party keyboards to use them. Switch to the iPhone keyboard with the globe key when you need them.
Some apps show the iPhone keyboard instead.
iOS uses its own keyboard for password fields and phone number pads, and some apps don't allow third-party keyboards. That's an iOS rule, not a bug.
