Thanks. It's available only for the US layout, not UK.

I'm writing down a few impressions: - the layout is unusual, but I get the motivation. Distances are minimised and letters are arranged so that ambiguity is removed. - although I'm very slow, I haven't made a single mistake so far. Clearflow allows me to swipe much more accurately than stock gboard. - the square keyboard layout unfortunately means that half the letters are constantly hidden behind my thumb. As I'm unfamiliar with the layout, this means that before swiping a word, I have to look at the layout, memorise letter locations and plan the movement - since I write in multiple languages and Clearflow is available in only one of them, I would have to memorise a completely new layout for a language I write in only half the time.
