Someone made what looks like an actually good chording keyboard for Android.
Qwerty is an actually good layout for mobile, but it’s still a traditional keyboard layout, so it still sucks ass. A chording keyboard, where you don’t really need to move your fingers, gets the advantages of bigger keys and less room for error.
Or, well, after you actually learn to use it properly that is. Steep learning curve and all that. I don’t even type that much on mobile, but I might still want to take the effort if I find something that has sticking potential.
