Then it was killed, and Android shipped its default keyboard ("gboard") with one that included swiping. I've used it ever since, not thinking about it, but it has never been as good as Swype, and about 20% of my words are errors. I don't think about it much because their autocorrect suggestions are pretty good when you tap on a word, but it really is annoying. Honestly, it's insane that I keep swiping because it would be faster just to type than to swipe and correct every fifth word.

I have now downloaded Swiftkey. We'll see if it's any better. My first gripe is that the backspace key doesn't delete a whole word, which, when you're swiping, seems natural to me (either the whole word is right or it's not), but I'm sure there are settings and improvements I can make as I get used to it.

(Edit: The translate as you type feature is a perhaps-niche but killer feature for me. I often have to write to people in my poor Spanish, and always had to go back and forth between the Translate app and the app I was writing it. Doing it as I type is amazing.)
