I personally use the swiping keyboard on ios and it seems to detect the wrong word with an almost malicious frequency. It also randomly Capitalizes things.
It's intriguing. Danny! Infuriating.
I think it's slightly worded if you swore. No. Slightly worded. No. Slightly worse if you swipe left handed. Yes. At last.
I also use it all the time and I hate it very much. It almost never works right on the first try.
For some reason, the one word that it just will not let me swipe is “and”. Which is, you know, somewhat common. I get all kinds of random things instead.
