Is this how most people type on mobile these days, drawing lines all over a keyboard instead of tapping the individual keys? I’ve never had an iPhone so I don’t even know if they can do this natively, but I know you can switch keyboards at least, so it should still be an option if not.
Same, but even when I type one-handed, I also bounce back and forth at each word. Swiping gets short words wrong more often, but more rarely long words.
So for instance, for “I am on vacation”, the only word I’d swipe when one-handed is “vacation”. If I swiped “am”, I’d probably have a 50-50 chance of getting “an”; which may or may not self-correct later, depending on what else it got wrong.
