I think autocorrect is overrated and actually makes the typing process much more annoying. Also I’m not sure if 55wpm is supposed to be fast or not? I just did a typing test (monkeytype.com) on my iPhone and got 80 wpm with 0 mistakes, and I don’t use autocorrect.
Just tried and got 72wpm with 97% accuracy without looking… though honestly I think not looking is a bit pointless, since the keyboard is so close to the text anyway. It’s not nearly as jarring as looking at your keyboard when typing on a desktop.
