Works well for me. You just type with one hand without ever lifting your thumb. You do need to set the correct language, and if you mix languages, your phone's OS has to be able to deal with that, but at least on iOS that is the case and the prediction is very good. If the first choice isn't correct, usually the first or second displayed alternative is what I wanted.

There are two caveats, though. Firstly, I type differently when using swipe. As it favors words from the dictionary, my texts sound less spoken and more written. And secondly, having backspace delete the whole word is a critical feature to avoiding annoyance. If none of the predictions are correct, I just tap backspace and then type the word like I usually would. This, combined with the rarity of those hiccups makes swipe typing quicker than regular typing to me.

It also helps with relaxing my wrists as I can also hold the phone with one hand and swipe with the middle finger of my other in a gesture like holding a pen, but without the pen.

Maybe there's actually a third aspect; screen and hand size. I haven't owned any big phones, my iphone 13 mini is the biggest phone I ever owned, but I do have large hands, so swipe typing with a single thumb is not very difficult. Your experience might be different depending on your anatomy and device.

I've been using swipe for years now on my Android phones (currently a pixel 5). I hold the phone in one hand and use the thumb of the same hand to swipe. Feels much more effortless than "actual" typing. Especially when comparing it to typing with both thumbs.

It's indispensable for me. Works nearly flawlessly, and in English and Spanish at the same time, without having to tell the keyboard to change languages. I'm magnitudes faster with it, and rarely have to go back and correct anything.

This whole comment was written with swipe and didn’t require any corrections, I do much better with swipe than trying to tap all the letters. It’s pretty fast too.

Try downloading Gboard. Been using it for years. Dramatically better than iOS built in, which makes horrible decisions about when and how text is corrected and has worse gesture recognition.

After a relatively short time, I stopped having to look at the keys or think about letters. Touch typing from keyboard transfers over well.

Swipe is good on keyboards other than the stock iOS keyboard. That one is worse than every other option imaginable and it sucks to see because iOS used to have the best mobile keyboard bar none back before they tried to get smart with it.

I don't get along with it either -- it's the worst possible option for me. But I know a lot of people who get along very well with it. Different people are different.

Which phone do you have? I think it works great on the Mini, but I believe I recall it being a disappointment on a Max

I swipe with my index finder, holding the phone with my other hand, and I find that fairly efficient.
