The iPhone has native OCR in iOS 15. You just use the regular camera and when you point it at text, a yellow button appears in the lower right of the screen and yellow brackets show the borders of the text area, press the button, and it takes a photo and converts the text, allowing you to copy it to the clipboard. I’ve been pasting it into an email, which may be where all the hard returns are generated. There are dedicated apps for OCR but I thought I’d try the free/built-in one before adding a separate app.
