In a nutshell, pressing the button this extension adds to Anki either pastes the contents of your clipboard as syntax-highlighted code, or applies syntax-highlighting to the text you have selected.
This makes code much, much easier to parse, especially when using Anki on a mobile device.
I'm guessing that's not going to do much in the Anki iOS app though.
On the plus side, checking the app to see if such an option exists found a bunch of options I didn't know about that will make my experience more pleasant. Ta.
