How to set up the Anki app for iOS?

Question

English learning tools

I have an Anki app on my Android phone where I add new words and phrases.
I installed it a few years ago, but I remember that immediately after installation I checked somewhere in the settings or something so that instead of the usual cards it was possible to hide the correct answer (word) and a field for entering the answer appeared below. If I answer correctly, it is highlighted in green, if there are errors in the word, then it is highlighted in red.
My friend downloaded the free Anki app on her iPhone. But it cannot set up input fields instead of classic cards.
The question is how to set up this feature to work on an iOS phone?
