MyNetDiary can import recipes from other iOS apps, if the app provides "share" functionality.
The following instructions and screenshots are for iOS 13 and later. On older versions of iOS the steps are slightly different in details.
In Safari web browser or in another recipe app (such as Paprika or AllRecipes), open the recipe you want to import and tap the Share button. In some apps, Share could be a menu option or it could be named differently, for example "Share Link."
If a recipe app does not support sharing, then importing a recipe from this app is not possible technically. As of June 2020, AnyList app does not support recipe sharing.
Then, scroll to the bottom of the share sheet. You should see MyNetDiary Recipe Import action (if you don't see it, you need to enable it following the instructions below.) Tap MyNetDiary Recipe Import while viewing a recipe in the web browser or a recipe app. This should launch MyNetDiary app and start the import process.
If you don't see MyNetDiary Recipe Import action after tapping the Share button and scrolling to the bottom of the share sheet, tap Edit Actions.... Next, find MyNetDiary Recipe Import action in the list and turn on the switch next to it. You can also tap the green plus button to the left of the action name to make it one of your favorite actions. Finally, tap Done in the top right corner of the screen.
