I use Paprika as well. The most useful feature is that I can add a bunch of recipes to the calendar for a week, and then auto generate a grocery list synced to my phone. You can also easily scale the ingredients. I have a couple of friends who use it and say it clips recipes in foreign languages pretty well (but no ingredient scaling).

There have been a lot of apps in this space which were better but also subsequently abandoned by the developers. Almost all of my friends switched over to Paprika because they got tired of switching again and again.

Paprika has a really nice web clipping feature. Enter a URL, and it extracts the recipe, separating out the ingredients list from the instructions. It will even extract recipe from the comments in Reddit threads. I'll be walking through the OP's site for interesting recipes, and clipping them with Paprika.

Cheftap has this as well, and it works great. Rarely you have to edit it to fix something, since most of the time it pulls it from any website properly.

I have not used paprika myself so unfortunately I cannot comment. But if there are any features that you would like me to focus on for the next updates of feastgenius let me know and I will work them in.

I think the biggest feature for most people is that they don't want it to dissapear after 10 years. Many people put a lot of work into their recipe collection and wants it to be available for the kids when they grow up.
