Each meal is then automatically kept in rotation or dropped based on the score (i can keep ones my wife and I especially like even if the kids don't). Each family member can choose one meal for the following week, or I can generate a random list for existing meals. I can search by cuisine, ingredients, score, and a few other bits of data.
The app also will print out a weekly shopping list of ingredients based on meals selected, AND will take into account what ingredients I have on hand. However, although the app does provide an accurate list of ingredients, it hinges on me updating the ingredients I have in my pantry and I don't typically do this as it is manual and too time consuming - It was neat to do an initial inventory of ingredients when I built the app, and the app does subtract ingredients out when used in meals for the week, but i no longer update the ingredients when I purchase from store each week.
So if you know how to code, you code probably just roll your own as I did. Then it will have all the features YOU want. But as others have said here, there probably will be a solution out there that will meet your needs.
