From the (super short) Appscope listing:

Personal recipe keeper and manager. Share recipes, grocery lists, and meal plans.

And from the fuller listing within the app's 'home page':

• Store all of your recipes in one place
• Assign labels to your recipes and filter by label
• Powerful search within your recipe collection
• Send recipes and notes to your friends and family
• Create collaborative shopping lists and meal plans
• Clip recipes directly from the web
• Import from Pepperplate, Living Cookbook, and Paprika
• Export your recipes in multiple formats for data portability

The URL to tap on or type in is recipesage.com/#/welcome.

Of course, you can turn this into an 'app' yourself with PAWA or just pin it 'as is' on your Start screen. Or just add it as a 'Favourite'. It's up to you. If you're confused by the different PWA options then check out my feature here.

Here's the PWA in action, using promo screens because of the amount of actual recipe detail(!):

Web-based but a perfect PWA for smartphones, including inside Edge and Windows 10 Mobile, you need to sign in, but then you get your recipes remembered across devices, so it's worth it; (right) some likely recipes that I'd never have thought of!

Digging into a recipe's details; (right) there's a fully integrated shopping list system too, with awareness of which ingredients are in which recipe.
