This is a family crowdsourcing app for shopping lists that helps Mom make fewer trips and get everything in one go. Each family member installs the app to their Android or iOS phone and manages their own lists. They each share their individual lists through the cloud with their Mom, who then has a big picture list of what everyone wants and what store. It is a Xamarin.Forms app that is cross-platform and backed by Microsoft’s Azure Cloud.  The app runs $3.50 per month per device; it is an invitation-only installation.

This is a demo of iOS, Android and Windows for you to see how it functions a bit:
