Can we developed this

I want to make an app that shows if an item is available or not. That has only 3 pages the first page is search bar second that shows lists of shops where the item is available third one is when they touch it that takes them to specific shops and where they are located and some info about the shop. So the question is the item’s availability must be updated daily by the shop owners can i make this kind of app also the users must be online to see if it is available or not so please help me if you also have any other idea i am all ears it is urgent also i think it will help lot of people

Yes, you can build this type of app using Xano or backendless as your backend, and Appgyver as the frontend.
