Startup Idea: Grocery Management and Tracking App

Startup idea to develop an app that allows users to find products and their prices in nearby stores, keep track of items in the fridge and set reminders based on their expiration dates. The app would enable users to scan barcodes for retrieving information about the product's shelf life.

I cook regularly and sometimes it's difficult to find the products that I want in one grocery store/market.

I will greatly appreciate an app where I can look up products/price in near by stores. It would also be great to track what I have in the fridge and for how long they'll last.

For example, by getting the barcodes, i can retrieve information about how long they last and have reminders from the app.
