A mobile app developed in React-Native for shopping which pulls/compares price data based on one or more parameters:
Location(distance), Price Range, Specific set of stores, coupons available
And finds the lowest price based a user-defined shopping list of groceries.
I.e. if a user defines a shopping list as:
1.Cheese 2.Bread 3.Crackers
Multiple lists will be generated from different stores, in the order from the smallest TOTAL price of the items.
Coupon lists are also generated for stores and attributed to items within the user-defined lists as available, and allowing them to scan coupons from their phone if the coupons are available online.
