The “Fair Prices” campaign is a public-private initiative promoted by the Municipality of Rosario, the Union of Warehousekeepers and Retail Merchants, and representatives of recovered local companies with the premise of offering products from the basic food and cleaning basket at prices really accessible.The app allows the neighbor of our city to know the products and prices that make up the basket, as well as the attached commercial premises closest to the current location of the citizen.The mobile solution developed implements geolocation to visualize the distances to the closest shops, as well as to know the optimal route of arrival at the establishment. The telephone number of the shops is also included so that the neighbor can be contacted by that route and thus place the order from there, avoiding queues at the commercial premises.The development of this application has been a joint work between the Ministry of Social Economy, the Ministry of Production and Rosario Mobile.We invite all citizens of the city of Rosario to get involved and participate, as this project must be a collective construction of the entire society, either by suggesting new products that are not yet included in the basket, inviting the warehouses in their neighborhoods that They are not yet attached to the addition, reporting those businesses that do not meet the published prices, proposing new features for the app ... any contribution will be welcome.
