The Prices and Markets Observatory is a free Android application developed by Junta de Andalucía. Its purpose is to provide pricing and market information to a wide and diverse audience, including professionals involved in the marketing chain of agri-food and fishery products, the auxiliary industry, trade press, consulting firms, and the general public interested in having timely and accurate prices recorded by the main Andalusian agricultural and fishery products information. The application offers information on various products, including olive oil, horticultural greenhouse production, strawberries, and citrus, as well as representative fishery products such as sardines, anchovies, white shrimp, sea bream, and shrimp. The application allows users to track price formation along the supply chain and offers prices in up to four different trading positions for agricultural products and two positions for fishery products. The user can access the last available price, the price of the previous week, the price of the same week of the previous season, price trend graphs for the last eight weeks, and all publications of different sectors.
