Pesquisa & Compra is a free, Android-based app designed to make shopping easier for users. Developed by Carlos Quintanilha e Luiz Cláudio Alves, the app allows users to check the prices of products in all supermarkets in their city. The app uses the device's camera to scan the barcode of the product and display its price across all supermarkets. If the camera fails to scan the barcode, the user can manually input the code using the device's keyboard.

With Pesquisa & Compra, users can make informed decisions about their purchases by comparing prices across different supermarkets. The app also serves as proof of a lower price in another supermarket for those shopping in stores that promise to sell at the lowest price in the city. The app is a must-have for shoppers who want to save money and time.
