Listas Simples

The application is a mobile solution designed for capturing, organizing, and managing product lists through a table-like interface. It allows users to manage editable rows with key information for each product and automatically calculates the total for each row and the grand total. Additionally, it integrates a simple persistence system based on CSV files saved in the application's internal storage, ensuring data availability across sessions without requiring permission configurations or cloud services.

The app functions as a simplified spreadsheet focused on a very specific use case: registering products with quantities and unit prices, marking rows as selected (checked), and obtaining a final total only for the selected items, while maintaining easy export/import functionality via a universal format (CSV). This combination offers a familiar experience for users who frequently work with lists or inventories, but in a mobile environment optimized for rapid data capture.
