wsb is an offline-first app for seafood counter management. Track temperature logs, manage batch inventory, and monitor losses. Record incoming deliveries with supplier info, assign batches to display cases (Main Counter, Back Cooler, Freezer), and calculate expiry dates from shelf life. Monitor cold-chain compliance by logging temperatures per display case with automatic incident detection for out-of-range readings. Manage inventory with FEFO (First-Expire-First-Out) batch allocation for sales, track losses by type (Waste, Trim, Spoilage, Return), and analyze performance with interactive charts showing loss distribution and cost impact. Features a Material 3 dark theme, real-time stock views by display case, expiry status indicators (Fresh, Soon, Urgent, Expired), temperature risk assessment, and analytics. All data is stored locally on your device with no cloud sync, ensuring privacy and offline functionality. Suitable for seafood counter managers, fish market operators, grocery store seafood departments, and restaurant prep areas who need inventory management, temperature monitoring, and loss tracking in one app.
