【實用商業app】Backflow Prevention Survey|最夯免費app-綠色工廠好玩App

This application for iPad is used for making surveys by Backflow Prevention Services. Surveys include site information (owner, location, etc.) and actual survey information (backflow devices found or required, their characteristics, etc.). The application has it's own local database, which synchronizes with the main server if correct username and password are provided, so offline inspections are possible.
