We took over the maintenance of an internal Xamarin Forms mobile application and associated server-side application written in Java, for ACO, one of the world leaders in drainage system production.
The application is used to record drainage problems in production plans, which are subsequently evaluated in order to comply with applicable regulations and, if necessary, propose a specific solutions if defects are found.
The app is optimized for use on iOS devices (iPhone, iPad).
Due to the end of support for Xamarin Forms, we have successfully migrated the application to Flutter.
The application contains a large number of data entry screens with an emphasis on validation and consistency. The main functionality consists of gathering information about drainage issues and collecting photo or video documentation. The application can work fully offline and synchronize with the server once the connection is restored.
