'PIRS:Site' offers the perfect offline solution to access and manage your project documents and important correspondence. Simply synchronize your project data to your device and have the latest revisions and up-to-date information at hand anywhere, anytime, regardless of an available internet connection. As additional great feature, the 'PIRS:Site' download manager allows you to download every attached file directly to your device. Working with eventually outdated drawings on site or fighting with large paper files is therefore no longer an issue. You can even add your annotated documents, pictures and videos directly on site and upload all new files with the next synchronization. Working with PIRS, our project based document and correspondence management system, you are already able to easily manage and share all documents and information, sent and received from external or internal project members, suppliers or customers. As an extension of 'PIRS', 'PIRS:Site' allows you to stay on top of your project even when you have no internet connection or access to your company servers."
