How does the offline access work? What kind of content is available offline?

When you have internet access Napp syncs all your content and keeps it up to date. You can also access your PDF files, when you are offline. You just have to download them in advance. So if you know that you will be out of office and possibly without internet access, it is a good idea to download the publications that you will need. When operating offline with no internet connection, all functions (except the audio/video content which is streamed directly to the device) will be available.
