If you rely on your smartphone or tablet, and you need to work offline, switch to the mobile app. The IV2019 app will be available from the Apple Store or the Google Play Store. There is no need to login for generic use; however, to import your personalized agenda from the cloud platform, the app must be able to identify the user. Also, login is required in order to access critical information (e.g. profiles of other conference attendees), as well as copyrighted data (i.e. proceedings papers).
