The official Congress app is free to download and allows delegates to search the programme by day, faculty, topic, target audience and track. It provides access to abstracts, ePosters, and webcasts of recorded presentations a couple of hours after the session has taken place. There are also full listings of industry events, the exhibition plan, an interactive map and a personalised agenda. Congress delegates also have the option to customise their profiles to appear in active participants lists, enabling delegates to contact other visible users and exchange electronic business cards. The app will be downloadable prior to the Congress, and for those who wish to download onsite, the ERS will provide all relevant information at the registration area. Once the app is downloaded, it works independently and does not require continual connection to the internet.
