The annual congress, which kicks off in Munich on 25 August, will be using a custom-made mobile app with a sponsored button for the first time.
The app is sponsored by Bayer Healthcare and the ESC invited Bayer to participate in the design process to find the best way to integrate them into the design.
The end result shows improvements in usability, easier navigation of the extensive conference programme, layout, design, and sponsor content.
The app includes the full conference program, personal programs, searchable lists, venue maps and note-taking capabilities. Attendees can share content with friends and colleagues via email, Facebook and Twitter.
The app is available in the iTunes and Google Play stores.
Jelmer van Ast of Conference Compass said: "In 2012, 45 per cent of delegates on average are downloading an event’s mobile app, compared with an average of 30 per cent in 2011.
"At the International AIDS Society’s event for 30,000 delegates in Washington in July, 14,500 people downloaded the application.
"More people have smartphones and tablet devices now and they are starting to expect a mobile event app. It is a trend we see increasing over the next few years.
"Our vision is for delegates to use the app all year round. We are currently working on a function that will allow users to set up meetings using the app."
Ben Hainsworth, Director of Congresses and Meetings Division at the European Society of Cardiology said: "It was great to work with such a committed, flexible and creative team. The app had all relevant features that we expected and our attendees were very satisfied with this new resource."
Conference Compass’ list of association clients includes the European Association of Cardiothoracic Aneasthesiologists, European College of Neuropsychopharmacology, European Orthopaedic Research Society and the International Society for Sexual Medicine.
The price of a Conference Compass app can range from £1,000 to £9,500-plus. Discounts are available for clients that book multiple conferences.
