Better than carrying printed program App is quite effective in providing all necessary details of the various sessions, workshops, symposiums, etc. After selecting topics of interest/day, I was able to easily sync with my calendar. Allows for multiple sessions to be selected at the same time. This is not a 5 * rating because once you select a session it defaults to the beginning of the day's sessions. I found I could partially mitigate this annoyance by viewing the day's offerings by event type. It defaults to include all event types. Also, the app doesn't appear to be able to recognize when another device is being used. I first loaded app on my S4 and selected the sessions from same device. Then I downloaded app on my nexus 7. App on nexus does not detect that I already selected sessions.
Poor content and functionality Most options simply point to associated pages on DIA website and to other apps such as Facebook, Twitter etc. Missed opportunity to get content directly in the app.
