Hard to use, even Disney staff couldn't find items on the app (like my park ticket). When we found the ticket, we had to take my phone out of its case to scan at entrance and every lightning lane - was a hassle. Also, got suggestions on the app that made "my day" a mess to find rides/shows/etc I planned. Went to Universal the day before and their app was user friendly, convenient, and favorites area made my experience so much better and efficient. A good app really makes a difference.
