The functionality that it strives to achieve is good but it is executed poorly. Interacting with the app (on 2 different iPhones - an 11 and a 12) has proven it is clunky, frequently poorly responsive to touches, takes a great deal of time to load initial data, doesn’t save your favorites/schedule to a profile that can be loaded onto another phone (ie when I sign in to both, the second phone doesn’t have my schedule automatically saved when using the first phone), and when signing in there is no indication of success or fail - if it failed it simply re loads a generic page and continues to ask you to sign in rather than clearly stating it didn’t work and please try again. Also the failed login was from using the alternate email that I have (which I have since listed as my primary, but it wasn’t working so I used my old email and then it was successful in signing in). For a large national conference in emergency medicine, this app is terrible and needs to be polished.
