I've used their app for about a year and it worked well (most of the time). But I downloaded an "update" earlier this week and the app is pretty useless to me at this point. I log in okay, but now, to view my reservations, I have to enter a confirm number and the last 4 digits of my credit card. Not really very useful to me as a mobile app. Previously, it would just provide a list of all upcoming reservations. I wouldn't recommend getting the update at this point.
