I am so incredibly disappointed in this app. I bought it thinking it would be very useful and it only functions as a guest list that wont let me transfer names from one list to another or easily update any information. Ive had to enter the information for one person five times because theres no centralized way to edit a person and you have to type them in every time, and then you have to REenter them if you get their address after you put their name on the list instead of just updating a pre-existing name. When I wrote to the developer about it he said the update was coming that allowed people to transfer from list to list, and its still not here. My wedding is May 14th 2011 (Ive had this app since December 27th 2010), so I ended up having to write my lists out on paper, and I bought the app specifically so I wouldnt have to resort to that. My fiance warned me that I probably shouldnt buy this app. I wish I had listened to him. The interface is a little clunky, and while the graphics are nice, the actual utilities are kind of useless. I got more out of TheKnot.com in twenty minutes than in three days of fiddling with this app. Without the ability to easily transfer people from one list to another (at bare minimum) and post the persons address (and make it edit-able) in their little profile area, it makes more sense to just write them down on a piece of paper and deal with the awkwardness of having to carry around four notebooks. Additionally, without the ability to filter the guests by His and Hers, it really makes seating difficult. Overall, I would like my money back. Also, the only reviews allowed on this page seem to be Positive ones, and the reviews have to be reviewed before they can be posted, which makes me wonder just how many other people were disappointed and how much money could have been saved by an honest reflection of peoples experience with this app. I am /very/ unhappy with this app and the service experience Ive had with it.
