Garbage in, Garbage out
I tried using this app durin recent visits to all 4 Magic Kingdom parks. The app worked well, although some of the navigation is confusing. The significant issue, though, is that the data for wait times comes from other users, with the only sanity check being that they need to be "near" the attraction they are updating. While the times were usually close, we ran into cases where somebody entered absolute nonsense - for example reporting a ride closed, or hour-long waits when there were none. It would be better if users had to log in to provide data (see GasBuddy for an example). I switched to Disneys offical, but heavy weight, app, because the info was correct.
