The app was confusing to figure out at first. It's slow to load all of the items and scrolling through them all can be frustrating cause sometimes you click on the wrong thing while trying to scroll. Voting on the rooms is frustrating as well. I hate the comparison voting which skews the results. You should be able to give stars on a single room at a time based in how well they followed the challenge. Last, you don't win enough gems or money for how much the items cost.
