This app, although entertaining, is expensive and the voting appears to be fixed by the app. As a professional designer, I've been doing an evaluation of this app for the last month. The costs for purchasing quality materials are very high. And sadly, if you win too frequently, the app sets your account to always lose on the Daily Duel and keeps your account from placing 1st for a period of time. Save your money, there are other interior design apps to try instead.
