Dont even waste your time.

I wasted mine. The free app does absolutely nada. All that happens when trying any feature is a pop-up that makes you purchase the app. Why even offer a free version? Why dont you just attach a picture of a cat on a Roomba when you download the free app - it would have as much functionality as this does.
