Beautiful Widgets has to be my outright favorite Android application of all time. I've installed this as the first purchase on so many friends phones and tablets I can't even keep count. It has been in the top paid, most downloaded, and editors choice lists for the Android market for the last year, at least. I don't know how many times on blogs, forums, and here at Android Community readers have said "What's that clock widget, or weather widget?" It is Beautiful Widgets, and right now it is FREE.
