What does this app do? I clicked "start", and was plopped down on the home page with a frightening amount of information. It would be nice if you explained in a sentence or two what the app does, and why I should use it. I see that while I clicked away to write this I got the "welcome to statgadgets" popup. I still don't know what the data sets are or why I would want to "analyze" them.
