Disappointed so far - was expecting more

This company makes good apps so I was expecting the app to include some screening criteria, like which apps are no longer compatible with my version of OS X, or which duplicate the functions of other apps I have, but all I see is that it lists my apps and gives me a chance to check off the ones I want deleted along with their related files. Since I have for years had an app that always gives me the option to leave or delete related files whenever I delete an app, I fail to see the usefulness. I could do the same thing through the Finder. Maybe I am overlooking something?
