Symantec hasn't used the name Disk Doctor in at least a decade. But that doesn't mean they don't own a copyright on it. Of course, if they've let the copyright lapse then the name is fair game. Still, this app is a pale imitation of what Norton Disk Doctor could do and hardly qualifies as any kind of doctor. It's probably true, though, that most of the people currently using Mac computers came to the platform after Symantec stopped supporting Norton Utilities on the Mac and have no memory of that venerable product. Which is what the developers are no doubt counting on. If this app were more robust I might give it a pass, but all it apparently does is invoke the Cron scripts built into OS X, which is to say, it does nothing that any of a host of other apps don't already do, some of which, like Maintenance, are freeware, and all of which have less pretentious names.

Oops! You're right. I missed the Snow Leopard link at the top of the page. I read the compatibility info at the bottom of the page and there was no link there among the Related Links to the SN version so I jumped to an erroneous conclusion. My bad.
