MacKeeper is an all-in-one system utility for cleaning, optimizing, securing, and controlling your Mac. While Standard ($59.95) and Premium ($89.95) licenses exist in addition to the "Lite" version ($39.95), the software itself is the same for all three. (The more expensive licenses come with additional services.)
MacKeeper includes 16 different tools for system maintenance: Internet Security, Anti-Theft, Data Encryptor, Files Recovery, Shredder, Backup, Fast Cleanup (which includes subtools for deleting unnecessary binaries, caches, languages, and logs), Duplicates Finder, Files Finder, Disk Usage, Smart Uninstaller, Update Tracker, Login Items, Default Apps, and Geek on Demand.
For the most part the sub-apps on this impressive list are self-explanatory. However, they're not all justified by the price tag. For instance, the MacKeeper website lists Login Items on its own as having a $5 value. Five dollars my foot, it's exactly the same as the Login Items feature of Mac OS X's System Preferences. And the claim of "92% savings" is false even with the arbitrary per-tool prices provided, since the Lite license does not come with Geek on Demand service.
Regardless of price point technicalities, having all these tools in one place does add value in and of itself, and each works adequately for the average user.
