This is the software publisher's description.

Your computer is like a car: if you do not tune-up your PC regularly, you may see computer problems like programs and devices that don't work, bugs and security holes, frequent crashes, and a s-l-o-w computer.

RadarSync is a comprehensive program designed for updating your computer in order to keep it safe and running well over the long term. With RadarSync, you have the peace of mind when you know that everything's been taken care of for you: you don't need to know what's installed on your computer, who the manufacturers are of the different parts of your computer, or how to identify the exact file that your computer needs. Unlike other update programs, RadarSync finds updates for hardware and software.

This comprehensive solution means that you get all the bug fixes available, all the new features you want, all the security holes closed up, and all the functionality restored for your computer. And unlike other drivers sites, RadarSync doesn't depend on a static database of drivers created and maintained (or not) by human beings. RadarSync uses its smart update technology to find exactly which drivers you need and finds you the right driver every time -- from wherever it's located, or wherever it's moved to. In addition, using RadarSync's Oops Protection feature, you can be confident that that you'll be happy with the results of an update - or else easily turn back the clock to the way things were before you installed the update.

Note that this is the free version which doesn't offer automatic updates, direct download links and the 'Oops' protection, amongst other features.
