HTC Home and Metro Home are the two popular clock gadgets available for Vista and Windows 7 operating systems. While the HTC Home brings the widely popular HTC Sense UI to Windows, HTC Metro adds Windows Phone 7 UI to the Windows desktop.
Horlonger is another simple clock application with advanced settings to personalize the look and feel of the clock. The current version of the clock features three skins, including Aero and HTC Sense (default).
As we mentioned earlier, there are cool settings to personalize this beautiful clock. You can find transparency level, position, and language options by opening Horologer settings.
