The Gearhead column has been keeping tabs on the best Android apps for IT workers. Here's the cream of the crop
Overlook Whiz is an Android widget for testing servers. After installation, you simply press and hold on any open spot on the home screen, and the "Add to Home screen" menu appears. Click on widgets then scroll down and click on Overlook Whiz. A configuration screen is displayed where you enter your target machine and service and select the refresh rate and other test attributes. The widget can sit on any of your home screens (I have a screen dedicated to monitoring the various services I rely on). Another hit! Overlook Whiz also gets a rating of 5 out of 5.
