URL Monitor is a free Android application developed by Robert Chou that checks the up-down status of web server hosts. It is a forked version of "Host Monitor," and it allows for an optional PATH where the program will do an HTTP HEAD instead of a ping. This program fixes crashes and works in Cupcake 1.5. It also has a new desktop widget that summarizes the overall status every 15 minutes, which can be added by long-pressing the home screen.

URL Monitor is a useful tool for web developers and website owners who need to monitor their website's status regularly. With its reliable and accurate monitoring, users can quickly respond to any server downtime issues. Overall, URL Monitor is a handy and straightforward application that performs its intended function well.
