Network Tools II is an Android application created with a simple idea: 1) Define some Internet-connected resources and equipment like websites, servers, smart devices, surveillance systems that will be monitored. 2) Define time intervals when this equipment should be monitored. 3) Have an alert as soon as possible when this equipment stops working. Network Tools II works like a watchdog. It sits in your pocket and monitors the equipment whose trouble-free operation is important to you. It uses the Android system scheduler and consumes zero CPU when it is not active. The application notifies you when the trouble appears, probably even before you or somebody else may discover it.
