OS Monitor

OS Monitor is an app that monitors all the processes running on your Android. Basically, it's like Windows Task Manager for Android.

When you open it you’ll see a list of all currently running apps. Simply click on any app to see detailed information on it, including the amount of memory it's using or exactly when it started running. You can kill any process by simply tapping the screen.

In addition to displaying all running processes, OS Monitor can also provide info about your CPU's performance, the amount of memory you’re using, and how much battery you have left. All this information appears right on the status bar.

OS Monitor is a process-monitoring app that actually offers many more features than most apps of this kind. For example, in addition to monitoring the parameters of your device's hardware, it also lets you see all available tpc or udp connections.
