A (s)imple, (l)ight(w)eight cpu widget, that displays cpu load without the need of any permission. No ads. 100% fat free! Only 23 Kb small so it won't eat up your device storage space. It updates only once per minute to extend your battery life. You can force a refresh by pressing the widget. (It is also a button)
This is a widget so you need to drop it on your homescreen it is not an app.
There is a bug/feature on Android 4.x systems with widgets. If you can't see the widget in the widget list, try starting the App slw cpu app which only tells you: "you doing it wrong" after this you will see the widget in the widget list.
If you like more of those simple, lightweight widgets which only ask you for the permissions they realy need and don't fill up you phone with Megabytes of data even if they need to do only a small job then check out the other SLW widgets.
