Also there is nice real time graph on background.
Press Show Panel button to enable dashboard. You can drag floating window over the screen or double tap to open settings. See video and screen-shots for details.
This application allows you to:
- Easy diagnostic problem processes that consume resources excessively.
- With Cool Tool you can monitor full-screen applications (games, video players, browsers).
- Monitor your Internet traffic without closing the browser window.
- Make your battery level always visible, with accurate percentage scale.
- Monitor how good your CPU governor switches between CPU frequencies in idle/stresses
Tips:
Customize the appearance of the panel using color picker dialogs. Also you can adjust transparency and size of the panel in Sliders section.
Tons of gauges could drain your battery very quickly. Uncheck the features that you do not need. Btw, Cool Tool went to sleep and do not draw anything when your display turns off. It is for power save.
ps: If you want to help me localize app into your native language, let me know.

Cool Tool - system stats APK: questions and answers
Can I install this APK over the version I already have?
Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.
Is the Cool Tool - system stats APK safe?
No one can promise that a file is safe, but some things can be checked. The source store flagged this file with a security warning. After downloading, check that the file's MD5 is 406d30d00413cf0a6679c72514d3a42f.
