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.

THIS is ONE of the BEST APPS out there! Dude! I will be doing a FULL review of this APP. IT IS AMAZINGBALLZ!!! Love it! It takes about and hour or 2 to really get the hang of it there are so many options. And MAN can you TWEAK this thing. The only complaint I have is that the FONT and TEXT can not be parted more for clarity or spread apart. Maybe have individual boxes for each text would be cool! Also the graph is green and the text is green on the bottom, Not sure how to change this to red or another color. Also, if the Bar graph could flash if it was a 100% that would be cool! I have this on my Samsung Pro Tablet and on my ZTE ZmaxPro. Man, this phone was the best thing ever got! One day I would love to see a 3D mode one day. That would be cool! Font size is a BIT small, but there are TONS of options so that is understandably okay! Man, those Android Developers are AMAZING THANK YOU! I can't say enough good things about this! I will be doing a FULL review of this app soon! _=HOW I"M USING IT=_ I have a Big screen TV in the back of my Van, so I use to just connect to it via HDMI, but as of late, I am just using the Screen share from Samsung Pro Tablet to the Amazon Fire stick and am displaying this there. I also have it on my phone, and MAN IT LOOKS! Best Feature is the VU Meter. It really does work great when Playing music. Not from the Microphone. I'm going to have this app on my phone forever! FULL 100% COOL RATED by iMickey503! .

This is a most excellent app if you want to have the temperature in your status bar. It also has many more features but I haven't even looked into yet. This is an amazing software I commend you on your programming skills. I sent a couple of emails about cool tool about cool tool Pro to the developers email. Thank you for your work on this project.

Thanks for fixing the bug that was intercepting screen taps even when the tool was invisible in landscape mode. That was so frustrating I almost had to uninstall this otherwise wonderful app.
