About this app

This utility allows you to monitor a various system info in "always on top" floating window (overlay mode).
Available features:
- CPU Usage meter
- Free RAM meter
- CPU Frequency indicator
- 2g/3g/Wi-Fi Traffic meter
- Battery Level
- Battery Temperature
- Battery Current (mA)
- Wi-Fi Signal Level
- I/O Activity
- Time/Date indicator

- Number of fixed GPS satellites
- SD Card free space
- Most resource-intensive processes
- Task Killer
- Audio VU and visual equalizer
- CPU temp on some devices

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.

Great app! Would be better if it had the option to be a widget or a side loading drawer or even a persistent notification with a couple of starts always in the notification tray, just so it's not always in the way of other apps. Certain apps, this always being on top is great. But for other apps, it gets in the way. just those options would be awesome

Don't waste your time - not only are CPU and GPU temperatures missing, the adverts are absolutely obnoxious, obtrusive and over-the-top. During configuration a typical small banner ad is shown (no problem) but when you click "enable" to start monitoring - BLAM! A full screen, full video with sound advertisement suddenly pops up (scared the living $H!t out of me - tv box). Uninstalled. I'd never even think of trying another app from this dev.

I have many separate monitoring apps that display in notification, but this one takes the cake and displays literally EVERYTHING. Wish there was a way to reorder labels. (Tab A7) Update: CPU freq and charge rate do not work on Tab S8 ultra.
