CpuFloat is a floating app which monitors several key pieces of system information so you can monitor your device without leaving the application you are using.

CpuFloat monitors:
• Cpu frequency
• Cpu temperature
• Gpu frequency
• Gpu load; not normalised
• Gpu temperature
• Time awake and in deep sleep
• Battery current
• Battery temperature
• Network speed

Time
This counts the time your gadget has been active and in deep sleep, a battery friendly state. Sometimes apps don´t let your device go into deep sleep, this will shorten the battery time.

Temperature
If available the cpu and gpu temperature are shown. If not available you can choose the temperature sensor in the settings. This has been extensively tested on Qualcomm socs. On other socs this might not work as intended.

Cpu and gpu Trippoint
If the temperature gets higher than the trippoint temperature, it´ll turn red. You can change the value of the trippoint temperature in the settings.

Flexibility
You can choose what to monitor and where to show the floating window. CpuFloat can be a big vertical floating view with lots of information or a smaller, less intrusive horizontal view.

CpuFloat is a compact system tool with minimal permissions; vibrate, read sdcard, draw over other apps. There are no ads and it doesn´t use internet data.

Notice about changing app permissions on android M (6) and up :
Because of security reasons you can only change app permissions if there are no screen overlays or floating apps running, else you´ll get this error message:
Screen overlay detected.
To change this permission setting, you first have to turn off the screen overlay from Settings > Apps.
Just exit CpuFloat and try again, if it still doesn´t work, there´s another app using a screen overlay.
