CPU Spy is a simple app that allows you to monitor your CPU usage
This is just an app for monitoring, you can't modify nor your CPU frequency either any other parameter. You can check how much time CPU spends in each frequency state. Your CPU isn't always at highest performance: its frequency varies depending on the process you're executing. For example, you're in lower CPU frequency when airplane mode than over WiFi. You're in the lowest CPU frequency levels when, what's more, display is off.
CPU Spy shows 6 states: 1000Mhz, 800Mhz, 400Mhz, 200Mhz, 100Mhz and deep sleep. What's more it sows how many time you spend in each frequency and how much it represents out of the total. It also shows total state time and kernel info. You can reset/restore timers anytime.
In summary, an useful tool to keep track of what's going on your device's heart. Recommendable.
It also displays the current kernel information.

-Better tablet support (still work to do, though)

Very light app. It accurately calculates the time CPU spends in each state and hence helps to relate to the battery consumption. Perfect app ^_^
Does what it says and has no ads. Must have.
I have an 8 core note 3 with 1.9 Ghz clock, and the app says the phone uses only 650Mhz max clock speed...
Can anyone explain me what this app is all about as i am unable to figure it out..i hve installed this app and it shows different layers like 700 mhz 248 mzh,, sleep..as far as the reviews are concerned after reading a few i got to the conclusion that the battry life is better when the fone is in dead sleep..but how to achieve it.what is the use of reseting timers can anybody explain..most of u ha
