A list of apps worth considering for users who want widgets and 
real-time analysis of what is happening inside their Android smartphone.
 Also includes tools that can tweak CPU settings and speed of your 
rooted smartphone.
Android is 
the most flexible and customisable mobile platform today and one has 
access to a number of apps with multiple uses. If you are one those who 
is interested in the hardware and wants to know what is cooking inside 
your Android device, then we have some apps that will not only give you 
access to system information but also provide certain tools to tweak the
 system hardware. Of course to change some settings you need to have a 
rooted Android device, so a word of caution for those who are new to 
Android devices.
CPU-Z
You probably have seen this on Windows 
as well where it tells you information about your hardware, processor 
speeds, clock speeds and more. The Android app gives you information 
about the following:
- SoC (System On Chip) name, architecture, clock speed for each core
- System information : device brand & model, screen resolution, RAM, storage
- Battery information : level, status, temperature
- Sensors
- SoC (System On Chip) name, architecture, clock speed for each core

System Monitor
This app gives information including OS 
Build, CPU, Memory, Telephony, Networks, WiFi, Storage, Battery, Camera,
 Display, Sensors. There are also some monitors including a CPU Monitor 
which displays a graph of the current CPU load, a Memory monitor which 
displays a graph of memory usage and a Battery monitor which displays a 
graph of battery usage. The app also has its own Task Manager, an app 
manager and a bunch of widgets which give you real-time information 
right on your homescreen.
You will require a rooted Android device
 for this application as it requires special administrative privileges. 
This allows you to change your CPU frequencies and also to use the 
highest supported frequency of the CPU which can help in gaining some 
extra performance.  You can also reduce the frequency of the CPU so that
 it uses less battery.

CPU Tuner
CPU tuner gives you access to control 
your CPU speed and in turn helps you to have control over the power 
consumption of your Android device. You can also overclock your 
smartphone, although it isn’t advisable as there are chances you will 
damage it. There are also some profiles that can automatically switch 
on/off services of the device like mobile data, Wi-fi, etc.  This app
