CPU Info is an open-source Android application developed by KG Soft that provides detailed information about the hardware and software of your device. The app displays the CPU specification, including the current frequency on specific cores, GPU specification, RAM and storage state, internal and external storage, and SD card. It also shows the display metrics, Android OS details, sensors data, battery status, and WiFi and Bluetooth MAC address (on older Androids). Additionally, it provides audio card info, native libraries used in other applications, and CPU and battery temperature monitoring.

The app also allows you to manage installed applications and check running processes (on older Androids). The entire project is open-source and available on Github, where users can post ideas and report issues. However, some of the features may not work correctly on Android O and newer versions.
