CPU Stats is a free Android app developed by Panecraft Inc. that allows you to monitor your phone's CPU usage and frequency in real-time. The app displays usage details within your phone's status bar, making it easy to keep an eye on your phone's performance.

CPU Stats supports a wide range of devices, including 6 and 8 core CPUs, single core, dual-core (NVIDIA Tegra 2), and quad-core (NVIDIA Tegra 3) processors. The app also has two notification icons for 6 and 8 core CPUs, making it easy to differentiate between them.

One of the best features of CPU Stats is its status bar notifications for CPU usage and frequency. These notifications appear in real-time, allowing you to quickly check your phone's performance without having to open the app.

Overall, CPU Stats is a useful utility app for anyone who wants to monitor their phone's CPU usage and performance. It is compatible with Android 9.0 and is easy to use. However, it does not have any additional features beyond CPU monitoring.
