Quick answer
Simple CPU Stress test tool for Android
This program is a simple stress test tool for Android devices.

How to use: On Android 13 and newer, When this app started at the first time, it will show a dialog requesting notification permission. This is required to the app can continue processing even when its window is not open.
In the "Threads:" input field, enter the number of threads to use.
