Mac Address Ghost is an Android application that allows users to temporarily change their device's MAC address. The app is developed by diewland and is available for free in the Utilities & Tools category. It is a useful tool for users who want to change their MAC address without much hassle.

The app allows the user to save their MAC address as a profile to the SD card. The MAC address will be recovered when the device disconnects from the Wi-Fi network. The app also checks for root access, installs Busybox, and ensures that the correct interface name is used (wlan0 or eth0). The user can check the result with the command "ip link show [interface_name]".

Overall, Mac Address Ghost is a simple and effective app for users who need to change their MAC address. However, it is important to note that the app is not intended for illegal activities. The developer also offers a donate version for users who wish to support the development of the app.
