Originally popular on Windows PCs, the Android version brought these capabilities to mobile devices. It utilizes a technique called "ARP Spoofing" (Address Resolution Protocol Spoofing). In simple terms, the app tricks other devices on the network into thinking that your phone is the router (gateway). Consequently, the data traffic from other devices flows through your device, giving you the power to allow or block their internet access.

NetCut is a network monitoring and management application originally designed for Windows, later ported to Android. Its primary function is to scan a local area network (LAN), identify all connected devices, and provide the user with the ability to cut off internet access to any of those devices with a single tap.
