NetCut is a tool which lets you block other people from accessing the Internet on your local Wi-Fi network. In order to use this application you need to know that your device must be rooted. If you don't have superuser privileges then many features included inside this app won't work. The user interface rocks a minimal design in which you can see a list containing devices connected to your wireless network.
In order to block someone you'll just have to select the device and tap the proper button. Applications like this one are very handy when you're suspecting someone of using your Wi-Fi connection without your approval. Another way to prevent this from happening is by setting a harder password for your wireless hotspot and only share it with people you trust.
In case you're not sure if a user has been blocked, you can check again by scanning the network once more. Another handy feature is the ability to assign names that can easily be remembered to devices connected to your network. All detected users come with additional information like IP address, name, MAC address, device brand, etc.
