IP Scanner is a free Android application developed by Gulshan Singh, which is an Android port of Nmap. It allows the user to scan any hostname or IP address. The application is available only for ARM Android devices, and some of its features require root access.

The app is a useful tool for network administrators or anyone who wants to check the security status of their network. It provides a simple and user-friendly interface, which makes the scanning process quick and easy. The application also allows you to save the scan results for future reference.

However, the app has some limitations, as not all features are available without root access. Also, the app may not work on all Android devices, as it is only available for ARM devices. Overall, IP Scanner is a useful tool for network scanning, but it may not be suitable for everyone.
