Port Detective is a free networking tool developed by Mohammad Adib for Android users. This app is designed to detect open ports on hosts on the local network. The port scanner algorithm is speedy and capable of scanningports in around five minutes on a single-core processor.

One of the app's main features is the Port Encyclopedia, which allows users to quickly look up the function of a certain port. The app stores a local database of defined ports, but users can also access the latest information online. This feature is especially useful for users who need to identify ports that might be compromised or are being used for malicious activity.

Port Detective has been recently relaunched on March 25, 2019, with a rebuilt version for the latest Android OS. It is a simple, easy-to-use tool that can help users identify open ports on their local network and ensure the security of their devices.
