WPSApp for Android is a

Wi-Fi Protected Setup (WPS) pin calculator and connector

. It[SQ]s designed to help users connect to Wi-Fi networks using the WPS protocol, sometimes even when the WPS feature is disabled on the router.

Essentially, it attempts to bypass or crack WPS PINs to gain access to a Wi-Fi network.

This is considered ethically questionable and even illegal in many jurisdictions, as unauthorized access to a Wi-Fi network is a violation of privacy and potentially a crime.

While the app might claim to be for legitimate purposes, like connecting to your own network more easily, its core functionality opens it up to misuse for unauthorized access to other people[SQ]s Wi-Fi. Use of such an app should be undertaken only if you have explicit permission from the Wi-Fi network owner. Otherwise, it[SQ]s strongly advised against.
