Who Is On My WiFi is an app that allows you to see who's connected to your wireless Internet. It provides a lot of the same information that many routers do when accessed via a web browser, but it's easier to set up and access than these built-in landing pages, and it also can be set to alert the user to new Wi-Fi connections. However, it can't tell you detailed information about the devices connecting to your Wi-Fi beyond the device's name and minor details, and support is limited.
