Point in Time Wireless Monitoring.
Who's On My WiFi shows you all devices on your network over time.
You can easily tag and label devices that you know so it is easy to see if any unknown devices join your wireless network.
With background scanning option, the app will continue to scan your network every few minutes looking for unknown devices.
The latest version also includes online connectivity to the Who's On My WiFi Online subscription for historical reporting, real time alerts, and industry specific needs.
Official Version: This app is made by the same company that owns and publishes the Windows, Mac, and Online Subscription with the same name.
