NetStat

Netstat is a network scanning app that locates devices connected to the network, so you know who is using your Wi-Fi by the name of their device and IP address.
The full list of the app's features includes:
- device identification and scanning in the network
- general information about the network (IP, DNS, etc.)
- user's IP address and current geolocation
- device ping tools
- routing to a device or a website
- open ports scanning on devices in the network
- download and upload speed testing
- network scanning history
Before scanning the network, you can also select a device filter, so only certain devices will be checked and displayed after scanning (desktop, laptop or mobile).
