Free WiFi Internet - Data Usage Monitor

The dev team at AppWorld Infotech points out that this is not a hacking tool. It helps you discover and connect to any free Wi-Fi hotspot in your proximity only if the admin or other users previously shared the password.
The mobile solution has an easy-to-use interface and gives you quick access to lots of information about your current network, including its download and upload speed, internal and external IPs, MAC address, gateway, frequency, lease duration, and signal strength. It also detects all the devices connected to your WLAN, along with their IPs and MAC addresses, enabling you to recognize possible intruders in a flash.
Additionally, the software offers a vast number of IP tools that anyone can deploy straightforwardly. Scan ports, run Ping tests to check the latency of a particular host, use the Traceroute functionality to determine what path a data packet follows from one IP address to another, find out details over a specific domain through the Whois query, or check a domain name with the DNS Lookup tool.
The app also lets you create Wi-Fi hotspots, track data usage, adjust router settings, and more.
