These free Wi-Fi apps will help you scan to find open networks around you, or to analyze your own Wi-Fi network to keep track of devices connected to it and how secure your network appears to others.

The free Wi-Fi analyzer apps analyzes any Wi-Fi network and will tell you the devices connect to it, the strength of the channel, the IP address, and open ports. It's really a must have when you're checking out your own Wi-Fi network to see how secure it is.

There are also free Wi-Fi scanners here that will help you identify networks around you, telling you if they're open or closed as well as the strength. 

You'll also want to find free Wi-Fi locations so you can get online cheap, whether it be through your ISP, at a near location, or to locate public Wi-Fi hotspots.

Fing Network Tools (Desktop & Mobile)

Fing iPhone app

What We Like

  • Great network discovery tools.

  • Highly rated mobile client.

  • Works with a device (purchased separately) to add an extra layer of security to your network.

What We Don't Like

  • Login requirements to "unlock" some basic behaviors and trends.

  • Upsells in the app for the Fingbox device.

Fingbox is my favorite free Wi-Fi app because it provides very useful information for wireless networks but isn't at all hard to use.

When Fingbox is first opened, the app will automatically scan the network you're on to find all the different devices that are connected to it. Their IP address, physical MAC address, and hostname are shown and can be easily shared and saved.

Clicking or tapping on a device shows even more information, such as its vendor, open service ports (RDP, HTTP, POP3, etc.) and ping response, as well as the ability to wake it up if Wake On LAN is supported.

Fingbox can be downloaded for iOS, Android, and Kindle mobile devices, as well as Windows, Mac, and Linux computers.
