5 Best Free Wi-Fi Apps

Free Wi-Fi analyzers & network scanning apps

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.

All of these apps are different, but a Wi-Fi analyzer might check the network for which devices are connected to it, the strength of the channel, the IP address of the devices and network itself, open ports, and more. 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 of the connection.

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.

The best Wi-Fi apps listed below work on a variety of devices, including mobile devices like smartphones and tablets, but also computers.

Fing free Wi-Fi app for Android
What We Like
  • Great network discovery tools.

  • Highly rated mobile client.

  • Updates often with new/improved features.

What We Don't Like
  • Login requirements to "unlock" some basic behaviors and trends.

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

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

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

Other features include a traceroute option, alerts for when the state of a device changes, an internet speed test, a live internet outage map from around the world, and an export option to save the list of connected devices.

Fing is a free Wi-Fi app for Android, iPhone, and iPad which also has desktop apps for Windows and Mac available.

  • Portable mode option for Windows.

  • Fast performance.

  • Really just a glorified scanner.

Angry IP Scanner is another free Wi-Fi app that simplifies network scanning. It's portable so it can run from a flash drive or other temporary location.

This program is useful if you need to find every device connected to your network, as you make a scan between any two IP addresses. It even automatically determines which addresses to scan based on the default gateway's address.​

In addition to identifying a device's IP, ping response, hostname, and open ports, the settings in Angry IP Scanner let you toggle on other fetchers to see details like NetBIOS info, the MAC address, and the MAC vendor.

Advanced settings let you change the ping method and timeout, define which ports should be scanned, and eliminate all devices from the results list that either doesn't respond to a ping or have no open ports.

You can copy all the details of any device to the clipboard as well as export some or all of the results to a TXT, CSV, XML, or LST file.

This free Wi-Fi app is for Windows, Linux, and Mac computers.

SoftPerfect Network Scanner is full of basic networking features like finding the ping response of every device on the network, plus their hostname, IP address, and MAC address, but there's much more this app is capable of.
