While setting up a WiFi connection is simple, optimizing it for performance is not everyone’s cup of tea. However, with the free WiFI Analyzer app for Android, you can easily analyze the existing WiFi networks around you and find a less crowded channel for your wireless router.

When you launch the app, it displays a graph with different WiFi networks around you in different colours for easy identification. The graph live updates to show the signal strength of each WiFi network along with the channel number that each network is using.

The signal graphs tell you which channels are free to use and what kind of security is being used for each WiFi network as well the brand of router used with a network. Armed with all this information, you can set your personal WiFi network accordingly for better range and speed.

You can also set the scan interval from the app settings along with the selection of colours for the graph. Moreover, the app also lets you select individual channels to scan in both 2.4Ghz and 5Ghz frequency.

The app is ad supported.
