Most users stop at "change the channel." Kevin Yuan’s analyzer is capable of far more.
For users who do not understand RF theory, this feature provides automated advice.
Your Zoom calls drop at 1:00 PM every day. Open the Channel Graph at 12:55 PM. Watch as everyone returns from lunch and their phones auto-join the 2.4 GHz network. The graph spikes. You use the data to argue for a second Access Point in the breakroom. The board approves it because you have screenshots from a trusted source. wifi analyzer kevin yuan
Most analyzers show current signal strength. Yuan’s build introduced a persistent time-graph overlay. As you walk from your basement to your attic, the app builds a historical chart of an AP’s dBm (decibel-milliwatts). This is crucial for finding dead zones—if the line drops into the -80 dBm range (weak signal) or spikes with jitter, you know exactly where to place a mesh node.
This is a targeted diagnostic tool.
Kevin Yuan designed an interface that balances technical depth with user-friendliness. Here is a breakdown of the three primary views.

Unlike the basic WiFi status menu on your phone, this app provides real-time graphs, channel ratings, signal strength histories, and interference detection. Most users stop at "change the channel
Kevin Yuan, an independent developer known for creating clean, ad-supported but non-intrusive utilities, built this app to solve a fundamental problem: Most people don't know why their WiFi is slow, and the built-in tools are insufficient. His analyzer transforms your smartphone into a professional-grade spectrum scanner.
Getting started with the WiFi Analyzer by Kevin Yuan is straightforward. However, due to changes in Android’s location permissions (Android 8+ and later), there are a few hurdles to understand. Open the Channel Graph at 12:55 PM
