About this app

Optimize your WiFi network using WiFi Analyzer (open-source) by examining surrounding WiFi networks, measuring their signal strength as well as identifying crowded channels.

Users' privacy and security is a huge concern these days and WiFi Analyzer (open-source) is designed to use as few permissions as possible. It asks for just enough to perform the analysis. Plus, it is all open source so nothing is hidden! Most notably, this application does not require access to internet, so you can be sure it does not send any personal/device information to any other source and it does not receive any information from other sources.

WiFi Analyzer is under active development by volunteers.
WiFi Analyzer is free, has no-ads and does not collect any personal information.
WiFi Analyzer is not a WiFi password cracking or phishing tool.

Features:
- Identify nearby Access Points
- Graph channels signal strength
- Graph Access Point signal strength over time
- Analyze WiFi networks to rate channels
- HT/VHT Detection - 40/80/160MHz (Requires Android OS 6+)
- 2.4 GHz, 5 GHz and 6 GHz WiFi bands (Requires hardware support)
- Access Point view complete or compact

- Export access points details
- Dark, Light and System theme available
- Pause/Resume scanning

I have used this app for years across many Android tablets and phones, and it still works great for viewing all WiFi access points in the vicinity. Can't ask for a more detailed view of broadcasting SSIDs really. Also appreciate the channel graph view to see which APs are improperly configured for channel and bandwidth. Most of all no annoying ads intruding over the screen like the other app of similar name.

This app is great, does what I need 95% of the time. Its free and safe and ad-free. Folks whining about nitpick things below do not understand the importance of those three attributes. Free, safe, and no ads. Plus I keep finding great features like clicking down through a stack of stations on the same channel. Support open source folks, because it's good for you.

The only app I could find which shows the channel width used by each network. Other apps only show the "primary" channel for each network. Short of a true RF noise analysis, looking at the primary channels in use alone isn't enough to tell which channels are free. This app also has good features for filtering and pausing updating.
