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
- Estimated Distance to the Access Points
- Export access points details
- Dark, Light and System theme available
- Pause/Resume scanning
- Available filters: WiFi band, Signal strength, Security and SSID
- Vendor/OUI Database Lookup
- The application has too many features to mention them all

Notes:
- Android 9 introduced Wi-Fi scan throttling. Android 10 has a new developer option to toggle the throttling off under (Settings > Developer Options > Networking > Wi-Fi scan throttling).
- Android 9.0+ requires location permission and location services to perform a WiFi scan.

Even on Android 9, which has wifi throttling that can not be disabled, this app does an excellent job, provided you are a little patient. This app is a great public service, as good as or better than most of the for-profit stuff out there. Highly recommended as a way to figure out what wifi channels you should use/avoid, whether the "auto" setting on your router is being sensible in choosing wifi channels (often not), and troubleshooting interference issues.

I absolutely LOVE this app! It's indispensable for me. I live in an apartment complex in India, and pretty much every flat has their own WiFi so there are usually several dozen routers in range at any given time, all interfering with each other. Auto channel selection doesn't really work properly when every single 2.4 ghz channel is occupied with multiple routers. This app makes it easy to find the least occupied channels, the least of all evils for fastest connectivity. Thank you!

Great, free, and open source, does what it says, uses the least permissions possible. Also has a time graph that demonstrates signal strength of all WiFi in range on time so you can see and follow which fall in strength suddenly or changes when something happens. Cons: I didn't find a real speed test of the network, it indicates only the nominal speed, which in my country is pretty much meaningless. Overall: great job. Thank you.
