WiFi Analyzer (open-source)

VREM Software Development

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

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.

Ratings and reviews

Edit: someone on the development team sent a comment super fast. My problem is Androids fault, not the app. I also missed the experimental "disable WiFi scan throttling". That seems to have fixed it. Great app. Original review:Loved this app, but on my Motorola it no longer updates the AP list in any sort of reasonable time. I have to kill the app and reopen then sometimes it updates. I can leave a building with WiFi and 20 minutes later it still shows the access points that I'm no longer near.

This would get five stars except that it doesn't detect everything. I noticed that if I open the app switch on and switch off the Wi-Fi that I get a completely different list of APs. I use this one in combination with another one so that each one can verify the other. This one is far better than the other one because there are no ads and it seems to work better but it does not detect everything.

The app monitors detectible wifi signals in real time. Another reviewer claimed the app no longer does this, but it does it for me. It works great, has options to show results in chart form by channel and number of connections on each along with signal strength and another graphically presented. It's excellent, very quick on my rooted and debloated moto Z2 Force on stock android 8.0.0 -- I rated 4 rather than 5 because I'm in info systems and have seen (very expensive, not open source) software!
