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

- 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

A very good application for determining a lot about your WiFi connection. It would be a very useful tool to some setting up (or already has) there WiFi AP's and changing which channels they are broadcasting on. A very respectable application. People do not realize what dangers there are with embedded ads. It is good to see that not every developer is trying to get into your wallet.

Awsome. But I have a feature request. There needs to be a sound that can be turned on the sound would be a toan around 30Hz if the signal strength is -85 db, but if the signal strength is up around -10 db, then the toan would have a frequency of around 5KHz. So now you can use your phone as a WiFi adjustment tool. Place the phone in the room you want to check the WiFi strength, turn on the toan, and hear the signal strength from the other room where you router is, and adjust the antennas.

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.
