WiFiAnalyzer review
A focused, privacy-conscious Android scanner for channel and access-point analysis.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
WiFiAnalyzer is a free, open-source Android application from VREM Software Development for examining nearby Wi-Fi access points, channel usage, signal strength, and wireless bands. It suits people troubleshooting or optimizing a local Wi-Fi network who want direct visibility into surrounding networks without personal information collection or internet access for analysis. Its focus is practical local scanning rather than a cross-platform management system.
The app brings together several useful views for channel decisions. It graphs channel signal strength, tracks access-point signal strength over time, and rates Wi-Fi channels based on surrounding networks. Filters can narrow results by band, signal strength, security, or SSID, while access-point distance estimates and OUI-based vendor lookup add context. WiFiAnalyzer supports 2.4 GHz, 5 GHz, and 6 GHz networks, plus HT/VHT channel widths from 40 to 320 MHz where device hardware and software support them.
For reporting or follow-up, the app can export access-point details. That makes it a good fit for a technically minded Android user who needs a free scanner with historical signal views and channel guidance. The trade-off is scope: WiFiAnalyzer is Android-only, and its capabilities depend on what the device supports for bands and channel widths. It is better suited to quick local diagnosis and optimization than to teams needing a multi-platform workflow or deeper site-survey coverage. Choose it for focused, open-source Wi-Fi visibility; consider another tool when broader platform support or more extensive survey work is central.
WiFiAnalyzer pros and cons
- Where it wins
- Free, open-source app with no ads or personal information collection
- Channel ratings, signal graphs, filters, exports, and vendor lookup
- Supports 2.4, 5, and 6 GHz bands where supported
- Where it doesn't
- Android-only, with no iOS, Windows, macOS, or web platform
- Band and channel-width detection depends on device support
- Focused on Wi-Fi analysis rather than broader spectrum workflows
