Best open-source Wi-Fi analyzer — ad-free, privacy-focused, and super useful! Latest Jan 2026 update (v3.2.2) adds Android 16 support, smoother scalable graphs, translations, OUI DB refresh, and bug fixes. Real-time signal graphs, channel ratings, 2.4/5/6 GHz bands, AP distance estimates, vendor lookup, themes, filters — all help spot crowded channels and fix dead spots fast. No tracking, minimal permissions. Actively maintained gem. Essential for optimizing home/office Wi-Fi. Thank you devs! 🚀

It's a pretty decent App What I love most about it is the fact that it's open source. I feel more Android apps need to be open source :)

It's pretty good, but for some reason it crashes whenever I switch to view 5GHz network making the tool useless. This never used to occur.
★☆☆☆☆Owl Hollow· Jun 10, 2026
Good, but slow to update. It also keeps asking to report back my GPS location so all the SSIDs can be sent back. Who is all this Wi-Fi info being sold to? That data is obtained deceptively. To show a signal strength, you monitor RF, not send a copy of what I can hear at my address. It also stays running and reports SSIDs heard while I am out.

Without location this app cant do anything while others can at least tell me about my own connection if u press ok. The app shutdown so no point in using it shames too I trust open source stuff
