NetInspector

Android network analyzer - scan the Wi-Fi environment, discover hosts on your local network, and run diagnostic tools. Runs entirely on-device: no root, no NDK, no accounts, no telemetry, no analytics.

Features Wi-Fi analysis - visible access points with band, channel, width, security and standard; channel occupancy graph; a recommendation engine for picking a clear channel. LAN discovery - enumerates hosts on the connected subnet and identifies them via mDNS, SSDP and vendor OUI lookup, with a confidence label on each guess. Diagnostics - ping, traceroute, reverse DNS, and port scanning, launchable directly from a discovered host's detail screen. History & export - scan and diagnostic runs are persisted locally and can be exported to CSV/JSON. Adaptive UI - built for phones, tablets and foldables from the start: window size classes, fold-aware layout, and UI state preserved across rotation.
