Original Summary

I’ve been iterating on it while using it in the field for the past several months think it’s decent enough to now share: a receive-only Android app that listens to Wi-Fi access points and Bluetooth LE advertisements the phone already hears, then matches them against a signature list so I can see what’s actually around me in the field. Passive only. It does not connect, probe-inject, deauth, pair, or talk to a server. No account, no ads, no backend. Everything stays on the phone and works offline. What it does: • Live view of nearby Wi-Fi access points and BLE advertisements • Alerts (beep, voice, on-screen) plus a watch list • Filters and saved presets so you’re not staring at noise • Editable signature library (add IDs in-app) • Reports of what was seen • Optional TAK / CoT push if you use ATAK • Decodes Broadcast Remote ID (ASTM F3411 / FAA Part 89) from BLE advertisements when a UAS is transmitting it — aircraft ID, position, and related fields Useful for noticing trackers, cameras, body cams, fleet radios, wearables, and similar advertised sources — then confirming with RSSI and time, not a single ping.
