Definitely try my app Fieldwatch if you want to know what devices are actually being used around you. It is an Android app that listens to the Wi-Fi and Bluetooth your phone already hears, matches them against a signature database, and flags what matters. Useful for: • Lost or hidden tracker tags • Devices moving with you (including a tag under a car seat) • Card-skimmer class radios • Flock-style cameras still talking BLE or Wi-Fi • Axon-class body cams • Fleet / public-safety radios • Meta glasses and wearables • Flipper, Pineapple, Marauder • Known vehicles with a stable keyless / TPMS / infotainment address • Drones — if Remote ID is on BLE, it decodes position and aircraft info Beep, voice, and on-screen alerts. Watch list. Night mode. Multiple views, sorts, and saved filter presets. And it’s free: https://t.co/ZwG3UbiHpg
