Fieldwatch listens to Wi-Fi and BLE and identifies radios around you from a signature catalog you manage in-app (tags, body-cams, drones, vehicle APs, etc.). Set alerts when a watched signature or MAC is heard. Work a sit to compare the same area or drive over time. Track radios moving with you and generate reports from that data.
Here is what’s new since my last update: Fieldwatch 1.1.8 is on GitHub. Signature catalog is now 75.
Name Wi-Fi the way you already name BLE: fleet cars, mesh, guest APs, and the locally administered BSSIDs that used to hide the pencil. If your local fire trucks trip the Compex signature, edit the Advertised name to “Fire Truck Station 51.” Works on any radio Fieldwatch treats as a non-rotating MAC. Manage named radios under Settings.
The Detail page now describes the radio from the signature match. A Raven on Wi-Fi Direct reads as a gunshot sensor.
New signatures for privacy awareness: Digital Ally and other body/in-car cameras, wearable recorders, camera glasses, and roadside names Fieldwatch can hear.
Since 1.1.4 you can refresh the stock catalog with Update stock catalog from GitHub under Settings.
Add observer notes to a radio: a short caption you write. It shows on Detail, as a chip on the Live list, and in every report.
Walk the ground, then see the walk. Path is a north-up trace of this phone for the sit you named. Red dots are Extra attention. Blue dots are radios you named. Dots mark where you were when you heard them — not a pin on the other radio. Works offline in Airplane mode. The same trace prints on Debrief and Compare PDFs.
Two rooms, two days, one question: what was only here? Compare sits is presence only — only in this window, only in the other, or in both. Kind plus MAC. Text, PDF, and a paste-ready AI addendum. Not a second inventory for a chatbot to reprint.
Export logs or sits as CSV, JSON Lines, GPX, KML, or WiGLE CSV.
Plus a lot of cleanup. If you haven’t pulled the latest APK in a while, this one is worth it. The user manual is updated to match.
