Stand next to a suspect device, capture the raw air, and the app tells you its signature — then log it (photo + GPS) to your encrypted database and export it for DeFlock. Captures need the USB cable, or an SD card in the board.
1 · Investigate an environment
Logs every WiFi frame and BLE advert on all channels. Longer is better — one full sweep takes a few minutes, so give it time to catch a rare transmitter. The detector's beeper is paused while capturing.

Survey log (0)
Every survey on this phone, newest first. Tap one to analyze it again or log a photo against it. Photos and locations are encrypted behind your PIN.
Export decrypts everything to Documents/signalsweep-evidence-<date>/ — photos, cameras.csv, cameras.osm and the raw captures. Grab it with the Files app, a USB file transfer, or adb pull /sdcard/Documents/. That folder is plaintext: delete it once it's off the phone.
Saved pins
Places you confirmed, one GPS fix each, encrypted behind your PIN. Turn the prompt on with Record on the Sweep screen, or in Settings.
Erase
One store, one key: this deletes every pin, every logged find and its photos. It cannot be undone, and a forgotten PIN is the same thing — by design.
Alerts
How the board gets your attention, and what for. Saved on the board.
How it alerts
Sound
Lights
One lights a single LED in the alert’s colour. Off stays dark, even during an alert.
Alert for
Sound and lights are both off, so nothing will alert.
A category switched off is still detected and listed; it just stays quiet.
Theme
Ignored devices (0/16)
Your own gear. Still detected and listed; never beeps, flashes, counts or logs. Kept on the board, so it holds on a battery with no phone.
Recording
Record on the Sweep screen brackets an outing: it turns the board’s log on, and asks to pin what matches. These are the same switches on their own, plus the housekeeping.
Log alerts on the board
Off. The board keeps no record of what it beeped at.
Ask to pin matches on the map
Pinning these without asking — tap to ask again:
Not asking about these any more — tap to start again:
Each matched device asks before saving one GPS fix. Detecting never needs the PIN. Stopping a recording turns this back off unless you set it here.

Radios
Both come back on after a power cycle — pausing one is for this session only. The device is the authority here: these read back what it reported.

Detection
Attack‑gear detection flags nearby hacking tools — a Pwnagotchi, a Flipper Zero, an OUI‑Spy or a WiFi Pineapple’s control network, plus deauth bursts, karma/PineAP access points and BLE popup‑spam floods. Off by default: it is attack‑adjacent and some of it trips in busy places. These devices list and beep under All only, never the camera tab. Persisted on the board.
Attack‑gear detection
Emissions
Receive-only stops the device announcing itself — no advertising, no connection. It keeps scanning and keeps beeping; this is not the buzzer mute. Over Bluetooth this connection will drop — tap the BOOT button on the device to bring it back for two minutes. Over a USB cable nothing drops: only the radio goes quiet, and you can turn it back on here.
Receive‑only
Device identity
The app finds the device by its service UUID, so renaming it never breaks discovery. Useful for telling two boards apart — or for not announcing what it is.

Signatures
Everything the board is looking for right now. The rules are read back from the board itself, on demand — the reply is several KB, so it is never sent on connect.
Always on
Built into the firmware. These need no rule and cannot be edited.
