FAQ
What is Argus?
Argus is a counter-surveillance app that uses your iPhone's sensors to help you detect hidden cameras, listening devices, and trackers. It provides a structured protocol for sweeping rooms, mirroring professional techniques.
How does Argus detect hidden cameras?
Argus uses an Optical Lens Scan to flag reflective glints from camera lenses and an Infrared Detector to surface invisible IR light sources from night-vision cameras.
Can Argus find Bluetooth trackers?
Yes, Argus includes a Bluetooth RF Sweep that discovers BLE transmitters in the 2.4 GHz band, which includes common Bluetooth item trackers and BLE bugs.
Does Argus work offline?
Yes, Argus is designed with privacy by design and works fully offline. It does not require an account, cloud sync, or telemetry, making it useful even in situations where you don't want to broadcast your activity.
What kind of reports does Argus generate?
Each sweep produces a shareable PDF report called a Sweep Dossier. This report includes a safety score, flagged devices, timestamps, and findings, all recorded live on-device.
Are there different modes or presets in Argus?
Argus offers six guided room presets: Hotel, Airbnb / Vrbo, Office, Bathroom, Changing Room, and General. Each preset guides you step-by-step on where to point your phone and what to look for.
What is the Threat Map feature in Argus?
The Threat Map is a unique feature that geotags each sweep and pins it on a MapKit view, color-coded by threat level. This allows users to browse past locations they've checked, which is useful for frequent travelers and hosts.
Is Argus suitable for frequent travelers?
Absolutely. Argus is designed for travelers to quickly check hotel rooms before unpacking. Its guided presets and quick sweep protocol make it efficient for on-the-go security checks.
