 "description": "Privacy starts with awareness.\n\nA hotel room. A rental. A rideshare. A space you share. Spectra by Arc Signal brings Bluetooth activity, supported local-network services and close-range magnetic clues together—so a privacy check can be part of settling in.\n\nAn Experimental Apple Watch companion is included: collect Bluetooth clues without your iPhone nearby, then review them on iPhone later.\n\nRecognize nearby Bluetooth activity\n\nGet a 30-second Bluetooth snapshot without pairing. Names and broadcast clues suggest possible device families or models—from headphones and speakers to supported smart glasses and wearables. Focused checks narrow your review. Follow supported findings with fresh live signal-strength readings—not distance or direction.\n\nLearn from your local network\n\nExplore supported services from speakers, streaming players and smart-home products on your joined network. Useful clues, even without an exact model—not a scan of every nearby Wi-Fi radio or proof of a device's physical location.\n\nLook for clues to concealed electronics\n\nSome electronic components produce magnetic fields your iPhone's magnetometer may detect at close range—even without a recognizable wireless broadcast. In Area Sweep, repeatable changes may warrant a closer physical look. Practice with familiar objects.\n\nOrdinary magnets, magnetic metal and phone accessories can affect readings. A magnetic change cannot identify a camera or microphone or prove recording. Some electronics produce little detectable change; a quiet reading does not rule out a device.\n\nCollect on Watch. Review on iPhone.\n\nCapture a 30-second Bluetooth sweep on Apple Watch. Keep Spectra active and the display fully awake; this is not background scanning. Save up to five local captures, then reconnect and open Spectra on your paired iPhone to review possible matches. Unsent captures are kept; full storage can block a sweep. Apple Watch is optional.\n\nNotice what changes\n\nMonitor radio activity against a baseline while your iPhone stays in one place. Review changes in context—not proof that a device arrived or left.\n\nYour observations. Your control.\n\nScan interpretation runs on your iPhone. No account, in-app ads, subscription or in-app purchase. Scans aren't automatically sent to Arc Signal or an external AI service; sharing is your choice.\n\nExplore a finding with optional on-device Apple Intelligence, or review a prepared prompt and evidence to share or copy to an external AI app. Recipient policies apply; AI can make mistakes.\n\nKeep what matters\n\nSave searchable sessions and notes, revisit magnetic graphs, and export or import supported archives after review. Archived results are historical—not fresh measurements. Saved iPhone sessions aren't automatically removed.\n\nBuilt to keep getting better\n\nCatalog and detection-engine improvements are included in App Store updates at no additional charge. Recheck eligible saved evidence with newer recognition—not new measurements. Originals stay unchanged; better matches aren't guaranteed.\n\nKnow the limits\n\nSpectra cannot prove a device is hidden, recording or malicious. Names and matches don't authenticate identity. Silent, wired, shielded or unrecognizable devices may be missed; no findings is not an all-clear.\n\nChecks need Spectra open and active. Results depend on signals, permissions, hardware and measurement quality. Inspect only places you are allowed to examine; respect privacy and facility rules.\n\nRequires iPhone with iOS 27 or later. The optional Watch companion requires watchOS 27 or later and a paired supported iPhone. On-device AI needs compatible hardware and enabled, available Apple Intelligence.\n\nDeveloped by Arc Signal LLC.",
