Start a sweep by tapping the radar itself. Find AirTag, Tile and SmartTag trackers that travel with you, plus magnetic and lens-glint checks for hotel rooms.
A four-mode privacy sweep for hotel rooms, rentals, changing rooms and your own bag.
ITEM TRACKER DETECTION
• Identifies nearby AirTag, Tile, SmartTag and Chipolo trackers by their Bluetooth signature
• Follow detection — the app remembers what it has seen, so it can tell you when the same tracker keeps reappearing across separate sweeps in different places. That pattern, not a single sighting, is what matters
• Distance band by signal strength, so you can walk toward it
• Your own paired devices are filtered out, and anything found is labelled as a lead to check, never as proof
CAMERA AND ROOM SWEEP
• Lens reflection check — a guided walkthrough that uses the camera to help you spot the glint of a lens in vents, smoke detectors and mirrors
• Bluetooth device scan — counts nearby signals and flags unnamed devices sitting close by
• Magnetic anomaly — takes a two-second baseline when the scan starts, then alerts on field spikes as you sweep past fittings
ROOM-BY-ROOM SWEEP LIST
Work through bedroom, bathroom, living room and office, marking each as swept. Progress saves itself, so an interrupted sweep can be picked up later.
RECORDS
• Every scan is saved with a 7-day trend and a plain-language summary
• Note and favourite any scan; compare two saved scans side by side
• Export as CSV or share a single result
• Watchlist — mark a device as suspicious and the app tells you when it shows up again
WHAT THIS APP CAN AND CANNOT DO
iPhone cameras have infrared-cut filters, so this app does not see infrared. The lens check works on reflection: a lens returns a distinctive glint when light hits it straight on. Bluetooth gives you presence and rough distance, never direction. Magnetic detection depends on starting somewhere clean and sweeping slowly. No phone app can guarantee a room is clear — use all four checks together, and treat every hit as something to look at rather than a verdict.
If you believe you are being followed or watched, contact local authorities. This app is a tool for looking, not evidence.

Tap the radar on the Detect tab to start a scan — no need to hunt for the small button. The scan button now stands out while idle, a short tap vibration confirms each start and stop (follows your Vibration switch), and the tab bar uses cleaner line icons.
