Description
Lens & Magnet Tools provides on-device utilities that can help you perform manual privacy checks in unfamiliar spaces. It includes a Reflection Helper for observing potential lens-like highlights and a Magnetic Field Meter for viewing nearby magnetic field changes. Everything runs on your iPhone—no accounts, no tracking, and no data leaves your device.
Why use it?
When you’re in a hotel, rental, changing room, meeting room, or office, these tools can support your manual inspection. The app does not detect or identify hidden devices; it simply helps you notice signals that may merit a closer look.
Two On-Device Tools
1) Reflection Helper (Camera/Lens Aid)
Uses light to help you observe specular highlights that might resemble small lenses.
Adjustable sensitivity to reduce false positives.
Step-by-step guidance on where and how to look.
Works entirely on-device.
2) Magnetic Field Meter (Magnetometer-Based)
Live readout and graph of magnetic field variations near objects.
Optional haptic/sound alerts when a user-defined threshold is exceeded.
Useful for inspecting mirrors, smoke detectors, alarm clocks, picture frames, vents, and similar housings.
Uses your iPhone’s built-in sensors; no extra hardware.
Key Features:
Reflection Helper for possible lens-like highlights
Magnetic Field Meter with real-time graph, peak hold, and threshold alerts
Quick Room Sweep checklist to encourage safer habits
Practical tips: where to look, how to angle light, recommended distances
100% on-device; no sign-up, no cloud, no background data collection
How to Use:
Calibrate (magnetometer): Move your iPhone in a small figure-8 to improve readings.
Reflection Helper: Dim the lights slightly, then scan surfaces slowly. Look for pinpoint, persistent highlights that may deserve closer inspection.
Magnetic Field Meter: Hold the device ~2–5 cm from objects (mirrors, adapters, clocks, vents). Rising values can indicate magnetic materials inside.
Verify & Inspect: If something stands out, perform a careful manual check. Use both tools together for stronger confidence.
Where to Check:
Hotels & rentals (bedroom, bathroom, living areas)
Meeting rooms & offices (projectors, clocks, smoke detectors)
Changing rooms & public restrooms (mirrors, hooks, shelves)
Rental cars & shared workspaces (dash areas, vents)
Privacy First:
100% on-device operation
No personal data collected, sold, or shared
Important Notes:
This app assists with manual checks; it does not detect or identify hidden devices.
No detection is guaranteed. Results depend on lighting, distance, materials, and ambient interference.
The Magnetic Field Meter reflects field variations; many ordinary items can influence readings.
