Hidden Devices Detector

Hidden Devices Detector combines magnetic field readings and manual camera lens inspection in one simple app. View changes in your surroundings with your phone’s magnetic sensor, or inspect visible objects using camera zoom and flashlight.

The app provides inspection aids. Magnetic readings and camera reflections cannot confirm the presence of a hidden camera or other hidden device.

Magnetic field readings

Use your phone’s magnetometer to view magnetic field strength in microteslas (µT). Choose from four reading views:

• Digital Reading: See a large numeric reading, magnetic field status, and X, Y, and Z sensor values.

• Magnetic Graph: Follow magnetic field changes over the last 60 seconds.

• Sensor View: Read a clear µT gauge alongside the three sensor axes.

• Magnetic Meter: View live magnetic readings on a marked gauge.

Check the session maximum, reset your session, and enable optional sound alerts for elevated readings. All four views use the same magnetic sensor, giving you different ways to display its measurements.

Manual Lens Inspection

Take a closer look at objects with the rear-camera preview:

• Adjust camera zoom within your phone’s supported range.

• Turn the flashlight on or off where available.

• Tap the preview to focus on supported devices.

• Read built-in guidance about reflections and inspection limitations.

Lens Inspection is a manual visual tool. It does not automatically identify hidden cameras or classify objects.

Simple controls and local processing

Hidden Devices Detector offers a clear dashboard, readable measurements, and built-in help. Magnetic readings and camera preview frames are processed on your device. The app does not save or upload camera images.

Camera permission is requested only when you choose to enable Lens Inspection. Magnetic readings and camera inspection work without an internet connection; advertising and online privacy links may use internet access.

Device requirements and limitations

Magnetic tools require a working magnetic field sensor. Camera zoom, flashlight, and focus capabilities depend on your phone.

Magnets, speakers, nearby metal, and other everyday objects can affect magnetic readings. A high reading does not prove a hidden device is present, and a low reading does not prove an area is free of hidden devices.

Hidden devices detector app does not scan radio frequencies, pinpoint tracking devices, or guarantee detection of cameras, microphones, or other electronics. Use its readings and visual tools to support careful manual inspection.
