Description
Bug Detector Scanner is a practical privacy inspection tool that helps you check unfamiliar objects and spaces using your phone’s magnetometer together with guided visual inspection.
Use the magnetic scanner to watch changes in the surrounding magnetic field, compare repeated measurements and inspect areas more carefully. The app gives you several ways to view the same magnetometer data, so you are not relying on a single reading or sudden spike.
Whether you are checking a hotel room, bedroom, changing room, restroom, office, vehicle or another private space, Bug Detector Scanner gives you useful tools and simple step-by-step guidance.
MAGNETIC SCANNER: Measure nearby magnetic field strength using the magnetometer built into your phone.
Choose between: • Guided comparison scan • Live signal graph • Field strength meter • X, Y and Z sensor readings
GUIDED COMPARISON SCAN: Magnetic readings can change for many normal reasons, so one high value is not always useful on its own.
The guided scan lets you record a baseline and then measure the same object or area three times. You can compare the average reading, difference, highest value and whether the change appears consistently across your measurements.
This makes it easier to notice repeatable magnetic changes instead of reacting to a single spike.
LIVE SIGNAL GRAPH: Watch magnetic field changes in real time while moving your phone around an object or area.
The graph makes it easier to see peaks, drops and changes over time. You can also view the current field strength and use sound alerts for elevated readings.
FIELD STRENGTH METER: For quick checks, use the field strength meter to see the current magnetic reading in µT.
It is useful when comparing different objects or checking whether the reading changes as you move closer or farther away.
SENSOR VALUES: Want more detail? View the total magnetic-field strength together with the X, Y and Z values reported by your phone’s magnetometer.
69 GUIDED PRIVACY CHECKS: Bug Detector Scanner also includes guided visual inspection checklists with 69 inspection points across 7 different environments.
Checklists include:
• Hotel rooms • Bedrooms • Changing rooms • Restrooms • Vehicles • Offices • Other private spaces
PRIVACY FIELD GUIDE: Not every strong magnetic reading means something suspicious.
The built-in guide explains how to prepare and calibrate your phone, repeat a scan properly, compare readings and recognize common sources of false positives.
The app encourages you to combine magnetometer readings with visual inspection and common sense.
If you are concerned about a possible hidden camera, microphone, tracker or unfamiliar electronic device, magnetic readings may provide an additional clue, but they should not be treated as proof by themselves.
KEY FEATURES: • Magnetic scanner using your phone’s magnetometer • Guided comparison measurements • Live magnetic signal graph • Field strength meter • X, Y and Z sensor readings • Sound alerts • 69 guided inspection points • 7 inspection environments • Saved inspection progress • Calibration guidance • False positive information • Clean and easy to use interface
SCAN SMARTER. INSPECT BETTER.
Bug Detector Scanner is designed to make privacy checks more structured and easier to understand.
Take your time, compare readings, repeat measurements and check ordinary sources before deciding whether something needs a closer look.
IMPORTANT: Bug Detector Scanner relies on the magnetometer sensor available in your phone. Readings and accuracy can vary between devices and may be affected by nearby electronics, magnets, wiring, metal objects and other environmental factors.
Magnetic readings provide supporting information only. They do not identify or confirm the presence of a hidden camera, microphone, tracker, bug or other surveillance device.
Always check ordinary sources first and only inspect places or objects where you have permission to do so.
Recent changes: A major Bug Detector Scanner update is here! • All new modern privacy focused interface • New Guided Comparison Scan for repeatable magnetic checks • New live magnetic signal graph • Improved field strength meter and sensor readings • 69 guided privacy inspection points • New Privacy Field Guide with calibration and false positive tips • Improved scanning experience, performance and stability Enjoy a cleaner, smarter and more reliable privacy inspection experience.
