About

Electronic Device Detector

This app helps you locate lost or hidden electronic devices nearby. It offers two modes: an Infrared Detector for IR-emitting devices like remotes and cameras, and a magnetic sensor mode to find electronics like phones and laptops by analyzing magnetic fields. It also provides tips for staying protected in public.

Electronic Device Detector/Finder app facilitates you to detect any kind of electronics in your vicinity. It is for you if you usually forget where you have put your phone and its on silent. You can easily find lost or hidden devices nearby. App Provides you with 2 modes: 1- Infrared Detector - You can detect Remotes or IR cameras with this mode or any device which emits an IR light. Just close all lights in the place you are and open IR camera mode and scan moving iPhone full 360 degrees, If you see white light or blue light that is invisible to naked eye, then it is infrared light and it could be infrared camera or a remote, well you have to inspect further. Usage: Test with TV remote control light - See TV remote control head with normal eye and press any button, you will not see any light. Then open normal camera or open app and see through the camera - you will see white light. Reason for this is that infrared light is not visible to naked eye but it is visible when seen through a camera. This way you can easily detect IR emitting devices if any. 2. Scan with magnetic sensor – With this mode, app analyse magnetic field around the phone. This feature enables you to find electronic devices like mobile, laptop/pc, cameras etc. If there is a high magnetic filed around, the app will show a warning so you can further investigate. Usage: Move top of your iPhone very close to the object you suspect. It could be screw, flowerpot, shower head, toys or anything that you find suspicious. If app shows a warning when the phone is brought closer to the object, further investigate for camera lens or a mobile phone or any electronic device. It can also be used as hidden camera detector while staying at a hotel room. App also provide you with tip & Tricks so that you can stay protected with some simple tricks or hacks whenever you are in public place. Please rate, comment if you like our app so that we can improve further.

About

Metal Detector 3D Plus

Features
Read full description

Metal Detector enables you to detect metal objects using your iOS devices. You can preview the magnetic field level through a graph and a 3D directional display. Metal Detector measures the magnetic field using the device’s built-in magnetic sensor. The natural magnetic field level (EMF) typically ranges from 25 to 65 µT (microtesla), or 250 mG (milligauss). 1 µT = 10 mG. Any reading above this range may indicate the presence of metal or a change in electromagnetic activity in the area. The magnetic field level increases when metal (such as steel or iron) is near the phone. Magnetic field levels will fluctuate as you move around. You can use this app to find metal objects like electrical wires in walls or iron pipes underground. Metal Detector is most effective at detecting ferromagnetic materials (e.g., iron) and cannot detect non-ferromagnetic materials such as wood, glass, plastic, paper, copper, or aluminum. Features: • Displays device orientation in 3D space using a compass. • 3D magnet icon enlarges as magnetic field strength increases. • Shows maximum detected magnetic field level. • Graph displays magnetic field level over time. • Screenshot functionality with saving to the camera roll. • 3D magnet orientation defaults to magnetic north, like a traditional compass. • Option to reset the maximum magnetic field value. • Sound notification when the maximum magnetic field level is reached. • Option to enable or disable sound notifications. Usage: • Detect metal objects such as electrical wires in walls or buried iron pipes. • Identify objects that may or may not be metal. • Monitor magnetic field level changes in specific areas (e.g., when approaching large metal structures). • Some users believe it may detect paranormal activity (use at your own discretion). • And much more—limited only by your imagination! You can also record your screen for reference: • Go to Settings > Control Center > Customize Controls, then tap the + next to Screen Recording. • Open Control Center. • Tap the Screen Recording icon (circle with a dot inside) to start recording. • The recording begins after a 3-second countdown. • To stop, tap the red status bar or red icon. • The screen recording will be saved in Photos for later viewing. Note: Magnetic field readings may be affected by nearby electronic equipment (TVs, computers, microwaves) due to electromagnetic interference. Thank you for your support!
