Your Privacy Is Our Priority
Hidden Devices Detector is not just a spy camera finder. It’s an all-in-one solution for anyone who wants to take control of their privacy. With the growing risk of unauthorized surveillance, having a hidden devices finder app is a smart way to stay safe.

Anyone who values digital privacy and personal space
How It Works:
šŸ”¹ Magnetic Sensor Mode:
Move your phone slowly near suspicious objects. If there is a hidden electronic device, the magnetic field value will increase, and the app will alert you with a beep.
šŸ”¹ Infrared Camera Mode:
Turn off the lights and scan the area using your phone camera. Infrared light appears as a white or glowing dot on the screen. If you see a dot, check the object more closely for hidden lenses.
Important Notes:
The radiation detection feature only works on devices with a magnetic sensor. If your phone does not have one, please use the infrared detection mode instead.
Infrared detection depends on your phone's camera quality and hardware. It may not be supported on older devices.
This app does not access your personal data, making it 100% safe and secure.
Tips for Better Results:
Always scan in dark environments when using the infrared mode.
Move your device slowly and steadily for accurate detection.
Cross-check multiple spots in the same room for the best results.
Use the app regularly when traveling or entering new environments.

Can't stand options for ads. You can't skip them or minimize them. It shows the option bar to "skip ads" but when you click on it, it literally buzzes you like you've done something wrong. These ads take up half of your phones screen and thus are visually obnoxious. Not digging the ads at all. If they were like other site "manageable" then I would say no more. Otherwise it core functions operate well and the site is easy to navigate.

Honestly I think this is the best app for finding devices but it could use a lot of work in a lot more professionalism. There's even grammar issues on the notes answers and questions. With an app I don't think that is very professional and should be corrected if you're going to get reviews. However I have found that this one works the best when it comes to finding any radio signals or hidden devices of any kind. Just needs a little tweaking and it'll be a five star!

I was staying at a hotel and a friend told me about this app. So I downloaded and tried it and in our hotel room we didn't find anything but in my oldest sisters room it lit up. We got her money back and will not be staying at that hotel anymore. I was in complete shock!
