Hidden Devices Detector is a utility tool for Android devices developed by iffiapps. This app serves as a bugs detector, allowing users to search for mini cameras and detect hidden cameras and microphones in various private locations like homes, hotels, and restaurants. It helps users identify spy hidden devices such as cameras and microphones that are covertly placed for surveillance. The app utilizes the phone's magnetic field sensor to detect hidden cameras and alert users, providing a layer of security against being recorded or monitored without consent.

Hidden Devices Detector offers features like background video recording, enabling users to record videos while using other applications on their phones. The app employs two methods for detecting hidden cameras: the Radiation Meter, which detects high magnetic fields and alerts users, and the Infrared Light Detector, which reveals invisible infrared light that many hidden cameras emit. It's important to note that the app does not access personal data and requires manual confirmation of hidden devices after detecting high radiation levels.
