Hidden Device Finder, Detector

Hidden Device Finder is a lightweight privacy tool that helps you detect hidden cameras, microphones, trackers and other spy devices using your phone’s magnetic sensors. The app offers an easy-to-use scanner and real-time alerts (vibration or sound) as you sweep suspicious areas in hotels, offices, rental properties or at home. Key features include a bug/camera finder, microphone locator, tracker detector and a general bugs scanner to help maintain your personal privacy.

How it works: open the app and slowly move your phone around the area you want to check — around furniture, ceilings, walls and power outlets. The app reads magnetic field disturbances and notifies you when a potential electronic device is nearby. Use it before staying in unfamiliar places or whenever you suspect unauthorized surveillance to quickly locate and disable hidden devices.
