Worried someone might be spying on you? Instantly scan for hidden cameras, GPS trackers, and spy bugs using your phone. Spy Detector: EMF Scanner helps you protect your privacy with real-time magnetic field detection and instant alerts. HOW IT WORKS Your phone already has a magnetometer sensor built in — the same one used by compasses. Spy Detector transforms that sensor into a powerful EMF scanner, letting you identify unusual magnetic activity around you. Such magnetic spikes may occur near hidden electronic devices, metal objects, or power sources. FEATURES - Smart EMF scanner: Uses your device’s magnetometer to measure real-time magnetic field strength in microteslas (µT). - Hidden device alerts: Set sensitivity levels and get instant audio or vibration alerts when magnetic readings suddenly spike. - Live visual graph: Watch real-time waveforms of detected signals as you move your phone around. - Customizable sensitivity: Adjust thresholds for different environments (home, car, office, hotel). - 3-axis readouts: View detailed X, Y, Z sensor values for precise analysis. - Data history: Quickly review recent magnetic field changes to spot patterns. - Clean, discreet interface: Dark “matrix-style” visuals that look sleek and reduce glare in low light. - Offline & private: No internet, no tracking. All processing happens locally on your device. HOW TO USE 1. Open the app, tap on "SCAN" to start scanning. 2. Move your phone slowly around suspicious areas (mirrors, walls, smoke detectors, switches). 3. Watch for magnetic spikes on the live graph or listen for alerts. 4. Adjust sensitivity if needed to reduce false signals. 5. Use vibration mode for silent, discreet scanning. PERFECT FOR - Travelers checking hotel rooms or rentals - Anyone concerned about hidden recording devices - Security-minded professionals or journalists - Students and hobbyists exploring EMF fields - Everyday users who value privacy and peace of mind Protect your privacy today. Download Spy Detector: EMF Scanner and take control of your personal space. IMPORTANT NOTE Spy Detector: EMF Scanner uses your device’s built-in magnetometer to detect changes in magnetic fields. While strong spikes may indicate nearby electronic components, magnets, or metal structures, the app cannot guarantee detection of hidden cameras or GPS trackers in every case. Use it as a first-line privacy tool and combine it with visual inspection for best results. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
