Check out the areas where you work (desk, meeting rooms), where you sleep (bed), where you relax (couch, living room) and find the levels of EMF you are exposed to. Also use the app to measure the fields emitted by your appliances (computer, fridge, speaker, phone...). PROFESSIONAL MAGNETIC FIELD ANALYZER & GAUSS METER: Discover the invisible magnetic world around you. Using your device’s internal magnetometer, the app provides a comprehensive look at the electromagnetic fields (ELF) generated by electronic devices, wiring, and ferromagnetic materials. NEW PROFESSIONAL FEATURES: - 3-Axis Vector Analysis: Real-time $x, y,$ and $z$ coordinate tracking for precise field directionality. - Interactive History Graphs: Visualize time evolution with high-resolution charts that track spikes and trends. - Clean Signal Mode (LPF): Toggle an advanced Low-Pass Filter to stabilize readings and remove sensor jitter for professional-grade clarity - Save & Export Logs: Record your sessions and export data for further analysis in external software. VERSATILE USE CASES: Electronics Inspection: Measure the magnetic footprint of computers, speakers, and home appliances. Metal Detection: Locate ferromagnetic objects like iron pipes or steel studs behind walls. Interference Calibration: Find the "quietest" zones for sensitive electronic equipment or audio setups. USER EXPECTATIONS & DISCLOSURE: This app is designed as a sophisticated utility for detecting Magnetic Fields (ELF). What it detects: Magnetic flux from magnets, ferrous metals, and the low-frequency electromagnetic fields emitted by electronic components, power supplies, and speakers. What it does NOT detect: This app is not a radio frequency (RF) scanner. It cannot detect Wi-Fi signals, Bluetooth, 5G cellular radiation, or microwave leakage.
