EMF Meter helps you monitor electromagnetic field levels and Bluetooth exposure from one simple dashboard. Use your iPhone’s magnetometer to track EMF changes in real time, then scan nearby Bluetooth devices to understand signal strength and exposure levels around you. Track your environment at home, work, or while traveling with clear meters, safety zones, and simple exposure insights. Key Features: Real-Time EMF Meter Live electromagnetic field readings in microteslas (μT) Uses your device magnetometer Auto-calibration for local magnetic baseline Total EMF safety meter with clear status levels Bluetooth EMF Exposure Scan nearby Bluetooth devices View Bluetooth signal strength in dBm See Bluetooth exposure percentage Safety levels: SAFE, CAUTION, UNSAFE Detailed nearby device list Safety Levels SAFE: Low exposure CAUTION: Noticeable exposure UNSAFE: Strong exposure DANGER: Very high EMF levels for magnetic field readings Visual EMF Analytics Glowing animated safety background Radial meter with color-coded zones Lowest, average, and highest session readings Simple exposure tables Clean dark and light themes Perfect For: Monitoring EMF levels at home Checking workspaces and desks Comparing rooms and nearby electronics Reviewing nearby Bluetooth signal exposure Health-conscious users who want simple EMF awareness How It Works: EMF Meter uses your iPhone’s built-in magnetometer to measure electromagnetic field variation around your device. For Bluetooth, the app scans nearby wireless sources and estimates exposure from signal strength. Privacy: All readings are processed on your device. No ads, no subscriptions, and no unnecessary tracking. Note: Phone sensors are useful for awareness and comparison, but they are not a replacement for certified scientific or medical equipment. For professional safety testing, use calibrated instruments and consult qualified experts.
