Turn your iPhone, iPad, or Apple Watch into a powerful EMF Detector and magnetic field meter. Track magnetic fields near you. A warning beep will be activated to warn you. Measure nearby magnetic fields in real time using your device’s built-in magnetometer. Monitor changes, receive alerts when stronger readings are detected, and view measurements in nanoTesla (nT) or milligauss (mG). MAP YOUR ROOM AND DISCOVER MAGNETIC HOTSPOTS Explore your surroundings in a completely new way with Room Mapping. Simply walk around the room while the app records magnetic field readings and builds a visual map showing where the strongest areas are located. Your EMF Detector can help you quickly identify magnetic hotspots that might otherwise go unnoticed. Room Mapping can be especially useful in bedrooms, home offices, or other places where you spend many hours. Walk around the room and check whether stronger readings appear near your bed, desk, walls, electrical installations, appliances, speakers, chargers, or other nearby objects. The resulting heatmap makes it easy to understand which parts of the room show higher or lower magnetic field activity, helping you investigate the source and decide whether you want to reposition nearby objects or devices. MONITOR MAGNETIC FIELDS IN REAL TIME Watch magnetic field levels change instantly as you move your device around your environment. The EMF Detector provides visual gauges, graphs, alerts, and historical readings so you can compare different locations and observe how magnetic field levels change over time. Save important readings with their date and time and review them later whenever you need. FEATURES • Real-time magnetic field detection • Room Mapping with visual magnetic heatmaps • Identify stronger magnetic hotspots around a room • Interactive EMF gauges and graphs • Measurements in nanoTesla (nT) and milligauss (mG) • Alerts when higher magnetic field levels are detected • Save readings with date and time • Review previous measurements and records • Multiple meter styles and interface colors • Monitor readings from iPhone, iPad, and Apple Watch • Designed for quick comparisons between different locations Use the EMF Detector to explore magnetic activity around electrical installations, appliances, speakers, magnets, chargers, metal objects, and other nearby sources that may influence your device’s magnetometer. Measurements depend on the magnetometer available in your device and can vary depending on hardware, device orientation, nearby magnetic materials, and environmental conditions. This app is intended as an informational measurement tool and is not a substitute for professional EMF measurement equipment.
