Read full description

Measure magnetic fields with real sensor data. Real EMF Detector turns your iPhone into a precision magnetometer using the built-in calibrated magnetic field sensor to detect and measure DC magnetic fields around you. CALIBRATED SENSOR TECHNOLOGY - Uses Core Motion calibrated magnetic field data that removes device self-interference - X, Y, Z axis breakdown showing directional field components - Total field magnitude in microtesla with continuous updates - More accurate than raw magnetometer apps that include phone hardware noise REAL-TIME DETECTOR - Large circular gauge with smooth animated needle - Color-coded safety levels: Background, Normal, Elevated, Strong, Very Strong - Instant response as you move through your environment - Configurable threshold alerts with haptic feedback LIVE GRAPH - Real-time scrolling chart built with Swift Charts - Track magnetic field changes over time as you scan - Pinch to zoom and scroll through recorded data - X, Y, Z axis overlay for detailed field analysis STUD & METAL SCANNER - Detect metal objects, pipes, and wiring behind walls - Find studs by scanning for nail and screw patterns - Audio and haptic feedback as field strength changes - Sensitivity adjustment for different scanning needs SESSION HISTORY - Record complete measurement sessions with one tap - Review past sessions with full statistics and timeline - Export session data as CSV for further analysis - Stored locally with SwiftData for fast access LEARN & UNDERSTAND - Educational guide to magnetic fields and EMF science - Understand what your readings mean in everyday context - Reference chart comparing common magnetic field sources - Safety information based on published exposure guidelines COMMON USES - Home inspection: check appliances, wiring, and electrical panels - Stud finding: locate metal fasteners behind drywall - Education: learn about magnetism and electromagnetic fields - Hobby and exploration: investigate unusual magnetic sources - Workplace assessment: identify strong field areas HONEST ABOUT LIMITATIONS Real EMF Detector measures DC magnetic fields using the iPhone magnetometer. It cannot detect RF signals, Wi-Fi, cellular (5G/4G), AC electromagnetic fields, or electric fields. For those measurements, specialized equipment is required. What it does measure, it measures well -- with calibrated data that most competing apps lack. Built with SwiftUI, Swift Charts, and Core Motion. No ads, no data collection.

Four new tools join the meter in 1.1: Radar, Metal Finder, Presence Meter and SLS-Style Camera. Every number on screen comes from your iPhone's own sensors. The magnetometer reading is real. What it means is up to you. THE METER: EMF Detector reads your iPhone's magnetometer and shows the live magnetic field in ยตT or mG. Each start calibrates a baseline for the room and tells you how steady it was. Readings are classed Calm, Weak, Potential, High or Extreme. - Meter | Graph switch; live 30-second graph with X, Y and Z toggles - Sensitivity presets, haptic and beep feedback - Record Mode: a clean full-screen view for filming - Siri and Spotlight shortcut into the meter THE TOOLS TAB (all four free to open): - Radar: a live compass radar driven by the magnetometer. When the field reaches Potential or above, a blip appears in the direction your iPhone faces. - Metal Finder: shows how far the field moves from its baseline, with a threshold, beep and vibration. It responds to magnets and magnetic metals such as iron and steel, not to gold or aluminium. - Presence Meter: shows how much your iPhone itself moves, from its accelerometer. Set it down and it reacts to bumps and vibration. - SLS-Style Camera: a live rear-camera view. Apple's Vision framework looks for human body shapes on your iPhone and draws a stick figure only where it finds one. People, mannequins, photos and TVs can show figures; an empty room shows none. Your live EMF reading stays on screen. RECORDING: Tap Record and walk the space; each spike is marked as it happens. Tap Stop for the timeline, spikes, baseline and peaks. Compare any two sessions side by side. FREE AND PRO: Free: the meter, graph, Record Mode, recording (3 most recent sessions kept), session detail, compare and all four tools. Pro adds: no ads; unlimited history; CSV export; radar skins (colour themes: Thermal, Night Vision, Vintage); Presence Meter recording, sensitivity and sound alert; SLS-Style Camera extras: Depth (LiDAR) on iPhones with LiDAR, a night-vision-style filter and photo capture. Without Pro, a rewarded ad unlocks one session's export while its screen stays open, or a time-limited trial of the Pro tool extras. The trial does not remove ads or unlock history or export. SUBSCRIPTIONS: EMF Detector Pro: Weekly $2.99 (3-day free trial), Monthly $4.99 (3-day free trial), or Lifetime $24.99, a one-time purchase. Prices are in US dollars; the App Store shows your local price. Free trials are for eligible new subscribers. Payment is charged to your Apple Account. Subscriptions renew automatically until cancelled. To cancel: Settings > your name > Subscriptions > EMF Detector Pro > Cancel Subscription. To avoid renewal after a free trial, cancel at least 24 hours before it ends. ADS: Free users see Google AdMob ads: a native card labelled "Ad" on the meter and tool screens, and occasional full-screen ads after you stop a recording, when you leave a tool, and when you go back from a saved session, a comparison or the instructions. No ads appear on their own in Record Mode or while recording. ENTERTAINMENT NOTICE: The magnetometer reading is real. What it means is up to you. Magnetic fields change near wiring, appliances, magnets, metal and other phones, and this app cannot tell those apart from anything else. It is made for paranormal-style entertainment and does not claim that a change in the field means a ghost is present. PRIVACY: No account. The camera works only in the SLS-Style Camera tool; images are processed on your iPhone and nothing is stored or sent unless you share or save a photo. Sharing usage data (Google Analytics for Firebase) is your choice, changeable in Settings. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://ashaquavision.com/privacy-policy/emf-detector-ios/ iPhone only. Requires a device with a magnetometer.
