EMF Detector reads your phone's magnetometer and shows the magnetic field around you in µT or mG: on a live gauge, as separate X, Y and Z axes, and over the last 24 hours. START IN ONE TAP Tap the gauge, or the green START button under it. The app first separates the phone's own magnetism from the field around you. While it says "Calibrating…", turn the phone slowly in a figure-8 for a few seconds; the live reading then appears and stays steadier while you tilt the phone. A short vibration confirms every start and stop. TWO WAYS TO MEASURE • Standard: a radial gauge with plain-language levels from "No EMF detected" upward. In Settings you can switch it to a Safety view that labels a reading as background, weak field, wiring detected or live wire (an estimate from field strength, not proof of a wire) and sets it against ICNIRP reference levels for the general public or for workers. • Paranormal: records a quiet baseline first, then rates each spike against it on a five-step scale and marks it on a session timeline. FIND THE SOURCE The Source tab turns the reading into a warmer / colder hunt. Move the phone slowly around the room; the indicator shows whether the reading is rising or falling, and the X/Y/Z bars show the sensor's value on each axis. KEEP A RECORD • Measurement sessions are saved with their minimum, average and maximum • A 7-day trend with insights, such as how a reading compares with your usual level • Notes and favorites for each reading, plus a side-by-side compare view • CSV export of your history, and share-as-image for the current reading • A 24-hour exposure chart on the main screen • Peak hold, and "Zero here" to re-learn the baseline in a new spot • Calibration offset, µT or mG units, and a choice of reference levels TIPS FOR A GOOD READING 1. Start away from speakers, magnetic cases and car mounts, and do the figure-8 until the number appears. 2. Hold the phone flat and sweep slowly, a few centimetres from the wall or appliance. 3. Watch for a rise against your starting level rather than one absolute number. 4. Tap "Zero here" when you move to a new room so the baseline is re-learned there. FOR GHOST-HUNTING NIGHTS Spirit Box turns the live field into pulses, vibration and spoken words. It is entertainment: field spikes come from wiring, motors, magnets and the phone itself, and no spirits are detected. A Halloween theme can be switched on in Settings. HONEST TECH NOTE A phone magnetometer measures static and slowly changing magnetic fields: steel, magnets, motors, transformers and wiring under load. It samples about ten times a second, so it cannot measure 50/60 Hz mains fields accurately, and it cannot detect radio frequency, Wi-Fi, 5G or radiation. It is not a certified safety instrument; use it to explore and compare readings around your home. Made for curious people comparing readings around appliances and from room to room, and for paranormal investigators.

You can't see it. But it's there. The magnetic field humming off the wiring in your wall. The strange spike beside the crib. That cold, prickling sense at 2 a.m. that something in this room is… off. Your iPhone has carried a real sensor for it all along — its magnetometer. Veil is the app that finally lets it speak. HONEST IN A SEA OF FAKES Most "EMF" and "radiation detector" apps are theater. Your phone has no antenna for Wi-Fi or 5G, so those dramatic "radiation" numbers are invented. Veil measures the one thing your phone genuinely can: real magnetic fields, in microtesla — the same quantity the classic EMF meters read. Everything you see is real. PROFESSIONAL — FOR WHEN YOU NEED TO KNOW The outlet behind the headboard. The nursery beside the breaker panel. Sweep slowly and watch the reading rise and fall against Earth's natural range. The Guided Home Check walks you room by room and hands you a clean report to keep — trade the late-night wondering for an answer. HOTEL & RENTAL CAMERA SWEEP (PRO) Checking into a hotel or Airbnb? Veil guides you spot by spot — smoke detector, TV, alarm clock, outlets, vents, mirror — and flags the magnetic and metal traces electronics leave behind. A clear-eyed sweep for the hidden cameras you can't see. (Inspect by eye too: a magnetometer is a clue, not proof.) GHOST — FOR WHEN YOU WANT THE CHILL Kill the lights. The K2 lamp bar flares as the field shifts around you. Four anomaly levels, eerie skins, a shareable Activity Score. Pure entertainment — and ridiculously fun to film. ZERO PERMISSIONS, ZERO CREEP No location, no microphone, no camera, no account, no ads. Nothing ever leaves your phone. Free to detect. Veil Pro unlocks recording & replay, PDF/CSV export, unlimited reports, the hotel camera sweep, every ghost skin and 100 Hz precision — as a Lifetime unlock, a Yearly plan with a 3-day free trial, or a Weekly pass for a single Halloween week. Readings are for reference, not health, safety, or medical advice. Veil measures magnetic fields only; it does not measure Wi-Fi, Bluetooth, 5G or other RF. Ghost Mode is for entertainment. — Veil Pro — Unlock all professional features with Veil Pro: • Weekly — $1.99 (auto-renewable) • Yearly — $9.99 with a 3-day free trial (auto-renewable) • Lifetime — $14.99 one-time purchase Payment is charged to your Apple Account at confirmation of purchase.

Verdict

The call

The clearest difference is rating: Veil at 5.0 against EMF Detector's 3.9. Veil also leads on ads (none vs shown). EMF Detector's advantage is in-app purchases (none vs 3) and update cadence (every 5 days vs every 4 months). On price, device support and iOS requirement there is nothing between them.
