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 β€” 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 β€” the same quantity the classic EMF meters read. Everything you see is real. PROFESSIONAL β€” 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 β€” 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 β€” smoke detector, TV, alarm clock, outlets, vents, mirror β€” 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 β€” 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 β€” 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 β€” 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. β€” Veil Pro β€” Unlock all professional features with Veil Pro: β€’ Weekly β€” $1.99 (auto-renewable) β€’ Yearly β€” $9.99 with a 3-day free trial (auto-renewable) β€’ Lifetime β€” $14.99 one-time purchase Payment is charged to your Apple Account at confirmation of purchase.
