Hold the phone steady. Watch the meter. Listen. Ghost Detector turns your phone into a paranormal investigator's pocket toolkit. The EMF scanner reads the magnetometer field around you and pulses when something shifts. The spirit box cycles voices the room should not have made. The EVP recorder captures what you cannot hear on your own. WHAT THE METER SHOWS The needle answers the room. Calm fields stay green. Spikes climb yellow into red. Some spikes have explanations. Some do not. You will learn which is which. SPIRIT BOX Three hundred and twenty three voice clips cycle through the audio. Some sound like words. Some sound like answers to questions you just asked out loud. The pattern is the point. EVP RECORDER Press record. Ask. Stop. Listen back. The recordings hold things you did not hear in the room. INVESTIGATION FIELD KIT Built for the kind of night where the house is quiet and you want to know why. Built for friends sharing the phone around a circle. Built for the curious. For entertainment purposes. Ghost Detector is a paranormal investigation toy that takes itself seriously. The readings are theatre. Take them as seriously as you want to. Open the kit tonight.

EMF Detector turns your phone into a real-time magnetic field detector. Point it at wiring, a running appliance or a magnet and watch the reading move — a pocket EMF meter that shows what is actually around you, in microtesla (µT) or milligauss (mG). A MAGNETIC FIELD METER YOU CAN READ AT A GLANCE The main screen is a full instrument panel: a large live number, an analog gauge, the X, Y and Z axes, and a rolling 60-second graph so you see the trend and not just the moment. Peak hold keeps the highest value you passed through, and live Min / Avg / Max show what the room has been doing. Switch between µT and mG whenever you like — the same units a gauss meter or gaussmeter shows — and your choice is remembered. Readings fall into three bands so a number means something. Below 60 µT is Typical, 60–100 µT is Elevated, and 100 µT or more shows as a Strong Field — a sign that something magnetic or powered is close. Turn on the alert and the app sounds and vibrates when the reading crosses your threshold, so you can sweep a wall without staring at the screen. FIND THE SOURCE Move slowly past outlets, cables, speakers, laptops, a running microwave, the breaker panel or a fridge door. Used as an EMF scanner the value climbs as you close in, and peak hold marks the strongest spot you found. The built-in Common Readings table lists typical ranges for more than ten everyday sources and highlights the row your reading falls into — so you can tell the Earth's field from something live inside a wall. GHOST DETECTOR MODE For ghost hunting nights, switch to Ghost Detector: a dark, reactive K-II style display — the K2 meter look ghost hunters know — where the same total magnetic field drives a five-level segment readout and an apparition that grows stronger as the field rises. It is free, it uses no separate sensor and no hidden logic — and it is clearly labelled as entertainment. RECORD AND REVIEW Record a session while you walk a room. The app logs a one-second timeline with duration, Min, Avg, Max and Peak, and keeps it in History so you can reopen it, see the chart, rename or delete it. Export a session as CSV — timestamp, x, y, z, magnitude, unit — to keep or share. WHAT IS IN THE APP • Live magnetic field meter in µT and mG • Analog gauge, large readout and X / Y / Z axes • 60-second chart, peak hold, Min / Avg / Max • Typical / Elevated / Strong Field bands • Threshold alert with sound and haptics • Ghost Detector, a free K-II style reactive mode • Always-on spike rejection so the number does not jitter • Session recording with a 1 Hz timeline and statistics • History list, session chart, rename and delete • CSV export through the system share sheet • Common Readings table with live row highlighting • Guide to EMF, reading levels and calibration • Fully offline — no account, no network, no ads HONEST ABOUT WHAT A PHONE CAN MEASURE Your phone has a magnetometer, the same sensor the compass uses. EMF Detector reads the total magnetic flux density near that sensor and nothing else. It cannot measure radio frequency — no Wi-Fi, no Bluetooth, no 5G, no ionizing radiation — because a phone has no RF sensor. The bands help you locate sources; they are not a health or safety verdict, and this is not a substitute for a calibrated professional EMF meter. Ghost Detector is entertainment and cannot identify anything paranormal. For the steadiest reading, move your phone in a figure-8 to calibrate, take off magnetic cases and mounts, and move slowly. Exporting sessions as CSV requires a subscription (weekly or monthly, each with a 3-day free trial). Everything else here — the meter, the bands, the fixed alert, Ghost Detector, the reference table and your three latest sessions — is free.
