Ghost Detector vs EMF Detector・Ghost Detector
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Ghost Detector
This app simulates paranormal detection using four simulated technologies: RADAR, EMF, Infrasound & EVP, and Ion detection. It aims to identify irregular energy fluctuations and unusual sounds in the environment for entertainment purposes.
- Simulated RADAR for energy fluctuations
- EMF detector for electron vibrations
- Infrasound & EVP sound analysis
- Ion detector for electric field charges
- Entertainment-focused paranormal simulation

This app mimics the four most important technologies to detect paranormal activity. RADAR: A radar works by transmitting a signal through electromagnetic waves called radio waves. These waves bounce off certain types of distorted, unstable and abnormal signals. In other words, the radar will detect any irregular energy or fluctuations in the environment. EMF: An EMF detector finds electron vibrations in a given area. This is similar to a radio antenna. INFRASOUND & EVP: InfraSound is sound that is lower in frequency than 20 Hz, which is the normal limit of human hearing. Electronic voice phenomena (EVP) are sounds usually found in background noise from stray radio transmissions which sounds like static, but it can also pick up odd sounds. IONS: An Ion detector can detect positive and negative ions within an electric field. An ion is a positive charge. When there is high amounts of positive electromagnetic discharges it is thought to be due to paranormal activities. Disclaimer: This app is made for fun and entertainment purposes only.

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.

Verdict
The clearest difference is rating: EMF Detector・Ghost Detector at 5.0 against Ghost Detector's 4.3. EMF Detector・Ghost Detector also leads on update cadence (every 3 weeks vs every 3 months). Ghost Detector's advantage is ratings volume (161 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Ghost Detector sells 1 one-off in-app purchase and EMF Detector・Ghost Detector sells 2 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.
EMF Detector・Ghost Detector holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Ghost Detector has 161 ratings behind it against 1, so its average is the more settled of the two.
Ghost Detector ships an update every 3 months, EMF Detector・Ghost Detector every 3 weeks. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
