Spirit Boxly
EMF meter app
Does an iPhone have an EMF meter? Yes — a magnetometer.
Every modern iPhone ships a magnetometer for Compass. Spirit Boxly reads that sensor and plots it like a field meter. The number is a real magnetic measurement. It is not a ghost.
Magnetometer versus the wand in the ghost shop
A typical handheld “EMF detector” sold for hauntings is often a single-axis milligauss meter, sometimes poorly shielded, sometimes just an LED toy. An iPhone magnetometer is a 3-axis chip meant to find magnetic north. It is sensitive to:
- Earth’s field (tens of microtesla — the baseline of every room on Earth)
- Speakers, cases with magnets, MagSafe wallets, fridge doors
- AC wiring and appliances, seen as a changing field as you move past them
- The phone’s own motion: rotating the device rotates the vector
It will not tell you “spirit energy.” It will tell you the field changed. That is still useful if you want a repeatable anomaly — the same corner, phone still, same bump — instead of a walk-by of the breaker panel.
Set a room baseline or the graph is theater
Put the phone on a wood table, away from the fridge and the soundbar. Wait. That quiet number is the room plus Earth plus the phone. Spirit Boxly lets you lock that as a baseline and watch peaks against it. Field radar shows direction and how messy the motion is.
If you walk, the plot will dance. That is geometry, not a presence. Investigate standing still or set the phone down. Note magnets in the case. The iOS Simulator cannot read a magnetometer; it shows a labeled demo signal so you do not mistake development for a haunting.
A ten-minute EMF walk that is not a con
-
Map the boring sources
Wi-Fi router, microwave, panel, TV. Write them in the case notes.
-
Baseline one surface
Phone still. Record thirty seconds. That is your “nothing happening” line.
-
Test one claimed spot
Same orientation, same height. Look for a repeat, not a single spike.
-
Align the clock
If you also run EVP or a spirit box, the interesting claim is coincidence on a timeline — not a bigger number.
What stays free in Spirit Boxly
The EMF meter and field radar stay free. They are the honest sensors. Spirit Box and standalone EVP have a three-minute free window and one saved investigation. That split is deliberate: anyone can learn what the magnetometer does before they buy a lifetime unlock.
iPhone EMF FAQ
Does an iPhone have an EMF meter?
It has a magnetometer. An EMF meter app can display that field. It is not a laboratory probe and it does not detect ghosts.
Why does the reading jump when I walk?
You are moving a 3-axis sensor through Earth’s field and past metal. Keep the phone still to judge a location.
Is the EMF meter free in Spirit Boxly?
Yes, with field radar. Physical iPhone only for real data.
