Spirit box app for iPhone
Spirit Boxly is a ghost detector toolkit: live EMF, EVP recording, field radar, and a procedural spirit box on one timeline. Sensor readings are real. Interpretation stays yours.
Free to try · iPhone · Entertainment and experimental use
Record sensors, audio, observations, and a complete report.
Read nearby magnetic fields with analog and digital readout, a room baseline, and spike history. The iPhone uses its magnetometer, not a toy needle.
Run a seeded, on-device sweep with fragment banks, blind review, and question windows—not a broadcast radio scan. Read what a spirit box app is.
Capture and mark audio against EMF, sound, and your notes. The original stays intact. How to record EVP on iPhone.
Visualize magnetometer direction and motion quality while you walk a room.
Built for curious, experimental investigations — a documented session, not a novelty gauge.

Why investigators search for Spirit Boxly
Most “ghost detector” apps sell a flashing meter. Spirit Boxly is named for the search people actually run: a spirit box they can take into a quiet room, ask a question, and later compare with EMF and tape.
Sweeps are procedural audio generated on the phone. You get a run seed, blind review, control sessions, and timestamps. That makes Spirit Boxly useful for people who want a method—a home walkthrough, the Estes method, or a first ITC experiment—without pretending the iPhone is scientific proof of a haunting.
A spirit box app plays a controlled audio sweep and logs short fragments so you can compare timing with questions, EMF changes, and room recordings. Spirit Boxly generates that sweep on-device. It is not a radio tuner and does not claim verified spirit communication. The longer answer is on what a spirit box is.
On a physical iPhone, the EMF meter reads the magnetometer. Set a room baseline, watch peaks, and look for repeatable shifts while the phone stays still. The simulator uses a labeled demo signal. How the iPhone EMF meter works.
Yes. Full investigations record microphone audio alongside markers. Use headphones so generated sweep audio is less likely to bleed into the tape. Markers never modify the original file. See how to record EVP.
EMF and field radar stay free. Free Spirit Box and EVP sessions last up to three minutes, with one saved investigation. Lifetime Pro removes ads and unlocks unlimited cases.
Get the app
Open the App Store listing, try a first investigation, and keep the report on your device.
Available on iOS as Spirit Boxly: Ghost Detector
(com.ghosthunt.boxly). iPhone sensors measure magnetic fields, motion, and
sound; they cannot scientifically confirm paranormal activity.
