SpectraEMF
Read full descriptionHide full description
SpectraEMF is a ghost-hunting EMF meter that is honest about what it is. It reads your phone's real magnetometer (the same sensor the compass uses) and shows it as a glowing K2-style LED bar and a 0-to-100 readout. Because it is a genuine sensor, it reacts to actual magnetic fields and cannot be faked or scripted. Record a reading and keep the whole timeline. For entertainment purposes only. A REAL K2-STYLE METER - A five-segment LED bar that climbs from green to red with the field - A live 0-to-100 readout from your phone's actual magnetometer - Calibrate to your room with one tap so the meter starts at zero IT CANNOT BE FAKED - The reading is a real sensor, not a random number generator - 100% on device: no internet, no accounts, no ads, no third-party SDKs - It works in airplane mode, and the alert beep is generated on device ALERTS, RECORDINGS, AND EXPORT - A beep and a buzz when the field crosses your alert level - Record a reading and review the whole timeline afterward - Export any reading as a CSV or text file to share as "evidence" FREE FOREVER - The full live K2 EMF meter, the LED bar, and calibration - A basic threshold alert - A timed recording you can save and view SPECTRAEMF PRO (one-time, no subscription) - Unlimited recording length and the full reading timeline - Export readings as CSV or text - The Apple Watch meter for hands-free hunts - A Live Activity readout on your Lock Screen and Dynamic Island - Custom alert level and sensitivity WHY SPECTRAEMF - Honest by design.

Ghost Camera

Point your phone into the dark and see what it finds. Ghost Camera is an SLS-style ghost-hunting camera made for entertainment: a full-screen viewfinder with a live paranormal HUD, eerie words, a clicking Geiger-style soundtrack, and spooky camera effects. Take it to a sleepover, a night walk, or wherever the lights flicker. POINT IT INTO THE DARK Everything on screen follows a restless spirit-strength meter. The LED bar creeps from green to red, the clicks come faster, and every so often a word drifts over the image โ COLD. WATCHING. BEHIND YOU. ENTITY TRACING (PRO) When a human-shaped figure enters the frame, Ghost Camera traces it with a glowing skeleton, colored by the current spirit strength. If you've watched paranormal TV, you know the look. CAMERA FILTERS & EFFECTS Five looks for that found-footage feel: a green Glow FX, a heat-map style Heat FX, grainy VHS FX, and the color-shifted Spectrum FX. They're visual filters over your device's normal camera โ pure entertainment, no special hardware involved. CAPTURE AND SHARE Photos and videos come out exactly like the screen: HUD, effects, words and traced figures baked right in, with an optional location tag. The built-in gallery keeps your captures together, and the logbook remembers every word โ when it appeared, how strong the signal was, what the sensors were doing. LIVE SENSOR DASHBOARD Your device's real sensors, one spooky screen: magnetic field, acceleration, pressure and gyroscope, each with its own history graph, plus a live compass. GHOST CAMERA PRO Pro removes the ads, unlocks the premium effects and the tracking skeleton, drops the watermark, and opens the full wordbank. You can subscribe or buy it once and keep it forever โ the app shows each option with its name, duration and price before you decide. Subscriptions renew automatically unless you cancel at least 24 hours before the period ends, and you can manage or cancel any time in your App Store account settings. FOR ENTERTAINMENT One thing said plainly: Ghost Camera is for fun. The readings, words and detections are generated by the app and aren't evidence of anything paranormal โ reflections, posters, coats and screens can all set it off. Investigate, don't assume.

Verdict
The clearest difference is in-app purchases: Ghost Camera at none against SpectraEMF's 1. Ghost Camera also leads on update cadence (daily vs every 4 days). SpectraEMF's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
