SpectraBox: Spirit Box EVP

Ghost Detector & EMF Meter

Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.

SpectraBox is a ghost-hunting toy that is honest about what it is. The spirit box shows words on screen in real time and generates every sound on your device: there is no radio and no internet, so it works in airplane mode and can never stream fake output or pick up foreign-language stations. Spirit Lens adds an SLS-style body-pose camera overlay, rendered entirely on-device. Every session is saved with a timestamped transcript you can play back and export. For entertainment purposes only. WORDS ON SCREEN, IN REAL TIME - Watch each word appear as the spirit box speaks it - A scrolling, timestamped session transcript, not just audio - A live EMF meter using your phone's real magnetometer SPIRIT LENS: AN SLS-STYLE CAMERA - A body-pose overlay live on your camera, on any iPhone, no LiDAR needed - Confidence-scored detections, labeled honestly as artifacts - A free one-minute preview; Pro unlocks unlimited time plus snapshot and clip capture TURN SESSIONS INTO SHAREABLE CLIPS - Clip Studio renders a session into video: words, EMF trace, and audio - The share card is free and unlimited - Pro exports a full video clip 100% ON-DEVICE, NO FAKERY - The spirit box is procedural sound synthesis, not a radio scan - No internet and no network calls: it works fully in airplane mode - No accounts, no tracking, no ads, no third-party SDKs SAVE AND SHARE YOUR SESSIONS - Record a session and play it back in the app - Export the transcript as a CSV or text file to share as "evidence" - A running, timestamped log of every word and EMF reading FREE FOREVER - The full EMF meter - A one-minute spirit-box session with real-time words on screen - A visible session log - The Spirit Lens camera overlay, live for one minute - The Clip Studio share card, unlimited SPECTRABOX PRO (one-time $7.99, no subscription) - Spirit Lens: unlimited time, plus snapshot and clip capture - Clip Studio: rendered video clips with words, EMF trace, and audio - Case Files: group sessions into an investigation, with a PDF export - Five theme packs: Old Town, Seance, Cold Spot, Static, All Hallows - Voice Lab: whisper, deep, and airy voice presets - The correlation view: see exactly which words fired during an EMF spike - Red-light mode to preserve your night vision - Unlimited session length - Full session recording, playback, and CSV/text transcript export - The Apple Watch companion for hands-free sessions - A Live Activity session timer on your Lock Screen and Dynamic Island - Background sessions so the box keeps running while you film - Sweep-rate and EMF calibration controls WHY SPECTRABOX - Honest by design. Procedural, on-device sound means nothing is streamed and nothing is faked. What you see is what your phone made. - Honest about the camera too. Spirit Lens labels low-confidence detections as artifacts, not evidence. - It shows the words. The most-loved spirit-box feature, done right: real-time text plus a transcript you can keep. - No subscription. The core is free forever, and Pro is a single one-time purchase. - Yours, privately. Your sessions and camera processing stay on your device. For entertainment purposes only. SpectraBox uses your phone's real magnetometer and camera, and generates all sounds on your device. Results are not evidence of paranormal activity.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

Four new Pro tools this update: - EVP Analysis Lab: record the real sound of the room during a session, then scrub, slow down, reverse, and tag what you hear. - Overlay Evidence Camera: record real video with your live EMF reading, the spirit box words, and a timestamp burned right into the clip. - K2 Instrument Pack: the classic 5-LED field meter, with a baseline calibration wizard and a rising proximity tone. - Custom Word Banks: write your own words and categories, then use them as the spirit box's vocabulary. Everything free stays free. SpectraBox Pro is still one purchase, yours forever, no subscription, ever. And if you buy today, that price is locked in for you even if it costs more for new buyers later. Plus small fixes and polish throughout.
