Something is in the room with you. Find it. Ghost Detector: Ghost Box turns your iPhone or iPad into a paranormal field kit — a camera radar that reveals apparitions around you, a spirit box that answers your questions, an EMF meter driven by the real magnetometer, and an EVP tape recorder. Every catch is saved to your own case file. CAMERA SCAN — RADAR AND APPARITIONS • Hold up your phone and turn slowly; the radar shows how close the entity is • Apparitions manifest in the live camera view — the closer you get, the stronger they appear • The moment one shows itself, an evidence photo is captured automatically GHOST BOX SB-33 — SPIRIT BOX • AM radio sweep, 530–1730 kHz, with real static and a voice pushed through a radio filter • Tap a question key, or switch on Listen and ask out loud • Every session has its own entity — a name, a mood and its own way of answering • The entity answers in your language: English, German, French, Spanish, Italian, Portuguese, Russian, Japanese, Korean or Chinese • Silence is an answer too, and the whole session is saved to a log you can share EMF METER EM-33 • Live readings from the built-in magnetometer in microtesla • Needle dial, K-II style LED ladder, history graph, peak hold and reset EVP RECORDER RX-33 • Ghost tapes that unlock as you catch apparitions • Stereo VU meters and tape deck controls CASE FILE • Every apparition is stored with the time and the EMF reading • Share a photo or a Ghost Box session in a tap FREE AND PREMIUM Ghost Detector is free to play: 20 ghost catches a day, 12 Ghost Box replies a day and the standard entities. Premium removes the limits: • Unlimited ghost scans • Unlimited Ghost Box replies • Every entity, including the rarest ones • Evidence photos without a watermark SUBSCRIPTION • Weekly — $3.99 with a 3-day free trial • Yearly — $24.99 Prices are in US dollars and may vary by region.

Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://thirtythreeapps.com/ios-ghost-detector-privacy-policy FOR ENTERTAINMENT PURPOSES ONLY Ghost Detector: Ghost Box is a simulation made for fun and for a good scare. Ghosts, spirit box replies and radar contacts are generated by the app. The EMF meter shows real magnetometer values, but the app does not detect real paranormal activity. Rated 13+ for horror themes.
