Welcome to the Ghost-o-Matic app, created by the Society for the Pursuit of the Reputedly Undead, Namely Ghosts, also known as SPRUNG, for use with the Ghostkeeper’s Journal and Field Guide. If you have not yet acquired your Ghostkeeper’s Journal, kindly follow this link: https://www.carltonbooks.co.uk/the-ghostkeeper-s-journal-and-field-guide-hb.html to purchase the book. You will need the book to trigger the functions of the Ghost-o-Matic app. This app uses groundbreaking augmented reality to reveal hidden messages, missing pages, metaphysical phenomena, mysterious puzzles and even ghosts in and around the pages of the book. We need your help. A SPRUNG operative has gone missing. All that remains of him is his Ghostkeeper’s Journal – you’ll need the Ghost-o-Matic app to break the secrets hidden inside. Our operative’s name is Agamemnon White – child prodigy, ecto-genius, and tuna sandwich obsessive. He is also head of Ghostkeeping for the Western region, and was collecting the most powerful ecto-energy types known to man in his Journal. Download the Ghost-o-Matic app, synchronise it with your copy of the Ghostkeeper’s Journal, join SPRUNG, and use the book and app together to retrace Ag’s trail and help us rescue him. But beware… the moment you open the book, you will release the ghosts Ag trapped inside. It will be up to you to recapture them with the Ghost-o-Matic app and solve the mystery of his disappearance… without disappearing yourself! This immersive storyworld of the Ghostkeeper’s Journal, told through the book and the app, represents a brand new kind of interactive fiction for older kids and young adults, reinventing the book for the screen generation and using AR technology in a wholly new way. The app delivers more than fifty animation sequences, digital puzzles and personalised achievements as part of an over-arching story about this mysterious Ghostkeeping society and its dark secrets. Join SPRUNG through this app and experience the next generation of storytelling today. To begin, launch the app and point your device’s camera at your Journal to begin your hunt. In-app messages will guide you through the process of joining SPRUNG and catching your first ghost. NOTE: Once downloaded, the Ghost-O-Matic app does not require WiFi.

Ghost Hunter — AI-Powered Paranormal Detection Turn your iPhone into a professional-grade ghost hunting instrument. Ghost Hunter combines real device sensors with AI vision detection and Boo Labs-patented paranormal technology to find, analyze, and document what lurks in the dark. HUNT! — AI Ghost Camera Point your camera and let the AI do the work. Ghost Hunter's on-device YOLO vision model scans every frame for paranormal entities, drawing detection boxes around anything suspicious. Use your camera live or pick a photo from your gallery. Serious Mode unlocks real-time AI detection with custom downloadable models. F.A.R.T. — Frequency Analysis & Resonance Translator The ghost-patented spirit communication instrument. F.A.R.T. uses your real microphone to capture EVP recordings, then blends them with a frequency sweep spirit box. Detected "transmissions" are spoken aloud in a randomly selected voice — every session sounds different. Patent #0000000013. W.H.I.F.F. — Waveform Harmonic Interference Frequency Finder Your phone's magnetometer becomes a paranormal odor detector. W.H.I.F.F. reads real electromagnetic field data and presents it as ghost smell intensity on a glowing analog gauge. Four odor zones from "Fresh grave dirt" to "Pure ectoplasmic musk." Haptic feedback escalates as the ectoplasmic musk reaches critical levels. Patent #⌭∞⌭-BOO. SETTINGS — Detection & Models Configure AI detection models, toggle Serious Mode (real YOLO class names vs. ghost names), and set Ghost Preferences to tune which object types attract the most paranormal activity. Download additional detection models directly to your device. Ghost Hunter Premium — $1.99/month Unlock Serious Mode with full AI detection, custom models, and advanced detection capabilities. Subscription auto-renews monthly. Cancel anytime in App Store settings. Boo Labs™ — Ghost-Patented Technology All instruments protected under Afterlife Patent Law.

Verdict
The clearest difference is rating: NDS Ghost Hunter at 4.7 against Ghost's 4.1. NDS Ghost Hunter also leads on review sentiment (100% vs 59%). Ghost's advantage is in-app purchases (none vs 1) and update cadence (every 2 months vs every 9 months). On price, ads and device support there is nothing between them.
