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. Disputes resolved at nearest cemetery, midnight–3 AM. Note: Ghost Hunter is designed for entertainment purposes. Paranormal results cannot be scientifically verified.
