The ultimate toolkit for paranormal investigators has arrived. SpectraScan is a production-ready, professional-grade ghost hunting application designed for the modern investigator. Leveraging the advanced sensor array of your iPhone, SpectraScan fuses multiple data streams into a single, immersive experience. Whether youβre a seasoned researcher or a weekend hobbyist, our suite provides the data you need to document the unknown. REAL-TIME SENSOR FUSION Don't just look at one meter. SpectraScan monitors EMF (Magnetometer), Motion (Accelerometer/Gyroscope), Atmospheric Pressure (Barometer), and Audio frequencies simultaneously. Our proprietary Activity Score algorithm (0-100) analyzes these inputs to highlight significant paranormal anomalies in real-time. AR HUNT MODE Step into the hunt with an immersive Augmented Reality overlay. Using ARKit 6 (and LiDAR on Pro models), SpectraScan maps your environment and visualizes potential "entities" based on sensor spikes, providing distance tracking and threat-level analysis. EVP STUDIO Capture Electronic Voice Phenomena with our professional audio suite. Featuring real-time waveform visualization and a randomized frequency "Spirit Box" mode, you can record, play back, and manage your evidence log directly within the app. EVIDENCE LOG & HISTORY Keep a detailed timeline of every investigation. Track your sessions with GPS tagging, duration, and peak activity levels. Export your data to analyze patterns and build your case file. KEY FEATURES: EMF Detector: High-frequency magnetometer monitoring with anomaly alerts. Vibration Analysis: Detect the slightest knocks or movements with 100Hz sensitivity. Pressure Monitoring: Track barometric "cold spots" or atmospheric shifts. Immersive Design: Dark, glassmorphic UI with neon accents optimized for night-time use. Privacy First: No internet required. All data and audio recordings stay locally on your device. For entertainment: SpectraScan shows real readings from your iPhone's sensors, but it cannot prove paranormal activity. Have fun and investigate safely. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
