## What is SpectraScan App?

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 you’re 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.
