SpectraScan
Read full descriptionHide full description
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. 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/

GhostScope is a ghost-hunting kit for fun. It cannot detect ghosts: it shows what your phone's sensors pick up and adds playful tools. EMF METER: shows your phone's real magnetometer reading in µT or mG, with a 5-LED bar, peak and live graph. Magnets and speakers move it. Not a scientific instrument. EVP RECORDER: record with the microphone and play back slowed down. Free: 1 recording a day, plus 1 per rewarded ad. SPIRIT RADAR: a radar animation for atmosphere. Blips are random, a visual effect only. SPIRIT BOX: a radio-sweep game. Words are picked at random from a built-in list; a word drops sooner when your EMF reading jumps. Word history included. Entertainment only: nothing is being detected. SENSORS: live pressure, vibration and sound level from the sensors in your phone. PENDULUM: type a yes/no question; the answer comes from how you tilt the phone. HUNT LOG: saves your EMF sessions (duration, peak, events), the last 100. Free with ads. No ads while a hunt is running. GhostScope Pro (subscription or one-time purchase) adds unlimited EVP recordings, m4a export and sensitivity boost above x1.4, and removes ads. No account. Readings and recordings stay on your device. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://ghapps1.wordpress.com/privacy-policy/

Verdict
The clearest difference is ads: SpectraScan at none against GhostScope's shown. GhostScope's advantage is update cadence (monthly vs every 5 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
