SPECTRAL turns your iPhone into a ghost hunting kit: EMF radar, spirit box, SLS camera, EVP recorder and séance board in one app. It reads your phone's REAL magnetometer, motion sensors and microphone and turns them into atmospheric investigation tools. SLS CAMERA Maps human-shaped figures onto your camera feed in real time. Sometimes it finds you. Sometimes it finds something smaller in the corner that walks away on its own. Skeletons are saved into your photos and videos. EMF RADAR Live readings from your phone's magnetometer on a signal graph. The meter climbs as fields shift and blips appear on the radar. Temperature, voltage and frequency readouts track anomalies. SPIRIT BOX 6 channels, each with its own voice and word bank: STANDARD, DEMON, CHILD SPIRIT, SOLDIER'S ECHO, SÉANCE and ANCIENT. Speak out loud and entities answer when they hear you. Capture and share any word the instant it comes through. EVP RECORDER Record sessions from the room around you. Peaks are tagged as anomalies automatically, so you can jump to the moment something answered. SÉANCE BOARD Ask a question aloud and watch the planchette spell out the reply, letter by letter. VISION CAMERA Seven modes, including Green Glow, Heat Map Colors, Blacklight Glow, Ectoplasm, Shadow Veil and Specter Mode. Entities manifest without warning and orbs drift through frame. Every photo gets an entity type, threat level and confidence score. RECORD & SHARE Film your hunt with overlays, skeletons and orbs and share it to your feed. Standard clips run 30 seconds with a watermark; PRO records up to 3 minutes without one. INVESTIGATIONS 30+ case files in haunted places: abandoned asylums, forgotten chapels, sunken parishes, lighthouses. Each has a backstory, zones to sweep and entities to identify. A new case rotates in daily and one stays open to everyone each week. Close a case to get an animated Case Closed card. EVIDENCE JOURNAL Every capture is archived and classified. Climb 4 investigator ranks, keep your daily streak, complete daily missions and unlock radar themes in the Season Pass. Halloween, full moons and the 3 AM witching hour intensify activity. SPECTRAL PRO Every channel, filter and case, the custom case builder, 3-minute video without a watermark, longer recording sessions, Deadwave mode, audio effects, entity forensics, sensor calibration and no ads. Monthly, yearly or a one-time Lifetime purchase. Monthly and yearly Pro are auto-renewing subscriptions. Payment is charged to your Apple ID account at confirmation of purchase.
