Spectra: Ghost Hunting Kit

Spectra is a ghost hunting app that turns your phone into a serious paranormal investigation kit: EMF detector, spirit box, EVP recorder, SLS camera, REM pod style alarm and ghost camera, with no ads, no subscriptions and no fake readings. Made for ghost hunters, paranormal investigators and anyone curious about haunted places.

NO GIMMICKS
Every reading comes from your phone's real hardware: magnetometer, motion sensors, light, pressure, microphone and camera. If your phone doesn't have a sensor, Spectra tells you instead of faking it. Readings taken while the phone was moving are flagged, so you can tell a real spike from a wobble.

FREE TO START
• EMF meter with K2-style lights, gauge, zeroing and a live graph
• Spirit box with a word reel of 3,500+ words that stops only when a sensor or sound triggers it, and tells you what triggered it
• EVP recorder with raw microphone capture, live spectrogram, voice detection, slow-down and reverse
• Red light, case files and a full user guide

SPECTRA FULL: ONE PAYMENT, YOURS FOR GOOD
• Live radio spirit box that sweeps real broadcast stations, like a professional scanner
• Words from the radio: transcribes what was really said at that moment and shows which station it came from
• Phantom Vision, a mode found only in Spectra: the camera's AI looks for human figures while depth measurement checks whether anything is physically there, and it records when they disagree. Uses a depth sensor, Google's motion depth or an on-device AI depth estimate, so it works on almost any phone. Includes a 3D Matrix scanner that sees up to 20 m: wireframe, solid or point cloud, in real colour or coloured by what it is (people, plants, buildings), saved as 3D models you can open in Blender or MeshLab
• SLS camera with stick-figure detection that also recognises pets, dolls and soft toys
• Ghost Cam with night vision, a Twilight low-light mode, a motion trap and evidence video
• Animal recognition on every camera: cats, dogs, birds and insects are labelled so you can rule them out
• REM alarm that watches six sensors, a Music Box trap that plays when disturbed, a geophone and environment sensors
• Professional mode: a live multi-sensor dashboard with raw values and spectrogram
• Spectra Analyst: reviews every case, finds activity seen on several instruments at once and lists the everyday explanations to rule out
• AI assistant that runs on your phone's own free AI where available, with no account and no extra cost
• Export case reports and back up to Google Drive, OneDrive or Dropbox

APPROACH ALERT
Like a parking sensor: beeps get faster as something gets closer to you, on every instrument and camera. It goes quiet while you move the phone, so it doesn't false-alarm.

CASE FILES
Every reading, recording, photo and note goes on a time-stamped timeline. Export a full report with WAV recordings, photos and data.

SIMPLE OR PRO
Big, friendly buttons for your first hunt, or a full dashboard for experienced teams.

PRIVATE BY DEFAULT
Your recordings, photos and cases stay on your phone unless you choose to back them up or share them. No sign-up and no ads.

WHO IT'S FOR
Whether you're exploring a haunted house, joining a ghost hunt or investigating strange noises at home, Spectra gives you real paranormal investigation tools in one app: a ghost detector built on measurement, not guesswork.

Please note: Spectra's instruments measure physical conditions. They can't prove a paranormal cause, and Spectra always shows you the ordinary explanations to check. For entertainment and investigation.
