Unseen: EMF & Sensor Detector

About Unseen: EMF & Sensor Detector

UNSEEN turns the many sensors hidden inside your phone into a real-time HUD for the invisible world around you — magnetic fields (EMF), Wi-Fi & cellular signals, vibration, ambient light, air pressure, screen flicker, sound levels, even gamma radiation hits. Then step into AR and watch those invisible fields float in 3D space around you.

Use it as an EMF meter, magnetometer, metal detector, Wi-Fi signal analyzer, decibel / sound level meter, lux light meter, barometer & altimeter, vibration / seismometer, screen-flicker (PWM) tester, and a hobbyist gamma-ray detector — all in one sensor toolbox.

No accounts. No tracking. No cloud uploads. Everything runs on-device.

━━━ SEE IT IN 3D AR ━━━

• Magnetic AR — walk around and watch glowing orbs map the magnetic field (EMF) in real 3D space; pin a marker on the strongest source • Wi-Fi AR — overlay your Wi-Fi signal strength as a 3D heatmap as you move through a room

━━━ SENSORS YOU CAN EXPLORE ━━━

• Magnetic field / EMF meter — find nearby magnets and metal objects (metal detector), explore local field strength, calibrate compass • Wi-Fi & cellular RSSI — a signal analyzer that maps signal strength room by room • Vibration & micro-tremor — a pocket seismometer to see how stable a surface really is • Ambient light — a lux light meter that tracks brightness changes around you • Barometer & altitude — an altimeter that catches sudden air-pressure shifts • Screen flicker (PWM) — check displays for invisible flickering • Sound level — a real-time decibel meter / sound meter (dBA / dBC) • γ-ray hits — cover the camera with black tape to spot occasional cosmic-ray pixels (for fun & learning)

━━━ RECORD, REVIEW & EXPORT ━━━

• Record a measurement session on any sensor with one tap • Browse your full measurement history with charts and stats • Export sessions as CSV or professional PDF reports

━━━ HUD-FIRST DESIGN ━━━

Inspired by sci-fi cockpit panels: monospace digits, neon accents, scanlines, radar dashboard. Built to be readable at a glance, not pretty in screenshots.

━━━ MULTI-LANGUAGE ━━━

10 languages bundled: English, 简体中文, 日本語, 한국어, Español, Français, Deutsch, Português, Русский, العربية. RTL fully supported.

━━━ PRIVACY ━━━

• All sensor readings stay on your device. • No analytics SDK, no behavioral tracking. • Anonymous AdMob banner / native ads only. • Location is only requested for Wi-Fi SSID readout (Android requirement).

━━━ UNSEEN PRO (one-time, lifetime) ━━━

• Unlimited AR sessions • Unlimited session recording + measurement history • Unlimited CSV / PDF report export • Remove all ads • Premium HUD themes: Danger Red, Military Blue, CRT Amber

No subscription. Pay once, keep forever.

━━━ LIMITS YOU SHOULD KNOW ━━━

This app is an educational and entertainment tool, not a safety instrument. Phone sensors are not lab-calibrated. Do not use for medical, legal, or professional radiation assessment. It cannot detect radio-frequency radiation (Wi-Fi, cellular, 5G). This is a curiosity and learning tool, not a paranormal or safety device.
