Unseen — Sense the Invisible

UNSEEN turns the many sensors hidden inside your phone into a real-time HUD for the invisible world around you — magnetic fields, Wi-Fi 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.

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 in real 3D space; pin a marker on the strongest
source
• Wi-Fi AR — overlay your Wi-Fi signal as a 3D heatmap as you move through a room

━━━ SENSORS YOU CAN EXPLORE ━━━

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

━━━ 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 ━━━

Deutsch, Português, Русский, العربية. RTL fully supported.

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.
