Right now, your device is reading a dozen physical layers of reality simultaneously — electromagnetic fields, acoustic signatures, motion, radio broadcasts from every device around you. Most people have no idea. 38 experiments that change that.

◯ open meta layer

rf & radio

BLE broadcast scanner

Every device within 10m is screaming its presence. Here's what's advertising right now.

livebluetooth le

EM field detector

Walk near a power line or appliance. Your magnetometer sees the field warp in real time.

livemagnetometer

compass anomalies

Rebar, wiring, pipes — the hidden skeleton of every building you enter, revealed by your compass.

partialmagnetometer

WiFi density map

Connection speed, RTT, and network congestion reveal how many devices are fighting for bandwidth around you.

livenetwork api

acoustic

full spectrum FFT

Mains hum, HVAC resonance, ultrasonic devices — the acoustic fingerprint of your space.

mains hum detector

50Hz or 60Hz — tell which country you're in acoustically. Find hidden electrical equipment.

livemicrophone · fft

ultrasonic detector

"Silent" pest repellers emit 20–40kHz. Your phone hears them. Find out who's running one nearby.

livemicrophone · hi-freq

room size from echo

A clap. The echo returns. Speed of sound + delay = wall distance. Measure a room with just your mic.

Below 20Hz — trucks, trains, building resonance. You feel it but can't hear it. Your phone detects it.

livemicrophone · lo-freq

motion & structural

motion force field

Your acceleration rendered as a live force field. Watch the sensor react to every shake, step, and tilt.

liveaccelerometer

surface material ID

Tap any surface. The vibration ring-down frequency reveals whether it's concrete, wood, glass, or thin metal.

partialaccelerometer

How you walk is as unique as a fingerprint. Walk 10 steps and see your motion signature extracted.

liveaccel · gyro

micro-seismic logger

Leave your phone on the floor overnight. See every footstep and vibration that occurred while you slept.

liveaccelerometer

floor-by-floor altimeter

Your barometer is precise enough to detect each floor of a building. Your altitude is always known.

keystroke timing biometric

Your inter-keystroke delays are a stable biometric. Type a sentence. See your rhythm captured.

livekeyboard events

touch biometric

Touch pressure and contact area are biometrically unique. Your fingertip on glass is a signature.

livetouch events

biometric & body

A model running in your browser infers your emotion, age, gender, and generates a biometric identity hash from your face geometry. No server. No upload. This is the baseline.

livecamera · ML

fingerprint gate

Touch the sensor. See what the browser receives versus what a native app may receive instead. The gap between those two lists is where your privacy lives — or disappears.

livebiometric · WebAuthn

Accelerometer, gyroscope, and microphone as proxies for heart rate, tremor, activity, and breathing. The Internet of Bodies is not a future concept — it is running on the device in your hand.

livemotion · mic · IoB

light & optical

LED flicker detector

Most LEDs flicker at 100/120Hz. Your camera captures it. See which lights in your space are strobing.

screen PWM dimming

Your screen may be strobing to achieve dimming. Point one phone's camera at another to reveal it.

retroreflector finder

Cameras, road signs, cat eyes — all retroreflect. Use flash + camera to reveal them in a dark room.

livecamera · flash

sky polarization

The sky is polarized. Bees navigate by it. Your camera can estimate the sun's position even when it's hidden.

livecamera · compass

LED light quality

Point at a light source. Your camera extracts color temperature, CRI estimate, and blue spike hazard.

the meta layer — what you reveal

your passive telemetry

~200 sensor readings per second, right now. Here's what can be inferred without you touching anything.

surveillanceall sensors

what apps infer from motion

Walking, sleeping, driving, in an elevator. Your motion data tells a complete story. Here's how it's read.

trackingaccel · gyro

network fingerprint

Your connection metadata creates a fingerprint that follows you across sessions and sites.

identitynavigator api

urban canyon detector

GPS degrades in dense cities. The degradation pattern reveals building density. You're always locatable.

livegps accuracy

crowd density sensor

Audio RMS, network congestion, and BLE advertisement count combine to estimate how many people are around you.

livemic · network · ble

font enumeration

80 font probes. No permission. Identifies your OS, region, and whether you use Microsoft Office.

Response times for login indicators can reveal which major services you are logged into — from timing alone.

livefetch timing

the full picture

Everything running simultaneously. This is what your phone generates every second. This is what's collected.

AR · liveeverything

digital fingerprint

device identity

8 passive readings. No permission. No click. Enough to narrow you to 1 in 300,000 users.

livenavigator api

canvas fingerprint

Your GPU renders a hidden scene. The sub-pixel result is a hash that never changes — clearing cookies does nothing.

Your GPU model, driver version, and shader precision are exposed to every website that loads a WebGL canvas.

audio fingerprint

Your speaker hardware produces a unique mathematical signature from a silent oscillator. Volume at zero. Works anyway.

liveaudiocontext

installed voices

The speech voices on your device reveal your OS, region, language packs, and whether IT manages your phone.

Which video formats your hardware supports narrows your device to a handful of models.

Your real local IP address — the one behind your VPN. Every website can extract it in seconds using WebRTC.

identitywebrtc api

Firefox removed this API in 2016 after researchers proved it tracked users who had cleared all cookies.

livebattery api

Your exact free disk space can identify you across sites.

identitystorage api

clipboard access

Any page can silently overwrite your clipboard. One permission dialog and a website can read everything you copy.

liveclipboard api

WebRTC TURN leak

WebRTC exposes your full network topology — local IPs, public IP, and ISP routing — with no permission prompt.
