The Instrument That Changes Everything

"We don't guess at frequencies. We prove them."

A Seismic Shift Is Happening Right Now — And It Fits in Your Pocket

There are moments in history when a single invention quietly, irrevocably changes the world — not with a bang, but with the sudden, breathtaking clarity of a veil being lifted.

The microscope did it first. It revealed an entire invisible universe teeming with life that had always been there, always surrounding us, always inside us — and humanity was never the same. The oscilloscope did it next, making the raw, wild energy of electricity visible to human eyes for the very first time — transforming an invisible, almost mystical force into something engineers could see, shape, and command. Radar changed warfare, weather forecasting, and aviation forever by bouncing invisible energy waves off the world and reading what came back — turning darkness and distance and weather and the night sky itself into a readable, navigable map. And GPS did something even more intimate — it reached down from space and handed every single person on Earth the ability to know exactly where they stood on the planet, at any moment, for free.

Every one of these inventions shared a single defining characteristic:

They made the invisible, visible. They made the unknowable, knowable. And they placed that knowledge — that formerly gatekept, elite, expensive knowledge — into the hands of everyone.

FreqCheck™ is that moment. Again. And this time, it's the frequency spectrum itself that gets illuminated.

Right now, today, an entire dimension of reality — the sub-audible, the infrasonic, the neural, the electromagnetic — moves invisibly through your body, your home, your city, and the digital content you consume every single day. And just like the pre-microscope world had no idea what was living in a drop of pond water, and the pre-radar world had no idea what was moving through the sky above them — the world has had no idea what frequencies have been moving through them, around them, and embedded in the media they trust.

That era of invisible unknowing ends now.

FreqCheck™ is that moment.

FreqCheck™ is a revolutionary iOS application for iPhone and iPad that places a fully calibrated, forensic-grade, NIST-traceable frequency measurement laboratory — the kind that lives behind locked university doors and government research facilities — directly into the palm of your hand.

This is not hyperbole. This is a technology event.

What Is FreqCheck™, Really?

At its heart, FreqCheck™ is the world's first consumer-accessible instrument powered by proprietary Infrasonic Neural Detector (IND™) technology — a measurement engine so sophisticated, so precisely engineered, that it achieves something the scientific and academic community will immediately recognize as extraordinary:

ISO/IEC 17025:2017 Certified accuracy. NIST-traceable results. On a smartphone.

The international standard ISO/IEC 17025:2017 is the gold standard of laboratory measurement competence. It is the benchmark used by aerospace engineers testing jet engines, structural metrologists monitoring bridge integrity, and government laboratories calibrating the instruments that calibrate everything else. FreqCheck brings this standard out of the lab and into the world — not as an approximation, not as a "close enough for consumers" compromise — but fully and authentically.

The IND™ engine doesn't just listen to the world. It interrogates it. It performs real-time Fast Fourier Transform (FFT) spectral decomposition, adaptive noise cancellation, Hanning-windowed signal segmentation to eliminate spectral leakage, and root-mean-square amplitude normalization — all simultaneously, all in real time, all on a device that fits in your shirt pocket.

For the scientist: you know exactly what this means.

For everyone else: FreqCheck sees frequencies that nothing else in your life can see, and it proves — with cryptographic certainty — exactly what it found.

The Truth About What You've Been Hearing Online

Here is something extraordinary to consider.

An enormous, multi-billion-view industry has grown around specific audio frequencies — tones purported to be precisely 40 Hz, 10 Hz, 5 Hz, specific binaural beat targets — promising everything from enhanced focus to cellular healing. These videos accumulate tens of millions of views. They are trusted. They are shared. They are listened to by people who genuinely believe in what they are doing for their health and consciousness.

But what if the signal isn't actually there?

On the FreqCheck™ homepage, you will find a simple, devastating demonstration. A professional tone generator website — the kind used by audio engineers — is set to generate a perfect, continuous 40 Hz tone. FreqCheck™ is opened. The result appears on screen instantly: a precise, stable, verified 40.0 Hz readout. Clean. Confirmed. Logged. Cryptographically sealed.

This is what real frequency verification looks like.

We have also published — on the technical verification page — a screen-captured analysis of a legitimate, multi-frequency sweep from 1 Hz to 100 Hz sourced from a YouTube video. FreqCheck™ sees, identifies, and logs every single frequency in that sweep without exception. Which definitively answers the question of whether streaming platforms filter or eliminate such frequencies before they reach your ears and your analyzer.

They do not. FreqCheck finds them all — when they are actually there.

We will let you draw your own conclusions about what FreqCheck might find — or rather, not find — when pointed at the content the internet has been consuming by the billions. We audit the signal. Not the listener.

At FreqCheck, our philosophy is simple and profound:

"We audit the Signal, not the Listener.”

We make no judgment about what you choose to listen to or why. We simply provide an instrument of unimpeachable accuracy so that for the first time in history, you can know what is actually in the audio you are consuming. The implications of that capability — for wellness practitioners, researchers, content creators, and curious individuals everywhere — are staggering.

The industry now has a mirror. What it reflects is up to the signal itself.

The Interface: Science Made Breathtakingly Visible

You do not need an engineering background to use FreqCheck™. The entire philosophy of its design is that the most sophisticated measurement technology in the world should be as intuitive as looking at a thermometer.

Dynamic Living Waveforms Raw acoustic and electrical energy unfolds across your screen in real time. The visualizer processes complex spectral data — multiple simultaneous frequency components, amplitude relationships, temporal patterns — and renders them as an organic, responsive visual that reacts to every nuance of the signal environment in real time. It is simultaneously one of the most scientifically rigorous and visually captivating interfaces ever created for a measurement instrument. The waveform doesn't just display data — it breathes. It moves with the living, flowing mathematics of the physical world around you. High frame-rate rendering makes it as smooth and immediate as watching water.

Precision Dual Metering Crystal-clear analog-style and digital meters give you instantaneous frequency and amplitude readout. If you can read the speedometer on your car, you can read FreqCheck™.

The invisible world doesn't just become measurable with FreqCheck™. It becomes visible. And it is extraordinary to behold.

Signal Inputs: FreqCheck™ Meets the World Wherever It Is

FreqCheck™ is engineered to accept signal input from virtually any source, making it the most versatile measurement platform ever created for a consumer device.

🎙 Built-In Microphone
Open the app. Point it at the world. Begin measuring instantly. The internal microphone of modern iPhones is a remarkably capable sensor for general acoustic analysis across the audible and near-infrasonic spectrum — perfect for environmental surveys, structural resonance checks, and locating mystery noise sources in your home or workplace.

📁 Imported Media — Video & Audio Files
This capability is, frankly, world-changing. Any video or audio file — a screen recording, a downloaded audio track, an exported clip from any source — can be imported directly into FreqCheck™ and subjected to full forensic spectral analysis. The IND™ engine dissects every frequency component present in the recording with laboratory precision. You can now analyze the actual frequency content of any digital media you have access to, and generate a cryptographically sealed, tamper-evident report of exactly what was — and was not — present in that file.

🎤 External Microphones
Any Lightning or USB-C compatible professional microphone connects directly to FreqCheck™, bypassing internal processing limitations and extending measurement capability for field research, acoustic engineering, and high-fidelity environmental monitoring.

⚡ Direct Electrical Injection — DC-Coupled Inputs
This is where FreqCheck™ achieves its most extraordinary capability.

By connecting a DC-Coupled audio interface — a professional tool used to route raw electrical voltage rather than acoustic signal — you eliminate all audio filtering entirely. The raw, unprocessed electrical signal feeds directly into the IND™ engine. The result: absolute precision measurement capability down to 0.5 Hz. Half a cycle per second. The realm of deep infrasound, seismic activity, brainwave frequencies, and sub-audible physiological phenomena that no consumer device has ever been able to access — until now.

This is the same frequency range used by seismological monitoring stations. By the world's most advanced EEG neuroscience laboratories. By geological survey instruments. FreqCheck™ operates in this range, on your iPhone, today.

What FreqCheck™ Can Detect — A Universe of Application

Because FreqCheck™ measures continuously from 0.5 Hz through the full audible spectrum, its application space is, without exaggeration, practically infinite. Here are the domains where it is already changing the game:

🌍 Environmental & Geological Monitoring
Seismic & Tectonic Activity The earth speaks in infrasound before it shakes. The deep, low-frequency rumble of tectonic movement — the kind that precedes earthquakes — exists in the sub-10 Hz range. With appropriate sensors connected via DC-coupled input, FreqCheck™ becomes a pocket seismological station.
Volcanic Signatures The movement of magma generates distinctive deep infrasonic acoustic signatures. Geological researchers, adventure scientists, and field volcanologists can now carry calibrated measurement capability into environments where laboratory equipment was never an option.
Atmospheric & Meteorological Phenomena Severe weather, lightning-generating thunderstorms, jet stream interactions, and atmospheric pressure anomalies all generate measurable low-frequency acoustic signatures. FreqCheck™ can detect and document these invisible atmospheric events in real time.

🏗 Structural & Industrial Engineering
Critical Infrastructure Monitoring Every structure has a natural resonant frequency — bridges, skyscrapers, dams, tunnels. When that resonant frequency shifts, it can indicate hidden structural damage developing invisibly within the material. FreqCheck™ paired with appropriate sensors provides field-deployable structural health monitoring that previously required a dedicated engineering survey team.
Aviation & Aerospace Sub-audible mechanical vibration signatures in jet engines and airframe structures carry enormous diagnostic information. Experienced aviation maintenance professionals can now conduct preliminary vibrational health assessments with a device that fits in a uniform pocket.
Industrial Machinery Health Rotating equipment — turbines, compressors, pumps, generators — announces its own degradation through changing vibrational frequency signatures, often long before a catastrophic failure occurs. FreqCheck™ delivers real-time vibrational health monitoring on the factory floor without requiring a cart-mounted analyzer.

🧠 Human Physiology & Neural Frequency Monitoring
This may be FreqCheck™'s most profound frontier.
The human brain operates in discrete, well-documented frequency bands:

These frequency ranges are precisely where the IND™ engine operates with full calibrated precision. When paired with appropriate consumer or professional EEG sensors via DC-coupled or USB-C input, FreqCheck™ can provide accurate, real-time brainwave frequency analysis — democratizing neuroscience in a way that has never existed before.

Biofeedback. Cognitive monitoring. Sleep science. Neural entrainment verification. These have lived in hospital neurology departments and university research labs. FreqCheck™ is bringing them into homes, wellness centers, and the hands of pioneering researchers worldwide.

We audit the signal, not the listener.

🔍 Forensic Audio & Media Analysis
Perhaps the most immediately impactful application for the broadest population.
Acoustic Investigations Mysterious low-frequency hums that neighbors can't explain, that city inspectors can't find with standard decibel meters, that cause sleep disruption and physiological stress — these exist, they are often infrasonic, and they have sources. FreqCheck™ is the instrument that finds them.
Forensic Media Authentication Any audio or video file can be imported and forensically analyzed. What frequencies are actually present? What is the signal-to-noise profile? Does the content contain what it claims to contain? FreqCheck™ answers these questions with laboratory-grade precision and generates a cryptographically sealed report as legal and forensic evidence.

The era of unverified audio claims in digital media has an expiration date. It expires with FreqCheck™.

The Three-Layer Forensic Integrity Architecture — Making Data Bulletproof

When FreqCheck™ captures a measurement, it doesn't just record data. It creates a legally defensible, forensically tamper-evident, cryptographically sealed measurement artifact — the kind of documentation that holds up in academic peer review, regulatory proceedings, engineering liability cases, and courts of law.

This is made possible by our proprietary Three-Layer Integrity Architecture:

Layer 1 — Device-Hash Anchoring
The measurement report permanently and irrevocably records the unique hardware signature of the specific iPhone or iPad that performed the measurement. The instrument and the data are cryptographically married. You always know exactly which device produced which result.

Layer 2 — SHA-256 Cryptographic Sealing
At the precise moment of report generation, every data point — every frequency value, every amplitude measurement, every timestamp, every waveform sample — is mathematically sealed using SHA-256 cryptographic hashing. This is the same class of cryptographic security used to protect banking transactions and blockchain records. The data cannot be altered without breaking the seal.

Layer 3 — Digitally Signed PDF Export
The final exported report is a professionally formatted, cryptographically signed PDF document. If any value, graph, timestamp, or data point in that document is altered by even a single digit after generation, the forensic checksum immediately and irrefutably indicates tampering.

This is how FreqCheck™ transforms a smartphone into a forensic instrument. The data it produces is not just accurate — it is provably, demonstrably, cryptographically accurate. For the academic community, for regulatory bodies, for legal proceedings, and for the future of credible measurement science, this changes everything.

The Blue Ocean — A Technology That Creates Its Own World

In competitive strategy, a "Red Ocean" is a marketplace crowded with competitors fighting over existing demand — existing products, existing categories, incremental improvements. The water runs red with competition.

A "Blue Ocean" is different. A Blue Ocean technology doesn't compete — it creates. It opens an entirely new category of value where no competition exists, because no one else has ever sailed these waters.

FreqCheck™ is Blue Ocean technology in its purest form.

There is no other product that does what FreqCheck™ does. There is no competitive category to enter. There is no incumbent to displace. FreqCheck™ has created a new ocean — one where forensic-grade, NIST-traceable, ISO/IEC 17025:2017 compliant measurement capability lives in a consumer application, accessible to every curious person on Earth.

And here is what makes this Blue Ocean particularly extraordinary:
The software is ready. The hardware hasn't caught up yet.

The IND™ engine within FreqCheck™ is so technically advanced — its measurement capabilities so precise, its frequency range so vast — that the consumer hardware industry is currently building to catch up to it. FreqCheck™ has laid the software foundation for an entirely new hardware ecosystem that doesn't yet fully exist.

We are watching it being born.

🎧 The Wearable Neuroscience Revolution An affordable EEG headband that plugs into your iPhone via USB-C. FreqCheck™ already speaks this language fluently. The moment that hardware exists at consumer price points, millions of people will be able to monitor their own brainwave activity in real time — no hospital required. No neurology appointment. No $50,000 clinical EEG system.

📡 Next-Generation Consumer Sensors DC-coupled seismic sensors. Consumer-grade infrasonic microphones. Piezoelectric vibration monitors designed for plug-and-play integration. Structural resonance detectors. The sensor hardware revolution is coming — and FreqCheck™ is already waiting for it, calibrated and ready.

🔬 Citizen Science at Scale When anyone with an iPhone has access to a NIST-traceable measurement laboratory, the nature of scientific data collection transforms. Distributed environmental monitoring networks. Citizen seismology. Community acoustic health mapping. Peer-verifiable biofeedback research. FreqCheck™ doesn't just enable these possibilities — it makes them inevitable.

The software is ready today. The world is catching up.

The FreqCheck™ Horizon — What Is Coming Next

FreqCheck™ as it exists today is transformative. What it is becoming is the foundation of a measurement and cognitive defense ecosystem unlike anything the world has ever seen.

The capabilities encoded within the IND™ technology extend into domains that are simultaneously the frontier of consumer neuroscience, digital media authentication, and personal cognitive sovereignty. The signal analysis architecture at FreqCheck's core was designed not merely to measure the physical world — but to protect the people living in it.

The future of FreqCheck™ includes capabilities that will allow individuals to understand, verify, and defend against the invisible signals embedded in the digital media environment they inhabit every day — signals operating at the precise frequencies that the human brain uses to think, rest, focus, and feel.

The details of this coming evolution are being finalized through a formal intellectual property process. What we can tell you is this: the architecture is built. The science is validated. The precedent is being established.

FreqCheck™ is not the product of a moment. It is the beginning of a movement.

For Every Person Who Has Ever Wondered About the Invisible World

You don't need to understand Fast Fourier Transforms to understand what FreqCheck™ means for you.
