You've heard it. That low, persistent hum no one else seems to notice. That frequency track promising precise therapeutic tones that may or may not actually be there. That vibration in your chest you cannot explain.
It doesn’t matter what you were told, FreqCheck lets you measure it.
NOW YOU CAN SEE WHAT YOU'RE LISTENING TO
FreqCheck is the first ISO/IEC 17025:2017 calibrated frequency analyzer built for iOS, covering the critical infrasonic and low-frequency spectrum where the most consequential signals in the world actually live. For metrologists, structural engineers, researchers, and investigators — FreqCheck speaks one language: physics.
One tap. See it. Know it. Prove it.
THE MOMENT THE SCREEN COMES ALIVE
At rest, the display is clean and silent. Meters at zero. No false signals.
Then you tap LIVE.
A waveform explodes onto your screen in real time. Precision meters lock instantly. No configuration. No setup. Single-tap activation is the entire workflow.
Multiple input modes handle everything:
* LIVE — Point your internal microphone at any source, or interface elite industrial instrumentation via external DC-coupled line-ins (such as the RogaDAQ) to capture clean telemetry down to 0.5 Hz.
* VIDEO — Select a video file and forensically extract every frequency in its audio track.
* AUDIO — Import professional lossless formats (.wav, .flac, .alac, .aiff, .m4a, and .mp3) to audit the actual physical signal against published claims.
FROM CONSUMER CLARITY TO ENTERPRISE METROLOGY
Powered by the proprietary IND CORE™ Spectral Metrology Engine (protected under U.S. Patent No. 12,659,418 and active continuation application 19/660,467), FreqCheck bridges the gap between everyday field audits and defense-grade instrumentation.
Whether you are tracking the 50–80 Hz mystery "global hum," verifying wellness and binaural frequency tracks, or executing structural resonance and FCC Part 90 compliance monitoring using professional hardware bridges, FreqCheck delivers unmatched computational accuracy.
FORENSIC-GRADE PROOF. IN YOUR POCKET.
Every measurement is sealed by three forensic layers:
* Device-Hash Anchoring — locks data to the verified hardware signature of your specific iPhone/iPad.
* SHA-256 Sealing — mathematically seals the captured data at the moment of report generation.
* Digitally Signed PDF Reports — any alteration after generation fully invalidates the document.
The result is a NIST-traceable PDF Audit Report with the same evidentiary weight as a controlled laboratory result. Certification #05122C9A 2602.
ZERO-KNOWLEDGE PRIVACY & ECOSYSTEM ACCESS
FreqCheck operates on a strict zero-knowledge edge-computing framework. 100% of IND CORE™ signal processing occurs locally on your device; no raw audio or video is ever uploaded or stored. Ad-tracking SDKs have been permanently removed.
* Free: Basic environmental scans with ad-supported reload.
* Remove Ads: $2.99 one-time.
* Pro Analyst Monthly: $19.99 per month with a 7-day free trial.
* Pro Analyst Lifetime: $149.99 one-time.
Pro unlocks the LOGS vault, full PDF Audit Report export, and the Nyquist Forum portal—the world's growing open repository where field teams and investigators share certified, cryptographically sealed telemetry data.
THE MICROSCOPE MOMENT
The microscope did not create bacteria. It revealed what was always there. GPS did not create your location. It made it knowable.
FreqCheck makes the infrasonic spectrum visible, measurable, and provable with the device in your hand.
You do not need a degree. You need one tap.

The Decentralized Laboratory
FreqCheck has already established a new baseline for edge-computing metrology. With this update, we are completely liberating the acoustic laboratory. You no longer need to be tethered to cumbersome rack-mounted analyzers, tangled interfaces, or archaic desktop software to process high-resolution offline telemetry. These latest architectural upgrades reinforce the IND CORE™ as the undisputed standard for infrasonic analysis, making legacy workflows entirely obsolete.
Professional File Ingestion: Process uncompressed and lossless .wav, .flac, .alac, .aiff, .m4a, and .mp3 files directly from your device or iCloud Drive.
Extreme High-Fidelity Support: The engine now effortlessly handles massive audiophile files up to 24-bit / 384 kHz without processor bottlenecking or thermal throttling.
Automated Standardization: All imported media is dynamically aligned to the 44.1 kHz laboratory standard prior to analysis. This ensures absolute mathematical consistency in FFT bin widths and sub-Hz measurements, completely eliminating the scaling drift commonly found in legacy software.
Enterprise-Grade Metrology: Delivering the exact 32,768-point FFT mathematical rigor of traditional hardware, FreqCheck bypasses easily manipulated raw data outputs. Every live measurement and file import is instantly secured with an ISO 17025-aligned, SHA-256 cryptographically sealed PDF report.
