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 T0 FreqCheck is the first ISO/IEC 17025:2017 certified frequency analyzer built for iPhone/iPad, covering the full 1 to 100 Hz spectrum where the most consequential and most contested signals in the world actually live. For scientists, investigators, wellness researchers, and the simply curious — 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. Three input modes handle everything: LIVE — Point your microphone at any source. Spectrum analysis begins the moment you tap (Supports External Mics/DC Coupled Line-In). VIDEO — Select a video file and forensically extract every frequency in its audio track. AUDIO — Select any audio file and audit the actual signal against whatever the content claims. FOR THE MYSTERY HUM INVESTIGATORS If you have heard it, sound that passes through walls and disrupts sleep, you are not alone. Researchers worldwide point to 50-80 Hz as the primary candidate for the "global hum". That range is inside FreqCheck's window, and your iPhone/iPad microphone will easily pick it up the moment it is present. FreqCheck locks the frequency, timestamps it, and generates a sealed report you can share. You knew there was something, FreqCheck tells you exactly what it is. This is not a theory. This is metrology. FOR THE WELLNESS AND FREQUENCY COMMUNITY That track promising binaural beats, brainwave-entrainment frequencies, or therapeutic tones deserves one honest question: is the signal actually there? FreqCheck has that answer in seconds. Brainwave frequencies Delta, Theta, Alpha, Gamma, fall within the 1 to 100 Hz range FreqCheck was built to analyze. If the signal is present, FreqCheck confirms it. If the measurement tells a different story, you will see that too. Replace Blind Trust With Certainty. Precision as easy to use as a measuring tape. 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. ALWAYS FREE. UPGRADE WHEN READY.

Pro unlocks the LOGS vault, full PDF Audit Report export, and community forum posting, where investigators, researchers, and the genuinely curious are already sharing what they have found. 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 1-100Hz infrasonic spectrum visible, measurable, and provable with the device in your hand. You do not need a degree. You need one tap.
