FreqWatch uses AI to detect and identify the invisible frequencies around you. That 60Hz hum in your house? It's your electrical panel. The high-pitched whine? Your dog can hear it too. FreqWatch tells you what you're actually listening to.
You've heard it. That weird buzz or whine you can't quite place. Existing frequency apps show you a graph of numbers — they measure, but they don't explain. You stare at a spectrum analyzer and still don't know what you're hearing.
FreqWatch changes that. It listens, detects, and tells you what made the sound. Not just the frequency — the source. AI-powered identification built on thousands of real-world frequency signatures.
Full 20Hz – 20kHz audio spectrum, visualized live. Every frequency in your environment, displayed with precision.
Not just numbers. FreqWatch tells you what's producing the frequency — electrical systems, HVAC, insects, appliances, structures.
Build a record of what's in your environment over time. Useful for home inspectors, pest control, building diagnostics.
Get notified when unusual or dangerous frequencies appear — high-frequency noise, abnormal electrical signatures, structural stress.
The human ear hears 20Hz to 20kHz. FreqWatch covers the full range — and identifies what it finds. Electrical grid hum at 60Hz. HVAC systems at 50-120Hz. Pest activity in the 10-20kHz range. Ultrasonic frequencies beyond human hearing that animals respond to.
FreqWatch changes that. The invisible becomes visible, the unknown becomes known. Every hum, buzz, whine, and crack — explained.
FreqWatch. Hear everything. Know why.
