Sonarish
sona, sonarish, sound, local, dsp
Most sound apps are a free dB readout full of ads or a cloud mic that uploads your audio. Sonarish is four acoustic instruments running 100% on-device — the audio pipeline has no internet permission, so it can't upload. Standouts: phone-as-sonar breathing from an inaudible ~19 kHz tone, machine-fault screening (envelope spectrum + spectral kurtosis) normally locked in $2k analyzers, and a calibrated dB(A) meter with timestamped PDF/CSV reports. Hand-written C++ DSP core, native iOS + Android.

Three problems I kept hitting — and couldn't find one honest app for: 1) "Prove it." A neighbor's 1am pounding, or a too-loud workplace, and zero evidence. Every dB app gave me one number, no report, and half of them wanted an account or uploaded my mic audio. Sonarish measures calibrated dB(A) (LAeq, peaks, L10/L90, daily dose) and exports a timestamped PDF/CSV you can actually hand to a landlord, an HOA, or HR. 2) "Is this motor about to die?" A fan/pump/appliance starts sounding off and you don't own a $2k vibration analyzer. Record a healthy baseline once, and Sonarish flags the tone that shouldn't be there (envelope spectrum + spectral kurtosis) — an early warning before it fails. 3) "What's going on while I'm not in the room?" A passive, on-device baby-cry monitor — plus an experimental breathing tracker that reads an inaudible ~19 kHz sonar ping off your chest. No cloud camera streaming your home. What ties it together: everything runs on-device. The audio pipeline has no internet permission — it physically can't upload a recording. Works in airplane mode; check the permission list yourself. Honest bits: it's a screening and measurement aid, not a certified meter or a medical device. Breathing & cry are experimental. Which of the three is your problem? I'll be in the thread all day. 🙏 — [email protected]

Who hunted Sonarish?
Sonarish was hunted by uranashel. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it.
