TremorGauge - Vibration

TremorGauge is 100% software, using your iPhone's built-in accelerometer — no external hardware required. TremorGauge turns your iPhone into a precision vibration meter and pocket seismograph. Built on the iPhone's accelerometer, it measures real-time vibration intensity in mm/s² with a clean color-coded gauge.

KEY FEATURES • Real-time vibration magnitude in mm/s² (millimeters per second squared) • Color-coded gauge: green (still), yellow (light), purple (strong) • Live X / Y / Z axis acceleration values in g • One-tap baseline calibration (subtract ambient noise) • Audible peak alarm with adjustable threshold • Fully offline — no network, no tracking, no ads

USE CASES • Test machine and equipment vibration • Troubleshoot car / vehicle vibration issues • Check building, floor, or furniture stability • Audiophile speaker / driver resonance test • Earthquake awareness • Physics demonstrations

PRO FEATURES (optional subscription) • 30-second rolling history curve with peak markers • 100Hz high-precision sampling mode (5x faster than free) • Persistent baseline that survives app restart • CSV export of full session (timestamp, X, Y, Z, magnitude) • Custom peak alert threshold

LIMITATIONS The iPhone accelerometer is not a laboratory-grade instrument. TremorGauge is designed for relative measurements and general awareness, not for safety, regulatory, or seismic monitoring decisions. For professional applications, use a calibrated piezoelectric or MEMS accelerometer system.

PRIVACY All sensor data is processed locally. No audio, video, or location is collected. No analytics, no ads, no account.
