TremorGauge is 100% software, using your iPhone's built-in accelerometer β€” no external hardware required. TremorGauge turns your iPhone into a real-time vibration reference meter for relative equipment and surface checks. Built on the iPhone accelerometer, it estimates vibration intensity in mm/sΒ² with a clean color-coded gauge. KEY FEATURES β€’ Real-time vibration magnitude in mm/sΒ² (millimeters per second squared) β€’ Color-coded gauge: green (still), yellow (light), purple (strong) β€’ Live X / Y / Z axis acceleration values in g β€’ One-tap baseline calibration (subtract ambient noise) β€’ Audible peak alarm with adjustable threshold β€’ Fully offline β€” no network, no tracking, no ads USE CASES β€’ Test machine and equipment vibration β€’ Troubleshoot car / vehicle vibration issues β€’ Compare floor, desk, or furniture vibration changes β€’ Audiophile speaker / driver resonance test β€’ Relative shake awareness β€’ Physics demonstrations PRO FEATURES (optional subscription) β€’ 30-second rolling history curve with peak markers β€’ 100Hz higher-rate sampling mode (5x faster than free) β€’ Persistent baseline that survives app restart β€’ CSV export of full session (timestamp, X, Y, Z, magnitude) β€’ 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 risk-monitoring decisions. For calibrated work, use a dedicated piezoelectric or MEMS accelerometer system. PRIVACY All sensor data is processed locally. No audio, video, or location is collected.
