TremorGauge - Vibration

TremorGauge is 100% software, using your iPhone's built-in accelerometer — 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/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
• Compare floor, desk, or furniture vibration changes
• Audiophile speaker / driver resonance test
• Relative shake awareness
• Physics demonstrations

PRO FEATURES (optional subscription)
• 30-second rolling history curve with peak markers
• 100Hz higher-rate 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 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. No analytics, no ads, no account.
