TremorGauge - Vibration
Seismograph · Shake Meter
Only for iPhone
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
iPhone
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.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
This update makes the live gauge easier to read at a glance: unsupported motion states are now shown clearly, and the main screen includes a short reminder about intended use. History, threshold alerts, and export flows also received small polish touches.
