Vibration - Seismograph Meter

Earthquake Detector & Monitor

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Turn your iPhone into a professional seismograph. Vibration detects and records real-time vibrations, earthquakes, and seismic activity using your device's built-in accelerometer — no extra hardware needed. Whether you're monitoring earthquake tremors, testing building stability, tracking machinery vibrations, or simply curious about the invisible forces around you, Vibration gives you laboratory-grade measurement tools in your pocket. REAL-TIME SEISMOGRAPH Watch vibrations unfold live on a beautiful waveform display. Three color-coded lines track motion along the X, Y, and Z axes at 100 samples per second — the same principle used by professional seismometers worldwide. Pinch to zoom, toggle individual axes, and observe even the subtlest movements. INSTANT INTENSITY ANALYSIS Every vibration is automatically classified using the USGS Instrumental Intensity Scale, mapped to the Modified Mercalli Scale (I through XII). A dynamic gauge shows your current intensity level in real time, so you always know exactly how strong the shaking is — from "Not Felt" to "Catastrophic." RECORD & EXPORT Tap Record to capture vibration sessions. Every recording saves the full waveform along with key statistics: peak acceleration, RMS level, duration, and maximum Mercalli intensity. Export any recording as a CSV file to analyze in Excel, Google Sheets, or professional engineering software. MEASUREMENT DASHBOARD • Live X, Y, Z acceleration values displayed in g-force • Combined magnitude calculation: √(x² + y² + z²) • Running Peak and RMS readings for sustained vibration analysis • One-tap reset to start fresh measurements SAVED RECORDINGS LIBRARY All your recordings are stored locally on your device. Browse by date, review the full waveform chart, compare statistics, and share results with colleagues or friends. SEISMIC REFERENCE GUIDE Learn about the Mercalli Intensity Scale with a complete reference for all 12 levels — from Level I (Instrumental) to Level XII (Catastrophic). Understand how acceleration maps to real-world effects, and follow calibration tips for the most accurate readings. BUILT FOR PROFESSIONALS & ENTHUSIASTS • Structural engineers testing floor and building vibrations • Construction teams monitoring equipment impact • Homeowners tracking vibrations from traffic or nearby work • Students and educators exploring physics and seismology • Anyone curious about earthquakes and ground motion TECHNICAL HIGHLIGHTS • 100 Hz sampling rate for high-fidelity measurement • CoreMotion device motion with automatic gravity subtraction • Optimized for minimal battery drain • Works on all iPhones — no permissions required • Beautiful dark interface designed for clarity Vibration is lightweight, private, and works entirely offline. Just pure, precise vibration measurement. Download Vibration and start measuring the world around you.
