About
Seismograph+ records vibration waveforms in real time using your iPhone's accelerometer, just like a professional seismograph. View 3-axis simultaneous waveforms with Richter and Mercalli scale estimation. Automatic event detection captures vibration spikes with timestamps, while waveform recording lets you save and export data for analysis. Key Features: - Real-time 3-axis seismograph waveform - Richter + Mercalli (MMI) scale display - Automatic vibration event detection - Waveform recording and playback - CSV data export - 3 sensitivity levels (micro/normal/strong) - Vibration alert notifications Perfect for earthquake monitoring, construction vibration tracking, floor vibration recording, and physics education.
