Seismograph: Quake Detector

Find earthquakes near me at a glance - distance and direction to every quake plus a live earthquake map sorted by what's closest to you.

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.
