## Description

Seismograph is a seismograph, vibration meter, and earthquake detector for Android. Read live ground vibration, peak acceleration, and a Richter-style magnitude in seconds.<br><br>Whether you live in a quake zone, monitor machine or structural vibration, or just want to log the next tremor, Seismograph turns your phone into a portable seismic monitor that works fully offline.<br><br>▶ MAIN FEATURES<br>• Live seismogram with a real-time 3-axis waveform<br>• Ground vibration shown in mm/s or g<br>• Richter-style magnitude estimate (Micro to Great)<br>• Peak event log with PGA (peak ground acceleration)<br>• Adjustable sensitivity for your surface<br>• Alarm threshold with audio + vibration alert<br>• Recording and history of past events<br>• Export your readings and event log<br>• Dark mode for night monitoring<br>• Works fully offline, no account required<br><br>▶ HOW TO USE<br>1. Place your phone flat on a solid surface to monitor.<br>2. Tap Calibrate once while the surface is still.<br>3. Watch the live seismogram and vibration gauge.<br>4. Set an alarm threshold to be alerted on strong shaking.<br>5. Review the peak event log with magnitude and PGA.<br><br>▶ WHO USES SEISMOGRAPH<br>• Earthquake-aware residents tracking tremors at home<br>• Engineers checking machine and structural vibration<br>• Curious users logging traffic or construction shaking<br>• Science teachers and students learning seismology<br>• Makers and DIY builders testing rigs and mounts<br><br>Seismograph uses your phone&#39;s built-in accelerometer to estimate ground motion. It is a fun and useful monitoring tool, but it is not a substitute for official seismic networks or professional instruments.
