## Description

iShindo displays earthquake shaking in real time and auto-records seismic events at your set intensity. Auto-captures photos at the start and end of shaking.

iShindo measures earthquake seismic intensity using your iPhone or iPad.

FEATURES
• Seismic intensity measurement based on the JMA (Japan Meteorological Agency) method
• Modified Mercalli Intensity (MMI) measurement
• Spectral Intensity (SI) measurement
• Automatic earthquake event recording and list view
• Photo capture during earthquake events
• iCloud sync across devices (up to 10)

INTENSITY SCALES
• JMA Seismic Intensity Scale (0–7)
• Modified Mercalli Intensity Scale (I–XII)

TECHNOLOGY
Intensity calculations comply with the JMA instrumental intensity method. SI values comply with the MLIT-specified method. Developed with patented technology from joint research with NIED (National Research Institute for Earth Science and Disaster Prevention).

NOTE
Measurements are not from JMA-certified seismometers. Values are "equivalent intensity" for reference only.

REQUIREMENTS
• iOS 16.0 or later
• iPhone 8 / X or later, iPad with iPadOS 16
