iShindo - Seismic Intensity

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
