Fast Earthquake Alarm

Detect nighttime shaking, follow recent quakes, and check loved ones from one app.

Fast Earthquake Alarm combines nighttime shaking detection, live quake tracking, regional alerts, and a safety network for loved ones. Using your iPhone's motion sensors, it monitors shaking on-device and helps wake you with a loud alarm and brighter screen when movement crosses your chosen threshold.

Before sleep, place your phone on a flat, stable surface near your bed, adjust sensitivity, and start the detector. During the day, use the same app to follow recent quakes, narrow the feed to your regions, and check safety updates after an event.
