Fast Earthquake Alarm

Paid iPhone seismograph alarm for nighttime shaking detection.

Fast Earthquake Alarm is now focused on one job: a paid nighttime seismograph alarm for your iPhone. It uses the motion sensors on your device to monitor shaking locally 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 seismograph. The app does not require sign-in, cloud alerts, social features, or a backend feed.
