This app uses your phone's seismograph or seismometer to measure the strength of vibrations, tremors, and earthquakes. It can also detect vibrations from the human body or other objects. You can visualize seismic movements on graphs, get real-time Mercalli scale readings, and receive instant alerts for seismic shocks.
Key features include high-accuracy seismometer readings, seismic wave detection, detailed graphical analysis of movements across three dimensions, real-time Mercalli scale readings, customizable MMI charts, instant alerts for seismic shocks, effortless data autosave in CSV format, comprehensive history access, and Apple Watch compatibility.
The app is available for free with in-app purchases. While the core functionality is accessible without cost, certain advanced features or data management options may require an in-app purchase.
The app is designed to work with smartphones that have a built-in seismograph or accelerometer. It also offers Apple Watch compatibility for seamless control of seismic measurements from your wrist.
Common use cases include monitoring for earthquakes and tremors, measuring vibrations from everyday activities or objects, tracking seismic activities like volcanic eruptions, and analyzing ground motion for scientific or personal interest. It's also useful for spreading awareness by sharing findings.
