The quake meter is an app which uses the seismograph or seismometer in your phone to measure the strength of vibrations, tremors, earthquakes, and even the vibrations of the human body or any other objects around you. - High-Accuracy Seismometer: Detect vibrations from earthquakes to human movements with precision using your phone's built-in seismograph. - Seismic Wave Detection: Track seismic activities like earthquakes and volcanic eruptions using your phone’s accelerometer. - Detailed Graphical Analysis: Visualize seismic movements on graphs, displaying data across three dimensions for in-depth understanding. - Real-Time Mercalli Scale Readings: Get instant updates on ground motion intensity, with average and max values easily accessible. - Customizable MMI Chart: Tailor MMI charts to display seismic data over your chosen time frames for personalized insights. - Instant Alerts for Seismic Shocks: Stay informed with alerts on sudden accelerations or seismic events, keeping you prepared. - Effortless Data Autosave: Automatically save crucial seismic data in CSV format for detailed post-event analysis. - Comprehensive History Access: Review and share your seismic data history, complete with easily accessible CSV files. - Secure Cloud Storage: Safeguard your seismic data in the cloud, accessible on different devices via social accounts or email. - Apple Watch Compatibility: Seamlessly control your seismic measurements from your Apple Watch device, ensuring minimal interference. - Shareable Insights: Capture and share screenshots of your seismic findings with friends, spreading awareness and knowledge. Using the accelerometer in your phone, our app allows you to detect and record seismic waves generated by earthquakes, volcanic eruptions, avalanches and any other sources of seismic activity. Once the activity is measured, the graph feature presents a record of the ground motion at the point of measurement. Any ground movement or object is presented as a function of time along three Cartesian axes, with the z- axis perpendicular to the Earth's surface and the x- and y- axes parallel to the surface. During a span of measurement, you will track average and max values and see current corresponding Mercalli scale descriptions. You can set up your app to display current acceleration, XYZ or Mercalli scale values on the main screen. What’s more, you can find a second chart on the screen with MMI values which can be customized to display different lengths if you want to see shorter or longer time periods. The app allows you to take a screenshot of the whole view to share it with friends. The alerts feature notifies you about sudden acceleration changes or seismic shocks. Go to the settings screen and setup values you want to get notified after. Autosave allows you to save your data when shocks pass through the setup threshold. You can later view the saved CSV file to see the exact measurements during that time. The history screen allows you to see your saved data with date, time, avg, and max values along with a CSV file from the whole span of measurement. You can also share the data as you please. Keep your data safe with our cloud services, which allow you to create accounts and store your data.. Log in using your social media accounts or email to different devices to see and share your data. Our app comes with a brand new application for Apple Watch devices. You can easily control your measurements with your watch without having to touch your phone. Controlling the measurements with the watch avoids interference!
