Measure vibrations using phone sensors and display readings on the Richter scale and modified Mercalli intensity scale. Calibrate by placing the device on a flat surface until values stabilize. Check real-time data and reference measurements.
Measure rings and objects using visual cues for accurate sizing. Capture images with the camera and analyze them to determine precise measurements. Save and share measurement results directly.
Measure device dimensions with a ruler tool that displays millimeters and inches. Tap to mark start and end points. Switch between metric and imperial units. Share measurement results directly.
Pupillary distance manually with precise calibration tools. Adjust settings for accurate readings. Save and track measurements over time. Share results with eye care professionals or retailers.
Measures distances using ultrasonic pulses. Users send a sound wave and calculate distance based on echo return time. The displays real-time measurements in inches or centimeters. It works outdoors and indoors for accurate readings.
Measure vibrations and tremors using the phone's built-in seismograph. Track seismic waves and detect earthquakes or volcanic activity. Record and analyze data from body movements or objects.
The app measures distances between map waypoints and surface areas of polygons. Users can select measurement units including kilometers, miles, and nautical miles.
Use camera to measure length, area, angle, or height of objects in real-world environment. Draw objects on surfaces and visualize measurements in augmented reality.
Track and log measurements using Pro and Meter devices. Record data in real-time, view historical logs, and export results. Sync measurements with cloud storage. Set custom units and thresholds. Share data via email or file export.
Measures environmental noise and displays values through a gauge and graph. Shows current noise reference and min/avg/max levels. Allows device-specific calibration. Displays data in multiple formats.
Measure paint thickness with automatic device connection and real-time value display. Detect substrate type and interpret measurement results. Save and share measurement data directly from the smartwatch.
Is a utility that works offline and keeps data local. It includes a live camera feed for CCTV, walkie talkie over local Wi-Fi, compass for direction, and leveler for measuring.
Distances, areas, perimeters, angles, and circle parameters using photos. Define measurement planes in 3D space. Adjust for non-parallel planes. Export measurement data. Share results directly.
