This app helps employees quickly determine jobsite elevation marks and calculate slopes. It provides target pole-shots based on established instrument height and allows for instant unit conversions between decimal feet, feet and inches, and meters. It aims to reduce errors and save time on construction sites.
Calculate all aspects of a ramp's dimensions, including slope, run, length, and rise. It can also measure the slope of existing surfaces using your device's sensors. Supports various input combinations for flexible calculations.
This app provides real-time elevation data using your device's GPS and a built-in geoid model. It also displays ground elevation from various web services and includes a pressure altimeter for relative altitude measurements. Features include a live map, accuracy estimates, and one-touch screenshots.
This app displays your current location's latitude, longitude, and altitude using GPS. It also provides barometric pressure, water boiling point, and weather information. You can capture photos with location and elevation data, and even get the altitude of any location worldwide.
Easily measure tilt angles with this free protractor app. It displays inclination from 0 to 359 degrees, along with gradient percentages and angles summing to 180 or 360 degrees. Switch to theodolite mode to set a specified angle to zero.
Calculate slope in angle, percentage, or ratio by inputting two sides of a right triangle. This intuitive and easy-to-use application provides the remaining necessary values.
This app provides real-time altitude readings directly from your wrist or mobile device. It offers unit conversion between feet and meters, and can display your current location on a map for iPhone and iPad users.
Measure angles and slopes with your phone's camera. Offers real-time angle display, two measurement modes, and the ability to capture and store measurements.
Transform your device into a versatile set of precision measuring tools. Accurately level any surface, measure roof pitch and angles, and align objects using your camera. Features include a digital protractor, plumb bob, and compass for various construction and DIY tasks.
