Lengths and angles using a digital ruler and protractor. Detect tilt, pressure, and metal with built-in sensors. Calculate distances and heights with realistic calibration. Sync measurements across devices and export data for analysis.
Calculate gas piping system sizes for low-pressure applications. Input total flow, pressure drop, diameter, or velocity. Output exact and nominal diameters, calculated velocity, and total equivalent length.
Measure colors in XYZ and Lab color spaces from any photo area. Calculate distance between two colors in Lab. Adjust chromaticity values to match iPhone4 camera characteristics. Supports calibration using color checkers.
