The Inclinometer is a very simple yet accurate slope measurement tool that offers a dual, analog and digital, display of the data acquired from the mobile device's sensors. To measure the inclination of a surface or plane, all you have to do is to align your phone or tablet along with the surface. If the device is in a perfectly horizontal position, our app will normally indicate zero (0.0°) for the roll and pitch about the X and respective Y-axis. With one decimal place, the measurement's accuracy is one-tenth of a degree (0.1°). If the readings for a horizontal surface are not zero, they can be automatically adjusted by using a straightforward Calibration procedure. Moreover, our app includes a large, easy-to-use compass with optional black or white dials that shows the true north direction and the corresponding numerical values for azimuth and declination. A tap anywhere on the dials will show an extra menu that allows you, among other things, to save the current values of the measured angles. Key features - text-to-speech option (set your speech engine to English) - pause buttons for roll and pitch, and also compass dials - alerts with sounds and vibrations - special software optimization to lower the power consumption - option to show the sign of the angles - simple commands and ergonomic interface - large, high-contrast numbers and indicators - no intrusive ads, no interruptions - white and black dials for both tools
