Multi Clinometer is a free Android application developed by Physics Software. It includes a 2D spirit level, a 2D clinometer, and a roll & pitch clinometer (inclinometer) that are perfect for measuring the roll and pitch of vehicles, leveling hobby constructions, leveling pictures on the wall, and more. The app can be accurately calibrated without the need for exactly vertical or horizontal surfaces, and it has both analog and digital displays for the clinometers. The resolution of the analog displays can be continuously adjusted using pinch gestures, and you can choose between degrees or tenths of degrees for the digital display.

Multi Clinometer also has an adjustable noise level/time constant, and you can choose any orientation of your phone/tablet as zero for your display. After zeroing, small angle changes can be accurately measured. The app allows you to select portrait or landscape orientation, backgrounds, and colors according to your needs and taste. All settings, including the calibration, are saved when you close the app.

Overall, Multi Clinometer is a comprehensive leveling and measuring tool that is easy to use and highly customizable. If you need to measure angles or level surfaces, this app is definitely worth checking out.
