Want to ensure that your materials are parallel or perpendicular with each other with the help of this app. Precise Level is a convenient Android app that offers horizontal angle gauge, vertical angle gauge, and bull eye level that enables you to determine the inclination of a surface and get the perfect tilt.

Unlike physical spirit levels, this tool allows for easy calibration to increase the precision of your measurement. You can also extend the time of calculating results to get more stable outputs.

What's more, this app has a save function so you can take note of your measurements, which you can view in the board section.
