Precision Level (software.physics.handylevel) on Google Play
Precision Level is used for accurately leveling horizontal and vertical surfaces. For example leveling a table, a picture on a wall, or the wall itself. Simple and accurate calibration methods are used, such as finding the correct 0° horizontal surface by turning the Handy Level 180°.FeaturesAccurate leveling of horizontal surfaces by a 2D spirit level.Accurate leveling of vertical surfaces by a "sea horizon" level.Accurate leveling of horizontal and vertical surfaces by a 1D spirit level.Simple calibration by a "turn 180°" approach.Adjustable averaging/time constantSelect backgrounds and colors according to need and taste.All settings including the calibration are saved when you close the app.Can also act as inclinometers and shows the angles both analogously and digitally.You can continuously adjust the resolution of the analog displays using pinch gestures.The resolution of the digital display is selectable. Choose either degrees or tenths of degrees.
