Precision Leveling Capabilities with Best-in-Class Calibration
Precision Bubble Level is an app that will allow the user to precisely level a surface in 1 or 2 Dimensions. (For example, leveling a work bench, pool table, etc.)
What sets this Bubble Level App apart from other similar apps is the calibration technique and algorythm that allows for the user to confidently be within 1 degree of level! The calibration technique does NOT require the user to find a perfectly level reference surface as is common with other level apps. With this app, any flat, semi-level surface will work for calibrating the device.
The screen will flash when the the level is within 0.1 degree. There is also an option for the app to beep.
