Cool Bubble Level

The building level is a very useful program for managing your smartphone, in case you started repairing your apartment. The program will allow you to align absolutely any heeled surface. As shown in the pictures - the program is extremely idle, but without much effort will replace the real professional levels, which cost a lot of money! To increase the accuracy of the readings - try to calibrate the built-in accelerometer of your smartphone, relative to those planes on which you will make further measurements. This will give you the opportunity to achieve a better result.
