建物診断が出来る水準器「水平くん」

It is a very useful building diagnosis app made by a building diagnosis expert.
Please use it ♪

Besides being able to measure the level of the floor as a level
Like an infrared laser leveler with a camera
You can also measure the verticality of the wall.

Both the angle and the slope are displayed for building diagnosis.
There is also a zero correction function, so if you can perform zero correction firmly,
I think that you can measure the slope accurately for your smartphone.
