In a world with so many objects lying on a horizontal or vertical surface, how easy it is to find a tool that works like its physical equivalent. In fact, when you need to check if a surface is flat, you have to take a number of measurements. The problem is that it is hard to measure the same surface more than once, and even if you do, it will not be accurate enough.

For this reason, the perfect level tool is an easy-to-use tool that allows you to measure the inclination of any object on a flat surface. The application is designed to make your life easier. It is very useful for carpenters, bricklayers, metalworkers, surveyors, and other building trades workers.
