Reduce the weight of your toolbox – all you need is your smartphone. Also known as a spirit level or buble level – but the name doesn’t matter. What matters is the fact, that with the help of this device you can easily determine whether a given surface is really horizontal. Used by professionals: builders, stonemasons, carpenters, inspectors, metalworkers, but also by ordinary DIY enthusiasts – our spirit level will certainly help you with any home repairs. Our device is based on bull's eye level (also known as circular bubble) which measures the level simultaneously in two dimensions – horizontal and vertical. Netigen Utilities: Level checks not only whether a surface is horizontal, but also shows the angle of inclination. If the surface is horizontal, the ball, shown on the screen, will be in the exact center of the circle and the center will turns white. It works just like a physical device! Ease of use, precision and a unique design distinguish our level, comparing to other similar applications. Recommended for those who appreciate precise tools and job well done.
