Moasure ONE is the world’s first motion-measuring tool. An all-in-one compact tool for measuring in 1D, 2D and 3D, diameter, circumference, angles and levels, Moasure ONE measures in 24 different ways just by moving around. This cutting-edge technology is packed into a device that fits in the palm of your hand. Motion-measuring is the technology used in rocket guidance systems to keep track of movement in 3D space. Moasure ONE uses this same technology to take and calculate precise measurements. Using accelerometers, gyros and magnetometers, it plots its three-dimensional position in any space to measure distance, angle, level, and more.
