Staircase Mojo metric is a user-friendly calculator that helps obtain spindle or baluster spacings between newel posts. This app is perfect for those who need even spacings within a specified distance. It is available for Android devices and is licensed as a full version.

Staircase Mojo metric uses your mobile device to obtain the slope angle automatically. You can place your mobile device along the incline of the stairs and register the displayed degrees by conveniently tapping the arrow button provided. The app also allows you to enter the angle manually if you already know it. Once you have entered the angle, measure the diagonal distance between the newel posts along the slope of the stairs and not the horizontal distance.

After filling in the four entry boxes, tap on the "Calculate" button to show the results with a list of spindle positions and spacing widths adjusted for the slope. The app also allows you to tweak the regulation maximum spacing, defaulting at 98mm, to take into account turned spindles with tapering profiles. It is important to note that the underlying algorithm works out the best fit within a millimeter or so. Under certain circumstances, you can adjust the maximum regulation width slightly and recalculate to reduce the number of spindles.
