From the creator of BalusterPro comes StairBuilderPro, a unique stair stringer layout tool designed specifically for the iPad. Simply enter your dimensions on the graphical interface and StairBuilderPro will plot all of the points on your board needed for a perfectly cut stringer. For advanced users, a single tap will plot all of the points at once or with the step through method, the app will visually walk you through the entire process one step at a time. All there is left to do is connect the dots and cut along these lines. It is that simple. Unlike all the other stair stringer layout guides, there is no need for a framing square, stair gauges or any previous knowledge for building stairs. The only tools you will need are a pencil, tape measure, straight edge and a saw! Works in both imperial and metric measurements.
