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.

Check out the video demo at my website to see StairBuilderPro in action.

Great app

It takes a while to figure a few things out, but a great app. The pattern it gives you is clear to read and also available in PDF for a printer. Only 2 minor complaints....not available for iPhone 4s, and the developer ought to make the measurements reversible so can start the pattern on the right as well as the left or be able to flip the pattern upside down. Definitely top notch.

I am totally disappointed with this app. Once I completed the input and got the layout printout, I proceeded to layout the 2x12. When I got to the end of the board the last riser was way out of wack. I then went back to check all the treads and risers, and noticed the treads were not equal in measurements. Some were 11 1/2 and some were 12 1/2 and one was 11". Soooo, I went back to the old tried and true method of figuring it out myself. My way the stairs came out perfect.... Glad I only wasted 4.99 on this app.
