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. Check out my other construction related apps....BalusterPro for a baluster spacing calculator & TilePro for a simple tile layout tool. ## Key features - Graphical interface for dimension entry - Automatic plotting of stringer points - Step-by-step visual guidance - Imperial and metric measurement support - Eliminates need for framing square - Connect-the-dots cutting method ## Recent user reviews (9 of 9) All indexed reviews: https://appshunter.io/ios/app/stairbuilderpro/id576147785/reviews.md ### 1/5 — Disappointing *2022-06-13, version 1.4* Used to work great. Had the app on all my portable devices. Now it only runs on devices with an M1 chip. Really counter productive, since my version of a less than 1 year old iPhone 13, doesn’t have that chip. The phone is where I need it the most. Developer website links do not work, to report the issue. I’ll be shopping for a new app. Really disappointing as I paid money for this app, you ought to make it work. 😡😡😡😡 ### 5/5 — I love this app. *2021-04-16, version 1.4* This app makes stair layout a breeze. I've used it for years. ### 1/5 — Mr *2015-08-03* Does no more than I can do with pencil and paper in a few minutes ### 1/5 — Disappointed *2015-06-18, version 1.3* 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. ### 5/5 — Stair Builder Pro *2014-04-28, version 1.3* Great all the way. ### 1/5 — Awesome *2013-03-23* Bought this app , easy to use quick an accurate I just love it an also bought baluster pro which is awesome too. Thanks Greg ### 5/5 — Nice *2012-12-24, version 1.0* Intuitive and easy to use...just enter a few parameters and your stringer is instantly layed out. Works well. ### 5/5 — This is cool *2012-12-05, version 1.0* This is a great tool. Easy and intuitive to use even for a novice like me. I like the way it walked me though the layout process step by step...and my stairs turned out great. ### 5/5 — Carpenters rejoice! *2012-11-15, version 1.0* I was impressed by the first app from this developer, BalusterPro, but this one really knocked my socks off. What really makes this tool special is it's use of visuals to guide you through the process one step at a time. You begin by selecting the type of staircase and entering your parameters. What you get is a beautiful layout view complete with animations showing exactly where to mark and cut your board. Magic. If you build staircases of any kind this tool will save you time and help avoid costly mistakes - an absolute must have for carpenters of any skill level. ## Frequently asked questions about StairBuilderPro ### What is StairBuilderPro?
