***Named one of the top 100 new home products for 2011 in This Old House magazine*** BalusterPro is a unique and handy tool designed for carpenters and woodworkers, but useful for do-it-yourselfers and homeowners alike. BalusterPro makes the chore of calculating spacing of handrail balusters a quick and elementary task.  It can also be used for any job requiring equal spacing between boards or slats.  Use for picket fences, bench/chair backs,decking or column flutes. ____________________________________ What users are saying: Punch in staircase and handrail dimensions, choose the configuration, and this app saves you the tedium of calculating baluster spacing. Hallelujah. This Old House Magazine BalusterPro is an awesome app and can be used for a multitude of layout tasks, at your desk, on the job, in your car—wherever your phone goes, and it only costs a few bucks. Gary Katz - Master finish carpenter and publisher of THISiscarpentry.com BalusterPro makes building that stairway more heavenly homefixated.com ____________________________________ Instructions for Use: BalusterPro offers calculations for six different common handrail situations which you may encounter.  First, tap the settings button to select your measurement input method, then select the desired type of baluster installation. Use the keypad or sliders to enter your measurements for ‘Run Length’ (distance between the newel posts) and the ‘Baluster Width.’  Finally, just drag the ‘Balusters Needed’ slider to see your required number of balusters. As you adjust the ‘Balusters Needed’ slider, the “Spacing Between Balusters” will simultaneously update. Stop when your ‘Spacing Between Balusters’ meets your specific code requirements. Tap the view button to see a list of all the centers and edges of the balusters. No longer will you need to keep pressing the add button on your traditional calculator to list your centers....they are all shown on one screen! It’s just that simple! You can display your measurements by selecting 1/16, 1/32, or metric on the main screen to determine your precision level. If desired you can also display your result down to 1/64. To do this, once you have done your calculation, simply tap the 'Spacing Between Balusters' result and if possible it will be further reduced down to 1/64 and displayed for 5 seconds. This is handy if you want to cut all your fillets at once as it nearly eliminates cumulative error. Tap the speak buttons at the bottoms of the list columns to have the app speak your measurements. ____________________________________________________________________ Check out my other construction related apps...StairBuilderPro for a stair stringer layout tool & TilePro for a simple tile layout tool. ____________________________________________________________________ Check out the video demo at my website to see BalusterPro in action.

What if you could take the best construction calculator and fix it. That’s right ... you love it, it has served you well, and you stand by it ... but could it do more? Could it be easier to use? After testing by pros from around the world, BuildCalc is ready to give you more - more function and more answers with less complexity, less hassle, and less confusion. MORE FUNCTIONALITY: • Advanced Baluster Function: Complete layout of railing and staircase balusters with less guess work - and with all the flexibility you need for every custom job. • Advanced Stair function: Stair layouts for professional results - including dimensioned drawings of your Stringer, Stringer Installation, and Finished Staircase. And you can email a PDF of these drawings right from BuildCalc so you can print them or share them. • Fence Function: Give BuildCalc a fence row length and it will tell you how many posts, rails, pickets, and or panels you need. • Interactive Functions: The Stair, Baluster, Compound Miter, and Rafter functions are now fully interactive. Want to change input values? Change the Run? Switch between Regular and Irregular Hip Roof analysis? You can do this and your results will be updated automatically - without you needing to remember what key to press. MORE ANSWERS: • You are no longer tied down to: only one brick, block or tile size for the masonry function; a fixed number of drywall sheet sizes; only one footer cross sectional area; or one size of shingles and sheathing. If you don’t see the size you want, you can add as many as you need. And for area input, you can store your custom sizes in Length x Width format, so you won’t have to do mental gymnastics to figure out what was the dimensions for that last size you stored. • Want to cut your hip roof rafter using a miter saw ... or a circular saw using a hand-held protractor? With a tap of a button, BuildCalc will automatically switch between Miter Saw and Protractor results. BuildCalc can do this for Compound Miters, too. • Sheathing Angles, Purlin Angles, Gable Area, Backing Angles, Plan Angles, Rough vs. Finished Stair Layout Dimensions, Stringer Throat, Stringer installation dimensions ... and a lot more not found on other construction calculators. LESS COMPLEXITY AND LESS HASSLE: • Tired of having to press and press and press buttons to get the results of a calculation? BuildCalc puts an end to this. For all advanced functions, you get ALL of your results in list form with just one or two key taps. • And, rather than having to write down those results, all advanced functions allow you to save your results - as many times as you want with a label you choose - so you can recall the complete results at your convenience. Now you can do a calculation today and two days, two weeks or two years later, it is there for you. • Less “quirks”. Have you been annoyed by arcane key stroke sequences on other construction calculators? We are too. BuildCalc 2.1 streamlined the keystrokes to do a better job of giving you less “errors” and more results. Don’t remember what you have to enter before a Hip Rafter or Stair calculation? Well, now you don’t have to. BuildCalc will provide you with a check list of inputs and on-the-spot help to get it right. • Drywall and Masonry “Room Mode”: If you have stored a Length, Width and Height for a room, BuildCalc will give you the Drywall or Masonry required for the walls and the ceiling / floor - with only a tap of the Drywall or Masonry button. No more pondering over complex key sequences ... it just works. NOW WITH ADVANCED STAIRS, BALUSTER, AND HIP/VALLEY FUNCTIONS Get more results than you ever could before - including dimensioned Stringer, Stringer Installation and Finished Staircase Drawings. Drawings can then be emailed to others or printed at your convenience. Email us and we'll send you an example!
