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 nine months of development and testing by pros from around the world, BuildCalc for Android 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, Diagonal and Hip/Valley 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.
• New Full Daylight Visibility Mode


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 so you can recall the complete results at your convenience.
• Less “quirks”. Have you been annoyed by arcane key stroke sequences on other construction calculators? We are too. BuildCalc 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.
• Full Construction Master® Pro emulation. BuildCalc is in no way affiliated with Calculated Industries, owners of the Construction Master trademark.

Absolutely the best construction calculator available.. I have been in the business for a long, time and have tried so many other construction apps but were definitely not the go to one always had my doubts with them and could be costly.. But you certainly won't have that in this app. Has a low learning curve nice flow as well a intuitive UI. It will be the best change you ever spent literally for what you get from it... good luck.

I have used this app for approximately 6 years on a daily basis. Everything about this app is outstanding including exceptional customer service from the developer. The only issue that I have had is transferring the app between upgraded phones. Their customer service resolved the issue in less than 24 hours. I would highly recommend this app to anyone in the construction or woodworking industry!!

Construction master pro shut my app down with a paywall after I had purchased the pro version over a decade ago. My pro subscription info didn't transfer to my new phone, and I was unwilling to spend the time to try and find my original order to prove my purchase. I went to purchase it again when I realized they wanted 40 bucks a year for a subscription, no thanks. This app functions great in my initial testing, and I liked the developers' comments, so I gave them my money instead.

I can tell you with confidence, just with my limited do-it-yourself experience, that this calculator easy to use and extremely user friendly. If you are unsure about a key, just hold it down and an explanation pops up. There is also a full pdf manual to peruse. Some of the more complicated calculations are determined through visual representations of what you are trying to calculate and areas to enter their values. I could go on. Bottom line, this calculator is worth it! Cheers

Update: Dec 24th 2021 - Still one of my most used and valued apps. I was looking to transfer my purchase to a new email for professional purposes, and Ben, the developer, went way above and beyond in helping me find a solution. He was quick to respond and very thorough in his email. Old review: If your boss isn't stuck in 1863 and lets you use a cell phone on site, this is perfect

I have been using this app since my iPhone 3G. It will always be on any phone I own. I had zero qualms about paying again when I switched to Android. Now, as I start my own business I will buy again on the company account without batting an eye. The dev is responsive should you run into the occasional technical snag too. They have been reliably churning out updates for as long as I have used the app. For nearly 15 years.

I've been using this fantastic app on my phones for almost 10 years with few complaints if any. The developer is accessible and open to ideas and input. After spending hundreds of dollars on the other guys for years and always being disappointed, this came along and changed the game. I highly recommend this BuildCalc app to any contractor who needs to save time and money. The best tool in my toolbox.

I've been building 40 plus years. This is one of my favorite tools in my business and as a professional carpenter. You might say it is the "Festool" of the carpenters app world. Do not hesitate to purchase this app, it is the best, stable, and personally well suported by the owner, answers immediately. I am eagerly waiting for the desktop version! Thank you "BuildCalc"!
