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?

*** I have a lot invested a lot of myself in this app and want it to be the best construction calculator app. IF YOU ENCOUNTER ANY DIFFICULTIES, PLEASE CONTACT ME AT INFO-AT-BUILDCALC.COM - I REALLY WANT TO HELP! ***

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.


• 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


• 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.


• 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.

Best for construction & estimating This product has the most detailed user manual available. There are plenty of other similar construction calculator apps that have plenty of features but are difficult to use. If they are too difficult to use they are a waste of money. Buildcalc has tried to learn from some of the other developers mistakes. This is a excellent app.

Better than Construction Master When I changed from iphone to Android I could not bring over my Construction master app that I had purchased. I know a few fellow contractors that use this app, and they told me it does everything the Cm does... and more. It's true. I've used this app almost everyday for over 6 month. It is all you need, doesn't seem to have any bugs. I highly recommend 5 stars

Sim Ayers

It's a no Brainer The CMC is prehistoric compared to BuildCalc. This is the first app everyone in construction should buy, period. It's a no brainer to use and it has display screens that give you the information to actually build something. The auto generated stair PDF files with your rise, run, stringer layout dimensions sets a new standard for phone/tablet apps. Just brilliant.

Ben Pope

Help for the mathematically challenged I do a lot of home renovation projects and always have a hard time getting the math right. Whenever possible I do things without math, but sometimes it can't be avoided. BuildCalc has greatly improved the quality of my work by helping me estimate materials needs and getting measurements and spacing correct. BuildCalc has a bit of a learning curve, but the documentation does a good job explaining how to use the software.

A Google User

Better than construction master! The only thing that makes this better than CM is ability to email solutions. The radius function brings up a whole separate screen.

A Google User

Couldn't work without it. I'm a carpenter and I love this app. From simple conversions and aiding in estimating to doing stairs and fences this app is well worth the money. Kudos to the developer.

Donald Gianino

Best construction calc update I still don't really have much more to say than I use it everyday at work and it is awsome. Best construction calculator out hand down!

Albert Sawicki

Andre Odore

Best building calc I've used! Highly recommendthis well thought out app.Use it all the time.

A Google User

For now Not so sure yet if it's easier than cmp...will see...

A Google User

Stylin! Probably overbought as I'm in building repair, but just having all tools in that this app has, well worth the money!

Jake Ham

Best I used to use Construction pro, now this is better than any others out there.

Alexander Yee

Efficient, simple, outstanding I have used the cmpro for years but I got a gift card for the play store and bought this. I was skeptical about buildcalc at first but I am amazed how much more in depth it is. I would recommend it to anyone. I only wish it came in an actual calculator form so I don't have to carry my phone on site!

John Hamm

Works great Use it all the time.

A Google User

Top Notch I barely use my Construction Master since Buildcalc. Excellent app!

A Google User

Brilliant Does multitude of complex tasks

Nick Currence

Best Best there is. No doubt about it

John Deen

Automatic rounding I love this app and have used it for years but I discovered that if you type in millions of feet (not millionths) with decimals (is. x,xxx,xxx.XX ft) this app AUTO rounds to the nearest foot! That caused a 5" shift in a structures location without notice. We barely caught it in time! THATS NO GOOD!

ROD Wolodkewitsch

Great calculator The best on the market. Does everything! And then some. Almost too much.

A Google User

buildcalc Best thing out there for anybody in contruction. Look out "Construction Master Pro", new kid on the block! And he's way badder than you!

A Google User

Most needed app Best calculator you can get. $30 cheaper than you can buy in a store and has more functions. Great customer service and updates. Must have.

A Google User

Great program when it loads Had the program for over two months and it does an excellent job in calculating most aspects of framing and other construction projects. Unfortunately, the program seizes up or doesn't load most of the time lately.

A Google User

John Best calculator on the market for remodel and new construction. Stair steps, rails, and balusters become a breeze.

A Google User

Best Construction Calculator!!! I have paid versions of the big players and BuildCalc blows them away with the amount info and ease of use. Seen features of future release, WOW!

A Google User

Did not load

A Google User

Bigweazer Absolutely amazing but why can I use it anymore? I already paid for it once now they want me to pay again??? And again!!!

David Tuttle

First app I install This is the first app I install on a new phone. It is also the first app I purchased when I got my first phone. It is capable of laying out stringers, banister, wainscoting and much more! If you're a carpenter you need this app

Angus Kroll

Best construction calculator app I use this almost every tile job I do!

Ryan O'Toole

Great for the job site If your boss isn't stuck in 1863 and let's you use a cell phone on site, this is perfect

Mike Freeman

Saves my butt everyday. Love this app i am a landscape contractor and i use this for qty's on matirials.

John Deen

Daily Joy I don't find apps often that deserve review, and fewer that are good. BuildCalc is a pleasure to use. They seek to improve their product to benefit their customers. I carry one less device with greater function and with less $$ due to this one app. Thank you guys, absolutely top notch!

John R. Johnston

Great App. Replaced my CM pro with it. What I don't like is that every so often it tells me this is a trial version and I should buy it. I see another review on the site to that regard. What's with that? Haven't seen an update since I bought it either but then neither did CM Pro . Tell me how to get rid of this occasional Nag screen.

K. Matson

Great app, but fails when I need it most I bought this app and it's worth every penny. Unfortunately I get prompted to either pay for the app (which I already did) or exit. Seems to happen every time I'm in front of a potential client too. Contacted developer several times.

Michael Stiller

I get the message i need to buy. I have done so almost a year ago. LG vs890 4g.

L Foley

For now Why do you keep saying unlicensed copy! Arrrg

Ed Odenbach

Great app. Problem with first. Emailed, stated my problem. Fixed in minutes.

Ryan Chaffee

Having trouble with it when I'm in spots that have bad signal. It tells me that I need to purchase it when I have already. Any other time it works fine and think it is the best construction calculator out there.

Albert Sawicki

Best of all others I have been using it on iphone, worked perfect. Now time to switch to samsung!!!!

Joe Loesche

I use this every day. It is better all the other ones.

Pedro Hiebert

It is very good calculator I used it for construction it works good.

A Google User

John Best calculator on the market for remodel and new construction. Stair steps, rails, and balusters become a breeze.

L Foley

For now Thank you for the fix you always deserve 5 stars as long as it keeps working!

Kale Crittenden

Love this app. I recently switched from Apple to Android, this is the first app. I purchased after the switch. I have purchased Build Calc now twice for full price and don't regret it. This is by far the best on the market.

kevin helwig

Journeyman carpenter This app works great. Use it a lot for stairs. Love that it tells you anything you want to know about what each button does and how to use it.

John Muscella
