BulyKid - Handy on the Jobsite
Useful tool to have when walking the job site. Much easier than having to carry a full size calculator. I think $25 is a little more than it should cost personally, but it’s still cheaper than the real calculator. One complaint I have is the App icon looks very dated aside the rest of the apps on my phone. Hopefully that isn’t a sign that it no longer receives updates, or that it will become incompatible with new iOS versions.
Mombo427 - Not the same
I have a handheld that I have used for years. I should have looked at this screen more closely before I downloaded this. We constantly have to convert inches to millimeters and my handheld has a button for both mm and cm. This one does not so just pay attention to what type of calculation you need to do if you are used to using the original. Otherwise it looks like a good unit for most other things.
ConcreteProdigy - Better than the actual calculator
I have been using this calculator for years as a concrete business owner. After breaking and losing so many of these I finally just downloaded the app and boy was I pleased. It's crisper easier to use and honestly going to save me money and heartache when I can't find my Calc. Ty for this
Very satisfied customer
1bdashrlydvdson - Exactly what I wanted
As a carpenter I have used a construction master from foundations to roofs, and everything in between. When I wasn’t wearing my tool pouches I was always running back to the truck to get my calculator. Now it’s always by my side.
classhhher - Problem
Would I be able to get my money back? , at my
Job I’m not able to pull out my phone to use the calculator for some problems, other than that. It would be a great tool!
Samiut25 - Amazing please add the ( MASTER PLUS EZ)
Already bought your calculators they are amazing i love them. But i wish you can make the app of the (Master plus ez) there’s a lot construction out there waiting for the calculator. I am A construction Contractor and i know the calculator is a 💣💥 for subcontractors
gotnospice - Always have it with me!
This is great! And even better then the physical one you can easily get help on a button by long pressing it! Great idea!
Readal - Phone is always on me with this app.
Love this as I always have my phone on me and don't have to carry another calculator all the time. Works great!!!!
MDaltezza - Architect necessity
I use this app daily! Saves me a lot of time and don’t think I could be as efficient without it.
Joeatree - Perfect Calculator
I've used this in the field for years now. It does a great job adding inches together.
jirodriguez - Cannot redownload using family sharing
This app is very expensive and now it was
removed from my family members because they didn’t make the purchase and won’t allow redownload. Fix it please!
Helipilot77 - No Advertising!!
If I am going to pay $25 for an app I certainly don’t want to be advertised too. The calculator is great. I prefer it to the hardware based version because the manual is built in, my rating is based solely on their recent decision to advertise to a paying customer.
lordylords - Good
Needs a back button
briantd - Recently started showing Ads
This is an expensive paid app, and yet I’m now being shown ads. Does the hardware version show ads as well? #fail
Menom86 - Very good app for my iPhone and me love it
Very good app for my iPhone but me and love
rberg76 - Great!
I love it please update for iPhone X 🙏🏻
Riffats44 - $25 app and they run advertizments
$25 app and they run ads; would not buy again. I want a refund
tilehate - Ads
Just paid $25 and as soon as I opened the app I get an advertisement. Sad and very disappointing.
STEVEDEE321 - Bugs !!!
Numbers don’t line up probably on calculator screen !!!
hayden pistole - Explained
I multiplied 1/2 x 3/5 and it gave me 5/8
Tripol'e - Finally the best has arrived on my iPhone 3Gs
I have been using the Construction Master Pro calculator for over 15 years. There is no better device on the market. The day I got my first iPhone I sent an email to Calculated Induatries asking when they would have an iPhone app. They said they were considering it.
Since then I have tried two different apps that alleged to be full function construction calculators. They were wrong. They were not Construction Master Calculators. The last one I was using, and the best of the lot, could not even do direct circle calculations such as simple area and cylinder volumes.
I just found and purchased, for the whopping sum of $9.99, the Construction Master Pro app for my iPhone 3Gs. The best thing I can say about it is that it is exactly like my standalone Construction Master Pro calculator. I can finally stop carrying a seperate calculator when I go to job sites. Thank you Calculated Industries for the best construction calculator on the best smartphone.
cs9900 - Fantastic
As a finish carpenter I've used a CM calc for years. When I got an iPhone a few years back, I immediately looked to see if CI had made an app--I was sad to find they hadn't yet at that point. I used cheaper, less functional constr calc apps for a while, even contacted CI to request a real CM app. They said they were thinking about it. I waited and waited, and bought it when it first came out, using it regularly ever since. I was stoked to find it was very well done, not like so many junky apps out there. The iPad version is great now, also! And having the manual right there at all times makes it even more valuable than the dedicated calculators, not to mention if I have my phone I have my CM! I couldn't be happier!
cdv - Great App!!!
I am an architect and have relied on my Construction Master pro calculator for years in practice. Last year I was about to buy a new one to replace my old one that wasn't functioning properly. I went to the Construction Master Pro website to compare various models and noticed they had one for the iPhone. Which was substantially cheaper than what I was about to pay for a one of the newer models, I might add. I immediately went to iTunes and downloaded it. It has been great having it available whenever I needed it.
Now I am very pleased to see it works natively with the iPad as well. A must have app for professionals and anyone in the construction industry that has to deal with quantities, dimensions, and conversions, etc.
e.gustavo - Absolutely fantastic app!
I love a great calculator and this app is not only a fantastic calculator, but it's also at the top of my list of all time favorite apps. Excellent layout, wonderfully designed functionality, and the prices point is perfect. While I don't work in a construction related field, I am looking to buy a house and I'm constantly typing away at this calculator. I work as a cinematographer and have been finding myself figuring out calculations during pre-production planning of sets and lighting plans. I've recommended this app to numerous production designers and set construction personnel who had no idea it exited. Very happy with my purchase and would highly recommend it to anyone who will listen.
Kbennett81 - Best app ever
I have been a long time user of a Construction Master IV and this app takes everything great about the master iv and makes it better. The ability to hold down a key to get help with a subject is wondeful. No more thumbing through a booklet for answers. It's great to always have my construction calculator with me. I read some reviews where people were complaining about the flash screen while the calculator loads. These people just want something to complain about. The screen is only there for 2 seconds. If you can't wait that long then something is wrong with you. Overall this is the best and most useful app that I have come across.
veryken - Perfect conversion
My physical version died recently after 10 years of constant use. I was searching for a replacement unit, looking at the same physical version selling for the same price as 10 years ago, and was worried about how the cheap circuitry could go bad again. But then discovering this app and using it for a day made me a perfect evangelist. In my iPad in portrait mode, it is truly a superior version. Gives another purpose to my iPad Air. The only minor downsides are no keyboard input and the first tap is always not audible. But trivial complaints. I love it.
Stonebent - Disappointed User of Physical Calculator and App
I have used the actual physical Construction Master Pro for years with no issues. It was essential to my work as a carpenter. The app has been great and in some instances superior to my original calculator. One example would be that I don't need to carry around the little instruction book because it built into the app. Now my app crashes. I needed to get a stud count for some walls and it kept giving me an error. I checked the help section to verify that I was doing it correctly. I was, so I checked the on center spacing and it said zero. Great, no problem, I will just go to preferences and set up the right spacing. Nope, it crashes every time I go into preferences. Please fix!
Carpentry pro - Where is my calc.
I have always had my construction master on me while working. And when I got to my weekend side job last week and realized I had forgot it in my work truck I thought I was in for a long day of chicken scratching. Thank you for creating an exact replica of the calculator as an app you saved me hours of work for a fraction of the price I spent on the many of you calculators I already own.
Adam Schinker - Great alternate when I don't have my CM Pro
I doesn't replace my CM Pro, but is great for quick reference when my CM isn't handy. I wouldn't P&E a whole project with it, but you could if you absolutely needed to. If you need a hard copy of the user guide check out CI's website, it is a better reference than the built in guide. I have used the CM series of calculators for about 15 years and the iPhone version is on par with the physical calculators.
tscibilia - Remove splash screen
Please remove the cmp pro splash screen. I know what I bought and it's a waste of time to wait for it to load when in fact no "loading" is required for the calculator.
I want to get to the calculator fast and promptly!
ukktor - woohoo! five stars for this upgrade!
oh man, finally ipad ready! i have been waiting for this a long time. i have had the original version for iphone and an actual CM Pro calculator, both are great. I've been using them for making furniture and r/c airplanes and my patio. it's a great calculator for a tinkerer like myself. the new ipad version looks great. THANK YOU!
iPrankster - The best General Contractors app out there
For those that give this app a bad review obviously doesn't know how to use an advanced construction calculator such as this one. Has everything you need, from figuring stairs, rafters, concrete yards; EVERYTHING pertaining to building. I've used there stand alone calculators for years, now it's right on my phone.
four61ob - Best app I've bought so far !
I design enviromental equipment that is fitted into existing power plants for a living and I can't tell how many time while walking a site I wished I had my calc with me. This a great find for two reasons, one I always have my iPhone with me and two I can see this in dark areas of the power plant !!!!
Notpitt - Construction calculator
I have been using these for years and now have added it to my phone. This one less item that I need to carry around the job site. As a superintendent, this has become one of my most useful tools. I recommend that all builders to use this.
Akbaize - Nice!
I used to have to carry a contractors calculator - retail $69. Now I have this app - does all the same computations for a fraction of the cost....and I don't have to carry another device. Let's be honest, our phones are with us always :) ..... And I like the quick tips video at initial launch. Very helpful!
Hoghd06 - There is backspace!
People there is backspace. Swipe your finger from left to right on the readout. Try it out and update your reviews so we can get an update. Amazing app love not having to carry around a calc when I know I always have my phone on me. Love this thing great for
All types of construction.
ST Williams - Full Featured app. This is the one.
I have used the handheld device from Calculated Industries for years and this app is perfect. Various conversions, stairs and standard calculations all on your phone. Check out their web site for other versions and compare to meet your needs.
brumars - Great Start - Needs additional buttons
This is a great app for construction professionals, I use the Construction Master IV all of the time. This app is a great value, but needs updating, adding some additional buttons that the IV has - specifically the row of buttons that allow quick conversion to yards from feet, etc.
NickyTech - Construction Master Pro for I Phone...Finally!!!!
I recommended this to Calculated Industries about a year or so ago and finally came to being. As good or better than the hand held calculator unit just a fraction of the cost and now I for sure will have this very useful app with me at all times! Thanks!!!!!
BroBroBaggins - Great tool
I'm not a master builder. The master builder I work for told me to get this app and learn how it works so that I may save him the time of ordering yards of concrete, floor joists and sheeting, rafter lengths, window/door trim packs, etc. From zero to job site hero for only $20. Construction Master has found a way to keep me valuable.
CB GC - Everyday App
There's no questioning this app purchase if you call yourself a builder. The very same as the physical version, why carry two things when you can't even order a pizza from your clunky construction master!!?
TheLupfers - Contractor's Buddy
This is the original construction calculator made into a great app. All the same functions as the four (4) Construction Pro's own and use every day. Calculated Industries is a trusted brand for construction aids and now iPhone apps. Great job.
Now I'll be real impressed if you create a Scale Master and/or DigiRoller app ;-)
Michael V. - Love it!
As a draftsman by trade, I use this app every day at work & it's by far- the best construction calculator out there. Well worth the $20. The normal calculator is $80, so this app is a bargain, and i don't have to carry anything extra when I go to job sites, which is a definite plus.
M11pT - Works Perfectly.
Still own the calculator.
It still works great.
The app has the same functionality and the convenience of it being on my phone.
Totally worth it.
Shweb - Finally!
I have owned this calculator for 10 years. I think I payed about $70 for it. I think this one is better because the instructions are much easier to access. Must have for just about anyone in construction.
Cfunkmike - Love it
I Broke my calculater in my bags. And didn't want to pay 40 bucks again thank you for this calculater it's the same one they sale in home depot but now on my iPhone once again thank you, thank you, thank you
Jonrulesheppner - Saved me money
I need to buy a Constriction master pro for my union apprenticeship classes. Found this app saved me money. As all the keys are the same except for the setting witch are much easier to use. Thanks CM
BNoll - Great app for construction trades!
My iPhone just replaced another device of mine!
This app was something I never thought of, but bought the moment I found it because the physical caculators are so useful.
springer*h-d - The top in Construction Calculations
I have owed a Construction Master Calculator for 10+ years. That calculator help me figure out every job. Now even better I have this App version with me at all times. So good, I gifted the App to my father.
disappointed619 - NO PRO
When I saw this app I was thrilled to have a tool I use all the time on my phone. However it does not have a function a true construction master PRO has which I use often (finding a radius arch in a rise/run condition) making this app more like a construction master IV. I feel I was miss led by this apps title and would not have fished out 20 bucks had I known.

Evaca - Amazing
I feel like I'm cheating! The greatest tool I own .. Its easy enough. Useful examples included. Well done *****
Pickup problems - Too damn good!
If you’re a chippy you must have this, I would have paid $100. It's that good I almost didn't want to tell anyone about it, but I thought I owed it to the makers

Gek025 - Almost perfect.
Been using this app for years and absolutely swear by it. Just recently purchased an Apple Watch and am disappointed that I would have to spend a similar amount on a competitors Calc app to have less functionality. Please add Apple Watch support!
Bluebeep - No freaking way
The first thing this $35 app does is throw an ad in your face as soon as you launch it! Are you freaking kidding me?
I just threw a bunch of money on this Ad-Calc that’s supposed to have some industry reputation?!
That reputation went way down for me the moment I launched it.
Van-liquor - Awesome!!
Works flawlessly. It is exactly like the $110 calculator in the stores. Worth every penny! I’ve used it everyday for years without incident
showbear_hd - Expensive paid app has *advertising*!
After paying ~CDN$35 for the app, the first thing it displays upon opening is a full-screen advertisement for another product that has to be dismissed to use the app. That’s just greedy!
Very negative first impression. Paid apps at this level should have NO advertising at all.
RBirch - Best!
By far the best construction calculator out there! Nice to have all the help options in the app. Would like to see update for ipad with retina though.
Aaronidze - Useful
As a framer I use this app a lot. And it does its job just perfect. For layout, for lumber, for concrete... So what else do you need?
Guessitmator - Estimator
Works just like the hardware version. For a fraction of the cost, I can have it have it on a phone and a tablet and always have it with me.
JDoGinc - Perfect
I work with dirt doing estimates and such finally this app came out it's the same as my calculator i keep in my truck
Binkpear - Good app
Great working app for construction.
D. M. Miller - Shopteacher
Great app. I use it all the time with my students. I've owned the calculator for many years but nice to have it on my phone.
Greenm0nster - Contractor
This is an excellent addition to any toolbox worth every penny. The help button is fantastic.
Eric Nielsen - Construction master
Just as good as my old construction master that I have had for years, and payed $130 for. This app is worth every penny.
Tim0699 - Fantastic!
The best app I have! All the same features of the stand alone calculator for a quarter the price! Nice to always have access to the help too.
jayamundson - worth it
works great i'm a journeyman carpenter never go anywhere without my ipod it's 1 less thing to carry and a fraction of the price of a seperate unit
Armour666 - Worth the price excellent app
I own the physical calculator of the same type and paid $80 for it, the addition of the iPhone version that I always have on me is more than worth the additional cost.
They have been an industry leader with their calculators and the addition of the IPhone app is a welcomed one
Superdrunkard - The Best In Construction Calculators!
I paid a lot more for the physical calculator years ago & what an asset it is. The app is identical & incredibly useful in the world of construction. I would reccomend this app for anyone!

1j2k3h - iPad version
Asked them 2 years ago and a rep said iPad version on the way soon with free upgrade if I purchased the standard one. Obvious she was telling me what I wanted to hear. Never happened. But the app itself is good.
Jarheadjohnson - Freaking awesome app
Best app ever. I have the actuall calculator as well and it's so much nicer just to have it on my phone because I always have my phone on me and whenever I need to us it it's always with me
MrRelo - Great product
Fantastic product, just like the calc I used to carry all the time. Would be great if they would develop Electric Calc Pro for iPhone to have everything on one device.
Mlongbsa - Great App
I used this daily when I worked for a home improvement retail chain to calculate job quantities for customers. Works like a charm and easy to follow instructions if the user forgets formulas.
Bhmartin - Finally
I cracked the screen on my construction master 5 (the only part Not covered by warranty) and was about to buy a new one. I have been waiting for this app forever.
RBacon - Fantastic Product!
This product does it all. Great tool to check plans, make changes on the job-site, calculate rise and run for stairs and even build a custom swingset.
Perfect tool to add to your bag of tricks.
no nickname either - Essential for any Architect's iPhone
I bought my 1st Construction Master calculator in 1994. I have used it on every exam and every project since. What a great surprise to find it now available for the iPhone. Thank you CI!
Nemotarius - Great app for Architects
I have the hand held version of this calculator and find it so handy in my everyday use. I was very happy to see I can have a version on my phone too. Great work CI!
Hammer1970 - Owner
This does not fit my I phone 5 screen. But maybe there will be a update other than that it seems to work just like the real thing
2cutiesMom - Backspace Needed!!
The only thing I would like to see is a backspace. Otherwise I love it.

You won't be disappointed with this purchase.
Rad99004 - The Best Construction Calculator in the Store !
Don't waste your money on the other Calculators. This one does it all .

Developer please consider adding custom button mapping and presets for button layouts.
Next add wizards for guiding a user through common projects.
Thanks Developers !
Package719 - Awsome app!
Perfect for anyone in construction. I use this app every day. These calculators are expensive, can't believe I got it for 10 bucks!

Jbon!! - Jbon
Works great!!! So convenient, I don't have to carry the actual calculator. I can do it straight from my phone. Sweet!!!!
Joimdawoim - Backspace
Worth 2 stars. Since we're not dealing with real buttons here it is way too easy to mistype and having to clear all the input is a real time waster. Gimme backspace I'll give you 2 stars.
rberry61 - The best
This is by far the best app I have on my phone!
Better than the actual $80 calculator.
FlyBoy01 - Wow
I am a home handyman and for the price of this app and what it does, it is well worth it. Thank you CI for having this app!
mjord - Hallelujah!
I'm so glad to find THE dimensional calculator. There are a few others, but they con't compare to CM. Thank you!
Lunajuan29 - Buggy
Since the latest update I've experience crashes and app freezes on 6.0 iPhone 5. Please fix I've used this app for a year already and when I need it it decides not to work as previous versions did
