Construction Master Pro Positive Reviews
Handy on the JobsiteUseful 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..Version: 10.7.0
Not the sameI 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..Version: 1.1.1
Better than the actual calculatorI 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.Version: 1.5.0
Exactly what I wantedAs 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..Version: 1.5.1

Finally the best has arrived on my iPhone 3GsI 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..Version: 0
FantasticAs 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!.Version: 1.2.0
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..Version: 1.2.0
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..Version: 0
Best app everI 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..Version: 0
Perfect conversionMy 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..Version: 1.4.1
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..Version: 1.2.0
Great alternate when I don't have my CM ProI 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..Version: 0
Remove splash screenPlease 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!.Version: 0
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!.Version: 1.2.0
The best General Contractors app out thereFor 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..Version: 0
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 !!!!.Version: 0
Construction calculatorI 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..Version: 1.3.0
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. .Version: 0
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!.Version: 1.3.5
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..Version: 1.1.1
Great Start - Needs additional buttonsThis 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..Version: 0
Great toolI'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..Version: 1.3.5
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!!!!!.Version: 0
Everyday AppThere'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!!?.Version: 1.3.5
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..Version: 1.2.0
Contractor's BuddyThis 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 ;-).Version: 0
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..Version: 0

Worth the price excellent appI 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.
