Construction Master Pro Calc App Comments & Reviews

Construction Master Pro Calc Positive Reviews

Construction calculatorI found the original construction calculator at least 15 to 20 years ago. I have used them ever since that time, I have always had a couple in my truck one in the office one of my briefcase and several of them I have dropped broken over the years and had to replace. When I was looking to buy another new one I saw that they had the app online and now with it having it on my phone I have two on my desk there’s none in my truck there’s none in my briefcase it all works right off the phone and I haven’t broken it once. If you are in construction of any kind you should have this app on your phone..Version: 10.9.3

Great calculatorHave used my desktop model for 30 years and couldn’t live without it until this app. Although the giant desktop is great for crunching numbers at home I always use the app on the job site. A bit pricey but worth it if you want an in depth construction calculator and especially if you are already familiar with the format of the non virtual model. Have no regrets about buying..Version: 10.9.1

Great purchaseI’ve bought this actual calculator several times and had to replace it because I lost it or drove over it. Then I bought the app, and it is always in your pocket and an essential tool to have no matter what kind of construction you do. I currently still own one of the real calculators, but I use the app everyday..Version: 10.9.1

Was a good deal with app purchase till updateWas a great tool with a simple one time fee till the last update . Now I get the pleasure of having to login in to apple each time I use it cause they decided to make it a subscription . Sorry I’d use my real construction master over that any day of the week . I would like this fixed but I’m sure it’s gonna take a long time . I’ll use it till they will not let me , but I regret not waiting 24 hours on any updates. I paid for this app along time ago already..Version: 11.4.2

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

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

Great CalculatorThe support is good because they are video tutorials that you can read on how to. The digital paper printer function is extremely helpful for you to review your work and saves time. Would definitely recommend to someone and have..Version: 10.9.3

Owner D.R. Woodworks Portsmouth, NH.This is not another feet and inch calculator, it’s obvious the developers work in the building trades or sought the input of professional tradesmen. My only complaint is that another piece of technology has made a lot of our hard earned knowledge available to any idiot with five bucks and a smart phone!.Version: 10.9.3

Great app!Great app! Way better than purchasing the calculator. Ive broken my calculator on job sites and have had to buy new ones. Now every time I get a new phone the app pops up on it. No more purchasing new calculators for framing.Version: 11.3.6

Widget would make it Perfect!Comes in handy when needed on the job site. Would be perfect if a widget was available and you could swipe right to access the calculator. Pcalc has this functionality and makes it available when needed..Version: 11.4.2

GCI use this calculator everyday! It has always been a great app to use easy to operate and gets you results you need when you need it. I got it for all my guy’s and it’s has been a valuable tool on the job and off!.Version: 10.9.3

App version, yeaaaa.I purchased the hardware version of this device several years while working in construction, and was thrilled when it became available as an app for my iPhone. Thank you so much..Version: 11.3.6

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

Very convenientAfter using the stand alone pro Calc I find that having it stored on my phone is much more convenient. It is with me at all times and is very easy to use..Version: 11.4.8

Used a Construction Master since the eightiesMy first construction master was a Construction Master III, that my wife bought me for my birthday. That original purchase made me the star of the framing crew. I also owned a CM IV, and now the CM V, as well as the app. As a tradesman, I found it indispensable on the job..Version: 10.9.1

I want to buy it, not to be forced to commitment.I love this brand. I have a physical calculator of this brand and I’d like to have it conveniently in my phone, but I want to buy it, not to have an annual commitment. It doesn’t make any sense to me. I was happy to download it and I was very disappointed having to delete the app. ☹️.Version: 11.4.10
