Construction Master Pro

I have used some version of this calculator for I believe the better part of thee decades now. I love the convenience of it being on my phone which is with 24/7. The only draw back is the screen shutting of and having to reopen my phone every time I want to enter something that it took a little bit of time to verify or measure. This could be changed in settings I am aware but as most of us, I don’t want my phone laying open indefinitely. For large projects I still use the stand alone calculator of the Construction Master Pro. The convenience of it always being with you without having to carry an extra device and how easy it is to load updates, makes it a must have for all serious carpenters or tradesmen. Well done! Ron

I’ve been using this calculator for well over 20 years now. As a young man starting out in the trades, it was a big investment to buy $70 to have on the site, but I did it. As soon as the app became available, download it in 2005 or 2006 I have had no issues with the app or the calculators that I own they work extremely well, however, and that is a big however, when I recommended this app to my new hires, they told me it cost $20 a month. Since it’s clear people involved with calculators know how math works equivalent cost of this app over the next 16 years would be $3840!!! There is no way in good conscience that I can recommend this to any young man starting out in the trades. Any calculator can do this math for you. It just not worth it.

Hello, no, definitely that is not our pricing. Yes the app has switched to a recurring payment, that is due to the ever changing valuable features we create and support. The app comes with a no-risk free 7 day trial to try before buying, pricing is shown in App Store as well as at start of trial, again what you mentioned is not correct regarding pricing. Thank you for the feedback.

I had purchased the stand alone calculator many years ago and the app at least 4 year’s ago. The calculator holder on my tool belt is a perfect fit for my phone. This is a great app as well as the stand alone. Best of all the help and manual is one click away if happen to forget the keystrokes for the stair layout or any other function. The app is similar in cost to the stand alone, but I would still own both. When I do not have phone in my tool belt the calculator is there. The new calculators have a tough plastic shell and the older version have an opening cover like a notebook. So I guess I own three. This is a great calculator layout for a builder.

I 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.
