Very useful and I use it constantly! ### 5/5 — Excellent calc *2025-09-17, version 12.5.50* Excellent calc for a contractor user friendly ### 5/5 — Excellent app *2025-04-04, version 12.5.50* I use this app all the time for work. The many functions are impressive and easy to use. ### 5/5 — Concrete Calculator *2024-09-08, version 12.5.50* It’s a life saver! My only complaint is I have it on my iPhone and my Samsung replaced my Samsung with a new one and it won’t let me use it for the new phone without paying for it again. Disappointing but not the end of the world. ### 5/5 — XD *2020-08-04, version 10.4.0* Cccff ### 1/5 — No good *2017-11-08, version 1.3.1* No sirve necesitan arreglarlo se frisa . ### 4/5 — Concrete master *2014-08-23, version 1.2.0* Great for figuring just about anything concrete related. Did everything long hand for a longtime. This saves me time and money and is much more accurate. Great to have on the phone so I don't have to carry my real calculator around. Thanks, I would recommend this. ### 5/5 — Owner NH Construction *2012-10-07, version 1.1.2* I was so happy to find this app for my iPhone. I have been using this concrete calculator (the actual calculator) for over 15 years. I have never had any problems with any kind of calculation problems. Best concrete calculator I've ever known of/best app for my business!! ### 3/5 — Be careful, wrong amounts. *2011-03-04, version 1.1.1* If you are a professional be careful, it will not give you the proper amount of concrete bags. I don't think that this thing realizes that there is .0222 yards in 1 80 lb. bag. Example: 5x5 at 4" deep is 13.9 bags, this calculator insists that it is 12.5 bags. I am glad I am not using this in the field. I would be really screwed and you don't want to be short. All of the Construction Master series has the same problem. I have them all and they are all wrong. ### 5/5 — Landscape designer-owner sscsportcourt *2011-02-26, version 1.1.1* Great app! Best part, one less object to carry ## Frequently asked questions about Concrete Calc Pro Calculator ### What does Concrete Calc Pro do?
