Simple & easy to use  LucindaArnold  5 star

Unlike the Jobber6 (which is better for more detailed info needed)



I have used hand held model since the 1980s. I have repurchased 3 times. The new help screens are a big bonus. I promise that you will not be sorry. Keep up the great work. Gobobo IN.

Love your product. Used your calculators for years. Great app just like the real thing. App is worth the money. Once you use the app and understand how to apply it basic carpentry roof calculations stairs areas concrete rake walls all become second nature.


Please add delete/backspace button  BlaineT88  3 star

I have the original construction master calculator and it has a delete/backspace button but this app doesn't, so if you make a mistake you have to start completely over. Please add one...... Thanks. Other than that app works great. I use it on a daily basis.

This is just like the real deal! Great app

Not a rookie

Very useful!  Not a rookie  5 star

This is a must have if you are in any type of construction. I bought a CM5 calculator several years ago and now I have the app on my phone. Takes a little while to learn how to use but be ry useful in almost every type of construction. Worth the money!


Wonderful  LilG33ZER  5 star

Just like the calculator I grew up on, but now it's with me all the time!


Be careful, amounts wrong.  shane20715  3 star

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.

What I was looking for in 2009...  Architectural Designer  5 star

Finally, it's on my iPad... On the next update, it needs rotate in Landscape view because not everybody uses their iPad in Portrait, I bought a case that is designed to hold my iPad in Landscape. I don't feel like taking the case off everyday at work to use this app, that will become a total drag. There should be another version strictly for the iPad to take advantage of the bigger screen, because pressing 2x takes away the sharpness and clearity, appears out of focus. If you could please correct this soon, don't make us purchase this twice ! you guys are charging too much for this app, this app should have been priced around $7.99 because the "off" and "On/C" keys are missing ! If those two keys were there, then it's worth at least $9.99, it's over priced, really !!! Thanks...


iPhone App done RIGHT  Banyanquest  5 star

I have been using Calculated Industries products for many years and find this app to be great addition. I can see myself with few apps as they bring more industry specific calculators on board.
