This is really great. I have used this tool for my woodworking. This is cheap for what you get. Well worth the price.

Overall love your calculators and have used them for ~30 years, thank you. I would like to know what happened to the S.F. button? Please bring it back. It is missing on most, if not all, of your calculators.

Works as expected, great to have when I don’t have my physical Construction Master 5.

Not able to download to iPhone was able to download to iPad. I purchased lifetime app 10 years ago now it’s a yearly app. Ripoff

Excellent layout and intuitive simple design

This is by far one of the best calculator apps out there for your pocket any time any place it’s there and very easy to navigate!!! I’ve had this same app for years can’t even tell you how long but I’ve tried others and none compare.

i have tried dozens of these construction app calculators and found this one to be the best.

Absolutely a timesaver with plenty of capabilities Very useful, awesome

Accurate,consistent data entry with fast results. A must for do it yourself and professionals alike!

Works just like my 30 plus year old stand alone from CI but no stuck buttons and I can always have it with me.
