The latest upgrade changed the functionality of the app - the old format was better
As a steel contractor I find this invaluable
Already own this same calculator as a stand alone tool. Bought this app so I’d always have its features with me. Works great!
I love this in the mobile app. Problem is that an internet connection is now needed to use the app - it’s a pain as a result. If I didn’t already own it, I wouldn’t purchase it.
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.
The 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.
The perfect tool
Great app always working
This used to have a digital paper. If it’s still there I can’t find it
