Construction calculator

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.

Great calculator

Have used my desktop model for 30 years and couldn’t live without it until this app. Although the giant desktop is great for crunching numbers at home I always use the app on the job site. A bit pricey but worth it if you want an in depth construction calculator and especially if you are already familiar with the format of the non virtual model. Have no regrets about buying.

Thank you for the review and 5-stars, and for trusting us over the years!

Don’t waste your time unless you want to pay for an over-priced subscription

I had used the standalone calculator before and really liked it. When I saw the app I thought I would try it. Unfortunately, it would not let me run the app without choosing a subscription plan. Sure I could cancel in 7 days and not get charged - if I don’t forget. However, the price was so outrageous that I just deleted the app. 50 bucks for an annual SUBSCRIPTION is ridiculous! The calculator is good, so I might pay $30 or $40 to BUY the app, but I’m certainly going to pay forever for a subscription when you can buy the standalone calculator that will last for years for $50 or $60. Sorry I wasted my time.
