  • Not worth the lease. Costs as much as CI 4065!

    What a rip. The app will cost as much as the hand held dedicated Calculated Industries 4065 calculator in just the first year of leasing it! Every year thereafter is like buying another calculator! CI is just being greedy on a money grab thinking people will just see the lease payment as a smaller amount aggregated over a year hoping the consumer overlooks that it’s into perpetuity. I’ll keep using the $55 CI-4065 which I own outright. I enjoy the added benefit of ensuring my $1400 phone isn’t damaged on a job site or worse, develop wings.
  • For carpenters, it’s a must have app

  • Subscription?

    By odi426
    Why is there a subscription fee for this? Use the the 7 day free trial if you’re in a pinch, cancel, and then go buy the calculator from Home Depot. Subscription plan isn’t worth it.

    Reliable and practical.
  • Excellent App

    By Ycam20012
    If you’re making a living in the trades, you need this app. Always with me because it’s on my phone, not a separate device that I could easily forget or leave somewhere by accident. I use this app nearly every day. I’m a residential builder/remodeler and this is a go to app for roof framing, layout, gable walls, stairs, concrete, blocks, and brick takeoffs just to name a few. I am always finding new ways to use this app. Highly recommended.
  • Great app. Horrible subscription!!

    By Mudsmear2
    I’ve had this app for 5+ years and have really liked it. I still do as I don’t have to pay the monthly fee. But it’s the new users I wish to speak for…. Been recommending it to new employees as they come on board but won’t be doing that anymore due to the exorbitant monthly fees. No I won’t recommend your physical calculators either. You’ve ruined it with the decision to charge so much.

  • Construction Calculator App

    By mean ian
    I have used the handheld and desktop versions of the Construction Calculator since it’s inception. Given phones are typically at hand it is awesome to have the same function and quality on the phone.

    Been a lifesaver, used throughout 30 plus years in construction. I like that you can set the tolerance to your liking, so many functions, I’ve only used a few. But I know they’re all at my disposal. One tool for me that’s irreplaceable.
