I this app is a game changer. I've been trying to get everybody to get it. People wave it off until I show them all the built-in features. To whoever creates this, thank you!!! New edit: I had to create a P.O. for deck railing for a sub and, after struggling to get the numbers and spacing right, I thought, 'This would be a great feature request for the world's best construction calculator.' Immediately after, I hopped on the app and found it already had it—ridiculously easy to use.

App worked great for a couple of years, but when I opened it today, it's just a black screen, and if you touch the screen it vibrates like a button was just pressed. I cleared the cache and same problem, cleared the data - same, checked for a virus - nothing, so then I uninstalled the app and reinstalled it - Still a black screen. Please fix the issue so I can have my favorite calculator app back.

Great.. At first glance it does no look like your average calculator, there for it does not operate like one. A bit confusing at first, then i dicovered just how simple and quick it is. For real, it is simpler and faster then the old way. And you will make a lot less entry errors. Im a steel fabricator dealing with lots of numbers and i wish i had this when i did carpentry work, didnt have smart phoned back then. Also this app isn't forgotten like so many other, the developer is always updating,
