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,

I use this app for work (structural engineer). Used the free version for the last year, just upgraded to paid because I wanted to support the developer for a good, simple app that saves me time. Sure, I can do this math by hand, but this is faster and reduces errors. The paid upgrade literally cost less than I charge for three minutes of work. The free version definitely saved me more than that last year. Gives me more time to do the actual hard part I get paid for! Thanks!

I'm often dealing with one measurement being fractional, and one being decimal. I have always just converted them both to decimal and used a standard calculator, but this can be a pain. I've considered buying a regular construction calculator, but I figured I'd immediately lose it. My phone is always on me so this fits the bill nicely. It has some more advanced features which I'll look into eventually, but so far it's perfect. Paid the $6 to go ad free if only to support the developer.
