Been using Construction Master Pro Calc for a couple months now. It’s basically a construction calculator app that helps with layouts, plans, bids, and estimates. Pretty solid if you’re into that kinda stuff.
Here’s what you can do: you can work in and convert between all the common building dimensions. And there’s also a trig mode that’s pretty handy. And the user guide is actually pretty helpful – took me a while to figure out some of the features but it’s all there.
Look, if you’re a contractor or work in construction, you’ll probably get a lot of use out of this. It’s not perfect – the ads can be annoying if you don’t pay – but overall it does the job. Worth checking out.
