Don't buy this
I am a pipe fitter and assumed this would be the same as the known project calc that you buy at stores. It's not! Can't multiply add or subtract feet and inches and is basically just the regular calculator that comes standard on any phone. This is a scam due to the name that it goes by and the fact that they do not show a picture of it anywhere before you purchase it. If you are needing one for construction needs then this is definently not it.

Waste of money
Don't waste your time it's an over priced calculator! Weak!
Stay Away
There's a reason why you don't get to see any screen shot that depicts anything about this apps.... because it's absoulte rubbish and very difficult to navigate; not user friendly at all. Do yourself a favour, go to Lowes or Bunnings and buy a proper calculator.
Very poor App
I've just purchased the app and took the gamble that a bug posted in 2011 would be fixed by 13 April 2014, not the case. Very disappointed in Apple still allowing the app to be advertised in the App Store.
Bad
Might work for someone who works with the smallest quantities.
