Hi hackers. This is my first app. I made it to scratch an itch I had: Be able to make a calculation quickly and share the formula and the results (copy/pasting the link). In the next iteration I think I will add some share buttons. As I said, this is my first app. Please please please give me feedback! Good or bad, everything helps! Thank you
