Calculator SC-323PU

I submitted a review 3 years ago and at that time I mentioned I had been using this App for two years. So now I have a total of five years expirence . So I have been so happy with this application and author. I still use the app each day and It works perfectly. Remember it has full instructions that pop up whenever you turn the iPhone to landscape view. This is a super super calculator application. I recommend it to anyone studying math, working as an engineer or chemist, working in finance, working or studying computers. Or just about anybody that can use a full featured calculator. Try it and you’ll like it.

Everyone else’s written reviews have captured why this calculator is the best. For the Developer: Please Please add the ability to change the ordering of the list of fundamental constants. I only need those that are relevant to physical chemistry to appear at the top.

I was looking for a simple fractional calculator app and came across this one and love it. The interface is very similar to TI or Casio scientific calculators so it's very easy to figure out how to use it. I was lamenting that it didn't have a bin/hex calculator but one day I accidentally swiped right and discovered the other calculators. I'm really impressed with the quality of this app, especially since it's free.
