Very useful tool

I wish I had this in chemistry! Now in physics, this calculator is invaluable. It's not always easy to remember the rules but this calculator makes it so easy. With it I can be sure I am doing the problems with the correct significant digits as well as learn the reasons for why the answer is what it is.

Good idea, useful app

This is a good idea for a calculator app. I teach university chemistry and see how useful this might be for students learning about sig. figs. A few caveats, however. Sig. Figs. is an simplistic approach to propagation of errors. If you’re serious about sig. figs., then this calculator may give you wrong answers. That is because it does not — and I see no easy solution in a simple calculator app— include the covariance between numbers. Ignoring covariance will give you less significant figures than you actually have.

As a chemistry professor, what I would like is a calculator that understand units and dimensional analysis. That would be a great app!

0 love

I, as a number 0 enthusiast, have always felt that 0 never got it's due. Other calculator apps would not let me put importance on the 0. But this app. This app has renewed my faith in numerals. The 0 has once more become significant! It shall no longer be overlooked in calculations! Hail the mighty writer of this app because He... Is... My HERO.
