This app is exactly what I need in physics. HOWEVER, it is missing one important function. Yes, the app can be forced to convert a fraction into a floating point decimal. However it cannot do it the other way around. In otherwords if I type in 3.2 the calculator returns 3.2 and not 16/5. It would be great if the app had a button that could toggle between fractions and decimals.

Don't walk, run to get this app. I teach a math intensive short course to a lot of people who used to hate math. I recommend this app to my students. They love it and say how simple it makes the most complicated math. It shows you every step and is very intuitive. It holds your hand all the way through your calculation. Please consider a financial version one day. Thanks for a great app.

Perfect except I would like a version for a tablet that is scalable and always on top. Very nice app!

Not clear on how to customize with minimal base functionality.

I am a fan of RPN, and let me tell you this is by far the best Calc I have ever tried. Congratulations for a job well done.

A fantastic calculator which has stopped me from panicking at having to use the MS calculator when I have forgotten my calculator in work. Works really well and the history is fantastic. I love being able to see the calculation algebraically as well. A pleasure to use. Only issue was trying to find the button for X10 to the power of. Long press the . button and it is there. Otherwise, great stuff and thanks!

This calculator is without a doubt the best calculator I've ever used. It has a beautiful layout and is infinitely customizable. Unlike most calculators that lose your entries as you do calculations, this one reveals your entire equation. Editing in the pro version is wonderful and macros assist with repetitive calculations. The design is so elegant that I cannot sing enough praise for this masterpiece.

Used it for five seconds and I'm in love. The perfect number engine is a revelation. I have always dreamed of yet never seen this in a calculator. It makes so much more sense to work this way. Especially for mathematically illiterate people like me, this presents numbers and relationships in a form that actually make sense. Brilliant... Needs constants and financial functions etc and then it would be perfect.
