PhySyCalc reinvents the calculator. More intuitive than conventional calculator apps, for example, you drive 250 miles on a full 12 gallon tank of gas and want to calculate your mileage. In PhySyCalc you can skip all the unit conversions and just enter 250 mi/12 gal. PhySyCalc gives you the answer in mi/gal. Or, if you like, km/L or L/100 km, all in a few touches of your finger. Do you cook? Shop at market? Then PhySyCalc is for you. Scale or convert your ingredient quantities in no time at all.
Are you a science student or professional? Then PhySyCalc is really designed for you. PhySyCalc has all the math functions you expect on a conventional calculator and more. Using just the element symbol, you can retrieve atomic weights, isotope weights, and isotope abundances. Built into the calculator are many useful mathematical functions, as well as a number of useful physical constants. Included also are the speed of light, and the mass of the electron, proton, and neutron, all with appropriate units. Never again do you have to worry about whether you used the right units for a physical constant.
Wow! Where do I start? This app is a complete game changer as a scientific calculator. I've never seen a calculator app that lets you add, subtract, multiply, divide all your numbers with units and then lets you select the answer in whatever unit you desired. It's a paradigm shift. Normally I do the calculation twice, first in a calculator using only the raw numbers without any units, and then on paper, checking that the units all cancel and you get the correct answer in the correct unit. With this app I can do it all in one step. And getting the answer in the desired unit is a simple matter of scrolling through the list of possible answers to find the one in your desired unit. Where was this app when I was doing all my chemistry homework problems? Another cool feature is that it has buttons for all the important physical constants with units, so no need to look those up. You can even recall atomic weights using only the element symbol.
Wish that it had the ability to define variables for use in later calculations.
