Nice, simple, lets you set variables and use them later. Uses a UI model of writing formulas, not mimicking calculators. Can switch between exact fraction or decimal output. So it's my favorite calculator so far, only downsides I found were: you can't depend on when it will keep or clear your previous calculations when you switch away from it; plus once or twice it bugged up and showed outputs in the wrong line as if they were the output of a different calculation.

Keeps getting better even after 15 years of use & if you are good with mathematics the learning curve is very short. Take your time & it may surprise you along with the other 6 apps available & I always have updated them, eh? Yet I still like to use pen & paper or a whiteboards with various colors or I do have a 4 X 6 chalkboard in the basement? It is very heavy though & don't worry about the privacy & use the that you need to agree to in order to use these apps??

I like it a lot! I think is simple, clean and intuitive. Though, there is something that I find very annoying. If I already selected to use degrees as default, later while using the trigonometric functions it is required to explicitly specify ° (degrees). And the output switches without any apparent reason between degrees and radians. I would prefer to have myself control of the use between DEG and RAD. Instead of a ° button, I would prefer a DEG <-> RAD button.
