Adverts OK expression calculator but the interface is clunky and adverts make it worse. Calc Etc is much better and is free (no ads either)
Well designed calculator. Best to me comparing to others.
Expect to see graph support.
Good tool for students
Great tool. Like it
Good but can be improved Says it does complex numbers - but although exp(i) works, log(i) sin(i) etc do not. I have moved to using addi instead.
