In short

Slate Calc is a scientific calculator that displays math as it appears on paper, with stacked fractions, radicals and integrals with limits. It is aimed at students and anyone who needs exact results, since fractions and roots stay simplified and can be switched between formats. One notable point is that it works fully offline and has no ads, accounts or tracking.
