Loved by over 1 million users, Natural Scientific Calculator is the fastest way to do maths.

NSC allows to you edit wherever you need to. Unlike other scientific calculators which make you mash buttons to move a cursor, our app allows you to simply swipe on the keyboard to get to where you need. You can also pinch to zoom and get an overview of complex equations.

Write as you would on paper 
Other apps make you enter equations on a single line like something from the 1970s. Our Natural Input solves this problem by allowing you to enter equations as you'd write them on paper, using fractions, roots, exponents and more. It's called a "natural display" and is a common feature on scientific calculators like the Casio fx-82 or TI-30XB.

History and Favourites 
Instead of having to type out long equations over and over, simply favourite them and retrieve them with a single tap. Guaranteed to speed up your workflow enormously.
