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. 

Fully featured scientific calculator functionality 

• Radians and Degrees support

Mr Edward ,

Good user interface but overpriced and minimal updates

As a scientific calculator it has a good user interface, in particular with the ability to edit earlier parts of equations using a finger controlled cursor. Unfortunately this doesn't work for all functions (eg: you can't add in a square root function at the beginning of an equation if you didn't put it there to start with)

The range of functions is quite limited in relation to other scientific calculators on the app store and the lack of a functional memory system to re-use previous results makes it quite limited outside of perhaps a high school situation. Old results cannot be pasted into a new equation in the way a calculator with a memory function normally allows.
It lacks conversions and constants.
There are rendering bugs (stretched / overwritten button text) when using in split screen or slideover on an iPad which have not been addressed.
It is really quite overpriced and has not had any updates for a year or more. Much better value from a number of other apps. Disappointing.
