Loved by millions of users, Android's highest rated scientific calculator.


Rove to navigate. Forget buttons
Natural Scientific Calculator utilizes Rove to allow to you edit wherever you need to. Unlike other 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 and we've finally brought it over to Android!

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.

Tackle problems together
Two minds are better than one. Send your equations to friends, classmates or co-workers to refine your approach to a difficult question.

Elegant and purposeful Material Design
A calculator app doesn't have to be bland and boring. Let the subtle animations and vibrant colors guide you through the hardest of problems. If you've purchased the Productivity Pack, select from a variety of beautiful themes including our battery-saving "Starless Night" theme.

Fractions, exponents and surds
Confused when your equation looks like this? 50∗1/(0.05/12−0.08/12)[1−((1+0.08/12)/(1+0.05/12))^3]. We are too, so we've made structures like fractions display naturally as it does on paper.

Updates
For the last 8 months our team has worked day and night to implement new features and updates - we're not going to stop anytime soon. Support us by leaving us a rating, review or by purchasing the Productivity Pack.
