Desmos Scientific Calculator

About this app

Move beyond arithmetic with the Desmos scientific calculator! In addition to the basic operations, take advantage of a variety of built-in functions for exploring trigonometry, statistics, combinatorics, and more. Or, define and evaluate your own functions -- all for free.

At Desmos, we imagine a world of universal math literacy where math is accessible and enjoyable for all students. To that end, we’ve built a simple yet powerful scientific calculator that runs on the same blazingly fast math engine as our next-generation graphing calculator, but with a more streamlined set of features, for those times when you just don’t need a graph. It’s intuitive, beautiful, and completely free.

Features:

Arithmetic: In addition to the basic operations, the scientific calculator also supports exponentiation, radicals, absolute value, logarithms, rounding, and percentages.

Trigonometry: Evaluate the fundamental trigonometric functions and their inverses, using either radians or degrees for angle measure.

Statistics: Compute the mean and standard deviation (sample or population) of a list of data.

Combinatorics: Count combinations and permutations and calculate factorials.

Other features:
- Works offline, no internet connection required.
- Create and evaluate your own functions using familiar function notation.
- Assign values to variables for later use.
- View multiple expressions at once. Unlike many scientific calculators, all of your previous work remains visible on the screen.
- The “ans” key always holds the value of your last computation so that you never have to remember or copy a result. If you change an earlier expression, the “ans” value updates automatically.
- Did we mention it’s free?

Ratings and reviews

Been using Desmos for years and it's the only calculator I use. I have noticed a small issue on my OnePlus 8, though. Whenever I have a row selected/highlighted and I switch over to another app, the keyboard pops up when I switch back to Desmos. This isn't a big deal normally but manually hiding the keyboard every time I reopen Desmos gets pretty annoying when I'm going back and forth a lot. Please consider fixing this. Besides that, I love the app and I'm happy to call it my go-to calculator.

Overall, excellent. Good design, layout, and controls. I also like the option for the answers to be displayed in fraction form. However the keys are a bit too small (it can get tedious avoiding clicking on the wrong ones when working with intricate equations), and the dark mode unfortunately isn't perminant (I need to re-enable it every time I open the app which is frustrating). Please fix those two things and I'll give you five stars.

Really solid calculator! It's super helpful to be able to define variables and build my own functions. I work in a laboratory, and this comes in hand for running repeat calculations. The only improvement that would make my experience way better would be that ability to save certian functions (like on the graphing calculator) so I can just load them up as opposed to re-writing them all each time I need to use them. Other than that, I'm real happy with this calculator!
