Description
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?

Comments on Desmos Scientific Calculator for Android
★★★★☆christopher Kokkinogoulis· Jun 13, 2026
Demos is great for a calculator. The only bad thing is that the keyboard is a bit small but everything else is PERFECT.
★★★★★Wojciech· Apr 7, 2024
A really good calculator app. Useful when I don't have a scientific calculator with me. The only feature misssing is dark mode that persists after closing the app.
★★★★★Aniya Green· Feb 17, 2025
My teacher suggested this app to me to help with math, and I love it so far. There's even pi you don't see that very much in other calculators. So I actually do love this so one day if I don't have my computer, and we need to get on the app I can just pull it up on my phone. And I love math, so I would never cheat and or do something else on my phone while in math class. I just love this app so much I recommend this to everybody still in school and college. 📝 Learning is fun so I do recommend. 📖
★★★★☆Jesper “PeeJay” Thorell· Apr 16, 2024
Functions in this calculator are awesome. Would love dark theme, possibility to rotate phone to landscape and lesser "voids" between buttons. Still it is by far the best free calculator I've used.
★☆☆☆☆J Cross· Oct 14, 2025
WHY ARE THE NUMBERS SO SMALL? WHY Can't I USE THE BUILT-IN KEYBOARD TO TYPE NUMBERS?
★☆☆☆☆Jeremy Holland· Jun 9, 2025
Either I'm doing something wrong, or this calculator is seriously deficient (or is crippleware). There are no buttons for log() or ln(), and if I type them in using the keyboard, the calculator reports that it doesn't support that function. It also refuses to evaluate the cube root of 27—literally the expression that makes up the app's icon—and it reports 'This calculator does not support the nth root function'. And yet it supports complex math LOL.
★☆☆☆☆Maimunur Rahman· Dec 8, 2025
Can't solve equations. What's the point of giving the option of using letters if we can't solve equations?
★★☆☆☆Susan Feigenbaum· Nov 30, 2024
Bummed by this, I was hoping it would be like having a demos tab open on a desktop. However, you can't copy or paste anything into the calculator, and if you close the app and come back to it all of your work is lost.
