## What is Desmos Scientific Calculator?

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?

## Key features

- Basic arithmetic operations
- Trigonometric functions
- Statistical calculations
- Combinatorics and factorials

### 5/5 — Remaining true for people in need

*2026-06-04*

No advertisements, no purchases, no popups, fraction functionality, everything that you would need from a functional calculator without the bloat of other apps
The only thing that’s truly lacking from this is a step by step process and explanations

### 4/5 — AMAZING! But 1 problem I want to address...

*2026-06-03, version 7.49.0*

This Calculator Is probably the best one I have but one problem is the [ans]block which is super annoying to use, instead use the "=" sign and to use it, type after it.

### 5/5 — High-Efficiency Tool for Academic and Professional Success

*2026-05-01*

The Desmos Scientific Calculator, is a sophisticated and reliable application that streamlines complex mathematical tasks. It offers an intuitive interface that effectively handles everything from basic arithmetic to advanced trigonometric functions without the distraction of advertisements. For those balancing professional commitments with education, it serves as a powerful, high-quality resource for maintaining accuracy in any fast-paced environment.

### 5/5 — Clean, fast and Stress free Math Calculator

*2026-04-27*

Desmos Scientific Calculator has been a game-changer for my stats and calculus classes. The interface is clean, intuitive, and way faster than my old handheld. I love how it handles fractions, trig functions, and even complex expressions without lag. Graphing isn’t available, but for quick homework checks and exams where graphing isn’t allowed, it’s perfect. The history view saves so much time when fixing mistakes. Best free scientific calculator I’ve used — no ads, no clutter. Makes math feel less stressful and way more accessible.

### 5/5 — This is an amazing calculator app.

*2026-04-26*

I love how amazing Desmos’s scientific calculator is. It is good for education and even for everyday math. I love how it can do many things many other calculators cannot do, like fractions, variables when given a value, and more. I even like Desmos’s scientific calculator more than its graphing calculator. This app could even be better if it solved with variables even when not given the variable a value (like 5(x+2)=5x+10), but still it is amazing.

### 3/5 — No Quartile Settings

*2025-12-11, version 7.38.0*

One thing that would definitely improve this app is being able to find Quartiles in a data list. I needed this for my college algebra homework but this calculator says it does support the quartile function.

### 5/5 — Amazing

*2025-11-26, version 7.38.0*

Thank u devs this is awesome

### 3/5 — Add persistent large font

*2025-11-24, version 7.38.0*

I always use the calculator in large fonts, please add a persistent option so i don’t have to do it every time I use the calculator.
Overall a great product!

### 4/5 — Great app. Few tweaks?

*2025-10-17, version 7.38.0*

Love this app. A few things that could make it 5 stars:

* The splash screen takes too long to disappear. I wish there was a setting to turn off the splash entirely.
* I’d prefer (an option?) to only clear the history manually rather than automatically
* I wish it would save the large-text setting between sessions
* It would be great if I could navigate an expression by holding down space like I can in other apps.

### 4/5 — Memory feature request

*2025-09-12*

Two things would make this app great: 

1) memory of past calculations after closing the app and reopening it, and 

2) being able to copy the results of a previous calculation down to edit them. Instead, I need to write the equation in full every time I want to build on it.
