Graphing Calculator Features:
Graphing: Plot polar, Cartesian, and parametric graphs. There’s no limit to how many expressions you can graph at one time—and you don’t even need to enter expressions in y= form!
Sliders: Adjust values interactively to build intuition, or animate any parameter to visualize its effect on the graph.
Tables: Input and plot data, or create an input-output table for any function.
Statistics: Use regressions to find the lines (or other curves!) that best fit your data.
Zooming: Scale the axes independently or at the same time with the pinch of two fingers, or edit the window size manually to get the perfect view of your graph.
Points of Interest: Touch a curve to show its maximum and minimum values, intercepts, and points of intersection with other curves. Tap any of these points of interest to see their coordinates. Hold and drag along a curve to see the coordinates change under your finger as you trace.

Scientific Calculator Features:
Variables: Assign values to variables that you can use in other expressions. Since all of your work is held in the expressions list, you can compute a value once and use it in many places simultaneously. Take advantage of the “ans” key, which always stores the value of the previous expression.
Arithmetic: Beyond the four 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.

Four-Function Calculator Features:
Simple and Beautiful: Just the basics done right. Add, subtract, multiply, divide, and take square roots.
Multiple Expressions: Unlike many four-function calculators, all of your previous work remains visible on the screen. The special “ans” key always holds the value of the previous computation (and updates automatically!), so you never have to remember or copy a result.
We are currently offering version 7.39.0.0. This is our latest, most optimized version. It is suitable for many different devices. Free download directly apk from the Google Play Store or other versions we're hosting. Moreover, you can download without registration and no login required.

Hello! I noticed a bug that isn't present on the regular desmos app and the original browser based version. When entering the function: tan^-1(sin(x)) it seems give an incorrect readout. Thanks! I really appreciate the existence of this app!

Though I have to use it for online classes, the trig functions like cosine and sine graphs are not correct. They show as a line that is slightly up going to 1 or slightly down going to 0 but not as the curve that what a cosine and sine function should be. Also why the keyboard for letters had to be in alphabetical order and not in the default type of keyboard that everyone knows and uses. Overall not a bad app to use

The grapher has many functions that the calculator does not have, which is really strange. So it would be very helpful if you could add these functions to the calculator as well.

this app needs the test mode like apple, come on! completely useless without start test option for students and not every student has an apple btw.

It's very helpful for checking answers but please don't use this to do your work because somethings might not line up with how you're learning things.

My phone blew up in the middle of class and made me fail all my finals. This app is very useless and makes ur phone explode. DO NOT RECOMMEND!

Very helpful, I can't deal with my graph calculator. Desmos save me this semester in my college algebra class.

Test mode was unavailable and was unable to access it after deleting and re-downloading the app.
