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.
The fact that I tried it so it would help me on my test was fascinating. Then, I start the test and agree on the lock notification. The app continues to swipe up automatically and locks me out of my phone. I was in a bedazzlement for 10 minutes and worried my phone wouldn’t turn on ever. This app ruined my perspective on Desmos and Desmos’s reputation is forever broken in my mind and the mind of many in my school.
Legitimately good app, one critical flaw
AppsBrokenPlzFix
my algebra teacher loves this app, she encourages us to use it when we can, and she lets us use test mode during tests, the problem is, when in test mode, you can’t switch the mode on the calculator, so if i was in a graphing calculator and wanted to go to four function calculator, i couldn’t. i used this app on a test and when my teacher asked to see my minutes it wasn’t true, and it’s not like you can screenshot it either. this has tanked my grade since she thought i cheated on a big test. please fix!!!
Useful app. Legit.

This works just as well as how it does in either a Personal iPad or a School Managed iPad.Useful functions, and has the Assessment Selection for using it in tests at school.One suggestion would be to add horizontal mode, but other than that, this app is great!
Why no QWERTY?

This may sound ridiculous, but why isn’t the keyboard in the app a QWERTY keyboard? Instead of relying on muscle memory I have to actively search for letters which takes away precious minutes during an exam. Simple fix? Or at least the option to change it to QWERTY for those who like the current keyboard.
