1. 4/5Great

   Works very well. I just have 1 thing to say. In the app, the section where the function history is shown seems far too large. And the buttons are too small. Perhaps you could implement some features in other calculators to fix this. For example, some calculators have you swipe down from the answer bar to view your function history. Also, there seems to be no way of using subscript like on the computer version. Although it is present in the graphing calculator app. Also, the median function is missus in this app where it is present in the graphing calculator app. And I would like to suggest a function for the mode of a set of data.

2. 4/5Very good, but could have some improvements

   This app is very good so far. However, here are my suggestions. “Expression open, “needs to be announced by voiceover whenever clicking into an active expression. Braille mode should not have to be toggled on and off in settings when using a braille display. of course, I am using an iPhone 8 plus. I have not downloaded the graphing calculator app yet, but I will do so when I can. I see this being helpful for my future students, and a replacement (if not an add-on) to the Orion TI 38 talking graphing calculator, and the Orion TI 34 talking scientific calculator.

3. 5/5Clean, fast and Stress free Math Calculator

   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.

4. 4/5Layout funky, ads horrible...

   For anyone who has the muscle memory from using 10-key, this will infuriate you...and let’s not forget the slide-up ad that just always seems to know when you’re going for the ‘equals’ key, and pops right on up in front of it. I could go on and on about the ads, but that is the theme of these reviews, so not necessary. There are multiple other apps I would recommend before this one, but for educational purposes, Desmos is the most thorough and accredited...and exponentially better than this one.

5. 4/5My fourth evaluation finally wins!

   I was looking for a calculator that would let me do some basic algebra, then take the arccos of the result and show the value in degrees. I thought it was a pretty simple ask but three other calculators failed me. Finally I found this one and my problem is solved. I’m docking one star because the UI got a little confused when I wanted to wrap a whole fraction In parentheses. It assumed I wanted to put them around the numerator or denominator. I fiddled around and eventually got it to work. In all it looks like a solid app.
