Good little pocket calculator
As an engineering student this app always comes in handy whenever I don’t have my trusty Ti-84 on me, and it’s the closest equivalent I have found on the App Store so far. Once you get used to the layout it is a powerful app and I’m glad I have it.
Perfect Calculator
This is exactly the perfect calculator for iPhone. In terms of the calculator, it actually shows your the equation as you type it, shows your old equations, and you can pull down equations or values into your current equation. If you’re a mathematician or an engineer and need a real calculator, this is about as good as it gets. 2 wishes: - an option to solve system of equations (complex, but that’s still why I reach for my TI-nSpire CAS usually, before this) - optimize for iPhone X ... this app is still running at the iPhone 5 resolution... it’s worrying me that this app is dying off, and all we need is Apple to do what it does best and cut support for some sort of API that this thing uses or something like that.
It is pretty good.
Very easy to use
The best calculator for me
This app is so useful, lightweight and simple to use!
Never use my TI84 anymore
I’ve used the App Store since it first came out and this is the only app I’ve ever written a review for—it recognizes when “e” is euler’s number and when it’s a symbol for scientific notation, knows when “-“ means negative and when it denotes subtraction, the graphing is easy to use— all its features are brilliant, and before this, I had never found an app that can totally replace my TI-84. Cheers to the developer!
Good
This seems to be the only non-paid calculator on the app store with memory, individual deletion, and easy copying. Even if it couldn’t graph, it would still be by far the best calculator I’ve seen so far.
Good but doesn't show unions
This app is great for everything but showing more than 2 unions on a graph
Step aside, TI!
This app is the best! Points along the graph are easily identified, and derivatives are given, just touch and go. Graph scale can be zoomed in or out, no complicated string of keystrokes involved. The only reason I'm keeping my graphing calculator is because I can't use this app for a test. If you are a math student, Good Grapher is what you need!
Okay but there's no x input..?
Needed to input an x variable but there was no leg for x
