Features & Capabilities

Good Grapher is a powerful scientific graphing calculator designed for students and professionals from elementary school to university. It combines a full scientific calculator with features like a history tape, real and complex numbers, multiple angle modes, and a broad library of constants and functions. It supports variables, a variety of operators, and convenient copy/email calculations.

2D and 3D graphing offer interactive visualization, tracing, auto min/max, zeros and intersections, with support for Cartesian, polar, and other graph types. You can draw multiple functions, customize colors, view value tables, and export or share screenshots. The built-in math solver handles linear and polynomial equations and systems. Some advanced features (such as inequalities and certain Pro options) are available in the Pro version. More details, screenshots, and news are available at goodgrapher.com and its Mac App Store listing.

User Reviews

Good Grapher is a powerful, TI-84–like calculator with strong graphing, easy input, and helpful history features, praised for being free and ad-free. Repeated themes note easy use, TI-84 replacement, and robust graphing, while common drawbacks include missing x variable support, occasional graphing limitations, and requests for system-of-equations solving and better compatibility with newer iPhone models. Overall, it's a versatile, highly-regarded calculator app, especially for students.

Pros

TI-84-like functionality and a strong calculator replacement
Intuitive, easy-to-use interface
Powerful graphing with derivatives, points, zoom, and history-based equation reuse
Smart input parsing and equation management (shows typed equations, recognizes e and scientific notation)
Free and ad-free use

Cons

Missing input for x variable
Graphing can be inconsistent or limited (some users report no graph)
Lacks system of equations solver (feature request)
Occasional accuracy issues in trig results
UI updates not optimized for newer iPhones (aging UI)

Recent reviews

Great for single calculations and “chain” calculations.

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.

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.
