## What is Quick Graph?

It is a powerful, high-quality graphing calculator that takes full advantage of the multitouch display and the powerful graphing capabilities of the iPad and iPhone, both in 2D and 3D. 

"The app you need to survive the next semester."
-- Gizmodo

A simple yet intuitive interface makes it easy to enter and/or edit equations and visualize them in mathematical notation. 

It's capable of displaying explicit and implicit (opt) equations as well as inequalities (opt) in both 2D and 3D, in all standard coordinate systems: cartesian, polar, spherical, and cylindrical, all with fantastic speed and beautiful results, which can be copied, emailed or saved to the photo library.

It also includes an evaluation feature to evaluate equations at specific points and a library where you can store commonly used equations.

Up to 6 equations can be visualized simultaneously in both 2D and 3D modes; this limitation can be removed by purchasing the advanced feature set. 

Features:
 - Enhanced 2D - 3D plotting mode for great hi-res graphics. 
- Adaptive 2D algorithms.
- Hyperbolic and Inverse functions.
- Functions such as Min, Max, if.
- Configurable axis decimal / π
- Independent 2D zoom
- Support for cartesian, polar, cylindrical, and spherical coordinate systems.
- Interactive expression evaluation.
- Library for commonly used equations.
- Swipe to delete equations from the equation list.
- Save to photo library.
- Copy to clipboard.
- Turn graphs on/off
- Drag to rotate - move.

The advanced feature set gives you access to:
- External screen support
- 2D tracing.
- 2D and 3D implicit graphs.
- 2D and 3D inequalities.
- Roots and Intersections (2D)
- Value Table
- More features to come!

### 5/5 — Mi app favorita para graficar

*2026-04-24, version 3.0.1*

La aplicación es súper buena y ofrece muchas herramientas. La versión premium permite hacer muchas cosas interesantes que, para un estudiante de ingeniería o ciencias exactas, es demasiado importante.

### 5/5 — 다좋아요!!!! 근데…

*2026-01-14, version 3.0.1*

다 좋은데 절댓값이 있는 그래프도 그릴 수 있게 해주세요!!!

### 1/5 — iOS26でライセンス有料版利用不可

*2025-12-01, version 3.0.1*

iOS26へアップデート後
advanced features がunkownエラーとなってしまう。

### 5/5 — Beautiful Display, Easy Equations Entry

*2025-08-30, version 3.0.1*

Quick Graph has a beautiful display and quick and straightforward equations entry. The display axes are configurable for scale, and the entire display can be translated easily with your thumb, allowing you to observe the behavior of the function over different ranges of abscissa and ordinates. High quality.

### 5/5 — Wonderful

*2025-04-26, version 3.0.1*

This is such a beautiful app! Thanks

### 5/5 — 亨利

Ein sehr leistungsfähiges Tool!

### 5/5 — Long Tradition of Working Well

*2024-10-17, version 3.0.1*

I've had this app on my phone for an eternity, and it just continues to work when I need it.

No in-app purchases other than a one-time $1.99 purchase (I forgot at first I'd made this purchase, but it's honestly less than most stuff costs these days). No data collection. No one trying to advertise to you in the app. It just works. Not all heroes wear capes, but this app developer is a hero.

### 4/5 — Casi completa

*2024-10-01, version 3.0.1*

Tiene muchas posibilidades en la versión de pago, pero le falta la representación en paramétricas.

### 3/5 — It’s ok

*2024-08-19, version 3.0.1*

Good for those who don’t need as much features but Desmos has more capabilities and has better ways of viewing equations. Plus y there is no in app purchases in desmos

### 5/5 — 素晴らしい

*2024-06-29, version 3.0.1*

いやぁ、素晴らしいツールですね。
公園にてポケモンGOをしながら散策している際に、ふとグラフの外形が知りたくなった際に重宝しています。
