Can't graph circles, other non functions You can only address x as a variable, so any equation with x and y as a binomial is off the table. Also, the visual design leaves something to be desired.

Bryan Huang

Excellent math graph app, but with some drawbacks. It's the best and simple app I've ever seen of this kind. No ads and easy to use. BUT could you add features like polar coordination system?

Darko Aqua

Great and simple Would like 0.1 for coarse and 0.01 for fine x axis steps instead of irregular intervals. Other then this excellent app. Thanks!

Fernando Chequetto

Really good app If you need to do graphics, just put it in. It will precisely show you what you need. It has a very clean and beautiful design and it's very easy to use. The only thing that saddens me it's the fact it can't do even more. Some graphics it just can't do. But yes, definitely recommend!

Tom André Steinsgard

Great! Very usefull It's a great tool, however, I feel that the lines are very hard to see, if you could just thicken the lines I would without a doubt give it 5/5

## Graphing Calculator by Mathlab

If you're looking for a graphing calculator app that works smoothly and seamlessly, you've found it! Graphing Calculator by Mathlab is a scientific graphing calculator integrated with algebra and is an indispensable mathematical tool for students in elementary school to those in college or graduate school, or just anyone who needs more than what a basic calculator offers. It is designed to replace bulky and costly handheld graphing calculators and works on virtually any Android phone or tablet.

Furthermore, Graphing Calculator by Mathlab displays calculations as it performs them on the high-quality display of the Android device, making it easier for the user to understand the calculations and see them clearly. This app has two great strengths. First, it acts as a fine scientific calculator, but, more than that, it displays the intermediate steps of the calculations as you type. It allows the students to both watch and learn how the calculations are made and how to find the final answer. Second, the graphing ability is absolutely stunning! Not only does the calculator beautifully display the graphs, but it automatically generates the x- and y- values and displays them as well.

## FreeGeo Mathematics

Dynamic geometry system for Android which optimizes interactive Geometry, Algebra, Statistics and Analysis for the touchpad and contains hundreds of powerful features. Free Geo won the german price "Preis des Bundespräsidenten Jugend forscht 2013".

Create geometric constructions and move, scale or rotate them with one or more fingers.

With the Freehandmode you can additional build your lines, circles, squares, rectangles and many more by drawing them on the screen. The system will detect it and create the object for you! For example, you can draw a freehand circle through three given points to create their circum circle.

Furthermore, you can create even complicated mathematical projects by using one of 70 tools to add different points, circles, lines (Perpendicular bisectors, Orthogonal lines, Tangents, etc.), conics, angles, functions and many more.

Define functions and parameter curves to display, integrate or derive them. Create analytical objects like tangents and circles of curvatures or combine your creation with sliders, text and check boxes. Even exact calculations are possible with the own FreeGeo Computer-Algebra-System, for example solving equations.

FreeGeo can be used in other sciences, too. You can do statistical calculations by using one of the regression methods to interpolate given data points. And it is a nice app for learning for school!
