It is a nice app but there are other apps that does the same for free and it lacks some key features. For example you cannot fix a feature in the space which is very useful. Imagine you want to draw a quadrilateral with one angle 135 and the other one 150, you can give one angle but as soon as you give the other one the first one will mess up. For this reason you need a feature to fix that angle before moving forward

It cannot even calculate the circumference of a circle! Totally unintuitive interface! What a waste of money again from a selection of really bad geometry calculators! Sad. Doesn’t even deserve one star.

Really nice app for Geometry. Can simulate using a compass to create shapes and has a ton of choices to draw quadrilaterals and triangles and tons of other options I am barely delving into. This is the only app I know of that has these functionalities. I’m a math tutor for Geometry and it helps. I will be using this more now to create diagrams and images to use for Quizlet Flashcards.

Paid for this app and regret it. It was good before the developer gave up on it.

Wonderful app for both students and teachers. I connect my iPad to a projector to illustrate linear equations and geometry concepts to students in my math classes. This app is also helpful for solving problems without needing to constantly look for graph paper. Many great tools in addition to the graphing make this a good investment. Recommended.

Keeps crashing on iOS 9

Absolutely worthless as of right now. I have a whole class of iPads...luckily not on iOS 9 right now. Please update or return our money.

It is still unstable with I pad mini

I use it daily in my geometry classes. They continue to update it and continue to make it very useful!

Almost exactly what I was looking for. A tool for constructing geometry graphs when working on graphics or computational geometry problems.
