GeoGebra Graphing Calculator for iPhone

We’re pleased to announce the first public preview release of our GeoGebra Graphing Calculator for iPhones!

For the first release it has the Graphics and Algebra Views but we will be adding lots more features over the coming months. We have prepared the foundations well so everything necessary is already working under-the-hood (for example the LaTeX formula engine, and you can create – but not yet display – 3D objects).

We will be making new releases each month so that it will soon catch up with the Android version.

There are also some extra-cool goodies to enjoy:

  • brand-new native equation editor
  • freehand drawings and shape recognition
  • everything is running natively so it is super-slick to use
  • find out more in our tutorial Graphing Calculator Tutorial

You can download it now in the App Store – please let us know which features we should add next in the GeoGebra Forums or send us an email:

GeoGebra Exam Apps for Android Tablets and Chromebooks

The GeoGebra Exam Apps allow you and your students to use the power of GeoGebra during exams alongside paper and pencil (ie like a graphing calculator) while restricting their access to the Internet and other software that should not be used during the exam, see

We are currently working with exam boards in several countries developing special versions of our GeoGebra Exam Apps adapted to various needs. For example, the recently added NDerivative command and the Extremum / Roots Tools were added as part of this work. Today, we are releasing several new variants of our GeoGebra Exam Apps.

Note: While the GeoGebra Exam Apps for laptops can be customized by the user, the GeoGebra Exam Apps for Tablets each provide a different preselected set of features.

GeoGebra Exam Apps for Android Tablets

We are committed to making our exam apps available on all platforms, so iPad versions will follow in the coming months. For high-stakes exams, you can also combine the following Android exam apps with additional device-lockdown methods. For low-stakes exams, our exam apps provide a simple way to use students’ own tablets in exams without the need for any special device setup. Please see our GeoGebra Exam Tutorial on how they work.

GeoGebra Exam Simple Calculator

This is “just” a simple calculator, providing a basic version of GeoGebra’s Algebra View, while all other Views are deactivated. There are no GeoGebra tools available and access to commands is restricted to the level of a pocket calculator. However, the GeoGebra Exam Simple Calculator uses the same interface and keyboard that your students are used to using with our other GeoGebra Math Apps.

Play Store link:

GeoGebra Exam Graphing Calculator

The GeoGebra Exam Graphing Calculator combines the Algebra View and 2D Graphics View, while the CAS and 3D Graphics View are deactivated. Additionally, all commands specific to CAS are deactivated as well.

Play Store link:

GeoGebra Exam CAS

The GeoGebra Exam CAS provides access to all GeoGebra Views except the 3D Graphics View. There is no restriction concerning the use of commands or tools.

Play Store link:

GeoGebra Exam Apps for Laptops

GeoGebra Exam for Chromebooks

The GeoGebra Exam App can be customized by the users, allowing them to decide whether they want the CAS and/or 3D Views to be available during the exam.

Chrome Store link:

GeoGebra Exam Web App

The GeoGebra Exam Web App can be customized by the users, allowing them to decide whether they want the CAS and/or 3D Views to be available during the exam. The app runs in all modern browsers (eg Chrome, Firefox, Internet Explorer 11, Safari) simply by opening

Algebra Reboot!

This week we have released 4 major new features in the Algebra View of our online Graphing Calculator:

Input and Output Rows

Similar to what we have done in the CAS View since 2011, the Algebra View now shows Input and Output rows for most objects types so that you can see the calculation and the result:


Exact Fractions

To go with the the Input and Output rows, we have added the ability to do exact fraction calculations (like you are used to on regular hand-held calculators)


If you want the approximate answer, then you can press the arrow button to toggle between approximate and exact.


Automatic Preview

Another major enhancement is that when you are typing an expression in the Algebra View, you now get a preview in the Graphics View, and you also get a warning triangle when the input is not (yet) correct

Input Help

If you click on the “?” icon then you get quick access to the help for all the commands:


As always you can try out the latest and greatest release here: GeoGebra Graphing Calculator

As you may have noticed, we have been rebranding a little recently so GeoGebraTube has been renamed to GeoGebra Materials, and GeoGebra Math Apps now refers to our whole suite of Apps.
We are also working very hard currently on making GeoGebra Graphing Calculator for iPhone so we will share some more news about that soon (it will look very similar to the Android version which is now at well over 500,000 installs).

GeoGebra Exam

The GeoGebra Exam App …
