Why are there so many different apps?

In order to satisfy our user community while simultaneously being compliant with regulations for high-stakes testing, we have different GeoGebra Apps from which you can choose. This allows students to use the power of our apps for high-stakes tests and paper exams while restricting their access to the internet or other software that are not allowed during these tests. At any time, you can also use the Calculator Suite or Classic app to access the fullest power of GeoGebra.

Have a look at the Comparison of GeoGebra Math Apps to find the right app that meets the testing requirements of your school district, state, or ministry of education.

How can I send a message to an author?

Go to the details page of the resource. There you will find the option "Contact author of resource".

Why are the CAS commands not working in Graphing Calculator?

We have removed all CAS commands and geometric construction features from our Graphing Calculator, as many states and countries do not allow students to access these features on high-stakes exams. You can still use numeric versions of these commands. Symbolic computations like the integral are now gathered in our CAS Calculator app which is available for Android on the Google Play Store and for iOS on the App Store. You can also use our Calculator Suite app for symbolic computations. The Calculator Suite is also available for Android on Google Play Store and for iOS on the App Store.

Which commands can I use in the CAS Calculator?

You can find a list of all CAS specific commands in the GeoGebra Manual.

Why are some numbers not exact in Graphing Calculator?

The Graphing Calculator outputs decimal approximations. Our CAS Calculator provides exact values.

How do I know if my Android phone supports AR?

You can check here if your Android phone or tablet supports AR: https://developers.google.com/ar/discover/supported-devices

For Android devices, you will also need to install Google Play Services for AR: https://play.google.com/store/apps/details?id=com.google.ar.core&hl=en

Why are undefined points not shown when plotting a graph?

Invalid values are not excluded, because GeoGebra uses the extended real number line. So this is the expected behavior.

Why is the input cursor displayed as a "j" instead of a "|"?

This is a phone-specific issue with Huawei phones. Please try to set the theme or font of your phone to standard setting and give GeoGebra another try.

How can I disable automatic updates for my apps?

On mobile devices you can disable automatic updates in the App Store/Play Store. To avoid automatic updates for installed desktop apps, please use a portable version. You can find an overview of the different versions in the GeoGebra Manual

Note: We recommend enabling automatic updates as they give you access to new features and bug fixes.

Can I save and load files on my phone?

Yes, you can save files offline on your phone by using "Save" in the menu. When asked to Sign in, scroll to the bottom and select “Continue without signing in now”. Your files will be collected in a GeoGebra folder on your internal memory. Tapping on any .ggb files in other apps, e.g. your file manager or an email app, will open this file in the right GeoGebra app. If you are using our iOS apps, you can use "Share" in the menu and then save it to your files on your device.

My computer crashed, is my work saved?

Have a look in the computer's temporary folder and look for the most recent file like GeogebraUndoInfo6533063557894725659.ggb or just type "%temp%" in Windows Explorer and press "Enter".

I can't open my .ggb file, is there a way to fix it?

Often a broken file can be fixed following these steps:

  1. Install a free trial version of WinRAR on your computer
  2. Open WinRAR and find your broken file
  3. Select your broken file and click "Repair" in the toolbar
  4. Select a location to save the new file and "treat as ZIP"
  5. The new file created by WinRAR should work now

If the file is still broken, you can send it to us via support@geogebra.org, maybe we can help. To find out more about GeoGebra's file format, read about it in the GeoGebra Manual.
