Won't save files on Samsung Tab S It is ok, but for some reason I cannot save any of the files. I have an account and everything, but none of my graphs or anything is being saved. It only comes up: "file cannot be saved". Please, someone help :)

Michael Vincent

Great app, needs fine tuning. I'm only giving Geogebra for Android 4 stars because the app is still a little clunky. I'm probably expecting too much for a CAS to work smoothly on my TF101, but this is the sort of device Geogebra should be geared towards.

Costas Lolas

Perfect Indeed, the app was useless before the update. Now there is no lag or any issue. Thanks for the great app.

Timothy Cahill

Doesn't work on my nexus 7 I love geogebra on Linux, but on Android, I can't get past the start screen

marali gb

thanks for great app it will work with all desktop geogebra commands, animation and trace on fac

Rohit Raizada

Great App, As our Highschool teachers are concern. It is good only for our teachers to teach, casually it is Boring.

Dear Silje, thanks for the report. In case you log out and save the file, can you open it next time you open the app? Does File > Export work for you?
Please let us know via support@geogebra.org, thanks. International GeoGebra Institute January 9, 2015

Sorry to hear that, can you please let us know more details via support@geogebra.org? Bugs Common please fix bugs. When editing an object and keyboard comes up the text is always hidden under the keyboard, make it auto align and take the input tab into consideration. When scrolling in the algebra tab it constantly auto scrolls back up to the top when trying to select something (priority 1, can't even use the app because of this. And the command surdtext doesn't work among other things. Annoying when trying to show outputs from trigonometric functions. Also make it possible to edit stuff in the algebra tab (by double tap like on the pc version) instead of in a separate window so that focus stays on the graph. Using an nvidia shield on stock android.

International GeoGebra Institute February 23, 2015

What problem do you have with GeoGebra on that tablet? Please let us know via support@geogebra.org, thanks. So now we need Internet to use it? Among other reasons why I don't use apps like One Note or Evernote is that I don't feel like having to log onto an account just to access file. I mean what if there's no wifi available and we need to access previous work? So it makes no sense to me that I should have to create an account on Geogebra just to be able to use it. And for the record I have tried using the "continue without signing in now" button and nothing works. Was a nice program before it, guess I'll stick to the version on my laptop.

Hi, if you save your files while not logged in, they are stored on device and you can access them from device. When logged in, files are saved to the server and you need to login again to access them. Since next release all files will stay accessible offline even when logged in. In case of further question contact us at support@geogebra.org International GeoGebra Institute January 18, 2015

Hi, GeoGebra is designed to work without internet connection. Internet is only used when saving/opening files to geogebra.org, without connection your files are saved locally. What problem do you encounter when wifi is off? Please let us know via support@geogebra.org. International GeoGebra Institute February 23, 2015

Can you start the app? Can you log in and select a perspective? Can you do some basic constructions? When does it fail?
Plese let us know via support@geogebra.org Again Bad Hi. Thanks for the update and new features. The lag almost fixed but the app becomes unstable and most times during working it force closes and jump out of program. Tablet: Galaxy Note 10.1 (2014 Edition) LTE Model (Snapdragon). Thanks for replication :)

International GeoGebra Institute December 2, 2014

Please try the new version! Laggy and Unintuitive After trying the app on a Nexus 7 and a brand new Nexus 10, I have concluded that the insane amount of lag and crashes I experience is not the device's fault. If it would save my work, not crash, and allow me to do basic tasks faster than 5fps, this would still be unintuitive to use. All of this is really a shame, because the actual features are very useful, but with the horrible usability there is no chance I'd reccommend this.

International GeoGebra Institute December 2, 2014

Please try the new version! Well past unstable This app crashes regularly. As in every one or two minutes. It commonly restarts the app on it's own and has an unusual touch understanding where it has every touch not where you want it. And the windows 8 version, hell the iPad version works better.

International GeoGebra Institute December 2, 2014

Please try the new version! Doesn't work properly This would be great if it didn't keep crashing on my Galaxy Note tablet. Also has really annoying problems like I can't work out how to edit a function once it is entered so I have to start all over again. Also when I use the 'squared' button the cursor stays in front of the index so I can't type anything after it. I want to use this for teaching but right now it is useless. Please fix it!

International GeoGebra Institute December 2, 2014

Please try the new version! Its free... and Gegebra rocks I am an avid user on windows... tablet is where I want to be with this tool. Samsung Galaxy Note 10.1, stylus in hand, this tool prior to updates was missing what my work needed, but some of that is there now... if not most :) The community value is huge, if you struggle on your device, do get involved online on your computer, be part of the solution to yours and others concerns/issues. Thank you Geogebra, thank you users!

Good desktop application, but runs very laggy on mobile This is a very good app with lots of functionalities, but there are just too much lag, other similar applications have no lag at all. Will rate 5 if fixed. (I have a quad-core Nexus 7 so it is definitely not my device's fault)

International GeoGebra Institute December 2, 2014

Please try the new version! Too slow As others have pointed out, this is just too slow to be usable on mobile. Other math apps like Math Studio do more and run super smooth. The resource needs for this app need an overhaul to be of any use.

International GeoGebra Institute December 2, 2014

Please try the new version! Not working correctly on samsung Galaxy Mega GT-I9205 Cannot draw lines or anything related to lines are invisible is there an update/fix for this machine?.wiki says only designed for tablets with bigger screens at moment.

International GeoGebra Institute December 2, 2014

Please try the new version! Why This app has a very hard to use interface and is very laggy. It crashes more often than not. Although it has many abilities and cool shapes, I will go back to using mathlab's calculator from now on. Work on fixing the problems and I might reconsider
