GeoGebra Classic

Excellent application. I have the desktop version as well. This allows you to draw geometry as efficiently as using real paper but conduct very accurate analysis of resulting figures. There's nothing quite like it. The UI on the Android edition is exactly like the desktop version. You would think this might be an issue but it's actually a benefit as the UI is extremely efficient. If you take the time to figure out how to use this app you'll have an incredible tool at your disposal. Geometric principals are the bedrock of Calculus, students should do themselves a favour and grab this app!

I changed my mind. This is very powerful application and it is the right tool for the right tasks.

This app is very useful.

Best for student

Essential mathematics application and tools: indispensable and superb.

Its so helpful in each and every way

wait wait wait Why does it lugs so mich?¿ And why is this so weird¿?

Like to much

The app is slow because it uses cordova... It's a shame that such a powerful tool isn't available natively for Android. The dev fixed my problem with boot crashing, and now the app can be used on Android 7.1

Useless. Keyboard covers input bar.

Better every time I revisit

Bit slow

Thank you so much Geo! You helped me a lot! Best wishes from Iran

It's highly functional with many tools and has nice interface.

Don't download this application if you hate math, do you agree?!

fantastic.

used to be good, then the keyboard got changed and input became ridiculous. Having been told in responses to my criticism of the flaw that I was right, the keyboard had been bonkered, the devs have managed to not fix it despite saying they fixed it. sorry folks, this is no good if you want to input commands.

Best app for mathematics so far

Famous in chanels

Very useful. I'm a math's teacher and use it everyday!

Useful application, but not reliable when working with it as some of its sub-utilities becomes defunt

Goooood

Should make this compatible with phones. Works well on tablets

Love it

Good mobile rendition !And has also no ads, nor strange permission requests. This is cool! Now only 3D graphs would be fine, for the 5th star!

Useless. Crashes every minute or so.

Can't believe I didn't discover this sooner. An amazing program. But you need powerful hardware if you want to take full advantage of all its features.

Hi. Thanks for the update and new features. It has got really better but the app is still unstable and most times during working it jumps out of the program. And usually i will lose my project without having backup because of this problem. Tablet: Galaxy Note 10.1 (2014 Edition) LTE Model (Snapdragon). Thanks for replication :)

This app, and Geogebra in general, is the only way in which I am able to see/show mathematical concepts such as the differences between incenter, circumcenter, orthocenter, and centroid. It makes it crystal clear why there are so many different centers of a triangle and why and when the orthocenter and circumcenter are outside triangles. Triangles can be manipulated dynamically and the effects seen instantly. The same holds true for conic sections. My favorite thing about this app is that I don't feel I have to reinvent the wheel to learn. Mostly everything I want to see/show has a well-crafted Geogebra file that can be downloaded and manipulated for free by searching the Geogebra materials. The .ggb files are consistent across Windows and Android platforms and I have spent years using GeoGebra since before they even had an app. In a word, . . "Brilliant" !

Nonsensical, stupid and a waste of time. Don't waste time in installing it. Tomorrow is my exam and this **** app is not working after installing 3 times.

Incredibilmente utile e perfetto, anche per far scoprire la geometria analitica!

...and open source!

It crash ever

هندسه دوست دارید حتما نصب کنید

Loved it...

This coming monday, we're going to use it for our math class. Wish us luck!

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 :)
