Very good; UI could be smoother

Overall this app is very good. I haven't found anything as useful for geometric construction other than Geogebra Classic. However, the tool palette is clumsy, especially compared to the one in Geogebra Classic. It takes a lot of scrolling up and down to get to frequently-used tools, where the Classic UI makes them all readily available.

(The screenshot here in the app store shows the icons on the palette in usefully compact arrays. They aren't like that in the actual app, and I can't find any setting to create that arrangement.)

No way to save files… after all these years!

First off, Geogebra is an awesome system and the Geometry engine is a masterpiece. It’s smooth and useful for all sorts of purposes, such as understanding geometry proofs, definitions of conic sections, or just playing around. But! The iOS version is useless for anything other than quick and dirty sketches because *you still can’t reliably save your work even after all these years*. Sure, if you look online, after extensive searching you will find various people explaining workarounds for how you can supposedly save your work, but you will find just as many people complaining that it doesn’t work right. It didn’t work for me: I used the “share” menu, exported it to files, and ended up with a .ggb file… but then when I went through the ridiculous workaround to open it, the file was corrupted and didn’t even remotely contain what I started with. In the support forums I see years of people complaining about this inability to save files. It’s kind of ridiculous. I encourage the developers to either support iOS or not… but don’t make a frustratingly incomplete app.

Amazing App

I love the app as it really enables a lot of interaction and flexibility to design lessons and examples. The drawback is the learning curve to use the app. More refined demonstration is needed to clarify the tools. The app does randomly close as well but not so often that I would not recommend it.

One key feature I would like to see added to the app is the ability to move labels around so they are not clipping the image created.

Overall, once I learned to use the app, I enjoy using it for practice exercises with my students.
