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.)
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.
Developer Response ,
Thank you for your review. For tutorials on how to use the application, please visit https://wiki.geogebra.org/en/Tutorials and https://www.geogebra.org/book/title/id/IkTRvSGU. We will look into the issue of fixed labels. If you can reproduce any closing of the application, please contact us at email@example.com.
I really like this app! I work with wood and don't have a protractor handy with me. I found all the angles I needed for the design I am making!! Super easy, and fun to use😁
