If I understand correctly

So I think this is a great app in many ways. It is much easier to criticize then to create. That said I believe the user experience of this app needs a little push in the friendly direction. In many ways this app succeeds where other geometry apps fail. It has a more fluid feel than some other apps of its kind. I love the in app icons, which are clear and easy to read! Some suggestions. *When deleting points and lines, it tends to delete in groups. I assume this has to do with the math behind the surface of the program. From the users experience this very frustrating. *I would like to see, two finger tool rejection when panning and zooming. It’s impossible to create segments that are far apart or when two points are close together, without the ability to zoom and pan. *Deselect tool (arrow) should be part of the main screen and not at the bottom of the screen in the tool pallet. More front and center. *Other ways to create angles. A copy and move segment would be helpful. I am finding it difficult to create an angle in the right orientation sometimes (parallel and perpendicular tools works great but sometimes i want to adjust more freely). I like the angle tool but sometimes I don’t have a line to build off of and I need to create one blind and in the right orientation. *Building on that idea. creating an angle by its bisector might helpful. *Adjust a preexisting angle possibly by clicking on the angle on the screen. angles are hard to select on screen. *Move a line or constrained point. The move tool only works for unconstrained points as far as I know. *Help banner when selecting tools might show a quick help snippet. Possible clarifying the tool without opening the help section. *Building a tool set would allow you to choose your favorite tools without the need to shuffle through the very long wonderful list of choices. I like the idea of creating a narrow toolbar set on the side which would take up less space on the screen. *Finally, I believe files are not automatically saved to a destination in the cloud. I don’t believe the app has a stored folder there. I learned this when the file I was working on crashed and I lost the file. In conclusion. Is this app designed mainly for mathematicians or can it be used more broadly. Are artists like me considered too.
AMAZING

I’ve learned so much from this app helped me study for my unit tests, extremely helpful I recommend!!
Awesome sauce!

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?
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.
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.)
Crashes constantly

I’m just trying to draw about 20 lines on the graph paper and get some angles and measurements. It crashed on me like 4 times after 10 minutes and I keep losing the work. Kinda surprised, I’ve never had anything crash on an apple device before. iPad Pro.
