GeoGebra Classic 6 for Android

Nothing works right anymore. The new UI is REALLY stupid, no traditional menu bar, instead you have this weird sort of touch-based interface that you click on.... it's really messy. But the bugs are what really kill me. Some I've noticed now: If you try to save a document, it will ask you to log in in order to save. You can click "log in later", but then it does nothing. I opened a ggb file on my computer, edited, kept going to "save", but nothing happened. If you Export an image to your local drive, and try to overwrite an existing file, you get your standard dialog. But if you click to "replace" the existing document, nothing happens. The dialog closes but the document does not actually get replaced.

I like this, you can do a lot with this graphing calculator app

Every single useful tool is hided unless you create an account and log in!

I've just started using GeoGebra for my classical geometry class and I've found it very intuitive and functional for geometric constructions. That being said, the seeming lack of an option to save files locally once logged into an account as well as the lack of a normal array of toolbar menus are mystifying design choices in an otherwise very functional application

I dont know why this program has decreased in quality, it used to be a wonderful tool for solving equations while also graphing them. If you ask it to solve an equation with multiple variables, geogebra assigns its own values to those variables and if you try to delete the values it assigned it deletes your entire original equation. This was not an issue when I first started using geogebra and I dont know whos smoothbrained idea it was to add but its terrible.
