I find this app intriguing to say the least. The analytic of a chamber or transformative geometry is a must have when you install a geometry app like this! Also, you can recreate a 1:1 scale of tung tung sahur and live to see another day of Epstein being alive! So glad this helped me push through my high school years high 😀

Seems like a powerful package for visually constructing calculations, but it's got a learning curve: you can't just click somewhere, but have to really know what you're doing with that click. Sketchometry (web version) is much easier to get started with, but its drawing tools are put away in inconvenient, non-intuitive fragments, making you click a lot hence-and-forth.

Almost great. The actual app is great, once you get past the nearly impossible zoom controls. An example. Set line lengths will default to horizontal. Four digit inputs will have that line run a long way off screen on a phone. There is no zoom slider, at least not one I could find, nor a zoom -+ button. Pinch zooming will almost always result in one or two additional points being added instead of zooming. Fixing this would make it a 5 star app but, as is, it's unusable on a phone.
