I don't see what this is for, can't find any actual helpful functions. Some menus can't be accessed because they are placed under the phones basic menu buttons, so maybe that's the issue. Really awkward UI overall. Can't set or even see values (those options seem to do nothing) so how could I do anything?

one thing is missing. or has error in it. when rotating a point about another point clockwise or anticlockwise there is only the option of rotating in degree. not in ° ' ". hence converting DMS in Degree truncates the small value of seconds. I want that feature in this app. please as soon as possible. thanks. I am a civil engineering student by the way.

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.
