I love the Exam mode; however, I discovered a loophole. If a student uses text bubbles, those can stay open without causing an alert. Students can absolutely continue to text I've another during the exam.

I Love this app but I have always wondered why don't you guys add some options like something that automatically locates the isogonal conjugate of a point with respect to a triangle or quadrilateral, or something that locates the insimilicenter or exsimilicenter of two circles? Sometimes I face complicated diagrams that drawing them with these limited tools is so hard or even impossible. If you add these options this app would be impeccable.

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.
