By using Academic Presenter, you can harness the power of slide-based software as well as canvas-based software simultaneously. I strongly recommend this software to professors and students since it supports many crucial needs such as LaTex, Digitizer, Video, Audio, Graphs, and etc.It is offline, so you don't need to be worry about security of the host website such as Prezi. Also it is free which makes it a good alternative for those who are in budget.
