lectureStudio is a free software tool for presenting PDF-based lectures. It integrates a wide spectrum of interactive features (e.g., annotation of slides by many pen-based tools), streaming and recording of audio and video, classroom response (interactive quizzes and messaging system) by smartphone web-browser, and much more.

lectureStudio does not require external servers and can also stream lectures by low-bandwidth connections (e.g. GSM mobile links), if necessary.

A presentation of the tool can be found in the demo section.
