Pympress is a free, open-source PDF presentation viewer designed for dual-screen presentations, lectures, and public speaking. It displays slides on a projector while providing a separate presenter view with notes, upcoming slides, and timing information. The application supports embedded videos, audio, and animated GIFs through multimedia integration. Presenters can draw annotations, activate a virtual laser pointer, and navigate slides without exposing transitions to the audience. Its timing tools track presentation duration and time spent on individual slides. Additional capabilities include automatic file reloading, customizable keyboard shortcuts, and configurable presenter layouts. Pympress runs on Windows, macOS, and Linux.
