In many online sessions, the host has one plan, the speaker has another sense of time, and the producer is trying to move the webinar into Q&A without interrupting the talk.
PresentationTimer keeps those roles clear. The host or producer opens the control page. The speaker or shared webinar screen opens a clean display link.
That display can be shown in a Zoom screen share, placed on a second laptop, kept on a confidence monitor, or watched by a remote producer.
The host can adjust timing live without exposing controls to attendees or forcing the speaker to manage the clock.
When the webinar has multiple parts, the room can hold a small agenda for welcome, presentation, demo, Q&A, and closing.
The result is a calmer online session: speakers see a clear countdown, producers know what is next, and overtime remains visible when the agenda runs long.
