Most run of show tools end at a PDF. You're up! is one live link: change a time and every device using it updates. No login, no app. Anyone with the link can adopt it and add their own private items on top (load-in, mic check, speech notes), anchored to the shared rows so they move when the schedule slips. Their layer stays on their device, so one link works for the AV team, the caterer and the MC. Free to use forevever. Calendar, Who and Branding are in paid.
