Keeping speakers on time

Welcome to the Zoom Community, @mart1n.

Using a utility like OBS, vMix (Windows only), or Ecamm (MacOS only), put the timer into your camera video feed, do not Spotlight it, and set Attendee View to Speaker (or Side By Side Speaker when screen sharing).  This way, Panelists can see the timer (provided there can view the gallery), but the audience won’t see it. I’d say this works great for 80% of my speakers.

I do use an online tool called StageTimer.io for setting up the timers. It’s relatively inexpensive (there is a free version), and can be set so that timers automatically start one after the other – they stay on time. 

Hello Ray, Thank you so much for the suggestion. I've had a look at Ecamm, which looks like it would do the job, but something like buying a Ferrari when I need a Mini! If that is really the only option, maybe I'll explore the trial version and see if I can get it to work, otherwise practice holding a timer up to the camera!

Use a countdown timer app or software that can be shared on the screen alongside their presentation, or utilize a second monitor dedicated to displaying the timer.
