As answered by people managing zcal and EventTimer.io.
EventTimer.io's answer:
Most countdown tools are either too basic (a single timer with no sharing) or too expensive for what they offer. EventTimer bridges that gap, it works instantly in the browser with zero signup, yet scales up to a full multi timer event manager with live synchronization across devices.
EventTimer.io's answer:
EventTimer gives you professional event timing features at no additional cost. Compared to Stagetimer, the leading paid alternative, EventTimer is 55 to 60% cheaper while offering a far more generous free tier. You get live sync, shareable presenter and audience views, embeddable website countdowns, and a full event rundown manager. No installation, no plugins, just open a browser and go.
EventTimer.io's answer:
Event organizers managing multi session agendas, educators who need classroom and exam timers, presenters keeping talks on schedule, fitness professionals running timed workouts, and livestream directors coordinating productions. It also serves anyone who just needs a quick, reliable countdown without downloading an app.

There's an even a freer alternative, not FOSS though. http://zcal.co It also allows connection to multiple calendars. - Source: Hacker News / over 3 years ago
