Think conference schedules, workshop agendas, or multi room events, all managed from a single workspace.

Questions & Answers

As answered by people managing Sli.do and EventTimer.io.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.
