EventTimer is a free, browser based professional event timing solution built for anyone who runs events, presentations, classes, or live productions. It works instantly in the browser with no signup, no installation, and no credit card required.

At its core, EventTimer offers three timer modes (countdown, stopwatch, and alarm) with millisecond precision. But where it really shines is the Event Manager, a multi timer hub that lets you organize complex agendas with multiple timed sessions, auto calculated rundown schedules, and one click switching between segments. Think conference schedules, workshop agendas, or multi room events, all managed from a single workspace.

Key features include: - Real time live synchronization across unlimited viewers via shareable links - Fullscreen display mode optimized for projectors and stage screens - Presenter vs. audience views with role based controls - 40+ preset timers across 8 categories (productivity, presentations, fitness, education, cooking, games, wellness, meetings) - Embeddable website countdown widgets for landing pages and product launches - Mobile responsive, works on any device

Questions & Answers

As answered by people managing EventTimer.io and Kalkulator Pro.

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.
