A countdown app for events, goals, and everything between

Track countdowns to the moments that matter

Chrono Countdown turns birthdays, trips, anniversaries, launches, school dates, and personal milestones into a clear timeline you can check at a glance. It is a countdown timer app for iOS, Android, and the web, built for anticipation without the clutter of a traditional calendar.

More anticipation. Less date checking.

Create an event in seconds, choose a cover, set the date, and watch the time update live. Chrono works locally in your browser before you create an account, so you can start immediately. When you sign in, your countdowns can sync across supported devices while remaining private by default.

For moments worth sharing, make a countdown public or invite specific people by username. Follow public holidays and community events, add comments, and keep tracked countdowns beside your own. Recurring dates move forward automatically, while reminders help make sure the moment never arrives unnoticed.
